The research project titled "Effect of PGRs on yield characteristics of Cluster Bean (Cyamopsis tetragonoloba L. Taub)" has been conducted. The effects of nine different PGR treatments at different percentage concentrations on cluster bean development and yield characteristics were investigated in the village of Khudmudi under CHRS Sankara Patan, Durg (C.G.) during the summer of 2024-2025.Ten treatments and three replications were used in the Randomized Block Design field trial. Thiourea, GA₃, and NAA were among the three replication. The foliar application of GA₃ @100 ppm (T₃) significantly enhanced the yield and economics of cluster bean. Yield attributing characters such as the highest number of pods per plant (33.43)), greatest average pod weight (1.74 g), the maximum pod yield per plant (58.17 g) and total yield (64.63 q/ha) were achieved in T₃, compared to the minimum values in the control (T₀).

The highest economic returns were also recorded in T₃ with a maximum gross return of Rs. 2,00,359.09/ha, net return of Rs. 1,46,599.09/ha, and benefit: cost ratio of 2.73. The results clearly indicate that foliar application of GA₃ @100 ppm is highly effective in improving the productivity, and profitability of cluster bean cultivation.
