Southeast Research and Demonstration Farm
This project was designed to study the effects of planting corn and soybeans in 12-row strips as compared with planting corn as a single crop in a field. The reasoning behind planting corn and soybeans in strips is derived from the belief that corn plants will be better able to intercept light if more plants are exposed to an open edge like that found at the corn-soybean border. Interest in this study was derived from an article in the popular press where corn yields were reported to increase by as much as 100 bushels/acre when planted to strips of corn and soybeans. This study was designed to determine if a yield increase is possible and to see which corn rows in the strip are contributing to the yield increase.
