Abstract: A field experiment was conducted to study the long-term effect of inorganic fertilizers coupled with farm yard manure, green manure and wheat cut straw on organic carbon, and available N, P, K. in soil. The rice-wheat cropping system significantly improved the organic carbon content and available N, P, K status of the soil by integrated use of fertilizer and organics. The highest grain and straw yield of rice and wheat were obtained with farm yard manure or Sesbania aculeata as green manure to meat 50 per cent N in conjunction with 50 per cent RDF in rice and 100% recommended dose of NPK through fertilizers (RDF) in wheat. The organic carbon content, available N, P and K were significantly influenced by the use of 50 per cent N through organic sources of nutrients in conjunction with 50 per cent RDF under rice-wheat cropping system.
