Influence of plant growth regulators on dry matter production and yield attributes of Kharif groundnut cv. GJG-31

Abstract

A field experiment was conducted during the kharif 2018 at Cotton Research Station, Junagadh Agricultural University, Junagadh to study the effect of plant growth regulators on dry matter production and yield attributes of groundnut. The investigation was carried out in RBD design with three replications and foliar application of different concentration of growth regulators such as PBZ (200, 250 ppm), TRIA (5, 10 ppm), BR (10, 15 ppm), SA (25, 50 ppm), and water spray at 40 & 55 DAS. Experiment results revealed that application of PGRs increased the total dry matter production and increase was more in SA @ 50 ppm treated plants. Highest partitioning of dry matter to reproductive parts was also observed in SA @ 50 ppm treated plants. Significantly higher no. of filled pods per plant (14.44), shelling percentage (74.64%) and yield (1986.49 kg ha-1) were observed in SA @ 50 ppm treated plants.
