Abstract

A field experiment was carried out at Agricultural Research Station, Buldana, Maharashtra, India for 10 years (2003–04 to 2013–14) to study effect of soybean crop residue on the yield of succeeding rabi crops and soil health with special reference to organic carbon at fixed site in split plot design with three replications. The main plot treatments comprised four crop residue management viz., wheat with residue incorporation, wheat with no residue incorporation, chickpea with residue incorporation, chickpea with no residue incorporation and sub-plot treatments were fertilizers i. e. 50, 75 and 100% recommended doses of fertilizers for rabi crops. The results revealed that soybean crop residue incorporation significantly influenced grain yield of both the wheat and chickpea crops. The application of 100% recommended dose of fertilizer i. e. 120: 60: 60 kg NPK/ha for wheat and 25: 50: 00 kg NPK/ha for chickpea gave significantly highest grain yield, gross monetary and net monetary returns as well as improved soil organic carbon content.
