1. Corn Nitrogen Requirement in Winter Cereal Cover Crop Trials in Southern Illinois

Winter cereal cover crops, including wheat (Triticum aestivum L.) and winter rye (Secale cereale L.) are recommended as the best in-field management strategy by the Illinois Nutrient Loss Reduction Strategy (INLRS) to minimize nitrate-N leaching to the Mississippi River Basin and the Gulf of Mexico. We evaluated the effect of wheat and winter rye on corn grain yield, and nitrogen (N) requirement. Treatments were laid out in a randomized complete block design with four replic... A. Sadeghpour, O.
