Abstract: Fertilization has a dominant influence in sugar beet production technology. Results of these investigations are
achieved at stationary trial on Rimski Šančevi (Novi Sad, Serbia), which was conducted at 1982 on chernozem soil type,
subtype on les, and carbonate variety, middle deep form. Organic and mineral fertilizers, with the increased nitrogen
doses (from 50-200 kgNha-1) and its effect on the yield and quality of sugar beet were investigated in this trial. At
variants where organic fertilizers were used, root yield was higher from 2.4 to 4.6 t/ha-1, but sugar percentage was lower
for 0.39%, or it was at the control level. Percentage of sugar utilization was also at the control level or even lower for
0.24 and 1.19%. Sugar beet yield at variants with organic fertilizers was higher for 160, 360 and 510 kg/ha-1 in relation
to variants were only mineral fertilizers used.

Abstracts.The best known and most remarkable example of continuous production in Hungary is the Westsik’s crop
rotation experiment established in 1929, which is still in use to study the effects of organic manure treatment, develop
models and predict the likely effects of different cropping systems on soil properties and crop yields. Such experiments
are costly to maintain, but their cost can easily be justified if they serve a number of different objectives and provide data
to improve agricultural practice. The aim of this study is to examine the potential for sustainable agriculture in Hungary,
and to draw attention to the importance of long-term field experiments in the study of agronomic sustainability.
Current concerns about soil and water quality deterioration, the limited availability of fossil fuels, the loss of
biodiversity, the viability of rural communities, and in general the sustainability of modern agricultural production
practices, all point to the need to work out methods of sustainable agriculture. The goal of sustainable agriculture is to
bring together people and resources, to promote an agriculture that is efficient, profitable, socially acceptable and
environmentally sustainable for the indefinite future. The primary objective is to provide a model where the agricultural
system and community are taken into account as a whole, in which agriculture is not separated from the natural
ecosystem of a region. The most critical challenge is to consider the needs of agriculture and society, and to provide an
educational environment for local inhabitants. In order to meet this challenge, we need research that examines the
principles of sustainable agriculture. In this respect, Westsik’s crop rotation experiment provides data of immediate
value to farmers concerning the applications of green, straw and farmyard manure. The experiment also provides a
resource of yield, plant and soil data sets for scientific research, whether into plant and those soil processes which
control soil fertility, or into the sustainability of production. Moreover, maintenance of Westsik’s crop rotation
experiment can also be used to illustrate the value of long-term field experiments.

Abstract: A field experiment was carried out on the experimental field of Cotton and Durum Wheat Research Institute,
Chirpan, during the period 2004-2006. The following varieties were studied: Progres; Neptun 2; Beloslava; Saturn 1 and
Vozhod under four norms of nitrogen fertilization – N0, N6, N12, N18 kg.da-1 – applied only once in the early spring, having
had cotton predecessor. For the two years of research, as well as for the period on the average, the applying of
increasing nitrogen norms changes considerably the grain yield of all durum wheat varieties. N 12 norm proved to be the
optimum whereas the further increasing of the norm results in decreasing of the yield. Vozhod variety proved to be the
most productive, while the least productive was Beloslava variety.

Abstract: In this paper authors determined that the production costs by the farm-lands from the Group II are for 49.1%
higher, although the cost price is for 14.1% lower, due to higher (for 73.9%) crop. The expenditure for the human labor
by the farms of the Group II is higher up to 7.1% than by the Group I, and the productivity is higher up to 62.7%, due to
better technical equipment of the farms belonging to this Group. The profit level (according to the comparative index), is
almost the same by both Groups, due to rather the positive impact of the higher (up to 16.7%) carrot selling price by the
Group I compared to the Group II, than the negative impact of the level of total costs per unit/land by Group II.

Abstract: Romania is located at the North limit of rice cultivation area. The rice could be cultivated in a narrow area of
40 km, from Turnu Severin to Braila, as well as in Banat – Banloc. Although is a tropical crop, the rice has a special
ecological plasticity, fact that allows the crop extension from equator to the latitude of 48 0 N and from the sea level till
1500-1800 m altitude, in areas with temperatures over 10 0C at germination and over 150C during vegetation till
ripening. In Romania, main important are cultivated genotypes which must reach the maturity till autumn hoarfrosts.
Twelve genotypes with variable vegetation period were tested in order to find the most adequate ones from cultivation

Abstract: Barley has a long and intensive tillering period with a far greater stem number produced than the final spike number per
harvest. The formation of a higher number of stems and spikes (total and productive tillering, respectively) is a negative malting barley
trait because it induces smaller and shrivelled grains which considerably reduce its value for malt production. The investigation of the
effect of fertilisation and planting density on the total tillering of spring barley was conducted over a three-year period at the trial field
of the Small Grains Research Centre in Kragujevac. Five two-rowed spring barley cultivars (the A factor) were investigated and they
were: Kraguj, Dinarac, Dunavac, Jastrebac and Novosadski 294. The planting was carried out at optimal dates (February-March).
Three planting densities (B) of 300, 400 and 500 germinating grains m -2 were used. N, P2O5 and K2O were each incorporated at the rate
of 52.5 kg ha-1 by basic fertilising and top-dressing was carried out in the tillering phase using 0, 30 and 60 kg ha -1 N (the C factor)
during the month of April. The average total tillering for all investigated cultivars, planting densities and nitrogen rates in the threeyear research period was 4.17. The highest average tillering for all planting densities and nitrogen rates was established in the
Jastrebac cultivar (4.52), and the lowest one in the Kraguj cultivar (3.93). The planting density increase brought about a reduction in
tillering. The difference in tillering between the planting densities applied, in all three research years, was highly significant. As
opposed to this, increasing nitrogen rates used for top fertilisation induced a tillering increase. A highly significant tillering difference
was recorded in all three years between the control variant N (0) and the rate of 60 kg ha-1 N. The differences between N (0) and N (30
kg ha-1) were statistically significant in the first two study years, and highly significant in the third year. The difference in tillering
between nitrogen rates N (30 kg ha-1) and N (60 kg ha-1) was significant only in the first two research years. In the third research year, a
statistically highly significant interaction between the cultivar and planting density (AxB) was registered, with the Jastrebac and Kraguj
cultivars having expressed different tendencies compared to other cultivars.

Summary: Variability of amino acids composition of 6 barley and 6 wheat divergent genotypes were identified by using
method of chromatography. Concentration of identified amino acids was established by method of spectrophotometry.
Total concentration of free amino acids was determined by standard curved line for tyrosine while concentration for each
amino acid was determined by using of standard curved line for glycine. Qualitative and quantitative analysis of amino
acids showed that glutamic acid, proline, threonine, norvaline, tryptophan, were the most present in seeds of analyzed
cereal species cultivars. Quantity of free amino acid in wheat varies in the ratio from 35 to 92 mg/ml and in barley from
41 to 81 mg/ml. Concentration of glutamic acid in wheat was 6.5 mg/ml and was higher than contents of other amino
acids. In barley cultivars the highest concentration was established for amino acids proline (12.5 mg/ml)

soil types in the variants inoculated, the number of nodosities was significantly larger than in the control variants. The
nitrogen dose N30 applied before sowing resulted in an increase of the number of nodosities on the brown luvic soil; on
the cambic chernozem there were no significant differences compared to the control (N0). The N60 dose resulted in the
development of a significantly smaller number of nodosities on both soil types.

having with biostimulation activity in order to promote them in agricultural technologies. A bacterial (Bacillus subtilis)
and fungal (Trichoderma sp.) biomass has been obtained for which several conditioning modes were studied:
polysaccharides like pullulan, alginate. The bioproducts thus obtained have been tested for their resistance to thermic
and hydric stress. The best results have been obtained in the case of cells alginate immobilized (for thermic stress), and
in pullulan immobilized cells (for hydric stress). We also studied the influence of the immobilized biomass on wheat in
laboratory conditions. The use of microbial inoculants had a positive effect on seeds germination (plus 10-17.00%
comparative the control). Research continues in order to determine the best methods to apply the microbial agents; to
assess their behaviour in the ecologic niche where they are introduced; to develop and to optimize the implementation
technologies and to integrate them with the conventional technologies, as well as to quantify the influence of microbial

Abstract: In order to have maximum efficiency, each technology element applied to a culture has to be completely in
agreement with the characteristics of the plants and soil. Knowing the behaviour type of the plant in different climate and
soil conditions during the vegetation period, we can intervene with technological measures that will eventually lead to
the anticipated effect, the increase of production in agreement with and following the principles of environmental
protection. The paper presents the accumulation of dry phytomass in the autumn wheat, according to the sowing date. In
this regard, the accumulation of dry phytomass was observed (the total epigeous phytomass, and on components of the
total phytomass), in the case of wheat sown in three different periods: the last part of September, October 9 th-10th and the
last part of October. The paper also presents results obtained in what regards the sum of accumulated temperature
degrees for certain vegetation periods.
Key words: wheat, dry phytomass, sowing time, the sum of temperature degrees.

Abstract: During the latest years, farmers have had to deal with a problem in Dobrogea: the presence of broomrape in
the sunflower fields. The main causes of this phenomenon are the fact that rotation is not observed and the use of hybrids
that do not resist to the attack of this parasite. Every year, specialists warn about the appearance of new broomrape
varieties that are more and more resistant. The efficient pest control measures used previously prove to be useless
against the most recent varieties. The paper observes the production behaviour of several sunflower hybrids
recommended to be cultivated in Dobrogea, considering both the resistance to broom rape attack and a few productivity
elements.
Key words: sunflower, broomrape, resistant hybrids, rotation.

Abstract: The level of production is determined by the interaction between plants’ biological limits and by the influence
of technological elements applied. Upon harvesting we made measurements concerning the values of some pheno-typical
features characteristic of the Attila winter oil rape cultivar under study. The main components of the yield in winter oil
rape are the number of main ramifications per plant, the number of siliques per plant, the number of seeds per silique,
the number of plants per m2, and the average volume of a seed.

Abstract: The constitution of mountain meadows vegetation is stricken by numerous factors, among them an important
part played by the applied management. The A. montana meadows are the result of the application for a long time of an
extensive traditional management. The absence of the maintenance works (especially the fertilization) and the
exploitation only by grazing determine the powerful setting in of some species like: Vaccinium myrtillus, Vaccinium vitisideae, Luzula luzuloides, Deschampsia flexuoza etc. The application of the maintenance works and the exploitation by
mowing or by a mixed system favours the extend of some species, like: : Agrostis capillaris, Festuca rubra, Trisetum

Abstract. It is well-known that elastic finger lifting drums, besides remarkable construction and functional features
(simplicity of the construction, high safety in operating, low volume, and high adaptability) also have a disadvantage: a
relatively specific low working capacity because of the low advance speed. In order to increase working capacity, in the
conditions of maintaining quality indices at admissible levels (low loses of forage, avoiding detachment of leaves and
inflorescence from plant stems, and avoiding the soiling of forage by earth) it is necessary to find solutions for the
increase of the active area of the elastic fingers during the raking process.

Abstract: Very different soil and climate conditions that determinates grassland formation and the powerful anthropic
influences determinate a great variability from botanical composition point of view but also from forage yield and
quality. Having in view the low level of the permanent grasslands yield there is needed the applying of a technical and
organisational measures complex with the purpose of the improvement of nutritive quality and its rational use.
Depending by these aspects the vegetation can be changed fundamentally concerning the improvement or depreciation of
botanical composition in a very short time.

Abstract: The existence of small turf surfaces in the front of every house is in many neighbourhoods from big cities the
postponing in modernity of the spaces between house and road from rural areas, which are dominated by grass. In fact,
turf has become an essential an irreplaceable element for recreation and sport. Also, the turf is providing a soil
stabilisation, protection against erosion due to its roots system and other features of the component grasses. Turf
presence on soil stops water evaporation, is maintaining a lower temperature of soil due plants evapotranspiration.
Extra, a considerable advantage of turf is that the uneven surfaces and land imperfections are transformed in landscape

Résumé: L’amélioration des prairies permanentes exploitées de manière extensive est un problème très actuel en
Roumanie. Une de pratiques fréquemment utilisée est la fertilisation sous différentes formes (organique, minérale et/ou
mixte). Dans le cadre de ce travail on essaye de comparer les trois systèmes de fertilisation sur une prairie permanente
implantée sur un sol acide avec le pH 4.9, situé à Vârciorova dans le département de Caraş–Severin. Sur les trois
systèmes de fertilisation on observe une augmentation de la matière sèche (MS) pour toutes les variantes de fertilisation
comparativement au témoin. Les productions de matière sèche pour les trois systèmes sont comprises entre 2.06 t/ha (V1,
fertilisation organique) et 4.09 t/ha (V10, fertilisation mixte) mais ces valeurs ne sont pas significativement différentes
entre les trois systèmes de fertilisation.

Résumé : La gestion des prairies permanentes situées dans des régions montagneuses est un des principaux enjeux pour
le développement de systèmes de production durables pour lesquels les contraintes majeures sont à la fois économiques
et environnementales. La fertilisation organique peut être une des solutions pour obtenir une production suffisante de
matière sèche à un bas prix. Dans ce travail on se propose d’étudier la dynamique de la matière sèche sur une prairie
permanente implantée sur un sol acide (pH = 4.8) exploitée par fauche sur laquelle on a appliquée deux types de fumier
(ovin et bovin) en différentes doses. Les résultats obtenus sur notre dispositif après trois années d’expérimentation
montrent que les productions maximales ont été obtenues pour les variante V2 et V5 (10 t/ha annuellement fumier ovin et
20 t/ha tous les deux ans fumier bovin respectivement).

Abstract: In South-East Hungary the weather conditions generally are dry in spring so the efficacy of preemergence
weed control methods is not sufficient. Most preemergence herbicide requires 10-20 mm of precipitation within 2 weeks
after application to increase their effectiveness. Experiments were conducted in Hódmezővásárhely, southern part of the
Great Hungarian Plain in 2005 and 2006 to study different postemergence weed control technologies in small plots in
maize. The characteristic weeds on the experimental plots were the Sorghum halepense, Datura stramonium,
Chenopodium album, C. hybridum, and Amaranthus retroflexus. The efficacy of the herbicide combinations against
dicotyledonous weeds was very similar in the two years. Herbicide treatments contain nicosulfuron combined dicamba +
bentazone or mesotrione or tritosulfuron + dicamba and rimsulfuron + dicamba combination controlled dicot weeds
with a very good result. The efficacy of foramsulfuron + isoxadifen-ethyl against Chenopodim species was moderate,
while florasulam + 2,4 D killed these weeds with a low level of efficacy. In 2005 - when the weather was hot and rainy 2
weeks before and after the treatment - we observed an excellent weed control result against Sorghum halepense. The
efficacy of the herbicides was a bit poorer in 2006 because of the cold and too rainy weather. None of the examined
herbicide combinations injured maize. At harvesting yield was measured and the data was analysed by variance
analysis. Significant yield loss of maize was observed caused by the high weed infestation on those plots where the
herbicide effect against weeds was low and on the untreated plots.

Abstract: Providing enough amounts of food, for fast growing world population, is one of the largest problem of modern society.
The data from Food and Agriculture Organization of the United Nations (FAO, 2006), are showing us minatory number of
people on the planet today (approximately 7 billion). Due to intensive development of science and technology during the last
decades, a large number of very effective and inexpensive pesticides were synthesized, which is with increase of arable land
areas, influenced on total agricultural production growth in the world. However, production of enough quantity of food (as well
as food surplus, whose storage is very expensive) is a characteristic of developed countries, while so called third world
countries still have hunger problems. The period of highly chemicalized intensive modern agriculture, in which pesticides are
having main role, enabled triple of yield per sowed hectare, and on the first sight gave positive solution of hunger problem.
However, excessive and unreasonable use of pesticides and other chemical preparations brought us to the extreme degradation
of all environment’s elements (soil, water, air, flora and fauna). Destruction of natural resources with permanent pollution, in
the end, lead to decrease of yield per hectare and production of food contaminated with pesticides and other materials
dangerous for human health. The philosophy of unlimited growth and development must be changed with new philosophy of
sustainable development, which considers development balanced with needing of nature protection. One of the solutions, can be
agricultural orientation toward organic production, which exclude use of synthetic pesticides in agriculture. Organic
agriculture, as an ideal harmony of environment and agriculture production, can actively help the process of sustainable
management of natural resources. Healthy food, produced by methods of organic agriculture, in balance with biologic and
ecologic regularity, enables the sustain of human population viability. Therefore, the future of next generation and survive of
human species largely depends on activities we take today.

Abstract: Helminthosporium turcicum Pass. is the main leaf parasite of corn that encounters problems for plant
inbreeders, and the cultivators suffer average loses in comparison with other continents as is North America where the
loses are sometimes very important. In the experimental field from Şagu (Arad County area), we have realised a
comparative crop with eight corn hybrids produced by “Afumaţi Pioneer Research Centre” of “Pioneer Dupont
Company” during 2006. This comparative crop is analysed under the aspect of Helminthosporium turcicum attack. For
the data registered during 10-12 September, we have a repetition with 10 plants, and after eliminations, there remained
116 plants that have entered in experimental calculus. Observation phenophase is ten leaves. Classical study
methodology refers to the aggressiveness as referring to corn plants, and the new study methods are having in view to
establish these parasitic features at the leaves level, following this the aggressiveness for a hybrid is the average from the
plants and leaves level. This method appreciate more accurate the hybrids comportment with very important aspects for
inbreeders and corn cultivators. PR 37D25 hybrid is considered by “Pioneer Dupont Company” as tolerant for
Helminthosporium turcicum and Ostrinia nubilalis being considered good as control variant. Fungus aggressiveness for
PR 39D81, PR 38R92, PR 38A24, PR 37D25, PR 37M34, PR 37 W05, PR 35P12, PR 36R67 hybrids is average being
comprised between 43.19% (control variant) and 87.1% in case of extra-early hybrid PR 39D81 at plants level. At leaves
level the fungus aggressiveness is almost a half (40.7-59.2%), and on hybrids level the amplitude variability is 34.9360.75%, after the new study method. Is very important to include the corn hybrids on a scale as resistant, medium
resistant, or tolerant and sensitive, and is also important to compare them with the aggressiveness values from the plants
level. Analysed hybrids are not containing major genes (Ht1, Ht2, Ht3, and HtN), minor, or their combinations. The
tolerance of PR 37D25 is genetically controlled, but not with resistance genes.

Abstract: Concerning plant resistance for diseases, respectively of the genes is activating as it follows: non-specific
genes – non-specific resistance and specific genes – specific resistance, this classification being realised on the
background of “genes functionality”. In this work are presented models of non-specific genetic resistance that has as
models synthesis works “SA, JA, ethylene and disease resistance in plants” by XINIANG DONG and “Infection
structures of biotrophic and hemibiotrophic fungal plant pathogens” by SARAH E. PERFECT, JONATHAN R. GREEN.
Non-specific or conservative resistance is expressed with the help of plant phenotype with the help of a response of
systemic acquired resistance – SAR and induced systemic resistance – ISR. SAR path that helps the plants to avoid
diseasing with powdery mildew are: hypersensitive resistance (RH), salicylic acid (SA), jasmonic acid (JA), ethylene,
calmodulin (CA++) and perhydrole (H2O2). ISR is a plant response for physiopathic factor, non-infectious and for the
infectious factor. During 2003-2004 at S.C.D.A. Lovrin where implemented 27 wheat varieties in SAR and ISR and we
have concluded next aspects: resistance is determined by non-specific genes and their activity are leading in time in
wheat plant cells defensive proteins for pathogen factors (PR) preserved by PAMPs (Pathogen associated molecular
patterns) and salvation as in case of physiopathic factors. These two variants (defending and curing) are implying to
provide biological and organic wheat harvests, qualitative and quantitative.

Abstract: Biotrophic fungus Blumeria graminis in wheat can produce quantitative and qualitative loses. In these
condition prevention and control of this parasite fungus can be realised through the application of the modern concept of
plant protection “Integrated plant protection”. This complex system provides constant qualitative and quantitative yields,
and the non pollutant subsystem that is also economically is “genetic control”, respectively the genetic resistance of the
wheat plants. Wheat varieties are avoiding the incidence of powdery mildew, or are diminishing the fungus
aggressiveness and virulence through structural and genetic mechanisms. Structural mechanisms are imprinting a false
resistance of a pseudoresistance, or non-specific that is provided by the presence in wheat varieties by pre-existent
structures as is the cuticula, epidermal cells membrane and his impregnation of it with different organic substances,
ectoderm and pilosity and “de novo” postinfectional structures as are apresoria – MA and haustorial MAT-EH. In fact
the glycoproteins are produced by the wheat varieties genes. These structures are determined by pseudoresistance being
in fact the defending responses of the wheat varieties (Dor, Falnic, Gruia, Gloria and Bercsy studied during 2003-2005)
to the action of evolutionary and conservative genome of the fungus – PAMPs, and also by the activity of resistance
genes Pm (powdery mildew).

weeding degree (over 92.00%) compared to the control treated with the classical product SDMA Super 1 l/ha,
concerning both total weeding and horse thistle were the result of applying the herbicide Dialen Super 0.90 l/ha and
Premiant 1 l/ha, respectively. On all the trial plots, 30 days after application, and particularly 60 days after application,
there was a regeneration trend in horse thistle shoots. All the herbicides we tested were very selective for the winter

Abstract. Maize, the most widespread tillage crop in Romania, is known as being very sensible to weeding, particularly
during the first stages of vegetation. A problem-weed in maize crops is the species Xanhium strumarium L., popularly
called mouse ear or thistle. In this paper we aim at establishing some of the most efficient pre-emergent herbicides in the
control of this species in the grain maize crops. Research was carried out during the years 2005 and 2006, at the
Didactic Station of the Agricultural and Veterinary University of the Banat in Timişoara (România) on a cambic
chernozem. The trial was mono-factorial with four replications. The best results in the control of the species Xanhium
strumarium L. were ensured by the herbicide Cambio-2.5 l/ha (96.80% in 2005 and 95.20% in 2006), closely followed by
the herbicide Premiant-1l/ha. None of the tested products resulted in phyto-toxicity symptoms in the cultivated maize
hybrid, Florencia (P3573). Grain maize yields were visibly influenced on one hand by some of the performances of the
herbicides in the control of the mouse ear and on the other hand by the climate conditions of the two years, the year 2006
being more favourable for maize crop.

Abstract: The objective of our researches was to identify the varieties with associated resistance to diseases and pests –
an important objective for the rationalizing and reduction of the chemical treatments, production expenses and,
implicitly, of the environmental pollution. We have observed a significant presence of the pest Leucoptera scitella Zell in
the apple orchard belonging to the Didactic Station Timisoara, in 2006. This has determined us to begin the researches
upon the apple tree behaviour. The observations carried out during the last decade of August, when the attack was
maximal, have led to the conclusions that: the varieties Florina and Pionier were slightly attacked, proving a good
resistance (RB) towards the attack of this pest, the varieties Generos and Romus were moderately attacked (RM), and the
variety Ionathan was strongly attacked (RS).

Abstract: The effectiveness of NeemAzal-T/S insecticide used against Ips typographus L. bark beetle was assessed by
using the method based on solution injection with 4% concentra-tion in spruce tree trunks. The method is nonpolluting
both concerning the insecticide as well as the way of solution administration (the solution does not get in contact with
the environment).The effectiveness on pest larva control was of 90% at 2-2.5 m trunk height, 87% at 4.5 – 5 m, 79% at 7
-7.5 m, 82% at 9.5-10 m, 85% at 12 -12.5 m, 62% at 14.5- 15 m and 75% at 17- 17.5 m. Considering that none of the
individuals managed to undergo pupa stage it has been assessed that the insecticide efficacy on pupae was of 100% for
all samples. Nevertheless, such studies are still in their initial stage and are the first to be performed in the country the
method is still requiring improvement. Our studies clearly demonstrate that spruce trees may be protected against Ips
typographus L. beetle by means of such methods.

Abstract: To establish the flight phenology of the insect Pityogenes chalcographus L. and the development of
descendence on the year 205, were been delimited experimental points in representative forest stands with spruce from
Nădrag-Padeş area. After recorded captures at pheromonal traps baited with aggregative synthetic pheromones we
establish that the insect has two flights on year. The first flight is in April, May and June (76-94% from the flight on all
growing season), and the second flight is in July and August (6-24% from the flight on all growing season). Has been
established the length of each flight and the top of flight. Has been established the populations level. After periodically
bark the trap stakes, as favourable place of oviposition, has been established the date of first entering of parents beetles,
the date of appearance of first eggs, the length of egg, larval, pupal stadium, the date of appearance of first young adults
and first mature adults, in forest stands al different altitude. Has been established that the insect have two generation on

Abstract: Air temperature, rainfalls, air relative humidity, dew, nebulosity and wind are climatic factors that are acting on
powdery mildew-wheat tandem. Literature offers pieces of information only for the relationship with temperature and rainfalls.
They have proposed a detailed research on mentioned climatic factors on fungus virulence during 2003-2005 with the help of a
complete statistic interpretation with the help of SPSS programme. For statistic analysis they have introduced the data of those
six climatic parameters and the fungus virulence data on 27 winter wheat varieties cultivated in the experimental plots from
S.C.D.A. – Lovrin. Realised researches are allowing studies concerning the elaboration of a prognosis and warning programme
for wheat powdery mildew control. They have worked with decade averages for all analysed variables. In model correlation
determining they have used the exclusion of analysed factors. There have resulted five regression models that demonstrate the
existence of interrelations among studied variables. For all the models the correlation coefficient is greater then 0.7 that shows
the existence of interdependence among those analysed variables. Conclusions were next: the greatest influence on the increase
of Blumeria graminis f. spec. tritici attack intensity, in conformity with the data obtained after the recording of empiric data is
due to the next factors: relative humidity, rainfalls and temperature. The factor that cannot be excluded from the attack intensity
analysis and influences conidia dispersal of the fungus is the wind.

Abstract: Fungicides effect on powdery mildew and wheat yield is studied in an experience placed at S.C.D.A. Lovrin. The
purpose of this study is to register if the yield differences among treated variant and tester (no treated) are significant. In this
experience are investigated and treated 25 winter wheat varieties with different reaction in case of Blumeria graminis f. spec.
tritici attack (R – resistant, MR – medium resistant, S – sensitive). Because in experience are used some fungicides those 25
winter wheat varieties are divided in four groups: three groups with six varieties and a group with seven varieties. There is
tested the fungicides efficiency on the background of natural infection. All the data are statistically analysed. The treatment with
fungicides (fenpropimorph and epoxyconazole, triflumizol and clorotalonil, ciproconazol and propiconazol, azoxystrobin) from
this experience is executed at 49-50 growth stage (after Zadocks scale – ear emergence). The disease where present in
experimental field during treatment applying. Fungicides efficiency is appreciated as: very good for fenpropimorph and
epoxyconayole in case of Arieşan sensitive variety and very good for medium resistant varieties from first varieties group; very
good for triflumizol and clorotalonil (Boema sensitive variety) and totally efficient for the other varieties from second group;
very good and totally effective for ciproconazol and propiconazol (Izvor, Turda 2000, and Ciprian sensitive varieties); satisfying
and good action for azostrobin case of Partizanka and Bezostaia sensitive varieties. The yields obtained in the case of treatment
experience are superior in comparison with non-treated variant; these proving that the fungicides from mixtures are biologically
compatible and are influencing positively plants biochemistry in a positive way.

Abstract. An important aspect at the production of birds – foot trefoil seed, besides the insurance of favourable pedoclimatic conditions was the resistance of that plant to the diseases and pests. One of the most important pests, which
produced the biggest damage is the birds’foot trefoil thrips (Odontothrips loti Hal.). Although mentioned in the specific
literature, that pest was a little studied in our country and in that context, the paper emphasized the ones experimental
data concerning the dynamics of the birds – foot trefoil thrips, adults and larvae. The entomological material, which
constituted the object of this study, was collected from one agro ecosystem, at the Didactic Station from Timişoara. The
experimentation was placed after the standard method according to the specific literature indications, and the samples
were collected with the help of metrical frame of 0.5/0.5 m. The collected insects were prepared, determined and
preserved in the Entomology Laboratory of the Agricultural University from Timişoara. Through the monitorizations,
which tacked place from 48 hours to 48 hours, resulted that the first adults signal was registered in the second decade of
the June month. The biggest number of the catch adults was registered in the date of 28.06.2006, 42 samples, and the
biggest number of collected larvae was registered in the date of 10.07.2006, 13 samples. The last captures were
registered in the second decade of the July month. The knowledge of the dynamics characteristics of the thrips
populations contributes to the establishment of the best moment of applying the treatments concerning the integrated
controlling of the mother tree birds – foot trefoil pest.

Abstract. At the birds – foot trefoil crop one of the most important aspects is the production of seed, so for the realisation
of an integrated protection of a superior quality seed and in a great quantity, is necessary to know the insects that
produce the most important damages to this crop. One of these insects is the birds – foot trefoil thrips (Odontothrips loti
Hal.). For realizing the chemical treatments in the years 2004 and 2005, the experimental field was placed at the
Production and Investigation Station for the Fields Crop from Timişoara. The experimental field was formed from 3
repetitions, each repetition having 7 variants. The usage of pesticides was the same in the all two years of the
experimentation, as follows:; V1 – treated with Fastac 10 EC; V2 - treated with Mospilan 20 SP; V3 - treated with
Calypso 480 SC; V4 - treated with Confidor 70 WG; V5 - treated with Actellic 50 EC; V6 - treated with Decis 2,5 EC; V7
– untreated testifier. In the year 2004 the most efficient product in controlling the birds – foot trefoil thrips is the Actellic
50 EC product, which had an efficaciousness coefficient of 90% and the lowest results were obtained after the usage of
Confidor 70 WG product, with an efficaciousness coefficient, it was of 4%. In the year 2005 the best results were
obtained after the usage of same product Actellic 50 EC, which had an efficaciousness coefficient of 69,5%, and the
lowest results were obtained after the usage of Mospilan 20 SP product, with an efficaciousness coefficient of 43,3%

Abstract: The anthropic activity determines the expansion or reduction of the habitats of plant species. The commercial
exchanges of seeds and the acclimatization ability of the segetal species to various pedoclimatic conditions, may
determine the exceeding of adventive species level and move towards species with a wider habitat, often cosmopolite
species. Under this aspect, it is chronologically and ecologically analyzed the species Ambrosia artemisiifolia which can
become problematic in the Western Plains of Romania in the years to come, considering its tendency to develop from a
ruderal into a segetal species.

Abstract: Diabrotica virgifera virgifera (western corn rootworm) is certainly the most damaging pest among the pest
species found in corn crops from the western part of Romania. Attack frequency of this pest is analyzed in an experience
placed near Şagu locality – S.C. Agrogil, Arad County area. The purpose of this work is to establish the damages
produced by Diabrotica virgifera virgifera pest larvae on corn plants. In this way, during 2006 there were studied eight
corn hybrids from different maturity groups with American origin. These researches will allow us to establish the role of
this pest on the amplifying of corn pathological systems under epidemic view (Zea mays - Fusarium roseum, Zea mays Ustilago maydis, Zea mays - Helminthosporium turcicum, pathogens monitored during 2006). After the result analysis
we can conclude the next: Diabrotica virgifera virgifera larvae attack amplitude varies between 5.17% and 13.78%,
values registered in case of PR 36K67 and PR 39D81 hybrids. Control variant is represented by PR 37D25 a half-early
hybrid and it has shown a 5.45% attack percentage. Statistically are registered very distinctively significant and
distinctively significant attacks in case of PR 39D81, PR 38R92 and PR 37M34 hybrids in comparison with the tester.
The other hybrids show small differences in comparison with the tester, not statistically provided, but these differences
are important from practical point of view.

Abstract: Corn hybrids PR 39D81 (extra-early), PR 38R92 (early), PR 38A24 (half-early), PR 37D25 (half-early), PR
37M34 (half-early), PR 37W05 (half-early), PR 35P12 (half-late), PR 36K67 (half-late) are tested in Arad County area
(Şagu – SC. Agrogil) for natural infection with Fusarium roseum and Ustilago maydis parasite fungi. The company
specifies tolerance for Ustilago maydis in case of PR 38R92 and PR 37W05 hybrids, but they have any reference for
Fusarium roseum, this situation influencing our decision concerning the realisation of this study. Fusarium roseum
fungus aggressiveness oscillates between 4.79% and 45.0% registered in case of PR 35P12 and PR 38R92. In
comparison with PR 37D25 tester variant are registered infection increases statistically provided by PR 38R92 (early),
PR 37W05 (half-early) and PR 36K67 (half-late). In case of PR 35P12 is registered a decrease of infection from
statistical point of view, this hybrid maintaining also the signification trend in comparison with the experience average (25.77%). Ustilago maydis attack is extremely damaging in hybridising plots, but in our case is low except control variant
– PR 37D25 where the aggressiveness is 8.54% and PR 37W05 half-early hybrid (14.5%). In the case of these two
variants, the results are statistically provided as very distinctively significant in comparison with the experience average
that is 7.58%. There are not registered an attack in case of PR 38A24, PR 37M34 and PR 36K67, which will be studied
during the next years. There is recommended special protection measures for kernels affected by Fusarium roseum
during storage and Ustilago maydis in hybridising plots and especially in case of ice drops falling down.

ANALYSIS OF PER CAPITA GREENHOUSE GAS EMISSIONS
IN EU-25 COUNTRIES

Abstract. The European Union is committed to global efforts to reduce the greenhouse gas emissions from human
activities. In the first step countries accepted to reduce greenhouse gas emissions by around 5 % compared to 1990
levels, but in the longer-term, global emissions of greenhouse gases will need to be reduced by approximately 70 % and
it forces the countries to update national emission inventories each year. An analysis of per capita GHG emission has
been made with 25 member state of EU responsible for about 41 % of total greenhouse gas emissions. The 15 member
states that made up the EU until 1 May 2004 are committed to reducing their combined emissions of greenhouse gases by
8 % from 1990 levels by the end of the Kyoto Protocol’s first commitment period 2008–12. The 10 new Member States
are not covered by the EU target but have their own reduction target of 6 % or 8 % under the protocol, except for Cyprus
and Malta, which have no targets. Many of the EU countries have greenhouse gas emissions greater than 6 t CO2-eq/cap.
In 2004, the most important sources of greenhouse gas emissions in the EU-25 include energy industries (electricity
sector and refineries) (28 %), transport (21 %), industry (without energy sector) (20 %), households and SMEs (17 %),
agriculture (10 %) and other sector (4 %). Directive 2003/87/EC established a scheme for GHG emission allowance
trading within the community in order to promote reductions of GHG emissions. EU scheme allows companies to use
credits from Kyoto’s project-based mechanisms, joint implementation (JI) and the clean development mechanism (CDM),
to comply with their obligations under the scheme. This means the system not only provides a cost-effective means for
EU-based industries to cut their emissions but also creates additional incentives for businesses to invest in emissionreduction projects in developing countries. The transfer of advanced, environmentally sound technologies to other
member states and developing nations, gives tangible support to their efforts to achieve sustainable development, but per
capita GHG emission data indicate the importance of grouping to share reduction between global regions and countries.

Abstract: The paper is based on the research carried out in the second cycle of the experiment placed in Oradea in 1999.
The use of lupine mixed with oat determined the improvement of the macrostructural stability compared to lupine pure
crop. The use of the mixture also determined the improvement of other physical parameters, slightly improvements of the
chemical parameters of fertility of the soil, the improvement of the enzymatic activity; as a result, the soil quality
enzymatic index improved, a value of 455 compared to one of 441.49. The green manure pure crop ensures a 100% rate
of success; the start second crop takes risks when made after 10th of July. In average, during 2004 to 2006, the lupine +
oat variant assured statistically yield gain in the maize crop, compared to the lupine pure crop variant; these yield gains
were registered both in the wheat-maize crop rotation and the crop rotation which included clover; the yield gains were
also registered in the backgrounds studied (N0P0K0; N90P90K60). The maize’ water use efficiency had higher values in the
variant fertilized with lupine + oat in both crop rotations and both background. The results obtained reveal that the use

Abstract: This study present the environmental impact of the industrial pig farms and the high pollution degree of the
environmental factors (water, air, soil and people). Reprehensible management and carelessness about the potential
dangers of the waste and the failure to install decent pollution control equipment and treat the waste resulted in
violations of the permitted limits for phosphorus, faecal coliform and other pollutants. One way that pig farms waste
pollutes is through the sprayfield system, which is supposedly meant to fertilize crops. But often too much of the untreated
liquid manure is sprayed, resulting in crop damage and contaminated soil, groundwater as well as pose a serious health
risk to the small segment of the population subject.

Abstract: The paper has as aim the cellular and biochemical identification of some proteins (phytochelatins and isophytochelatins) able to bind the cadmium ions. For this, cell suspensions of root callus proceeded from an Agrostis tenuis
ecotype (harvested from a metalliferous area, polluted with heavy) were obtained. The cell suspensions were treated with
different cadmium concentrations. One can ascertain that the Agrostis ecotype, from polluted area, has the ability to
synthesize phytochelatins and, it manifests an increased tolerance to cadmium ions (solution concentrations of 100 μM).
One can conclude that phytochelatins synthesis has an important role into plant tolerance to cadmium.

Abstract: In a period of 12 weeks, samples of white poplar bark (Populus alba), naturally covered with lichens of the
Xanthoria parietina and Physcia aipolia species, and were polluted under lab conditions with different levels of Zn and
Pb. The pollution was done through the watering and nourishing solutions and the level of the two pollutants varied
between 20 – 240 mg Zn/L and 10-120 mg Pb/L. The reaction and adaptation mode of the two lichen species was
assessed through the phytomass abundance study, evaluated according to the bark surface covering degree. The watering
performed to pollute and nourish was done twice a week. Measuring the surface covering degree was done through
planimetry at 3, 6, 9, and 12 weeks. Our results evidenced great sensitivity of the Physcia aipolia species to high
pollution levels of Pb and ZN. The covering degree is reduced after 3 weeks to 60%, to 95% after 6 weeks, and at 9
weeks, this species completely disappeared. After an accommodation period of about 3-4 weeks, when the covered area
remained the same, the covering degree of the surface by the Xanthoria parietina species increases by 10% at 6 weeks,
reaching 15% at 12 weeks. These results lead to the idea that the careful study of the lichen abundance may offer in an
easy way signal-news about the gaseous pollution level of the environment.

Abstract. In this paper work, we present the results of our studies concerning the effects of the herbicides linuron,
dimetenamid and treflan upon the symbiotic nitrogen bacteria applied in seeds. We have tested herbicide action for 4
concentrations: normal concentration – the normally recommended herbicide dose, double concentration (2x normal
dose), triple concentration (3x normal dose), and half of the recommended dose (1/2x normal dose). The results achieved
made evident that strains have different reaction to linuron and dimetenamid, and these reactions are not correlated with
the concentration. We may explain this situation through the different strain capacity of tolerance under the action
exerted by these herbicides.

Abstract. The industrial process of producing magnesium carbonate and oxide from dolomites by carbon dioxide
leaching generates calcium carbonate as waste. Besides calcium carbonate, this precipitate contains magnesium carbonate,
which can be useful in agriculture as a soil amendment and fertilizer for low fertile acid soils. The paper shows the effects of
soil treatment with four different doses of industrial waste concerning the soil reaction and calcium - magnesium content,
simultaneously with the growth process of green oat plants and their calcium - magnesium uptake. The obtained results
indicate that soil reaction turns from acid to neutral, while the established increase for calcium soil content reached 51% and
260% for magnesium content, both generated by the highest experimented waste dose. For green oat plants, the results
showed an increase by 117% for calcium uptake and 72% for magnesium uptake. The influence determined on the growth
reveals a beneficial effect on germination and number of risen plants, a taller size of plants as well as a decrease of dry matter
content at harvest time.

Abstract: Two short definitions of Remote Sensing might be presented as follows: “To study or measure an object
without being in physical contact with it” or “feeling without touching”. As defined above, the term generally implies
that the sensor is placed at some considerable distance from the sensed target, in contrast to close-in measurements
made by "proximate sensing." sometimes given as "in situ" sensing. Remote sensing means aerial photography too.
Aerial platforms are primarily stable wing aircraft. Aircraft are often used to collect very detailed images and facilitate
the collection of data over virtually any portion of the Earth's surface at any time. The scale and quality of the data
collected is affected by several factors including, but not limited to, altitude of the aircraft, position of the plane, and the
quality of the photographic equipment used.

Abstract Noise affects population from physical and psychical point of view. If the 40 dB level noise provokes sleeping
disorders , a 55 dB level noise creates significant disturbance. At greater levels of 65 dB, noise affects seriously human
health, acting in the first place on cardiovascular system and could get to (or aggravate) affections as hypertension,
ischemia and others. At levels over 80 dB noise produces progressive and cumulative deterioration of hearing even if is
for short time exposure, like minutes. These aspects are underlining impact exposure adjustment importance at noise on
population and establishing clear limits for level noise. In general the 50 dB value is considered as being the most
adequate maximum limit admitted during day time for equivalently exterior buildings noise level, in urban environment.
In this paper we try to emphasize the significant impact of road traffic in the urban noise generation and the fact that
urban noise is the only environmental factor that degrades its quality with the passing of time..

Abstract. In this paper, we approach an issue of importance in ecological reconstruction related to the dynamics of plant
species on fallows in the Faget – Margina – Cosava area (Timis County). The area under study covers 400 km2 if we take
into account all the fallows aged 1-7 after grain or tillage crops. In the study of the flora, we used the two steps – field
and lab – and phyto-coenologic research in the area are based on the principles of the Central-European floristic school
with broad application in the study of the vegetal cover in Europe and applied for the first time in Romania by Borza
(1984). As a result of the study on the sampling areas we managed to inventory the superior plant species on the fallows
and the characteristics of the flora and vegetation (number of families, number of species, height of the vegetal cover,
stratification, and mosaic-like configuration), and phyto-geographical, biological, ecological, and economic indices. In
this paper we also refer to the evolving trends of the phyto-coenoses, the changes it undergoes, its dynamics, and manmade activities

Abstract. The aim of this study was to evaluate the influence of conventional and reduced tillage and fertilization on
seasonal dynamics of basal respiration, soil organic matter and total content of nitrogen in topsoil layer by growing of
common pea. The results refer to 2001-2003 years. The experimental site belongs to warm and moderate arid climatic
region in the south-west of Slovakia. Common pea was growing in crop rotation: clover (Trifolium pratense L.) - winter
wheat (Triticum aestivum L) - common pea (Pisum sativum L.) - maize (Zea mays L.) - spring barley (Hordeum vulgare
L.) under different tillage and residue management practices. Three fertilization management practices as follows: 0zero level without fertilization, F- mineral fertilizer calculated to the designed yield level, PR - incorporation aboveground plant material with mineral fertilizer for the balance equilibrium level. Mouldboard ploughing (0.2-0.22m) and
disking (0.10-0.12m) was used. The soil samples were collected from the 0.075m topsoil layer three times (spring,
summer and autumn samples). No significant differences of soil basal respiration between conventional (22.7
mg/1000g/day) and reduce tillage (23.4 mg/1000g/day) in topsoil layer has been noted. The average content of C ox was
in interval 1.04%-1.16% without significant influence of tillage treatments. The significant changes of C: N ratio were
influenced predominantly by variability of Nt content. The high level of basal respiration and flux of CO 2 from
unfertilized zero treatments and treatments with mineral fertilization (23.4 - 22.07 mg/1000g/day) are serious threat for
the soil organic matter pool from long term perspective.

Abstract. The aim of the study was to determine the main factors influencing the variability of soil moisture under canopy
of maize growing in monoculture and in crop rotation subjected to conventional and reduced tillage treatments. The
experimental sites belong to warm and moderate arid climatic region with long term average precipitation 580 mm and
9.6 ˚C temperature and 173 m altitude. The maize was growing in following crop rotation: winter wheat (Triticum
aestivum L.) – maize (Zea mays L.) – spring barley (Hordeum vulgare L.) – common pea (Pisum sativum L.). The
mouldboard ploughing (conventional tillage) to the depth 0.3 m and shallow loosening to the depth 0.1 m and its
influence on soil moisture in six layer has been evaluated. Samples were taken five times per year with tree replication in
six layers (each 0.1m thick). Seasonal dynamics with influence of weather and growing crops have been ascertained.
According three year field trials we confirm no significant differences of soil moisture between primary conventional
tillage and reduced tillage treatments under canopy of maize growing in crop rotation and growing as single cropping.
Total average of moisture content under reduced tillage revealed the less infiltration rate with comparison to
conventional mouldboard ploughing. The highest variability of soil moisture was induced by date of sampling and crop
rotation which is important tool for better management of soil moisture balance under canopy of maize.

Abstract. The study was carried out in the experimental filed of the Maize Research Institute, Zemun Polje, on calcareous
chernozem in the period 2001-2003. The traits of two maize inbred lines (L1–FAO 400 and L2–FAO 600) were observed
in dependence on the two fertiliser variants: No–control without fertilising; Nmin–PK (const.) + fertilising in spring on
the basis of the Nmin method, and forms of applied nitrogen: Urea (amidic form), KAN (ammonium-nitrate form) and
(NH4)2SO4 (ammonium form). The highest amount of (NH4+NO3)–N in the soil (0–120 cm) in the silking stage of maize
inbred lines was recorded in 2002 (72.6 kg ha-1), under the inbred line L2 (84.0 kg ha-1) and in the treatment with Urea
(86.4 kg ha-1). The amount of NH 3 –N and (NH4+NO3)–N in the soil (0-120 cm) measured at the end of the growing
season of observed maize inbred lines was the highest in the second year of investigation (48.9 and 55.8 kg ha-1,
respectively). The application of nitrogen in the amidic form highly significantly affected the increase of the amount of
accessible nitrogen in the soil at the end of the growing period in the inbred L 1 (46.3 kg ha-1), while the application of
different nitrogen forms did not express statistical significance in the inbred L 2

Abstract: Microorganisms are a heterogeneous group of organisms whose enzymatic systems take 60-90% of the total
metabolic activity in soil. Dominance of certain groups of microorganisms affects the processes of soil synthesis and
decomposition and it determines the quality of soil and its applicability for the production of safe food. The nonsymbiotic
nitrogen fixer Azotobacter is an obligate aerobe living in the soil, the rhizosphere and the plant root. The ability of
various strains to fix atmospheric N positively affects plant growth and yields. In this study we have determined the
abundance of azotobacter, fungi, actinomycetes and the total number of microorganizms in sugarbeet rhizosphere.
Simultaneously we studied the effect of application of nitrogen fertilizer, manure and harvest residues. Samples of rhizosphere soil were taken three times in the course of growing season (May, July, September) the ex-periment included
two variants (inoculated with azotobacter and noninoculated) in four fertilization levels (nonfertilized control, 50, 100,
150 and 200 kg N/ha), in five replication. The results of the stu-dy for all four fertilization types and all four levels of
added N showed that azotobacter abundance was higher in inoculated treatments than unino-culated ones. The highest
percentage increases of azotobacter numbers, total microbial abundance and number of fungi and actinomycetes were
recor-ded in the inoculated treatments with barnyard ma-nure, NPK fertilizer, and barnyard manure plus harvest
residues, respectively. In inoculated and uninoculated treatments alike, the highest azoto-bacter abundance was found in
the treatment with no N added, while the lowest was recorded in the treatment with 200 kg N/ha added. The highest total
microbial abundance was obtained with 100 kg N/ha in inoculated treatments and 200 kg N/ha in uninoculated ones.

Abstract: The paper presents data on humus contents in 109 profiles of pseudogley soils in Kraljevo environs under three
different forms of land use: arable land, meadow and forest. Soil analysis showed that forest pseudogley soils had the
highest content of humus in the humus horizon, 5.99% on the average, while meadow soils followed with 3.37% and
arable land with the lowest average humus content of 3.31%. The high content of humus and a tendency of its increase in
forest pseudogley soils indicate deteriorating conditions regarding the mineralization of organic matter, which leads to
intensification of its accumulation in soil. Well aerated arable land was found to undergo more intensive mineralization
of organic matter and more intensive utilization, which decreases the content of humus. In the subhumus horizon, humus
content was considerably lower, 1.99% on the average in forest soils, 1.27% in arable land and 1.15% in meadow soils.
Humus contents were also found to vary considerably, their values in the humus horizon ranging from 2.85% to 9.68% in
forest soils, from 2.01 to 6.03% in meadow soils and from 2.02 to 4.63% in arable land soils. In the subhumus layer of
the profile, the most evident vatriation was registered in the arable land variant (0.44-4.01) of pseudogley (0.24-2.04).
This high variation of humus contents in the pseudogley soils examined, especially forest soils, indicate very different
amounts of organic residues as well as different conditions of their degradation, accumulation and humification

Abstract: In order to maintain the existing level of the soil fertility, nutrients taken out are necessary to be returned to the
soil by the yield. It is allowed to use all available sources in the course of returning of nutrients taken out. This paper
presents results gained on the effects of fertilisation methods on the yield of the maize hybrid ZP SC 704, then on the
dynamics of organic matter in the soil and the abundance of important systemic and physiological groups of
microorganisms that provide soil biogeny. The following fertilisers were applied in the maize crop: mineral fertilisers in
the rates of 332 and 664 kg ha-1, ploughed down stover, as an organic matter (each year in the amount of 8,000 kg ha -1),
combinations of mineral nitrogen and stover ploughed down, manure in the amount of two-three animal units per
hectare. It was determined that observed parameters (amount of organic matter, degree of organic matter transformation
into soil organic matter, the abundance of certain systemic and physiological groups of microorganisms), as well as, the
nitrogen content, were significantly increased in variants with ploughed down organic matter and mineral fertilisers.
According to obtained results it was determined that a long term application of mineral fertilisers did not significantly
affect the changes of the organic matter content in the soil nor it decreased the soil productivity. A long term application
of organic fertilisers in the form of stover and manure very significantly increased the content of organic mater and
elements of biogeny in the soil, whereby a positive effect of the combination of organic mater and mineral fertilisers was
particularly pronounced. Such a method of fertilising in the crop production undoubtedly satisfies the fundamental
principles of organic agriculture (organic food production with the ecological and economical effect).

been taken from two profiles on three depths 0-20 cm, 40-60 cm, and 80-100 cm which have been according to the extent
laboratory methodology for laboratories of soil biology. The results show that the enzymatic activity to these three depths
is very low in comparison with the enzymatic activity of areas degraded soil (molic eutricambosoil). The values of
dehydrogenase vary between 0.20 and 0.80 limits, the values of catalase vary between 10 and 85 and the saccharose
values vary between 0.15 and 0.35. We have to mention that we cannot make any kind of correlation between these
values and the soil sample depths. This thing can be explain through the heterogeneity of the dump material. Without a
selective uncovering, the vegetable layer frequently reaches in the depth.

zones prairiales. Les observations sont faites dans les années 2000- 2006 dans diverses stations avec une analyse de la
présence et de l`abondance de ces espèces. L’abondance des espèces dans les captures d`un endroit d`observation est
déterminée par rapport à la date de capture, par les conditions climatiques et par les caractéristiques offertes par
l`écosystème. L’analyse de ces trois facteurs pour un territoire donné en corrélation avec l`aire de répartition des
espèces permet d’expliquer l`absence des carabes dans un écosystème. Les endroits qui ont une diversité élevée

Abstract: Various studies pointed out the effect of NPK mineral supply on the biology of sunflower leaf apparatus: form,
structure, and activity of photosynthetic apparatus. Investigations have been conducted on five sunflower hybrids (P.I.
2001, Select, P.I. 2002, P.I. 2004, and Performer) with various degrees of precociousness, fertilized with different NPK
rates (N0P0K0; N60P80K60; N80P80K80), under pedoclimatic conditions of the Moldavian Plain. Leaf morphogenesis was
analysed by determining the number of active leaves and leaf area per plant, as well as the anatomical structure of leaf,
at limb and petiole level. The obtained results have demonstrated that leaf morphogenesis was differentiated according to
studied hybrid and dose of applied fertilizers. Analyses concerning the anatomical structure of leaf have shown
differences between experienced variants, which were found especially at the leading tissue and stomata apparatus. The
differences were quantitatively: number of collenchyme layers, number of stomata per area unit, number of leading
fascicles, and qualitatively: presence of concentric fascicles, presence of the cap of lignified cells in the phloem
parenchyma, and the presence of two stomata types.

Abstract: The study on the benthal fauna in Matita and Merhei lakes is based on a number of 172 qualitative and
quantitative samples collected in two stages (June and September) from different regions of the two lakes and from
different substrates; the processing of the biological samples permitted the identification of a number of 58 species from
18 supraspecific taxonomical groups: Hydrozoa, Spongia, Turbellaria, Nematoda, Nematomorpha, Polychaeta,
Oligochaeta, Hirudinea, Gastropoda, Bivalvia, Acarina, Ostracoda, Copepoda, Amphipoda, Cumacea, Mysidacea,
Isopoda and Insecta. The invertebrate associations are structured into two major communities: the community of
sedimentophile species and that of phytophile species. A relatively low number of species is cited as present in both
basins, especially among the sedimentophile ones. However, the phytophile fauna is abundant in Matita, which is
explained by the rich submersed vegetation.

Abstract: This study of the shallow water littoral zone from Vama Veche regards the vagile psammophile and
phytophile/iliophile fauna from the midlittoral stratum and superior infralittoral (0 – 2 meters deep) and it is based on 62
quantitative biological samples, taken in July and the first part of October 2005. Representatives from 15 supraspecific
taxonomical groups were identified: 44 species in the psammon and 32 species in habitats from the hard substrate with
vegetation; a relatively reduced number of species are encountered in both types of habitats, which is owed mostly to
their euritropism and capacity to move or to the fact that they are drawn by the water masses; however, most species
manifest an accentuated positive tropism for different types of habitat, such as certain species of psammic Turbellaria
and Polychaeta: Archilina endostyla, Monocelis lineata, Saccocirrus papillocercus, Namanereis pontica or the species of
phytophile crustaceans from the group of Harpacticida and Gammaridae Amphipoda or of Isopoda: Eurydice ponticapsammic, Sphaeroma pulchellum and S. serratum-iliophile, Idotea and Naesa bidentata phytophile. The coarse
midlittoral sediments are dominated by species of Turbellaria, Polychaeta, and Harpacticida. Representatives from 13
supraspecific taxonomical groups were encountered in these habitats; representatives from eight supraspecific groups
were identified in the mid-fine sediments from the sheltered zones of the infralittoral, the dominant ones being nematodes
and species of psammic copepods. A large number of species from 15 groups were identified in the habitats with macro
algal vegetation, the most frequent and abundant of them being the Peracarida crustaceans from the group of Isopoda
and Amphipoda.

carotenoid pigments in the marigold’s inflorescence represent a fundamental constituent of drugs. The paper examines
the dynamics of the pigment content in leaves and inflorescence in two marigold cultivars, the Comun and Bellezza del
Pacifico, with yellow and orange flowers, respectively. The pigment content was measured by spectrophotometry. The
results point out a maximum carotenoid pigment content with maximum light absorption in 425-426 nm and 447-447nm
in the orange flower cultivar (the Bellezza del Pacifico cultivar), which pleads for its introduction into cultivation.

Abstract. Economic success, i.e. obtaining profit on swine farms is influenced by managerial factors that ensure
performing standards of reproduction parameters in swine by diminishing service period and by achieving a calving
interval between 152-154 days. Obtaining from each sow 2.37-2.40 calvings per year over a longer period of exploitation
(6-7 calvings) contributes to the recovery of occasional expenses with the raising of breeding stock until the optimal age
for reproduction.
Key Words: swine, managerial factors, efficiency of reproduction, service period, calving interval.

Abstract. In the conditions of raising animals on farms with a high degree of artificiality and mechanisation, the
evolution of the puerperium influences the increase of the fecundity and birth rate percentage and results in an increase
of the duration of exploitation of sows. This evolution depends on the hypothalamus-hypophysis hormonal complex that,
during the first post-partum days, secretes gonadotropic hormones that trigger ovary activity. The earlier the ovary
activity, the earlier the uterus involution, degradation and eviction of secretions, and the morphological and functional
recovery of the endometrium are. Ovary activity in sows in puerperium is characterised by a substantial diminution of the
size of yellow gestation bodies during the first 7 post-partum days and the turning of the red colour in the first day into
dark brown and, towards the end, into mother-of-pearl white.
Key Words: sows, puerperium, ways of conducting puerperium

Abstract: Oat (Avena sativa L.) genotypes Chamois (drought tolerant) and Someşan (drought sensitive) were grown in
pots in greenhouse under controlled conditions and submitted to drought as follows: V 0- normally hydrated control
variant (0 S); V1- 5-day drought (5 S); V2- 10-day drought (10 S); V3 – rehydrated after 10-day drought (10 S – 5 R). The
observations and determinations were performed during the phenophases of vegetative mass development upon the
following physiological indices:- the osmotic potential of the second leaf (- bar, - the free proline quantity within the
foliar apparatus (mg/g.d.w.), - the quantity of chlorophyll pigments (mg./g.d.w.). All these determinations were carried
out upon the foliar apparatus belonging to young, mature and senescent leaves competition with the biosynthesis of the
chlorophyll pigments. The genotype Chamois (drought tolerant) has an increased capacity of proline biosynthesis in
competition with the biosynthesis of the chlorophyll pigments.
Key words: free proline, chlorophyll, osmotic potential, drought stress, oat

Abstract: In this paper are presented some researches concerning depth of the plantation of the roots horizontal of the
variety ”Centenar” plum tree, from the plantation created on the Experimental Station Banu Mărăcine. The researches
had been achieved in the autumn of the year 2006, at the variety Centenar plum tree, grafted on 4 rootstocks,
respectively: Oteşani 8, Pixy, Miroval and Roşior văratec, and the method of study it was used the profile method. We
found out that the maximum depth of the horizontal roots development is of 90 cm, the most roots we can found to the 3060 cm depth. As a result we suggest the depth of working in the orchard to be normal and the incorporation of the
organic fertilizers must be realized once with autumn ploughing.

Abstract: Phaseolus vulgaris has a great variability regarding the tolerance to saline stress, starting with values of 40-46
mM NaCl and up to 196-207 mM NaCl. The experimental results achieved made evident the existence of some bean
genotypes with a good tolerance to salinity during germination (Ohaba Forgaci I, Ohaba Forgaci II and Berini). These
genotypes have recorded during germination normal intensities of radicle growth and cotyledon development, and they
have synthesized important amounts of free proline with osmoprotector role. We have also determined the dynamics of
the dry matter percent during germination and within the post-germination phases. The increase of the dry matter
percent in the sensitive genotypes is due to their incapacity of hydration and water maintenance.

Abstract: The mains physiological indexes which were followed through the present research were: the leaf area at the
soya plants as well the determination of azote and phosphorus from the plant. In the conditions in which the plants are
treated with differentially nutritional solutions, it is observed that both in the transgenic plants case and in the
intransgenic one the leaf surface in higer at the variants with complete nutritional solution than with the solution without
azote or without phosphorus, and the quantity of azote, in plants increases in the same conditions. The phosphory from
the plants increases both at the plants treated with complete solution and incomplete thanks to the fact that the
phosphorus is easily accessible to the plants in the both conditions.

determine the water meadow vegetation to be discontinuous: on the steeper walls over the forest road, water meadow
species mix with lilac and flowering ash bushes, while upstream the beech and hornbeam woods go down to the river
banks. The vegetal cover contains thermophilous species also characteristic for other gorges in southern Banat.
Mediterranean, Balkan, and Pontic elements underline the link between the flora in this area and that of other regions

Abstract: Labour in agriculture may be analysed from the standpoints of economic structure of the population, its
household members' structure and employment structure. According to the 1991 and 2002 censuses agricultural labour
in Serbia has declined both absolutely and relatively. Based on the share of the agricultural in the total population
(10.9%), i.e. the active agricultural in the total active population (15.6%) Serbia has no shortage of agricultural labour.
On the other hand, both the age and education structure of agricultural labour are unfavourable raising the issue of selfreproduction. In addition, the number of household members especially individual farmers representing the key labour in
agriculture, has been significantly reduced.

Abstract. The purpose of this study is to help students in chemistry and in any other field related to chemistry
differentiate, better understand and use more properly the terms beginning with hydr(o)-, terms that can be misleading
because of their different referent (‘hydrogen’, ‘water’, and ‘hydrargyrum’). In our attempt, we have used the
lexicological approach. We have found out that there are about 84% combined words with hydr(o)- (‘hydrogen’) and
hydroxy(l)-. There were no limitations to this study. The practical implication of the study is that all these combined
words make up an exhaustive inventory which, if properly acquired by the students, can help them decipher more easily
the meaning of any specialised text in English.

Abstract. The purpose of the study is to show if there are any differences between the British English of tourism and the
New Zealand English from a globalising perspective. The study was carried out on a relatively small corpus of tourism
terms (91), which we analysed from a lexicographical point of view. The study shows that most of these terms are
acronyms, probably due to the speed people need to communicate nowadays. The study was limited by the fact that most
of the tourism terms analysed cannot be found in English Language dictionaries. The practical implications of the study
concern students in tourism economics: thus, they can get aware of the fact that though the English language spoken in
New Zealand may seem identical to that spoken in Great Britain, the English of tourism may be considerably different.
The originality of the paper consists in the fact that this is the first time such an inventory is being analysed in the

Abstract: The whole tourism industry, including agritourism, is growing rapidly worldwide. Slovakia, regarding its
geographic location in the centre of Europe, has extremely favourable conditions for rural tourism, especially for
agritourism. Beside the natural richness, such as mountains, caves, water areas, mineral waters, springs with healing
effects, rich fauna and flora, also historical buildings, held in relatively good state, and many live traditional crafts can
attract the modern tourists. Regarding all this, Slovakia is able to satisfy the needs of the most demanding our or foreign
tourists. The main objective of this work is to briefly present the natural beauties and cultural attractions in Slovakia, its
favourable conditions and development possibilities in the agritourism sector. Furthermore there are described the tasks
and activities of organizations responsible for agritourism and rural tourism (EUROGITES in Europe, SARTA in

Abstract: Limitation of resources and its rational utilization represents the main obstacles to development of households.
This paper emphasizes the luck of labour force and its unsatisfactory qualification structure, with which, under given
circumstances, managers have to achieve as good results as it is possible. To get closer to that goal, the labour force
managing process should start with labour force selection and evaluation of its work. The best results have been
achieved with combination of scientific methods, long – term personnel planning, objective evaluation of the work and
inclusion of the workers in evaluation process. The goal of all the methods is to identify the bed and the good sides of the

Abstract: Decision making about investment acceptance is always based on the intention of the investor to gain certain
income during the investment period. The integral analysis of economic effectiveness of investment is based on the
analysis of economic success, liquidity, and risk, as a three basic components of investment process. Unfavourable
financing conditions require from the owner of the household to make plans for lucrative businesses. This kind of
planning considers formulation of expectations in the future, especially the relations between inputs and outputs,
products prices and production costs. In crop production planning the rule of the highest revenue on limited resources
should be applied. Before formulating alternative plans in crop production, special attention should be paid to intensity
of soil usage. The selection of production lines depends on the most productive and the most lucrative crop system.

Abstract: With his undoubtedly restless and inquisitive creativity, in the first decade of the twentieth century, Anton
Strashimirov turned to the modern European drama, eagerly expecting the new century, and with it - the new man. He
created dramas full of symbolism, most of which remain only as marginal texts for the Bulgarian reader. In some of them
aspiration for interpretation of Biblical topics and motifs is revealed. A dialogue with the Bible can be traced in other
dramatic works of his, outside the context of symbolism. One of them is the romantic “Song of Songs” (1910).
Strashimirov is one of the Bulgarian authors, who chooses consciously, as an artist, and not sporadically, as a dilettante,
the creative realization of biblical and mythological constructs for the Bulgarian drama.

Abstract: Biological character of grape production influences the existence of numerous risks. Therefore, the research on
risk and uncertainty is one of the key problems of the investments into this kind of production. These risks are appearing
both during the vineyard establishment and during its exploitation and they are influenced by the state of soil, application
of agrotechnical and pomotechnical measures, diseases and pests appearance, the way of yields realization as well as the
market risks. Perception of risk is a precondition for business success and the higher profit realization. This is the reason
why risk management (identification, analysis and monitoring) should be a part of management policy. One of the
methods for the risk and uncertainty assessment in the case of the grape production investments is the sensitivity analysis
method. This method could show to investor how much the investment effectiveness indicators are sensitive onto the
possible changes of variable starting parameters (prices, production volume, expenditures, level of investments etc.), i.e.
this method enables constitution of the so-called certainty limits of particular starting parameters, which are considered
as critical ones in the investment effectiveness evaluation. By application of the sensitivity analysis method in the case of
two analyzed economic models of vineyard farms, it has been monitored development of the investment effectiveness
indicators in relation to the changes of starting parameters and there have been determined their certainty limits.

Abstract. Though medieval descriptions of Timişoara are scarce – the most consistent of all being that of the Ottoman
traveller Evlyia Celebi and of the Austrian traveller Henrik Ottendorf – the reconstitution of the epoch, i.e. of the features
of a medieval town and city, can only rely on extremely diverse information. The lack of documents that describe directly
and without any exaggeration aspects of life, corroborated with a very large number of indirect evidence can result in a
proper, edifying global image on the ground of an engraving and of a map of the streets of medieval Timişoara that are
unique in the historiography of this town. The general engraving of Timişoara, published in the revue Magazin istoric by
the Romanian Ioan Haţegan, confirms the information supplied by Henrik Ottendorf which, confronted with those
supplied by Evlyia Celebi and with the drawing made by the Austrian F. Watthay, coincide. In addition, it is confirmed
that in the middle Ages the name of the river flowing through the ditches of the city was the Timişul Mic. A problem that
could be confusing in Henrik Ottendorf’s description is that of the location of the Castle, which he locates south from the
city, not in the narrowest part of the fortification, but right in the middle of it.

name of the capital of the Banat area, Timişoara, is mentioned in the Chronicle by Asikpasazade in 1484, where it is
written that the Turks passed by Demeskar (the spelling ‘d’ is due to the Turkish pronunciation of the Hungarian name
“Temesvár” meaning ‘Timişoara’), went on and entered the Hungarian Country. After the Turks left the area, a vast
programme of colonisation of the Banat area with Italians and Spaniards original from Austrian-ruled provinces was
put into practice (1716-1740).

educational classes reach or not moral and civic objectives and if the topics are of particular interest to students, and if
the teacher uses means and methods that are active and formative. Synthesising drawbacks during educational classes,
we suggest both form masters and school managers to pay more attention to educational classes topics and issues. In
order to shape beliefs and features of character, teachers should start from this in their approach of students’ problems,
i.e. better know each student apart and direct and satisfy his/her wishes and aspirations. Among the features required
from a good form master are besides the features of a good teacher in general, the sympathy for the students, positive
traits of character (sincerity, communicativeness , etc.) and especially to be a good teacher that uses proper methods and
means to teach.

Abstract. The purpose of this study is to show in what measure language dictionaries can be of help in better
understanding GPS terminology. This study is part of a wider project of studying specialized languages belonging to
different agronomic subjects. The type of approach is lexicographical. The study of GPS terminology is at its beginnings,
as GPS technology itself has only recently emerged as scientific branch. The limits of the research are those caused by
the absence of linguistic tools specific to the field of GPS. The practical implications of the study are dictated by the
purpose of the study itself. The originality of the paper lies in the fact that this is the first time that someone approaches
the problem of the English of Precision agriculture in general and that of GPS technology in particular within the study
of ESP in Romania.
Key words: Precision Agriculture, teaching ESP, specialised terminology, GPS terminology.

Abstract: In this paper, we aim at identifying the methods of determining the models of the influence of variations of
some parameters on the “tourism process” and of its definition. The system in general can be described by proper
modelling. The necessity for developing such a system model in the case of solving an optimisation problem results from
the fact that its expression depends on the variables of the system. The generalised interpretation analysis of the tourism
process leads to the development of a generalised model of inputs-outputs for the determination of the functional links
existing between the different variables in order to establish functional dependence relationships. Applying the models,
even if generally, can result in considerable improvements in increasing performance, in deepening knowledge, and
understanding the ensemble in general.
Key words: input-output model, optimising, tourism

Résumé : L’avènement de la Communauté Européenne et l’enthousiasme qu’elle a semé sur son passage a eu pour
conséquence au niveau lexical la création massive de mots ayant pour préfixe euro - . En roumain ce préfixe est
relativement nouveau et se manifeste surtout dans la presse, souvent ayant une nuance péjorative. Dans ce travail nous
essayons de démontrer que, le plus souvent, ce préfixe est utilisé abusivement.

Abstract: In this paper, we studied the organization of private house holdings, the number of them, and the land that they
have. This land is very crumbed and difficult to work and need high resources that make them unprofitable. The cost per
hectare is high and the production that they obtain is small which causes great losses. But in this final years we observed
that most of house holdings are associated one with another in the purpose to buy seeds, fertilizer, pesticides and work
the field to obtain better crops, with high quality at a low costs.

Abstract: Ecological education is a form of education, which, through a system of specific activities, ensures the
moulding of ecological awareness. Moulding ecological awareness in school has two main components: a cognitive one
and an affective one. There have to be a good cooperation between topics in school so that each of them aids in moulding
ecological awareness in children. Bringing man to the verge of respecting nature and landscape values can be done
through instruction and education. Ecological education aims at guiding the student, i.e. the future citizen, to a more
objective point of view over reality (whose fundament is the relationship between man – men – environment), to enhance
him to participate, to become aware of the future, of the fact that the life of future generations and its quality largely
depend on his options. At present, it is necessary to study ecology at school, with a view to teach the young ones –
anybody else, in its debut stage –on why and how to protect nature. It is necessary that ecological education be an
important part of school education and instruction.
Key words: ecological education, ecological awareness, and ecological behaviour

Abstract: The functioning of an agricultural exploitation has, of course, finality. Each exploitation boss, enterpriser or
manager wants the exploitation results, and, implicitly, his/her results, successive to the exploitation administration, to
be as good as possible, like a reward for the material, human and managerial efforts exerted during a production cycle
or during a period of time, like an agricultural year.

Abstract: An important moment in the development of the technical-productive and social-economic informational system
has been played by accountancy methods. With the national bookkeeping, the human has managed to consolidate
categorically the economic decisional support, transferring the problem solving and decision making from the
probabilistic area into the certitude one. Bookkeeping represents a registration tool for stock movements, flow nature
and sense, having as objective the determination, during time, of the activity results, added value, benefit or loss, the
gross domestic product, national income, book debt and duty economy or balance account.

Abstract: The study presents the analysis of infidelity, its causes and effects on the marital relationship; we capture those
traits of personality that make a person become infidel. To do so, we take into account both the consequences of infidelity
and the feelings the hurt person experiences, such as uncertainty and confusion. The total number of the subjects of this
study is 80, of which 40 women and 40 men. The subjects we tested, aged 20-25 and 35-50, were selected taking into
account the way they got married; we only tested one partner of each couple. Thus, of the 40 women, 20 are aged 20-25,
while the other 20 are aged 35-50. The structure of the male sample was identical. There are, in the sample of men and
women aged 20-25, 10 people from undergraduate families attending the course, of the Agricultural and Veterinary
University of the Banat, Timişoara. After making a synthesis of the theoretical aspects, we can say that both men and
women tend to become infidel. The reasons for infidelity are: the tension within the couple, indifference, ignoring the
other’s wishes and desires, limiting to unpleasant talks detrimental to humorous ones, etc. Infidelity has always
important consequences – sometimes even capital ones – for the infidel himself or herself, for his/her partner, and for
his/her group. Such a situation shakes self-confidence and makes everybody ask himself or herself questions.

Abstract. The study aims at emphasising the necessity of knowing temperamental features of the human factor directly
involved in the educational process: student and teacher. Their use in the educational process results in an increase of
efficiency. The educational process is by excellence the result of the interaction between teacher and student, student and
student, etc. Both education and training depend on the existence of a positive inter-relationship, of an efficient
partnership. Though is relies on the nervous system features, and hereditarily determined, in biological terms temper is
considered a pheno-typical result; temper features have nothing to do with fatality, they can be changed through activity,
education, and self-education. In order to carry out the study, we used the temper typologies described in literature,
psychological questionnaires meant to determine the temper type, and psychological experiment. The research opens a
perspective on the size of the temper features impact on the educational process and on its efficiency. The results of this
study can be a theoretical aid for the teachers in practical activities with the students and, at the same time, a milestone
in self-regulation.
Key words: dynamic-energetic aspect, personality, education, and psychological knowledge
