摘要

A field experiment was carried out at Krishi Vigyan Kendra, Katihar, Bihar in jurisdiction of Bihar Agricultural University Sabour, Bhagalpur during 2014 to 2018 with the objective to find out suitable crop residue management option under rice- wheat cropping system in Inceptisols of Seemanchal area of Bihar. The results after four years clearly indicates that the crop residue management practices involving? incorporation of residues improved favorably and significantly the soil properties such as bulk density, infiltration rate, mean weight diameter, aggregate stability, electrical conductivity, organic carbon, available nitrogen, phosphorus and potassium, bacterial and fungal population, enzyme dehydrogenase and phosphatase activity in the soil and increased the grain yields of rice and wheat crop in the system over removal or burning of crop residue practices. Due to increased availability of readily decomposable organic matter in the form of crop residue and freshly incorporated green manure, the microbial population increased dramatically when crop residues are incorporated in the soil which might be responsible for increased enzyme phosphatase and dehydrogenase activity, decrease in bulk density, increase in granulation and aggregation and thus infiltration rate. The incorporation of crop residues with or without green manuring found promising for the environmental friendly and effective utilization of the crop residues under prevailing rice wheat system in this area.
