A field study was conducted during Kharif 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P), India. The soil texture of the experimental plot was sandy loam, with a pH of 7.8, low organic carbon (0.35 percent), available N (243 kg/ha), available P (20.10 kg/ha), and available K (105 kg/ha). The Study was laid out in Randomized Block Design, with nine treatments consists of viz., 1 : (RDF 50% + FYM 5t/ha) +P₁ -3%, 2 : (RDF 50% + FYM 5t/ha) +P₂ - 6%, 3 : (RDF 50% + FYM 5t/ha) +P₃ - 9%, 4: (RDF 75% +FYM 5t/ha) + P₁ - 3%, 5 : (RDF 75% + FYM 5t/ha) + P₂ -6%, 6 : (RDF75% + FYM 5t/ha) + P₃- 9%, 7 : (RDF 100% +FYM 5t/ha) + P₁ -3%, 8 : (RDF 100% + FYM 5t/ha) +P₂- 6%, 9 : (RDF 100% + FYM 5t/ha) + P₃ - 9% and were replicated thrice. Results obtained that there was significant increase in yield parameters viz., Number of panicles /hill (12.53), Number of grains/hill (118.13), Panicle length (32.13 cm),  Test weight (24.27  g),Grain yield (6.28 t/ha), Straw yield (7.91t/ha) and Harvest index (44.25%) were recorded with the application of (RDF 100% + FYM 5t/ha) + P2-6%.The maximum Gross return (169650.00 INR/ha), Net return (115561.00 INR/ha) and B:C ratio (2.14) is recorded in treatment with (RDF 100% + FYM 5t/ha) +P₂-6%. Therefore, it is concluded that the application of (RDF 100% + FYM 5t/ha) +P₂-6% was more productive and economically feasible.
