Influence of Integrated Nutrient Management Practices on Yield and Nutrient Uptake of Rice under System of Rice Intensification

Abstract

 Field experiment was conducted at Agricultural Research Station, Thirupathisaram during rabi 201718 to study the effect of integrated nutrient management practices on rice under system of rice intensification. The experiment was laid out in a randomized block design with three replications. Biometrics such as number of panicles m-2, number of grains panicle-1, panicle length, grain yield, straw yield and nutrient uptake were recorded. Integrated Nutrient management significantly influenced the yield and nutrient uptake of rice. Application of 100% RDF + Poultry manure (3 t ha-1) + 3% Panchakavya foliar spray @ AT, PI & 50% flowering significantly influenced the yield and nutrient uptake of rice under system of rice intensification. The lowest yield characters, yield and nutrient uptake were recorded under 75% RDF alone.
