Abstract

Field experiments were conducted during 2011–12 and 2012–13 at National Project on Organic Farming, JNKVV, Jabalpur (M. P.) consisting of two cropping systems (viz., Green manuring-basmati rice-wheat and basmati rice-berseem) and five organic nutrient management practices (ONM1–1/3 FYM+1/3VC+1/3 NEOC, ONM2-Panchagvya, ONM3–1/3 FYM+1/3 VC+1/3 NEOC+Panchgvya, ONM4-BD-501 and ONM5-BD-501+ Panchagvya). Rice-berseem cropping system had appreciably more available N and P in soil as compared to green manuring-rice-wheat system. Application of ONM3 resulted in apparently more available nitrogenas compared to ONM4. Thetotal uptake of nutrients (N, Pand K) was significantly influenced by the cropping system and nutrient management. The uptake of the nutrients was more in rice-berseem system than that of green manuring-rice-wheat cropping system. There were no remarkable changes in soil physical, chemical and microbial propertiesof the soil due to cropping systems and nutrient management practices.
