Abstract
Three main areas of cover crop interseeding (cover crop species selection, establishment timing, and seeding method) need further research to understand how these interact with modern corn hybrids under Iowa climate and soil conditions. Further exploration of these factors will fill a knowledge gap to guide best management practices for interseeding cover crops into a corn cash crop. To develop best management practices for interseeding cover crops into a corn cash crop, this project aims to evaluate the effects of interseeded cover crop species, establishment timing, and seeding method on corn productivity. These experiments will help clarify treatment effects on 1) cover crop establishment, biomass accumulation, and nutrient uptake; 2) corn growth, productivity, and nutrient uptake; and 3) weed community and diversity.
