Growth and Yield of Rice (Oryza sativa L.) under Agro-climatic Zone of Prayagraj, India

Abstract

During Kharif 2022, a field experiment was done on sandy loamy soil at Crop Research Farm, Naini Agriculture Institute, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment was designed in Randomised Block Design and replicated three times, using ten hybrids, R-205, R-210, R-212, R-218, R-242, R-248, R-256, R-300, R-305, and R-311. Results indicates that R-305 significantly enhanced the growth parameters Days to 50% Flowering (74.66 DAT), Days to maturity (106.93 DAT), Filled grains/panicle (175.82), Unfilled grains/panicle (48.39), and Grain yield/hill (28.82 g/ha) in the field trial. R-305 also had the highest gross return (INR 200625/ha), net return (INR 151579/ha), and B:C ratio (3.09). R-311 had the shortest amount of Days to 50% flowering (68.00 DAT), Days to maturity (92.71 DAT), and unfilled grains/panicle (27.25). It was determined that the hybrid R-305 produced the highest grain yield. It also achieved the highest gross return, net return, and B:C ratio.
