Abstract

Field investigations were carried out at the Experimental farm, Department of Agronomy, Annamalai University, Annamalainagar, to increase the crop growth rate and enhancing the productivity of rice by imposing nutrient management practices. The experiments were laid out in randomized block design with three replications. Integrated application of 75% recommended dose of N through fertilizer and 25% N through various organic manures (FYM, cow dung based vermicompost, cow dung and water hyacinth based vermicompost, enriched poultry manure compost, enriched coirpith compost, green manures and green leaf manures) with recommended dose of P and K were evaluated with farmers’ practice and absolute control. Among the different combinations, application of 75% RDN through fertilizer + 25% N through vermicompost (75% Cd + 25% Wh) had strikingly impressive effect on growth attributes (dry matter production, Leaf Area Index, crop growth rate), yield attributes (productive tiller m-2, filled grains panicle-1, fertility percentage), grain and straw yield of rice. This treatment was statistically on par with the application of 75% RDN through fertilizer + 25% N through vermicompost (100% Cd). Vermicompost prepared from cow dung as well as cow dung and water hyacinth were on par with each other in recording higher values. The integration of organic and inorganic forms of N excelled over the absolute control treatment.
