An integrated nutrient management programme on hybrid rice was conducted for two consecutive years (2005 and 2006) during wet season for sustained crop production at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in a randomized complete block design with 11 treatments. The results of the study demonstrated that plant height, dry matter production, leaf area index and crop growth rate of hybrid rice cultivar was increased with increasing doses of N, P and K fertilizers. All these growth attributes showed their maximum values with 100% recommended dose of fertilizers (RDF) NPK @ 80:40:40 kg ha^-1. Both both years maximum number of panicles m^-2 (267 and 327), filled grain panicle-1 (116 and 158), 1000- grain weight (20.4 and 22.4g), grain yield (5.3 and 5.5 t ha^-1) and biological yield (11.13 and 11.75 t ha-1) was recorded with 100% RDF. The second highest figures of all the above characters were observed with 75% RDF and 25% RD of N through GLM. The net return and B:C ratio were Rs, 13,425 ha^-1 and Rs. 0.61 with 100% RDF closely followed by 75% RDF + 25% RDN through green leaf manuring.
