Effect of Reduced Tillage and Residue Incorporation as Sustainable Agricultural Practices on the Yield and Nutrient Uptake of Rice

In cereal-based farming, there is significant influence of tillage and residue incorporation as sustainable practices, although their role in crop production is still unclear. Two field trials were executed during winter seasons to evaluate the best-performing crop residue and tillage system for the nutrition and yield of rice at the Soil Science Field Laboratory of Bangladesh Agricultural University. In the first trial, residues from soybean, black gram, and rice were incorporated into the soil with 75% recommended fertilizer doses (RFD). The grain yields were 5.97, 6.21, and 6.10 t ha −1 , respectively in rice, soybean, and black gram residue-treated plots, which were increased by 77.15, 84.27, and 81.01%, respectively, over the control. In the second trial, the residues from black gram and rice were incorporated with 100% RFD under conventional tillage (CT) and minimum tillage (MT) for two years, where CT with black gram residue plus 100% fertilizer (CT-I 2 ) exhibited the highest grain yield of 6.69 and 6.88 t ha −1 , increasing by 7.61% and 8% over 100% RFD. Both CT and MT performed similarly, and their combination with legume residue strongly influenced crop performance and nutrient uptake. Therefore, incorporating legume residue under minimum tillage can be a sustainable approach for better rice yield and nutritional uptake.
