Abstract
Corn is South Dakota’s most important grain crop. It is grown on 4 million acres annually. South Dakota ranks ninth among the states as a corn producer, having one-twentieth of the national acreage and one-thirtieth of the production. The state may be divided into three areas on the basis of the place of corn on the farm: the eastern area, where corn is complementary to wheat and grazing; and the western area, where corn is supplementary grazing
