Hybird Corn, Corn Yield Test, Agronomy, Varieties
Until recently replacement of open-pollinated corn varieties by hybrids has not been as rapid in South Dakota as in states farther east. This reluctance to change has been due primarily to the difficulty of ascertaining the hybrids which will produce the largest average yield under the extremely variable climatic conditions prevalent in the corn growing area of South Dakota. It has been the purpose of these tests to supply information to the purchaser of hybrid corn seed which will enable him to choose adapted high yielding hybrids for his area, and also to provide the producer of hybrid strains with the data necessary to the development of better combinations. As a result of the collection of such data by this and other means the hybrid corn acreage in South Dakota is increasing rapidly.
