EXPERIMENTS WITH WINTER WHEAT - 1965

Experiments with winter wheat at the Dickinson Experiment Station in 1965 included the Hard Red Winter Wheat Regional Performance Nursery, the intrastate Winter Wheat trial and a trial comparing a hoe drill seeding at a spacing of 10 inches with a hoe drill seeding at a spacing of 20 inches.

Northern Regional Performance Nursery: The regional nursery trial is grown at Dickinson mainly as a test of winterhardiness for newly developed strains of winter wheat. In years when satisfactory survival is obtained the test is continued through harvest for an evaluation of comparative yield, disease reaction and other agronomic characteristics under western North Dakota conditions. This years' planting of the regional nursery included the entries shown in table 24. None survived to spring.

Intrastate Winter Wheat Survival and Production Trial: This trial has as its objective the comparison of the furrow drill and the double disk drill for seeding winter wheat. It was begun in the fall of 1961, and is grown at several other branch stations.

All winter wheat in the 1965 planting at Dickinson, except the hoe drill plantings on stubble land, winterkilled completely. Yield data and other agronomic data from the 1965 planting at Dickinson are recorded in table 25.

The Effect of Improved Cultural Practices on Winter Wheat Survival and Yield in Western North Dakota: This trial was begun in the fall of 1964 to compare survival and yield data of winter wheat planted with the furrow drill at a row spacing of 10 inches and at a row of 20 inches. Plantings at both spacings were made on summerfallow and on stubble land. Survival of all winter wheat seeded on summerfallow in this trial was zero. Survival of winter wheat seeded on stubble land was equal for both drill spacings and was recorded as 50%. Spot overseeding with spring wheat was necessary on both spacings.

Yields from this trial are summarized in table 26.
