Abstract

The field experiment, titled "Effect of Phosphorus and Gibberellic acid on Growth and Yield of Groundnut," was carried out in Zaid 2023 at the Crop Research Farm at the Department of Agronomy, SHUATS, Prayagraj (U.P.).Three doses of phosphorus (30, 40, and 50 kg/ha) and gibberellic acid (80, 100, and 120 ppm) applied as foliar sprays were evaluated in the experimental treatments, along with a control plot.The experiment was laid out in Randomised Block Design (RBD) with 10 treatments and replicated thrice.The treatment of 50 kg/ha of phosphorus and 100 ppm of gibberellic acid resulted in a considerably higher maximum plant dry weight (32.50 gm) at 80 DAS, 25.70 pods/plant, 37.13 g seed index, 2.24 t/ha kernel yield, and 2.90 B:C ratio.
