Response of different moisture regimes and nutrient management on growth, yield and water use efficiency of hybrid rice (Oryza sativa L.)

Abstract

A field experiment was conducted during 2017-18 and 2018-19 at Agronomy research farm of ANDUAT, Kumarganj, Ayodhya to study the effect of different moisture regime and integrated nutrients management on growth, yield and water use efficiency of hybrid rice. Result data revealed that 7 cm irrigation given at 1 day after disappearance of ponded water resulted significantly higher growth attributes viz., plant height, number of shoots per running meter, leaf area index and drymatter accumulation and yield viz., grain and straw yield and harvest index of hybrid rice. Maximum water use efficiency was recorded with 7cm irrigation given at 4 DADPW. Application of 75% NPK + 25% N through biocompost recorded significantly higher plant height, number of shoots per running meter, LAI, drymatter accumulation per plant, grain and straw yield, harvest index and water use efficiency of hybrid rice as compared to rest of the treatments.
