A project connected with the South Dakota University Agricultural Experiment Station was initiated in 1972 to evaluate alfalfa and corn yield response to a management scheme where a center pivot is used on more than one field. The project was to take place in the South Dakota climatic region and to include a limited soil moisture storage situation. In order to present the finding of the project and to evaluate the economics of such a scheme the following objectives of this study were established: 1. To develop production functions for corn and alfalfa that are applicable to South Dakota conditions and that can be used in irrigation analyses. 2 To make economic analyses of selected multiple field irrigation management schemes which utilize a center pivot irrigation machine on a shallow, droughty type soil.
