Yield trials were conducted in four of the crop adaptation areas (Fig. 1) of South Dakota during 1961, The purpose of the tests is to supply farmers, ranchers and others in agri-business, information on the relative performance ability of the various hybrids entered under similar conditions of environment. The crop adaptation areas are based upon soil type, elevation, temperature, rainfall and other related conditions which comprise the environments for the respective test locations. In 1961, four tests were planted, all in eastern South Dakota. Entries in each test varied from 13 to 22 hybrids planted in replicated plots. Data obtained were yield, moisture per cent of ear corn at harvest and, at some locations, lodging. Tables following the text present the data obtained.
