Research Notes : Relay intercropping of soybeans and small grains
During the past two years we have been comparing several cropping systems: relay intercropping of soybeans with wheat, relay intercropping of soybeans with oats, and soybean monoculture. The purpose of the study was to determine if a need for separate breeding programs for these specialized cultural practices exists . Last year McBroom et al. (1979) reported a significant cultivar x cropping system interaction that would seem to indicate that such a need did exist.
