Effect of Phosphorous and Potassium on Growth Parameters, Yield and Yield Attributes of Chickpea (Cicer arietinum L.) under the Rainfed Condition in Chitrakoot, India

The present study investigate the effect of phosphorous and potassium on growth parameters, yield and yield attributes of chickpea (Cicer arietinum L.) under the rainfed condition in Chitrakoot, India. Field experiments were carried out to investigate the effect of phosphorus and potassium on chickpea growth parameters, yield components, and yield during the rabi season of 2021-22 at Rajoula Agriculture farm, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya Chitrakoot, Satna (M.P.). The experiment consist of nine treatments combinations in factorial randomized block design with three replications consisted of three levels of phosphorous (50, 60 and 70 kg ha-1) and three potassium levels (30, 40 and 50 kg ha-1). Chickpea variety IPC-2011-112 was grown with the recommended agronomic practices. On the basis of results emanated from investigation it can be concluded that among the growth parameters maximum plant height at 90 DAS is 37.40 cm, maximum number of branches at 90 DAS is 32.53 and maximum number of nodules plant-1 at 45 DAS is 46.00 during the study were associated with the treatment T9 [70 kg P2O5 ha-1+ 50 kg K2O ha-1]. Similarly, among the yield components and productivity parameters maximum values in relation to number of pod plant-1 (69.33), number of seed pod-1 (1.73), 100 grain wt. (22.66 gm) and grain yield (16.85 q ha-1) was also found in the treatment T9 [70 kg P2O5 ha-1+ 50 kg K2O ha-1].
