Abstract
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 40 hybrids each replicated thrice. The highest plant height (130.14 cm), number of tillers (16.68), plant dry weight (58.85 g/plant), tillers/m2 (392.54), panicle length (28.41 cm), filled grains (252.45), grain yield/hill (28.63 g), test weight (25.63 g), and stover yield (12.77 t/ha) were recorded in hybrid R-190. Further, the gross returns (₹ 149730/ha) and net returns (₹ 100684.00/ha) and B: C ratio (2.05) were recorded in hybrid R-458.
