Abstract:
A field experiment was conducted during kharif season of 2021 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.) India. The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction (Ph 7.2), low in organic carbon (0.48%), available N (108.0 kg/ha), available P (22.5 kg/ha) and available K (280.0 kg/ha). The experiment was carried out to find the performance of 15 hybrids, which laid out in Randomized Block Design (RBD) & replicated thrice. The experiment finding revealed that the Rice hybrid UR-4 performed better than other treatment viz. Maximum number of tillers/hill (11.16), more number of tillers/m² (393.50), maximum Plant dry weight (53.97g), Crop Growth Rate (56.42g/m²/day) and Grain yield (9.41 t/ha), Straw yield (14.24 t/ha) and Harvest Index (40.20%) However the maximum plant height (109.63 cm) were recorded in UR-4. The Panicle length (33.41 cm) and Filled grains/ panicle (176.46 No.) was recorded in UR-5 and minimum days to maturity were recorded in UR- 2. Highest gross return (INR 192860.67/ha), net return (INR 130553.67/ha) and benefit-cost ratio (2.10) were observed in hybrid UR-4 compared with another hybrid.
