A field experiment entitled “Impact of plant growth regulators on the growth and yield of summer Okra (Abelmoschus esculentus L.)” was conducted at the Research Cum Instructional Farm, Mohgaon, Saja, Bemetara (C.G.) during the Zaid season of 2024-25. The experiment was laid out in a Randomized Block Design with three replications and included ten plant growth regulator treatments: T₀ – Control, T₁ – GA₃ 25 ppm, T₂ – GA₃ 50 ppm, T₃ – GA₃ 75 ppm, T₄ – NAA 25 ppm, T₅ – NAA 50 ppm, T₆ – NAA 75 ppm, T₇ – Triacontanol 1000 ppm, T₈ – Triacontanol 1500 ppm, and T₉ – Triacontanol 2000 ppm. Observations were recorded for germination (days to first germination, germination percentage), growth (plant height, number of branches, internodal length, days to first flowering), and yield parameters (days to first fruit setting and harvest, fruit length and diameter, number of fruits per plant, fruit weight, and yield per plant, plot, and hectare).Results indicated that plant growth regulators significantly influenced germination, growth, flowering, and yield of summer okra. GA₃ at 75 ppm (T₃) was the most effective, producing earliest germination (6.00 days), highest germination percentage (92.38%), maximum plant height, branches, and internodal length, earliest flowering (35.67 days), longest and thickest fruits, highest number of fruits per plant (15.20), maximum fruit weight (15.49 g), and the highest fruit yield (158.18 q/ha), nearly double that of the control (71.05 q/ha). GA₃ at 25 ppm (T₁) and 50 ppm (T₂) also improved growth and yield compared to control but were slightly inferior to T₃.
