Abstract: A field experiment was conducted at Horticulture Instructional Farm, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during the Kharif season 2012, respectively to study the effect of GA3 and NAA on growth and flowering of Okra. Growth parameters like plant height and stem thickness (90 DAS), average length of interned and leaf area per plant (60 DAS) and number of nodes per plant and flowering parameters like days taken for initiation of first flower, days taken for flower initiation to edible maturity, days taken for sowing to first picking and days taken for sowing to last picking 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 stem thickness (1.95 cm), average length of interned (4.98 cm), Minimum days taken for flower initiation to edible maturity (5.88) and days taken for sowing to first picking (115.38). Treatment combination of (g3n2) increasing plant height (85.96 cm) and leaf area per plant (2427.86). Were as maximum number of nodes per plant (18.34) found combination with (g3n3) and minimum days taken for initiation of first flower (42.09) and days taken for sowing to first picking (49.10) was found treatment combination of (g0n1) respectively.
