Effectiveness of Paclobutrazole Application on Improvement of Groundnut (Arachis hypogaea L.) Yield Under Water Deficit Conditions

An experiment was carried out during the summer seasons of the year 2021 and 2022. A split plot design with three replications was used for an experiment that included irrigation as the main factor with three levels while paclobutrazole foliar spray as a sub-factor with four levels. Pod yield per plant, seed yield per plant, and harvest index were significantly higher with irrigation at 15-day intervals (I2) in the pooled data, whereas minimum recorded when irrigation at 20 days interval (I3) was given. The significantly higher harvest index, pod yield per plant, and seed yield per plant were recorded with the application of PBZ @ 200 mg/l (T3), whereas a minimum harvest index was noted with control (T1).
