Evaluating integrated nutrient management practices on yield and yield attributes of transplanted Boro rice (Oryza sativa L.)

Abstract

Two years field experiment was conducted during boro season of 2022-2024 to study the effect of organic and in-organic nutrient application in transplanted boro rice on yield and yield attributing characters in the Agricultural Experimental Farm of University of Calcutta, Baruipur, West Bengal, India. Integrated nutrient practices in cultivation is essential to keep the soil healthy for sustaining production as addition of organic nutrients more than that of synthetic fertilizers increase the organic carbon level of soil thus keeps the soil fit for crop production. There were ten treatments performed in randomized block design replicated thrice consisting of 50% RDF NPK+FYM 5 t ha-1, 75% RDF NPK+FYM 5 t ha-1, 50% RDF NPK+FYM 7 t ha-1, 75% RDF NPK+FYM 7 t ha-1, 50% RDF NPK+Vermicompost 2 t ha-1, 75% RDF NPK+Vermicompost 2 t ha-1, 50% RDF NPK+Vermicompost 3 t ha-1, 75% RDF NPK+Vermicompost 3 t ha-1, 100% RDF NPK (120:60:60) and Control plot. The results from pooled analysis indicated that 75% RDF NPK+Vermicompost 3 t ha-1 indicated best yield attributing characters along with highest grain and straw yield also best biological yield and harvest index was obtained. The control plot revealed lowest yield and yield attributing characters. 100% NPK of RDF also showed good result compared to other integrated nutrient practices where as least result was obtained from 50% RDF NPK+FYM 7 t ha-1 and 50% RDF NPK+FYM 5 t ha-1.
