Abstract : The present investigation was carried out at the Research Cum Instructional Farm IGKV., Raipur (C.G.) having Inceptisols (Matasi) soil during kharif season of 2010. The experiment was laid out in randomized block design with 3 replications. The results revealed that amongst the different optimal, sub-optimal and integrated nutrient management practices using green manure, farmyard manure and chemical fertilizers, T10 consisting of 50% RDF + 50% N through green manuring recorded the highest growth, yield attributing characters and grain yield of rice (56.19 qha-1). T10 also recorded maximum net return (Rs. 46,117 ha-1), energy output (178.38 MJ x 103) and NPK content in soil. Application of 100% RDF (80:60:40 kg NPK ha-1) also proved superior over other integrated nutrient management systems consisting farmyard manure and rice residues for yield (55.19 qha-1) and energy output (176.75 MJ x 103).
