BAU – SABOR, BHAGALPUR
Experiment 1: Effect of tillage, establishment methods, crop residue addition and
bio-priming on sustainability and productivity of rice-lentil cropping system for
rainfed drought-prone areas.
Rice - lentil is a prominent cropping system of Bihar under rainfed agriculture or water
scarce condition. Shortage of irrigation water and labour during peak periods make
transplanting and manual weeding costly, invariably causing delays in farm operations.
Moreover, puddling as a prerequisite for rice transplanting deteriorates the physical
properties of soil. Puddling forms a compacted layer (plough pan) that restricts
percolation of water causing waterlogging and resists root penetration and growth of
the following crops such as lentils in rainfed systems where land preparation is done
quickly to restrict evaporation of soil moisture. Land preparation becomes difficult and
requires more energy to achieve proper soil tilth for sowing of succeeding crops in dry
season. To solve this problem, rice seedlings may be planted after rainfall without
puddling at saturation level of soil on clean field which can save the soil from harmful
effect of puddling on succeeding dry season crop. Similarly, now-a-days, conservation
agriculture (CA) practices like zero tillage, residue incorporation, and bio-priming are
becoming popular as they help to save labour, energy and time without sacrificing on
overall system productivity. These practices maintain the soil tilth and the next crop
after rice gets more time to grow as sowing is possible at optimum dates. Therefore, on
the basis of above facts an experiment has been planned on establishment methods of
rice and their effect on lentil under rice-lentil cropping system in rainfed condition.

Experiment- 2 Effect of chemical weed management on growth, yield and weed
dynamics in lentil
Weeds infestation causes 30-40 % losses in dry season crops. In pulses, crop losses due
to weeds ranging from 60-70 percent at farmer’s field are common and deteriorate the
quality of the produce coupled with poor resource use efficiency (2009-2010 Annual
Report of AICRP on Weed Control, RAU, Pusa). This problem gets more intensified
due to increasing problem of immense labour shortage during peak periods. Lentil is
short stature crop and slow growth at initial stage favours heavy weed infestation.
Under given circumstances farmers need alternate production system using chemical
weed management that is more efficient, less labour-intensive and shows quick
response enabling farmers produce more at less costs. Thus, chemical weed control is
major prerequisite for improved lentil productivity and production using new molecules
of herbicide.

Experiment -3. Evaluating different cropping patterns and tillage methods in
rainfed drought-prone situation
With the availability of new short duration drought tolerant rice varieties like Sahbhagi
dhan and popularization of zero tillage practices it has become possible to plant various
pulses and oilseeds crops either solo or mixed and low water requiring cereals like
barley in time during last week of October or in early November under rainfed
situation. Zero-tillage reduces the time for land preparation and planting, and saves
fuel, water and labour costs in both timely planting and late planting. It also improves
the efficiency of fertilizer, and reduces wear and tear on the tractor. This experiment
has been planned to test various low water requiring crops after short duration rice
variety Sahbhagi dhan using zero tillage and convention tillage soil configuration
options for rainfed drought-prone areas.

Experiment 1: Comparative evaluation of wheat varieties and establishment
methods under submergence- prone rainfed lowland ecosystem
In recent years emphasis is shifting towards submergence- prone rainfed lowland
ecology which offers a great potential in enhancing productivity and production of ricewheat cropping system. During recent years, the International Rice Research Institute
has made considerable progress in developing rice varieties with increased tolerance to
submergence stresses. These tolerant varieties reduce farmers’ risk and stabilize rice
productivity. They mature early when submerged. Similarly, many new high yielding
wheat varieties have been recently released by national systems that can fill well into
the location specific requirements of rice-wheat system. There is a great need to
introduce these new varieties to enhance the production of flood-prone ecosystem of
Bihar.
There is no doubt in the fact that farmers can substantially increase the rice-wheat
system productivity by using best management practices developed by research
institutions for these varieties. There are enough Bihar specific evidences that
cultivation of rice through system of rice intensification (SRI) can increase grain yield
by two folds as compared to current yield levels. Similar claims are being made for
system of wheat intensification (SWI) also and Bihar govt is putting lot of emphasis on
it by offering huge subsidies on it. However, this SWI method of wheat has not yet
been tested and documented properly by research institution and universities. In this
context, this study has been planned to evaluate the performance of wheat varieties
grown using BMP and SRI methods in terms of its grain productivity.
The main components of System of Wheat Intensification (SWI) production
techniques are as follows:
a. Seed Treatment: Materials required for seed treatment

25 kg seed /ha (as per recommendation)

50 lt water (heated up to 600C)

Vermi-compost @ 12.5 kg

Gud (Jaggery) 10 kg

Cow urine 10 lt

Bavistin
Add seed to water (heated up to 600C). Collect and discard the seed floating on water
surface. Mix vermin-compost, gud & cow urine and leave it for 8 hrs. After filtering it
with cotton cloth, add Bavistin 2g per kg seed (as per BMP recommendation for wheat
production) and leave it for 12 hrs.
b. Seed rate: In this production system, the requirement of seed is very less as compare
to general production system i.e. 25 kg seed/ha only.
c. Time of sowing: It is same as in common wheat production and it may vary for
variety
d. Spacing: Row to row and plant to plant is 20 cm.
e. Depth of sowing: 2-3 cm is recommended and in any case it should not be more than
5 cm depth of soil.
f. Method of sowing: It should be sown in line 20 cm apart.
g. Manures and fertilizers:
i. With last ploughing- Apply vermi-compost 10 q/ha or FYM-50 q/ha, DAP-67.5 kg/ha
and MOP-34 kg/ha and mix well with the soil.
ii. After first irrigation- Mix 100 kg urea with 10 q of vermi-compost and broadcast.
iii. After third irrigation- 37.5 kg urea and 32.5 kg MOP should be applied.
h. Irrigation:
i. After 15 days of sowing first irrigation must be given because after that emergence of
new root starts and if there is moisture stress then drying of roots may occur.
ii. Second irrigation should be given at 25 days after sowing
iii. Third irrigation should be given after 35-40 days of sowing
iv. Next irrigations on 60, 80 and 100 days after sowing may be applied as per
requirement of crop if needed.
i. Weed management:
i. Weeder or Small/narrow spade after 2-3 days of first irrigation applied
ii. Weeder or Small/narrow spade after 2-3 days of second irrigation applied
iii. Weeder or Small/narrow spade after 2-3 days of third irrigation applied

Experiment 2: Evaluating the performance of timely and late sown varieties of
different dry season crops grown using zero tillage and conventional tillage
methods
Rice followed by wheat/gram/rye or mustard are prominent cropping patterns being
followed in submergence-prone areas of Bihar. Timely crop establishment has great
role for improving and stabilizing yield of these dry season crops. The time available
after rice season is a limitation under submergence-prone ecosystems because most of
the rice varieties are medium to late maturing. Different varieties of these dry season
crops are available now for timely and late sown conditions that can fit well in the
system. One of the major advantages of ZT over CT during dry season is that it
facilitates 7-10 days early seeding besides reducing cost of cultivation and providing
better scope for utilization of underutilized /unutilized or rice-fallow lands thereby
enhancing overall system sustainability and profitability. Keeping these facts in mind,
this experiment has been planned to test improved normal and late sown varieties of
these dry season crops grown using ZT and CT methods.

Experiment 3: Effect of chemical weed management on growth, yield and weed
dynamics in Rye and Gram.
Weeds are menace for any crop in general and oilseeds or pulses in particular. Very few
herbicides recommendations for gram and rye are found really effective under actual
field conditions. At present only Pendimethalin is popular among farmers to control
weeds of these two crops, though it too has with many limitations. It is a pre-emergence
herbicide and has been found very effective for controlling the broad spectrum weeds
but only up to 15-20 days after sowing. New weeds emerging after this period inflict
heavy losses to grain yield and quality of these crops. Of late, a gradual shift in weed
flora due to climate change is also being increasing noticed in submergence-prone areas
of Bihar. Hence, it is required to test and recommend the doses and schedule of new
herbicides for gram and rye specifically for rainfed lowland ares of Bihar. In this
context, this experiment was laid out to test the potential of available new herbicides
and to recommend suitable herbicide schedule to control post-emergent weeds in gram
and rye crops.

Experiment- 4. Evaluating the performance of bio-agents against lentil diseases
Different microbes are reported to improve plant health and to suppress root rot and

also reported to promote the plant growth therefore their effect would be also evaluated
on their ability to increase the tolerance to drought and ultimately on plant yield.

Experiment 1: Varietal evaluation of lentil grown using zero tillage and
conventional tillage methods following puddled and un-puddled transplanted rice.
Puddling as a prerequisite for rice transplanting deteriorates the physical properties of
soil. Land preparation becomes difficult and requires more energy to achieve proper
soil tilth for sowing of succeeding crops in dry season and it may cause some negative
impact also on succeeding dry season crops, especially on pulses which require a good
root growth for better nitrogen fixation. As an alternative practise, rice seedlings can be
planted after rainfall without puddling at saturation level of soil on clean field which
save the soil from harmful effect of puddling and encourages good growth of
succeeding dry season crop. Keeping the above facts in mind, one experiment was
started during Kharif 2012 to test rice genotypes using puddled and unpuddled
establishment methods. It was planned to test the overall effect of puddled and
unpuddled rice on the productivity of succeeding lentil crop.
In rice-lentil system, early crop establishment has great role for improving and
stabilizing yield of lentil. Farmers normally go for surface seeding of lentil to avoid
delay in planting and to harness maximum benefits of residual soil moisture. However,
the same benefits can be achieved through use of conservation agriculture option of
zero tillage (ZT) with significantly enhanced grain harvest of lentil over what is
achievable through surface seeding. ZT reduces the cost of cultivation by
approximately Rs 2,500-3,000/ha, facilitates early seeding (7-10 days), provides better
scope for utilization of underutilized /unutilized or rice-fallow lands and enhances
system sustainability and profitability. In contrast, conventional system increases the
cost of cultivation, delay the planting, reduces the yield and responsible for less
utilization of underutilized/ fallow lands. Therefore in this experiment we will test the
effect of zero tillage and conventional tillage on various varieties of lentil and the
overall effect of puddled and unpuddled rice on the productivity of succeeding lentil
crop.

KVK, Aurangabad
The average grain yield of lentil and chickpea under rainfed agriculture or water scarce
condition in Bihar is very low compared with potential yield. Many factors are
responsible for this low productivity including shortage of supplementary irrigation
water, improper nutrient management, use of traditional varieties, improper plant
protection major etc. The time availability for sowing lentil and chickpea depends on
the wet season crop. With the introduction of high yielding short duration drought
tolerant verities of rice in wet season, it seems worthwhile now to look for the suitable
dry season varieties of lentil and chickpea that fit well in cropping pattern of the area.
Therefore on the basis of above facts these on-farm trials have been planned for varietal
evaluation of lentil and chickpea. Moreover, a separate on-farm trial to judge area
specific major nutrient elements requirement for lentil has been commenced using
nutrient omission concept. The result will give an idea what are the major nutrients
needed by lentil for better system productivity and may be used as a base data for
nutrient manager in future.

Wheat is an important dry season crop in Bihar but its’ planting is always a trying
situation. Its production is always uncertain under rainfed lowland as the preceding rice
crop influences the timely sowing of wheat. Some good rice varieties are late maturing
hence time for wheat sowing is restricted. The farmers who grow sugarcane face the
same situation for wheat planting. It is worthwhile to find the most suitable new wheat
varieties that fit well into the location specific climatic conditions. Hence, a varietal
trial with different wheat varieties has been planned.
In addition a separate nutrient omission trial to test area specific need of wheat for
major nutrient elements has also commenced. This will give an idea what are the major
nutrients needed by wheat and the data generated may be used for nutrient manager in
future.

KVK- Sitamarhi -Pupri
Lentil is an important legume crop in Bihar. The average grain yield of lentil in Bihar is
very low compared with potential yield. Many factors are responsible for low
productivity including the improper nutrient management, use of traditional varieties,
improper plant protection, etc. Sowing time of lentil depends on the duration of rice
variety. With the introduction of new stress tolerant rice varieties like Swarna-Sub1in
wet season, it has become necessary to test new varieties of lentil that can adjust well in
cropping pattern of the area. Therefore some on-farm trials have been planned to
evaluate varieties. Moreover, the major nutrient elements requirement for lentil is being
judged separately through nutrient omission trials.
On-farm trial 1: Varietal evaluation of Lentil
Variety: 5
T 1: Arun
T 2: PL- 639
T3: IPL- 406
T4: K- 75
T5: Deshi Lentil (Local Check)
Replications: 5 (2 at KVK and 3 at farmers’ field)
Experimental Design: RCBD
Observations:

Plant height at every 30 days

Number of branches in 1 m2 (average of 4-5 samples of 1 m2 from the plot)

Number of pods in 1 m2 (average of 4-5 samples of 1 m2 from the plot)

Nodulation-No of nodules/plant

Number of grains in 1 m2 (average of 4-5 samples of 1 m2 from the plot)

Yield of grain in each plot (q/h)

Report insect/pest and diseases

B/C (yield at demonstration plot/yield at farmers plot)
On-farm trial 2: Response of lentil to different doses of major nutrients
Lentil is major pluse crop in Sitamarhi district, however it productivity is still very low.
Most of the farmers are cultivating this crop with without using fertilizers. The various
research reports have indicated that use of P @ 40-60 kg/ha is very effective.
Application of K at around 20kg/ha is also found beneficial in sandy or eroded soil.
Sulphur is unlikely to be deficient if fertilizers containing S impurities are applied to
other crops in the rotation. We have planned this on-farm trial using NPK&S as
appropriate combination as treatments.
Treatments:5
Full dose of NPK and S is 20, 40, 40 and 20 Kg/ha
T1
: NPK & S (full dose)
T2
: PK & S (full dose)
T3
