In this study, corn yield was measured after 10 yr of various rotational sequences of corn, soybeans, and wheat or oats, and under three levels of weed management to determine the effects of land use history on crop yield. Corn yield varied significantly with both crop rotation and weed management. Com yields were lower after continuous corn or soybeans or immediately following corn, and higher after a cereal crop or a rotation including a cereal. Herbicide application alone maintained significantly higher corn yield than inter-row cultivation across cropping systems.
