Effect of different moisture regimes and nutrient management on yield attributes, yield and economics of hybrid rice (Oryza sativa L.)

Abstract

A field experiment was conducted during two consecutive years of 2017-18 and 2018-19 at Division of Agronomy, ANDUAT, Kumarganj, Ayodhya to study the different moisture regimes and nutrient management on yield attributes, yield and economics of hybrid rice. Result data revealed that 7 cm irrigation given at 1 day after disappearance of ponded water produced significantly more yield attributes viz., length of panicles, number of grains per panicle, weight of grains per panicle and 1000 grain weight, yield viz., grain and straw yield and harvest index and economics of hybrid rice. Highest Gross and net returns and benefit: cost ratio was recorded with conventional irrigation. Application of 100% RDF of NPK (150: 75 : 60 kg ha) through inorganic fertilizers recorded significantly higher length of panicle, number of grains per panicle, weight of grains per panicle and 1000-grain weight, grain and straw yield, harvest index, gross and net returns and benefit cost ratio of hybrid rice as compared to rest of the nutrient management.
