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

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 7.2), organic carbon (0.81%), 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. Based on the objectives taken maximum plant height (67.81 cm), number of tillers (9.98), plant dry weight (28.31 g/plant), Crop Growth Rate at 60-80 DAS (35.44 g/m2/day), relative growth rate (0.087 g/g/day), tillers/m2 (379.66), panicle length (27.74 cm), filled grains (111.94), grain yield/hill (29.18 g),seed yield (5.04 t/ha), stover yield (09.77 t/ha) and were recorded significantly higher in hybrid UR-300. Further, the maximum gross returns (₹154313/ha) and net returns (₹100267/ha) and B:C ratio was highest in 1.85 were recorded significantly higher in hybrid UR-300.
