Performance of Rice (Oryza sativa L.) Hybrids on Growth, and Yield under Agro-climatic Conditions of Prayagraj, U. P.

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 field was sandy loam in texture, nearly neutral in soil reaction (pH 7.2), low in organic carbon (0.35%), available N (108.0 kg/ha), available P2O5 (22.15 kg/ha) and available K2O (280.0 kg/ha). The experiment was carried out to find the performance of 10 hybrids, which laid out in Randomized Block Design (RBD) with three replications. To find the performance of 10 Rice hybrids. The result of experimentation revealed that the Rice hybrid UR-35 recorded significantly higher growth attributes viz. plant height (120.58 cm), number of tillers/hill (15 no.), plant dry weight/plant (55.91 g), CGR (40.50 g/m2/day), yield attributes viz., effective tillers/m2 (387 no.), panicle length (28.41 cm), test weight (26.45 g), and yields viz., grain yield per hill (28.37 g), grain yield (6.90 t/ha), straw yield (12.77 t/ha).
