Six weeks of favorable weather in June and early July made possible the remarkable small grain crop of 1958. This period was sandwiched between an early spring drought and a midsummer drought, and favored crops and crop varieties with moisture needs matching water availability in nature. This year the early spring moisture pinch was a little more extended than usual in some areas, so that varietal performance was slightly divergent from the usual. This publication reports the yields of some of the more common small grain varieties either presently or potentially available to the farmers of the state. These yields are determined in fair, comparative tests at a series of experimental stations and farms throughout the state, which are representative of major crop variety adaptation areas of the state. Annual yields, when considered in the light of longer period performance averages, and the production problems of a given area, can be a very valuable guide in the choice of crop varieties and often crops on the farm. It is for this reason that this information goes out to the state's farmers via the Extension Service, as established nationally under the Smith-Lever Act. The moving five year average now has left the very severe stem rust year of 1953 behind, and so the yield averages of some of the susceptible varieties will show recovery. Consequently, it is well to consider such attributes as disease resistance, heat tolerance and maturity along with yield, even though yield is the result of the action of all plant qualities - provided conditions lead to their expression.
