A field experiment was undertaken during rainy (kharif) seasons of 2010 and 2011 to evaluate the effect of integration of fertility levels with FYM and vermicompost on the growth, quality, productivity and profitability of hybrid rice (Oryza sativa L.) under system of rice intensification. The experiment was laid out in split plot design with 18 treatments combinations and replicated thrice. The results revealed that an application of 100% recommended dose of fertilizer (RDF) increased plant height (by 6.5%), LAI (7.6%) and also enhanced dry matter accumulation (12.60%), effective tillers/m2 10.1%), panicle length (6.9%), panicle weight (8.5%), filled grains/panicle (19.0%), test weight (11.0%), grain yield (19.0%) and straw yield (24.2%) over the 50% RDF. As regards on three levels of N (15, 30 and 45 kg/ ha) through organic sources, application of 45 kg N either through vermicompost or FYM gave higher values of growth parameters, yield attributes, grain and straw yield as compared to 30 kg N/ha either through vermicompost or FYM. Similar trend was observed in all the quality parameters like hilling (%), milling (%), head rice recovery, protein content and protein yield of rice. The integration of fertility levels and organic sources on monetary returns in which the maximum net return (₹59804/ha) was gain under 100%RDF along with 30 kg N/ ha through vermicompost was found to be most remunerative dose for rice hybrid ‘PHB-71’ under SRI.
