ABSTRACTS OF RESEARCH IN AGRONOMIC INVESTIGATIONS - 1955
THOMAS J. CONLON
ROTATION AND TILLAGE TRIALS - 1955
Yields in the 1955 Rotation and Tillage experiments followed rather closely the pattern of the 45-year average as reported in North Dakota Agricultural Experiment Station Bulletin 383.
In a new tillage trial comparing production on stubble land worked with the one-way disk, the double disk and the moldboard plow, production on the moldboard plowed land was 34% better than on double disked land and 20% better than on land worked with the one-way disk.
FERTILIZER TRIALS - 1955
A fertilizer trial to determine effects of phosphating small grain upon the moisture content of the soil profile was conducted in cooperation with the Soils Department, North Dakota Agricultural College.
In the new continuous commercial fertilizer trials begun on Series 8 of the Main Rotation Field this year wheat yields on cornland fertilized with 125 lbs. per acre of 16-20-0 were 6.2 bushels higher than yields from the unfertilized check plots. However, silage yields from corn plots fertilized at a rate of 100 lbs. per acre with 8-32-0 commercial fertilizer applied in the drill row were no better than silage yields from unfertilized plots.
ROUGHAGE TRIAL - 1955
This year yields from the sorghum and sudan grass varieties were particularly disappointing, none producing enough to be considered worth harvesting. The best yielding crop in 1955 as in previous years is corn. The adapted hybrids and open pollinated varieties have consistently produced satisfactorily high yields. For quantity production of good quality feed corn is the best silage crop for this southwestern North Dakota area.
BARLEY TRIALS - 1955
Barley yields were excellent in this area this year, being higher than for any year in the past decade except 1948. The five top yielders in the 1955 variety trial were: Husky, Kindred x Titan (B103), Tregal, Titan and Hannchen.
Dekap, a newly introduced variety from Transcaucasia, was top yielder in the Uniform Great Plains Barley Nursery at Dickinson this year, averaging nearly 10.0 bushels per acre more than the second highest yielding entry, a Trebix x Spartan cross CI 10003.
CORN TRIALS - 1955
Yields in the 1955 corn trials at Dickinson were poor because of droughty July and August growing weather. Average silage yields in the corn silage production trial ranged from about four to six tons per acre.
Yields were poor and variations between treatments were rather wide in the rate of planting trial with corn. From two years results it would seem that the 12 to 18 inch spacing in the drill row would be the most satisfactory. planting rate of four of the rates under test.
FLAX TRIALS - 1955
Yields were fairly good in this years Flax Varietal Trial with Dakota, Linda, Marine and Bison all yielding seven bushels or more per acre. Dry weather in July reduced the potential flax yield and was favorable for weed growth which also aided in reducing the final crop yield. Yields in the weed free nursery trials were more than double those from the field plot trials.
OAT TRIALS - 1955
Yields in this years' oat variety trial at Dickinson were higher than for any year since 1948. Highest yielding variety was Gopher which averaged 78.8 bushels per acre followed by Branch at 77.8 bushels per acre. Lowest yield was from Andrew with an average of 57.4 bushels per acre.
Some oat stem rust was present again this year and depressed yields some, especially the yields of Palomino and Clarion, the two varieties that carried the heaviest infection.
WINTER RYE TRIALS - 1955
High yields were recorded for the winter rye varieties in this years' trial, with Emerald, Dakold and Caribou making up the top yielding group, followed by the White Soviet and Pierre. The poorest yielding variety in the trial has been Tetra Petkus, producing only about half as much as the varieties in the high yielding group this year.
WINTER WHEAT TRIALS - 1955
A summary of thirty years of trials with winter wheat at the Dickinson Experiment Station was published in Vol. XVIII No. 1 of the North Dakota Agricultural Experiment Station Bimonthly Bulletin, the September-October issue for 1955.
Three separate trials with winter wheat were seeded at Dickinson in 1955. Winterkilling was heavy, averaging virtually 100% in all three trials.
HARD SPRING WHEAT TRIALS - 1955
Stem rust was not a serious problem in southwestern North Dakota in 1955, and this fact plus favorable planting weather in April and ample rainfall in June combined to produce excellent wheat yields. N.D. 8, N. D. 25 and N.D. 3 were high yielders in the variety trial with respective averages of 33.4, 30.6 and 28.9 bushels per acre. Lee, Selkirk and Mida all averaged approximately 28.5 bushels per acre.
Promising new material in the nursery trials includes: strains from the cross between Thatcher and Kenya Farmer and four strains in the Dickinson Station F - 5 nursery which produced over 35.0 bushels per acre.
