REPORT OF AGRONOMIC INVESTIGATIONS - 1961
BY THOMAS J. CONLON

THE SEASON OF 1961

The season of 1961 was characterized by below average precipitation and above average temperatures in May, June, July and August.

Above average precipitation in September of 3.05 inches raised the total annual precipitation figure to 13.90 inches which was still 1.60 inches below average for the year. The September precipitation was too late for any crop except pasture in 1961 but provided excellent conditions for fall seeding of winter grains.

Daily precipitation figures for 1961 are given in Table 1.

Table 2 summarizes the important climatic data.

CROP ROTATION AND TILLAGE STUDIES AT DICKINSON

In southwestern North Dakota, the tillage method and cropping history of the land during the previous year have a most important effect on crop production. Crop yields in this area are dependent upon the moisture provided by seasonal rainfall plus the moisture which is stored in the soil at seeding time, and any farming practice that will aid in holding and storing moisture in the soil, and which will make maximum use of that moisture for crop production is recommended practice for this area.

In recent years the recognition of the importance of the use of commercial fertilizer on some crops has resulted in the inclusion of several trial designed to study the effects of commercial fertilizer on crop production when used along with different crop rotation and tillage methods.

In these experiments, tillage in preparation for seeding usually is begun within two or three days of the earliest work on farms in the community. The average seeding date is about the middle of April. Average harvest time is the first week in August.

Grain yields in these experiments are no better than yields harvested on the better farms in the area, and for the most part reflect fairly well the annual yields for this area.

USE OF COMMERCIAL FERTILIZER IN A TWO-YEAR
CORN-WHEAT ROTATION

In 1955 a series of two-year corn-wheat rotations were planned to determine the effects of commercial fertilizer application on crop yields in such a rotation, and also, to determine the residual accumulation, if any of commercial fertilizer applied to the land annually. Soil tests made in 1955 indicated a need for drill application of 75 pounds of ammonium phosphate (11-48-0) on the wheat and 100 pounds of ammonium phosphate (8-32-0) on the corn in these trials.

In these trials fertilizer was applied to the wheat with a conventional fertilizer attachment to the grain drill. The first two years of the trial, 1955 and 1956, fertilizer was applied to the corn crop with a split boot applicator. In 1957, 1958, and 1959, an applicator which placed the fertilizer about two inches to the side and at the same level as the seed was used. The important point regarding both of these methods of fertilizing corn is that the fertilizer was placed at the same level or above the seed but neither device placed it below seed level. In 1960 we began work with a fertilizer attachment which places the fertilizer two inches to one side and two inches below the seed level.

Tables 4 and 5 give the 1961 yields from this trial. Tales 6 and 7 summarize results from this trial for the past seven years.

COMPARISON OF WHEAT YIELDS ON CONTINUOUS CROPPING,
CORNLAND AND FALLOW, FERTILIZED AND UNFERTILIZED

This trial was begun in 1959 to compare long time results from commercial fertilizer application on three different cropping systems.

The fertilizer requirements, determined by means of a soil test are: 25 pounds N and 36 pounds of P2O5 per acre on non-fallow land and 8 pounds N and 36 pounds P2O5 per acre on fallow land.

Yields in this trial for the three year period 1959 through 1961 are summarized in Table 9.

WHEAT-SORGHUM, WHEAT-CORN AND WHEAT-SUDAN
COMPARED IN TWO-YEAR ROTATION

Sorghum, sudan grass and corn are compared as silage crops in this trial. Grain sorghum is also included, and is harvested as silage and for grain in years when grain matures.

In 1960 the varieties planted were Reliance grain sorghum, Ranches forage sorghum, Piper sudan grass and Nodakhybrid 301 corn. In 1961 the same varieties were used except for the substitution of MS323 grain sorghum instead of Reliance.

Yields for 1960 and 1961 are given in Tables 10 and 11.

In a separate trial sorghum was seeded on July 5 on land that had earlier been seeded to sudan grass but which was considered to be a failure. This late seeding was also a failure, with only a very short growth resulting from this late seeding. The use of sorghum and sudan for late seeding is often promoted as an emergency crop to provide feed after failures have resulted from spring and early summer drought. These seedings are successful only if precipitation is adequate germination and growth during July. During this period rainfall in this area usually comes in the form of showers.

SORGHUM ALMUM

This crop was included in the Dickinson trials for the first time in 1960. The trial includes seedings in cultivated rows and in solid drilled planting with a conventional 6 x 14 press drill.

The solid drilled planting was a total failure in both 1960 and 1961. Yields from the planting in cultivated rows are given in Table 12.

We experience the same difficulty in growing sorghum almum that we have in growing sorghum and sudan grass.

YIELDS ON CONTINUOUSLY CROPPED LAND COMPARED
WITH YIELDS FROM ALTERNATE CROP AND FALLOW

The Continuously cropped series of plots set up in 1908 have been continued without interruption for fifty-five years. Yields from this year's trial and average yields for the fifty-five year period, 1908-1961, are summarized in Table 14.

This experiment has shown spring plowing to be a better tillage method for this area than fall plowing. When spring plowing is practiced, the grain stubble is left standing during the winter months to catch and hold snow which helps provide moisture for germination and early growth of the crop in the spring. This is perhaps one of the biggest reasons for differences in production from these two tillage methods.

Local spots of gumbo or heavy clay soil and small areas of river bottom land that dry out slowly in the spring are the exceptions that may require fall plowing in western North Dakota.

At the present time, continuous cropping of small grain is neither recommended or practiced to any extent in this area. Alternate cropping and fallow is a common practice over much of the region, but in the past few years this practice has been replaced by many farmers with a corn-grain rotation which is a more productive cropping sequence if the corn crop is utilized as silage.

SPRING MOISTURE AND YIELDS ON STANDING STUBBLE VS. SPRING
MOISTURE AND YIELDS ON STUBBLE LAND TILLED IN THE FALL

Crops in western North Dakota depend upon the moisture provided by seasonal rainfall plus the moisture stored in the soil at seeding time. It is important that we use only those tillage practices that will conserve soil moisture.

Fall tillage of stubble land is not an uncommon practice in western North Dakota. Except for minor localized spots of heavy clay and gumbo soils, fall tillage probably is unnecessary. In fact, in some years fall tillage may be detrimental to yields of small grain the following season.

This trial, begun in the fall of 1957, compares soil moisture at seeding time and yields of wheat stubble land: Where the stubble is not tilled in the fall, where the stubble is tilled with the one-way disk in the fall, and, where the stubble is tilled with wide sweeps in the fall.

Data from this trial for 1958 and 1959 crop seasons show no significant differences among these three treatments at the 5 per cent level of significance for soil moisture to a depth of 36 inches at seeding time or for yield of wheat for either year. In 1960, however, there was a significant difference of 4.5 bushels of wheat per acre in favor of standing stubble compared with one-way disked stubble and 3.3 bushels of wheat per acre in favor of standing stubble compared with stubble tilled in the fall with wide sweeps. In 1961, the difference in yield was 6.3 bushels per acre more on standing stubble compared with one-way disked stubble and 1.9 bushels per acre more on standing stubble when compared with yields on stubble tilled in the fall with wide sweeps.

Yields from this trial for 1960-61 are given in Table 16. Moisture determinations are summarized in Table 17.

EXPERIMENTS WITH BARLEY - 1961

Experiments with barley in 1961 included the varietal field plot trials, the Great Plains nursery planting and a special nursery of material furnished by Dr. Glenn S. Peterson, North Dakota State University.

FIELD PLOT TRIALS

Betzes, highest yielding variety in this year's trial produced only 16.3 bushels per acre on fertilized summer fallow. These are the lowest barley yields recorded from this trial since 1949.

Data from the field plot trials are summarized in Tables 21 and 22.

NURSERY TRIALS

Results from the 1961 Great Plains nursery planting are given in Table 23.

Material grown in the special nursery for Dr. Peterson was harvested and forwarded to him.

EXPERIMENTS WITH FLAX - 1961

Experiments with flax at the Dickinson Experiment Station in 1961 included a varietal field plot trial of six varieties seeded on summerfallow on May 8, and the Uniform early-sown flax nursery which was planted on April 20.

FIELD PLOT TRIALS

This year's flax variety trial was a total failure because of the drought.

Yields from the flax variety trial for the past ten years are given in Table 24.

NURSERY TRIALS

Very poor yields were harvested from the nursery planting this year because of the drought. The earlier seeding date of April 20 did not seem to make a difference in this year's production.

Yields from this year's flax nursery planting are given in Table 25.

EXPERIMENTS WITH OATS - 1961

Experiments with oats at the Dickinson Experiment Station in 1961 included a field plot trial of 12 varieties, the North Central States Uniform Oat nursery planting and a special planting of 1958 Aberdeen selections.

FIELD PLOT TRIALS

Yields in the 1961 oat variety trial were the poorest harvested at the Dickinson Station since 1941 when yields of oats were reduced by a severe hail storm. Yields this year rank with the poor oat years of 1931, 1933, 1934, 1936 and 1937.

Data from the oat variety trials are summarized in Tables 26 and 27.

NURSERY TRIALS

Yields in the 1961 nursery plantings were the poorest recorded for many years because of the drought.

Data from this year's nursery plantings are given in Tables 28 and 29.

EXPERIMENTS WITH WINTER RYE - 1961

Fairly good yields of winter rye were harvested in 1961 considering the droughty growing conditions. Elk was the poorest winter survivor and was disappointing in this respect.

Data on the winter rye variety trial are given in Tables 30 and 31.

EXPERIMENTS WITH SAFFLOWER - 1961

Highest yield in this year's regional safflower planting at Dickinson was 3.0 bushels per acre.

Safflower is not a particularly good crop under droughty growing conditions and yields were poor this year for this reason.

Data on this year's safflower trial are given in Tables 32 and 33.

Iodine and oil percentage determinations were made by John E. Bear, USDA.

EXPERIMENTS WITH WINTER WHEAT - 1961

The Hard Red Winter Wheat Regional Performance Nursery was seeded September 20, 1960 on summerfallow and emergence and fall growth was fairly good. Spring survival was zero for all entries.

Table 34 lists entries in this year's planting.

Minter winter wheat planted with the winter rye in field plot trials was considered a total failure this spring.

Work with winter wheat is being expanded at this Station to include seedings made with hoe or furrow-type drills on both fallow and stubble land.

EXPERIMENTS WITH SPRI NG WHEAT - 1961

Experiments with spring wheat in 1961 included field plot trials of 14 varieties of hard red spring and six varieties of durum wheat, the Uniform Regional Nursery, the Uniform Bunt Nursery, and nurseries of material produced at Dickinson. Most of this material is early generation material for purposes of selection and yield data were not recorded on this material this year.

Yields and other agronomic data recorded from the 1961 trials with wheat are given in Table 35 through 40.

In addition to the field plot and nursery trials, this year the Dickinson Station cooperated in growing 12 bushel lots of four varieties and smaller lots of two other varieties for the Crop Quality Council milling and baking quality tests.
