Effect of Integrated nutrient management practices on productivity and profitability of Rice (Oryza sativa L.)

Abstract

A field experiment was conducted during kharif season of 2018 at Genetics and Plant Breeding Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya. to study the effect of integrated nutrient management practices on rice productivity and profitability. The experiment was laid out in randomized block design with 8 treatments with 3 replications. Among the INM treatments, 100% RDF alone was found to be most profitable in terms of productivity, and profitability. The crop receiving 100% RDF alone recorded the maximum plants height (110.30 cm), no. of tillers (481.00 m-2), dry matter accumulation (573.96 g m-2), effective tillers (14.60), grain per panicle (120.0) Panicle no. (391.00 m-2), test weight. (23.90 g) grain yield (41.26 q ha-1), straw yield (54.40 q ha-1) harvest index (43.13%) and produced maximum net return (Rs. 32444) with higher B:C ratio (0.72).
