The Effect of Growth Retardants on Reprodutive Efficiency and Yield of Groundnut (Arachis hypogaea L.)

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. 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 along with yield. This article discusses various yield and reproductive efficiency related attributes of groundnut as influenced by growth retardants. The experimental results revealed that, the T5 (PBZ @ 250 ppm at 45 DAS) reported Maximum number of pegs per plant (58.50), number of pods per plant (28.89), shelling % (70.39) and harvest index (32.52 %). Among the two genotypes studied, G1 (Dharani) demonstrated more number of flowers (73), number of pegs per plant (50), number of pods per plant (26), shelling % (69) and harvest index (32 %).
