The yield obtained from any variety depends upon its adaptability to local conditions, soil type and the environment under which it is grown. All varieties recommended in this publication have some merit, but they also have some weaknesses which show up more some years than others. In some years, only early maturing varieties produce a crop, while in other years the late varieties give the highest yield. Some varieties are resistant to the common diseases, while others are susceptible and may result in crop failures. Because of these varying conditions no one variety is best for all locations. This list of recommended varieties for South Dakota is based on reliable and impartial information obtained from comparable test and demonstration plots located on experimental and private farms throughout this state. These recommendations are based not only on yield but also on earliness, disease resistance, quality and other characteristics. Yield data for recommended varieties are given in Agronomy Pamphlet No. 2, 1944, “1943 Crop Yields and Recommendations," available in county extension offices. Since there are usually several good varieties recommended for each adaptation area (cover page), the farmer should choose the one that meets the crop hazards which he regards more serious. Although the recommendations are not final but subject to change, it must be remembered that they are based on the most reliable information available. As more information is obtained new varieties will be added while some of those now included may be dropped.
