A field experiment was conducted during two consecutive years of 2017-18 and 2018-19 at Agronomy research farm of ANDUAT, Kumarganj, Ayodhya to study the different moisture regime and integrated nutrients 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

Application of 75% NPK + 25% N through biocompost 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 of hybrid rice as compared to rest of the nutrient management. Highest gross (Rs 143803.95 ha -1 ) was fetched with 7cm Irrigation given at 1 day after disappearance of ponded water with 75% NPK + 25% N through biocompost (I1N2) followed by (Rs 135801.0 ha -1 ) 7 cm Irrigation given at 1 day after disappearance of ponded water and 75% NPK + 25% N through FYM (I1N4). Highest net return (Rs 99380.01 ha -1 ) and benefit: cost ratio (2.24) was fetched with 7cm Irrigation given at 1 day after disappearance of ponded water with 75% NPK + 25% N through biocompost (I1N2) followed by (Rs 90651.42 ha -1 ) 7 cm Irrigation given at 4 day after disappearance of ponded water and 75% NPK + 25% N through biocompost (I1N2). Minimum net return (Rs 64104.26 ha -1 ) and benefit: cost ratio (1.30) of hybrid rice was obtained with conventional irrigation and 50% NPK + 50% N through FYM (I4N5).
