Evaluating the effect of integrated nutrient management in transplanted rice (Oryza sativa L.)

Abstract

The goal of this Kuruvai season (June - September, 2023) field trial was to assess how integrated nutrient management (INM) influences the performance of the ADT 43 rice variety under transplanted conditions. The trial, conducted at the Annamalai University Experimental Farm, Annamalai Nagar, employed a randomized block design with nine treatments in triplicate. The treatments comprised of T1 - Control (no NPK); T2 - 75% RDF+ FYM @ 12.5 t ha-1 + 3% Panchagavya foliar spray @ AT, PI & 50% flowering; T3 - 75% RDF + Vermicompost @ 5 t ha-1 + 3% Panchagavya foliar spray @ AT, PI & 50% flowering; T4 - 75% RDF + Green leaf manure @ 6.25 t ha-1 + 3% Panchagavya foliar spray @ AT, PI & 50% flowering; T5 - 75% RDF + Pressmud @ 6 t ha-1 + 3% Panchagavya foliar spray @ AT, PI & 50% flowering; T6 - 50% RDF + FYM @ 12.5 t ha-1 + 3% Panchagavya foliar spray @ AT, PI & 50% flowering; T7 - 50% RDF + Vermicompost @ 5 t ha-1 + 3% Panchagavya foliar spray @ AT, PI & 50% flowering; T8 - 50% RDF + Green Leaf manure @ 6.25t ha-1 + 3% Panchagavya foliar spray @ АТ, PI & 50% flowering; T9 - 50% RDF + Pressmud @ 6 t ha-1 + 3% Panchagavya foliar spray @ AT, PI & 50% flowering. From these a major influence on the development and harvest of transplanted rice was observed.
