Effect of integrated nutrient management on productivity and profitability of rice under SRI

Abstract

A field Experiment was conducted during kharif season in 2017 and 2018 to find out the nutrient management methods on productivity and profitability of rice under SRI. The experiment was laid out in randomize block design with three replication. The experiment consisted 10 treatment viz. T1 (control), T2 (100% RDF), T3 (125%RDF), T4 (150%RDF), T5 (75%RDF+25%FYM), T6 (75% RDF+25% V.C.), T7 (100% RDF+25% FYM), T8 (100% RDF+25% FYM), T9 (125% RDF+ 25% FYM) and T10 (125% RDF+ 25% V.C.). In case of integrated nutrient management the growth parameter character viz. plant height (cm), number of tillers (hill-1), leaf area index, dry matter accumulation (gm-2), crop growth rate (gm-2d-1), relative growth rates (mg g-1d-1), net assimilation rates (mg cm-2 d-1), yield attributes viz. number of panicles (m-2), length of panicle (cm), number of grain per panicle, test weight (g), grain yield and straw yield (q ha-1), harvest index (%) of rice was significantly recorded the maximum values with T10 (125% RDF+ 25% V.C.) during both the cropping seasons.
