Farmers are faced with many decisions in managing corn and soybean as new technologies are introduced, such as Bt corn hybrids, new pesticides, and new seed treatments. As problems with corn rootworm resistance to Bt corn continue to be found in Iowa, it is important to research methods to manage this pest. It is also important for farmers to adopt tillage practices that not only maximize profits, but also conserve the soil. The objective of these trials was to investigate what affect various corn and soybean management practices would have on grain yield.
