The field experiment was conducted during kharif season of 2023 at Crop Research Farm, Department of Agronomy. The experiment was laid out in a Randomized Block Design with 10 treatments and replicated thrice. The treatments consisted of 3 levels of GA3 (50ppm, 75ppm and 100ppm) and 3 levels of IAA (30ppm, 40ppm, 50ppm) along with recommended doses of fertilizer and a control (20:60:40 kg N-P-K/ha). Application of GA3 at 100ppm and IAA at 50ppm (Treatment 9) recorded highest plant height (34.88cm), Nodules/plant(134.78), maximum plant dry weight (24.77), crop growth rate (23.64), No. of pods/plant (21.22), kernel yield (2.11kg/ha), test weight (242.30g),seed yield (3616.2 kg/ha), haulm yield (3718.4 kg/ha) and also recorded maximum gross return (186387.6 INR/ha), net return (139543.6 INR/ha) and B:C (2.97).
