The various concentrations of 2, 4-D, NAA and GA₃ significantly influenced the various parameters viz.; vegetative growth, yield and quality parameters and the highest (33.14 cm), (43.13 cm), (54.38 cm) and (61.43 cm) plant height at 45, 60, 75 and 90 DAT, respectively, maximum (163.14) leaves per plant, (15.20) branches per plant, (102.57) green chilli fruits per plant, minimum (38.35 days) to 50% flowering and the longest (8.27 cm) fruit, maximum (2.82 cm) fruit girth, heaviest (9.66 g) fruit weight and the highest (789.25 g/plant), (18.94 kg/plot), (21.92 t/ha) green chilli yield and (0.64 t/ha) dry red chilli yield were recorded under foliar application of GA₃ @ 50 ppm (T₈) treatment. However, the maximum (61.54%) fruit set per plant was observed in 2,4-D @ 10 ppm (T₂) treatment followed by (60.10%) and (58.94%) fruit set in 2,4-D @ 5 ppm (T₁) and 2,4-D @ 15 ppm (T₃), respectively. The foliar application of different concentrations of 2, 4-D, NAA and GA₃ showed the non-significant effect on number of flowers per plant. Results further indicated that the maximum net return (₹. 2, 99, 672.68 /ha) and highest B: C ratio (3.82) was recorded under GA₃ @ 50 ppm (T₈) treatment followed by (₹. 2, 54, 527.43 /ha) & B:C ratio (3.38) and (₹. 2, 38, 313.93 /ha) and B:C ratio (3.25) in GA₃ @ 75 ppm (T₉) and 2, 4-D @ 10 ppm (T₂), respectively in green chilli production under semi-arid conditions of Jaipur.
