Optimum N Rate for Sustainable Rice-Wheat System Under Tillage and Crop Residue Management

Application of an optimum rate of nitrogen is very crucial to maintain the sustainability of a rice-wheat cropping system (RWS). A three-year field experiment was conducted on acid sandy loam soil to select the best N-management practice, along with tillage and crop residue (CR) incorporation for RWS. Changes in soil properties were assessed to determine the effect of tillage and crop residue application on soil fertility, loss and uptake of N,...
