presc;s in detail the effects of fertilizers
on yields of wheat in 98 cooperative experiments on farms in many
parts of the Columbia Basin summer fallow wheat area of Oregon during 1953-54 and 1954-55. Effects on test weights and protein contents
are also discussed.
The purpose of the circular is to make the latest information on
fertilizer research available to county aents, farmers, the fertilizer
trade, and other interested persons and organizations. It does not give
fertilizer recommendations.
Some of the dataespecially the tables of yields on individual
farmsmay be used as the basis for fertilizer recommendations if the
soil and climatic conditions of a particular farm can be related to those of
one of the farms on which these experiments were conducted. Soil type,
soil depth, available moisture, and past management differ from farm
to farm and from area to area. Also, variations in climatic conditions from
year to year and from place to place make it impractical to base general
fertilizer recommendations on data from 2 years' work.
More work on the relationships between these variables and the
effects of fertilizers on wheat yields is in progress. It is hoped that these
studies will provide the basis for accurate fertilizer recommendations
for specific situations. In the meantime, the data presented should help
evaluate the benefits farmers may expect from fertilizers, and help
estimate the fertilizer needs of wheat in Columbia Basin counties and
similar areas.
The Research Program
In the fall of 1953, field research on the fertilizer
needs of wheat began in the summer fallow wheat area
of Umatilla, Morrow, Gilliarn, and Sherman Counties.
This research is expected to continue for at least 5 years.
Fertilizer experiments were completed on 49 farms
each year. These farms were distributed among the counties roughly in proportion to their wheat acreages. Within
each county, experiment sites were widely scattered, to
carry out the experiments under as many as possible of
management that prevails in Oregon's dryland wheat area.
Over the area, average annual rainfall varies from
about 10 to more than 20 inches. Soils vary from about
11 feet to many feet in depth, and from very fine sandy
loam to silty clay loam in texture. Altitudes range from
about 1,000 feet to about 3,000 feet. Combinations of differences in soil depth and texture, altitude, and precipitation result in many different conditions under which wheat
is grown.
the wide range of variations in climate, soil, elevation, and
Experimental Procedures
Each year there were 48 experiments on winter wheat
and 1 on spring wheat. With the exception of 4 experiments on lands of the Branch Experiment Stations at
Pendleton and Moro, all the experiments reported were
carried out in the fields of farmers who cooperated in the
research program. Farmers' names and communities in
which their farms were located are given in tables 3 to 16.
On each farm, 15 fertilizer treatments were repeated 4
times, on plots 8 feet wide and 50 feet long. The 60 plots
on each farm occupied about half an acre. Farmers who
were supplying fertilizers to their crop were careful to
apply none to the site selected for the experiment, but in
all other respects each farmer handled the experiment
site on his land in the same manner as the surrounding
field, up to harvest time.
Similar fertilizer treatments were employed on all
farms each year. Nitrogen was emphasized, but phosphorus and sulfur (and in 1954-55 the minor elements,
boron, copper, manganese, and zinc) were included. Nitro-
gen rates that were applied varied with estimates of the
average annual precipitation at the experiment site. On
farms in the lower rainfall areas (where it was estimated
that average annual precipitation was less than 18 inches),

the rates of nitrogen ranged, by 20-pound intervals, from
0 to 80 pounds per acre in 1953-54 and from 0 to 100
pounds in 1954-55. On farms in the higher rainfall areas
(where it was estimated that annual precipitation was
more than 18 inches) increases of 30 pounds and rates
from 0 to 120 and 0 to 150 pounds per acre were employed. These rates of nitrogen were applied to certain
plots in the fall, usually just before seeding, and to other
in the spring, usually in
March. Phosphorus, sulfur, and minor elements were
plots, previously untreated,
applied in the fall. All fertilizers were applied by means of
a belt-type applicator, slightly below or on the soil surface, in bands 12 inches apart. Ammonium nitrate, TVA
concentrated superphosphate, gypsum, borax, and the sulfates of copper, manganese, and zinc were fertilizer
sources.
At the time of fertilizer applications in fall and
spring, soil samples were taken from unfertilized plots,
by 1-foot increments of depth, to 6 feet or to rock. Laboratory analyses for available moisture and seveyal forms
of nitrogen were made. The data obtained from the soil
analyses have not yet been correlated with the yield responses to nitrogen fertilizers, and are not discussed in
this progress report.
At harvest, a portable self-propelled plot combine
was used to harvest a strip 40 inches wide and 40 feet
long from each plot. Yields were then calculated to the
acre basis. Test weight and protein content determinations
were made on samples of wheat from plots of all rates
of nitrogen, applied in fall or spring.

Effects of Nitrogen on Yields
The effects of nitrogen on wheat yields varied from
farm to farm, and were much greater than those of phosphorus, sulfur, or the minor elements. Average yields

given for each farm and each county in tables 3 through
16. Wide variations in yield responses on individual farms
show that nitrogen fertilizer recommendations for specific
farms within any county cannot be made on the basis of
the average yield response in that county. Recommendations can be made, on the basis of the data from individual
farms, if the soil and climatic conditions of any given farm
are similar to those of one or several of the farms (in

There seems to have been no important difference
in the responses of the different varieties of wheat to
fertilizers. Correlations of fertilizer responses with soil

types have not been made, but an examination of the data
40
of tables 3 through 16 (pages 11 to 24) indicates there
were large differences in the response obtained on farms
having the same soil type.* It appears that yield responses

to nitrogen fertilizer are related to soil type to approxiinately the same extent that available soil moisture arid
soil nitrogen are related to soil type.
An over-all summary of the yield responses of wheat
to nitrogen, for experiments in both the lower and higher
rainfall areas, is given in figure 1.

A greater number of favorable yield responses to
nitrogen were obtained in 1953-54 than in 1954-55. This
probably was due to differences in amounts of available
moisture. At the Crow pilot farm near Weston, the precipitation from September 1 through August 30 was 15.8
inches in 1953-54 and 12.4 inches in 1954-55. For the
same periods at Moro it was 12.2 and 8.5 inches.

Higher Rainfall Areas
The responses of wheat to nitrogen in the higher rainfall areas were widely different in 1953-54 and 1954-55.
In table 2, data on the effects of nitrogen on wheat yields
on 17 farms are summarized according to the class of
effects observed.
Of the 9 experiments in 1953-54, 5 were in Umatilla, 1 in Gilliam, and 2 in Wasco County. In 1954-55,
6 of the 8 experiments were in llJmatilla, 2 in Wasco
County. Spring wheat was grown in 1 LTmatilla County
experiment each year; winter wheat was the crop in all
other cases. In all experiments in Umatilla County, wheat
followed either peas or wheat grown the previous year;
wheat followed summer fallow in the other trials.
In 1953-54, yield increases were obtained from one
or more rates of nitrogen on all farms. These increases
are shown in figure 4. No yield decreases occurred.
In 1954-55, nitrogen responses in the higher rainfall
areas were much less favorable than the previous year.
Two of the eight experiments were in Wasco County,
on summer fallowed land. Significant yield increases from
nitrogen were obtained on both these farms. There were
no yield increases among the 6 experiments in Umatilla
County. In the higher rainfall area of this county, where
moisture is usually ample for annual cropping, the land
had been cropped with either peas or wheat the previous
year. Only small amounts of available moisture were in
the soil when the 1954-55 crop was seeded. The below-

normal rainfall of the winter and spring was insufficient
to refill the soil with moisture, resulting in low yields on
many farms in the area.
In 2 of the 6 experiments in Umatilla County the
effects of nitrogen were too small to be significant. On the
remaining 4 farms, yield decreases resulted from increasing nitrogen. Figures 5 and 6 show the increases and
decreases, compared to the yields on the check plots.
Comparison of Fall- and Spring-Applied Nitrogen
The effects of fall- and spring-applied nitrogen on
winter wheat yields were compared on 48 farms each
year. On some farms higher yields were obtained from
fall- than from spring-applied nitrogen. On other farms
the reverse was true. On over half the farms, differences
in the effects of fall and spring applications of nitrogen
were too small to be important. A summary of the over-all
effects of time of application is shown in figure 7.
Data presented in figures 2, 3, 4, 5, and 6 show that
both the beneficial and harmful effects of fall-applied nitro-
gen were, on the average, greater than those of nitrogen
applied in the spring. Fall nitrogen applications produced
yield increases on fewer farms than spring applications
(60 vs. 69 farms), but the yield increases from fall applications were larger on the average, especially in the lower
rainfall areas. Yield decreases from fall-applied nitrogen,
however, were greater in number and magnitude than
those from spring applications. (Visual observations in
early spring indicated that in some cases more stooling,
greater herbage production, and earlier exhaustion of soil
moisture resulted from fall than from spring nitrogen
applications.) All farms considered, differences in average
yields from fall- and spring-applied nitrogen were small.
Effect of Phosphorus, Sulfur, and Minor Elements
on Yields
Yield increases from phosphorus occurred on two
farms in 1953-54 and 5 farms in 1954-55. Soil tests show
similar values for sodium bicarbonate-soluble P in the soil
20
of these farms, and others on which no phosphorus responses were observed. They do not explain yield inIs
creases that were obtained.
In 1953-54, a significant yield response to sulfur was
obtained on 1 farm (Crow), on recropped spring wheat in
the higher rainfall area northeast of Pendleton. In 195455, sulfur produced a significant yield increase on winter
wheat in the higher rainfall area southwest of The Dalles
(Meeker). A yield decrease from sulfur on one farm in

1954-55 was indicated.
The minor elements boron, copper; manganese, and
zinc were applied together on all farms in 1954-55. There
was no evidence of a yield response to treatment with
minor elements.

Effect of Nitrogen on Test Weights
In 1953-54, fall-applied nitrogen significantly increased test weights on 31 farms, decreased them on 5
farms, and had no effect on 12 farms. Spring-applied
nitrogen increased test weights on 32 farms, decreased
them on 7 farms, but was without significant effect on
9 farms. Spring-applied nitrogen also has produced

mum yield" means the highest yield we can be reasotiably
sure of for a given farm. It was not necessarily the highest
yield recorded for that farm, but where yields appeared to
be higher, it was probably due to chance alone and not to
differences in nitrogen rates. No other yield exceeded the
on 16 farms. The reverse was true on 5 farms, and on
27 farms differences between fall- and spring-applied nitro-
gen were not significant. Comparison of yield and test
weight data reveals that, in general, increased nitrogen
increased test weights on farms where it also increased
yields. Decreases in test weights occurred only on farms

"least significant difference between means.")
As shown in figure 8, the protein contents associated
where increased nitrogen either decreased or had no effect
on yields. In general, test weights decreased with increases
in nitrogen only on fields having shallow soils and conse-
with "maximum yield" were nearly all within the desirable range.
quently low moisture supply. Of the 7 farms where decreased test weights resulted from increased nitrogen,
the soil was 2 feet deep on 3 farms, 2 feet deep on 2
farms, 2* feet deep on 1 farm, and 4 feet deep on 1 farm.
In the 2 years, rate of fall-applied nitrogen causing
"maximpm yield" resulted in more than 10 per cent protein content on 11 farms. On 6 of these, the highest yield
came from plots receiving no nitrogen. Added nitrogen
increased protein, depressed yields. For spring-applied
nitrogen, this was true on 6 out of 17 farms.
On the other farms, undesirably high protein contents
associated with "maximum yield" were exceptions to the
general rule.
Rates of nitrogen up to the rate giving "maximum
yield" increased yields faster than protein content. For
Effect of Nitrogen on Protein Content
With the exception of 1 farm each year, all the wheat
grown in the 98 experiments was of the soft white or
pastry type. For highest quality, the protein content of
the pastry wheats should not be much greater than 10 per
cent, nor much less than 8 per cent. In contrast, bread
higher rates, the protein content increased faster than
wheat quality is enhanced by increased protein content.
Objectionably high protein levels did not result from
increasing nitrogen until yield increases from nitrogen
had leveled off. This was true for both years. When more
nitrogen was applied than was needed to produce "maximum yields," protein content frequently rose to levels
higher than considered desirable by the trade. ("Maxi-

On many farms, the protein content of wheat grown
without nitrogen applications was undesirably lowless
than 6 per cent protein on 15 farms; less than 7 per cent
on 35 farms; and less than 8 per cent on 56 farms. Some
nitrogen was needed on these farms to raise the protein
content to the desirable range for baking quality.
