Effect of GA₃ and NAA on Yield and Quality of Okra (Abelmoschus esculentus L)

A field experiment was conducted at Horticulture Instructional Farm, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during the kharif season 2012 to study the effect of GA₃ and NAA on yield and quality of Okra. Yield parameters like number of fingers harvested per plant, average weight of finger, yield per plant, yield per plot and yield per hectare and quality parameters like total number of pickings, thickness of finger and length of finger were analyzed. The experiment consisted of 16 treatments combination involving two growth regulators with four levels each (0, 25, 50 and 75 ppm). GA₃ and NAA (75 ppm) was found to be the most effective in increasing more number of fingers harvested per plant (15.10), total number of pickings (9.33) and thickness of finger (1.54 cm). Treatment combinations of (GA₃ 75 and NAA 50 ppm) increased average weight of finger (16.28 g) and yield per plant (0.232 g). Maximum length of finger (15.82 cm) was found treatment combinations of (GA₃ and NAA 50 ppm each).
