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

Field experiment was conducted at Agricultural Research Station, Thirupathisaram during rabi 2017-18 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.
