Background and Objective: Okra keeps a significant role as a nutritious and medicinal vegetable that causes health benefits. The objective of the study was to evaluate the efficacy of this injection method applied on the flower bud at different concentrations of growth regulators. Materials and Methods: The experiment was carried out to investigate the effect of different concentrations of indole acetic acid (IAA), naphthalene acetic acid (NAA) and gibberellic acid (GA3) on okra pod set and size, soluble solids content (SSC), vitamin C and mineral contents using the flower injection method. Results: The lower concentrations (25 and 50 mg L1) of IAA and GA3 significantly increased the fruit set compared to the NAA. The higher concentration of 200 (mg L1) had a lower fruit setting than the lower concentration (25, 50 and 100) of IAA, GA3 and NAA. The higher pod/fruit size was obtained in IAA (31.01 cm²) and GA3 (30.8) as compared to the control (0) and NAA 25.6 and 14.6 cm²) at 100 (mg L1) of concentration. Pod size (38.4 was found significantly highest with 100 mg L1 of IAA concentration. In addition, the highest SSC was obtained by 100 mg L1 of IAA concentration as compared to the GA3 and NAA. The maximum vitamin C was found in IAA and GA3 as compared to the control (0) and 100 mg L1 NAA concentration. Moreover, higher mineral contents like K, Ca, Mg, Na and Fe were found in 100 mg L1 IAA and GA3 concentrations than 100 mg L1 NAA concentrations. The higher concentrations (100 and 200 mg L1) of IAA and NAA greatly decreased the healthy seed percentage as compared to the lower concentration. However, GA3 concentration increased the healthy seed percentage at higher concentrations. Conclusion: It seemed that IAA was a better growth regulator as compared to the GA3 and NAA for okra growth.
