Agronomic Evaluation of Rice (Oryza sativa L.) Hybrids for the Agro-climatic Conditions of Prayagraj in Kharif – 2022, India

A field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) during Kharif, 2022. The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), organic carbon (0.75%), available N (269.96 kg/ha), available P (33.10 kg/ha), and available K (336 kg/ha). The experiment was laid out in Randomized Block Design with 10 hybrids each replicated thrice. Results was recorded as higher plant height (112.03 cm), number of tillers (16.34), plant dry weight (50.91 g/plant), crop growth rate at 80-100 DAT (32.14 g/m2/day), tillers/m2 (371.23), panicle length (29.73 cm), filled grains (245.87), grain yield/hill (31.37 g), seed yield (4.97 t/ha), straw yield (9.54 t/ha) were recorded significantly higher in hybrid R-170. However, harvest index (34.41 %) were recorded significantly higher in hybrid R-151. Further, the maximum gross returns (INR 128020/ha) and net returns (INR 78974/ha) and B:C ratio was highest in 1.61 were recorded significantly higher in hybrid R-170.
