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).
