A field experiment was carried out during Kharif, 2023 at dryland farm of S. V. Agricultural College, Tirupati campus of Acharya N. G. Ranga Agricultural University, Andhra Pradesh. The experiment was laid out in a split-plot design with three replications and two Genotypes as main factor (G1- Dharani, G2- K-6), growth retardants as sub factor (T1- Control + RDF of NPK, T2- MH @ 2000 ppm at 20 DAS, T3- MH @ 2000 ppm at 45 DAS, T4- PBZ @ 250 ppm at 20 DAS, T5- PBZ @ 250 ppm at 45 DAS , T6- ABA @ 250 ppm at 20 DAS, T7- ABA @ 250 ppm at 45 DAS, T8- ABA @ 500 ppm at 20 DAS, T9- ABA @ 500 ppm at 45 DAS, T10- CCC @ 5000 ppm at 20 DAS, T11- CCC @ 5000 ppm at 45 DAS). The current experiment was conducted with an objective to study the impact of growth retardants on reduction of plant stature thereby enhancing the reproductive and assimilates partitioning efficiency. Results revealed that application of T5- PBZ @ 250 ppm at 45 DAS recorded higher Pod yield, Kernel yield, 100 kernel weight, protein content and oil content.
