Abstract
A field experiment was carried out at Kashmir during kharij season 2012 to assess the response of rice to integrated nutrient management. Grain yield (8.06 t ha−1), straw yield (10.40 t ha−1) and growth parameters, viz plant height, number of tillers hill−1 and leaf area index were recorded higher in treatment T4 (recommended dose of fertilizers-RDF + poultry manure @ 2 t ha−1) compared to other treatments. The yield attributes like number of panicles m 2, number of grains panicle-I, panicle weight and harvest index was also observed significantly higher in treatment T4. The economic analysis showed that treatment T12 (75% RDF + inoculation of Azosprillum) showed maximum net return ( 88.72 x 103 ha−1) and benefit: cost ratio (3.79), followed by T6 (RDF + Azosprillum) and Ts (RDF + sheep manure @2 t ha−1).
