1. Winter Wheat Residue Management Affects Corn Grain Yield and Nitrogen Requirement

Winter cereal cover crops are effective in reducing the nitrate-N (NO3-N) leaching from corn (Zea mays L.) and soybean (Glycine max L.) fields. An experiment was conducted as a randomized complete block design with split plot arrangement and four replicates to study wheat (Triticum aestivum L.) cover crop management practices on corn grain yield and nitrogen (N) requirement (economic optimum N rate; EONR). The main plots were four cover crop (CC) treatments:... F. Adeyemi, O. Adeyemi, E. Brevik, A. Sadeghpour
