Abstract:
A field experiment was conducted during kharif season of 2021 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj, Uttar Pradesh, India on soil with sandy loam in texture to study the “Evaluation of Rice (Oryza sativa L.) Hybrids on Growth, Yield and Economics under Agro-climatic Conditions of Prayagraj, U.P.”. The experiment consists of Twenty-two Rice hybrids viz., UR-23, UR-24, UR-25, UR-26, UR-27, UR-28, UR-29, UR-30, UR-31, UR-32, UR-33, UR-34, UR-35, UR-36, UR-37, UR-38, UR-39, UR-40, UR-41, UR-42, UR-43, UR-44. The experiment was laid out in Randomized Block Design (RBD) with Twenty-two rice hybrids replicated Thrice. 50% of recommended dose of nitrogen and full dose of phosphorus and potassium was applied as basal application just before last puddling and remaining 50% of nitrogen was applied in two top dressings at 30 DAT and 58 DAT. Znso₄ was broadcasted before puddling. The study revealed that, among different Hybrids UR-38 produced significantly higher plant height (122.57 cm), number of tillers per hill (No.) (15.07), plant dry weight per hill (55.91 g), panicle length per hill (29.00 cm), number of filled grains per panicle (No.) (256.17), grain yield (6.85 t/ha) and straw yield (12.77 t/ha). The hybrid UR-37 recorded significantly minimum number of days to 50% flowering (45.67 days) and the hybrid UR-34 recorded significantly minimum days to maturity (84.67 DAT). Hybrid UR-38 also fetched highest gross returns (176172.00 INR/ha), net returns (122126.00 INR/ha) and benefit cost ratio (2.25) when compared to other hybrids.
