Description

The final measure of the performance of any crop variety is its yielding ability in relation to that of other varieties of the same crop. Yield itself is the result of the interplay of many factors, including the hereditary ability of a variety to produce, the conditions of soil and climate under which it is grown, and the various yield reducing factors of the environment. As they differ in inherent qualities, which both affect yielding ability and yield limitations, varieties will differ. The successful estimation of the potentialities of any variety demands that it be grown under a wide variety of environmental conditions and at many locations. The yield tests of small grain varieties conducted by members of the South Dakota Experiment Station Staff and U.S.D.A. cooperators are designed to measure the performance of varieties of wheat, barley, rye, oats and flax under the variable conditions of climate and environ rent encountered in the state.The information obtained in these tests is used as a basis for making varietal recommendations for the guidance of farm operators. It also serves to provide useful knowledge about varieties in which there may be an interest, and in the evaluation of new selections originating in South Dakota as well as elsewhere. This evaluation must always be in terms of present varieties. Obviously, no single crop year measures all the conditions under which a variety can be grown. Several year of information on a variety are very desirable, and often necessary, before any final conclusions may be made as to its area of adaptation, and its true performance in relation to other varieties. In this report, the 1953 yields and performance data of a limited number of small grain varieties are presented. Annual yields of the same strains during the period 19A9-1952 are presented where available, as are appropriate yield averages for the entire five year period.
