In the present study the field experiment on “Effect of plant growth regulators on morpho-physiological parameters of Okra (Abelmoschus esculentus (L.) Moench) in Konkan condition’’ was conducted at Central Experiment Station, Wakawali, Tal- Dapoli, Dist Ratnagiri in summer season during the year 2023-24. The experiment was laid out in Randomized Block Design with two replications and thirteen treatments [T₁- NAA 50 ppm, T₂- NAA 100 ppm, T₃- NAA 150 ppm, T₄- NAA 200 ppm, T₅- GA₃ 50 ppm T₆- GA₃ 100 ppm, T₇- GA₃ 150 ppm, T₈ GA₃ 200 ppm, T₉- Seaweed extract 3 ml, T₁₀- Seaweed Extract 4 ml, T₁₁- Seaweed extract 5 ml, T₁₂- Absolute control and T₁₃- Control (Water spray)]. Observations were recorded for all morphological parameters such as mean plant height, mean number of leaves per plant, mean number of branches per plant, mean number of nodes per plant, mean internodal length per plant, mean total leaf area per plant, flower initiation days (Days to first flowering), number of flowers per plants. Findings revealed that Treatment T6 gibberellic acid (GA₃) at 100 ppm consistently outperformed other plant growth regulator treatments. T₆ gibberellic acid (GA₃) at 100 ppm demonstrated significant improvement in all morpho-physiological parameters.
