Abstract: The field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) during Kharif, 2023. The treatments consisted of three levels of sulphur (10, 25 & 40 kg/ha) and three levels of plant growth regulator (GA₃ 50 ppm, NAA 100 ppm, GA₃ 25 ppm + NAA 50 ppm). The experiment was laid out in a Randomized Block Design with ten treatments each replicated thrice. The treatments which are T₁: 10 kg/ha Sulphur + GA₃ 50 ppm, T₂: 10 kg/ha Sulphur + NAA 100 ppm, T₃: 10 kg/ha Sulphur + GA₃ 25 ppm + NAA 50 ppm, T₄: 25 kg/ha Sulphur + GA₃ 50 ppm, T₅: 25 kg/ha Sulphur + NAA 100 ppm, T₆: 25 kg/ha Sulphur + GA₃ 25 ppm + NAA 50 ppm, T₇: 40 kg/ha Sulphur + GA₃ 50 ppm, T₈: 40 kg/ha Sulphur + NAA 100 ppm, T₉: 40 kg/ha Sulphur + GA₃ 25 ppm + NAA 50 ppm, T₁₀: Control (NPK 20:60:40 kg/ha). The results showed that application of sulphur at 25 kg/ha with GA₃ 25 ppm and NAA 50 ppm (Treatment-6) recorded highest maximum plant height (44.85 cm), plant dry weight (34.29 g), number of pods per plant (11.67), number of kernels per pod (2.20), seed index (34.10 g), seed yield (1.94 t/ha), shelling Percentage (69.23%) and haulm yield (5.67 t/ha). The treatment also recorded maximum gross return (INR. 1,47,071.68/ha), net return (INR. 1,01,134.61/ha) and B: C ratio (2.11).
