Small grain variety tests are conducted each year to compare old established varieties with new varieties from other experiment stations, the United States Department of Agriculture, and from the South Dakota Agricultural Experiment Station. The data taken are summarized and used as a basis for recommendations. For the well-known varieties, five-year averages are reported. With the newer ones only one or two-year results, are given. It should be emphasized that an average of several years is superior to one-year's data. The plots were located at the Main Experiment Station, Brookings, and at the substations at Highmore, Eureka, and Cottonwood. The 1946 season was a season of extremes. Early spring precipitation was erratic, being a 1.17, .88 and .84 inches below normal for April at Brookings, Eureka and Cottonwood, respectively. This coupled with temperatures well above normal for April caused some uneasiness in the minds of those engaged in agricultural pursuits. In May the temperatures dropped well below normal. A hard freeze took place on the 11th and 12th of May, causing wide spread injury to stands of spring seeded small grains. Drought during May and the latter part of June retarded the recovery of small grain from the effects of the freezes. Oats were observed to head at Brookings while the plants were only eight inches high. At only one location were the experimental plots in good condition. At Highmore almost perfect stands were secured and a bumper yield was anticipated. Naturally the nursery at this location was totally destroyed by hail about the first of July.
