Dist. Ratnagiri (MS) during the academic year 2023-24. The study was conducted using a Randomized Block Design with eleven treatments and each replicated three times. The treatments included T₁ – Control (no dipping and no spraying), T₂ - Dipping and spraying with GA₃ 50 ppm, T₃ - Spraying with GA₃ 50 ppm, T₄ - Dipping and spraying with GA₃ 100 ppm, T₅ - Spraying with GA₃ 100 ppm, T₆ - Dipping and spraying with GA₃ 150 ppm, T₇ - Spraying with GA₃ 150 ppm, T₈ - Dipping and spraying with GA₃ 200 ppm, T₉ - Spraying with GA₃ 200 ppm, T₁₀ - Dipping and spraying with GA₃ 250 ppm and T₁₁ - Spraying with GA₃ 250 ppm. Among all the treatments studied the highest plant height (64.63 cm), plant spread (N-S) (44.79 cm) and (E-W) (38.89 cm), number of leaves (334.02), number of branches (78.73), leaf length (6.05 cm), leaf width (4.56 cm) and stem girth (13.26 mm) were recorded in the treatment T₄ - Dipping and spraying with GA₃ 100 ppm.
