A field experiment was conducted during kharif season of 2019 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.) to evaluate rice (Oryza sativa L.) hybrids under agro-climatic conditions of U.P. The experiment was carried out to find the performance of 10 hybrids, which laid out in Randomized Block Design (RBD) & replicated thrice. The experiment finding revealed that at 100DAT the significantly higher plant height was recorded in the treatment KHR-23(123.91 cm) and KHR-27 performed better than other treatment viz. tillers/m2 (356.67), dry weight (49.91g/hill). And the minimum unfilled grains/panicle was recorded significant in KHR-24(29.33) and the significantly highest test weight was recorded in KHR-23(27.59 g). The yield parameters viz. Panicle length (31.45 cm), Filled grains/panicle (285), grain yield/hill (28.14 g), grain yield (8.16 t/ha), straw yield (11.37 t/ha) was recorded significantly higher in KHR-27. The economics of gross returns (₹159574.0/ha), net returns (₹105527.3/ha), B: C ratio (1.95) was recorded higher in KHR-27.
