Agronomic evaluation of private sector rice (Oryza sativa L.) genotypes under agro-climatic zone of Prayagraj U.P.

Abstract

The field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) during Kharif, 2023. 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 9 hybrids each replicated thrice. Based on the objectives taken maximum plant height (66.53 cm), number of tillers/hill (9.88), plant dry weight (27.67 g/plant), Crop Growth Rate at 60-80 DAS (25.69 g/m2/day), tillers/m2 (395.2), panicle length (27.74 cm), filled grains (106.96), grain yield/hill (30.94 g), seed yield (6.83 t/ha), stover yield (12.77 t/ha) and harvest index (38.86 %) were recorded significantly higher in hybrid R-120. Further, the maximum gross returns (INR 162533.00/ha) and net returns (INR 108487.00/ha) and B:C (2.01).
