Abstract:
An experiment in a pot was conducted in 2018 during the Kharif season at the Experimental pot of Department of Agricultural Chemistry and Soil Science, School of Agricultural Science and Rural Development, Nagaland University, Medziphema to investigate the effect of phosphorus and potassium level on growth, yield and nutrient uptake by Soybean (Glycine max L. Merrill) in acid soil of Nagaland. The experiment was carried out in Factorial Completely Randomized Design (CRD) with three replications. Four levels of phosphorus (0, 25, 50, 75 kg ha^-1) and four levels of potassium (0, 25, 50, 75 kg ha^-1) were taken in treatments. The investigation reveals that phosphorus and potassium play a significant role in soybean crop which influence growth, yield and quality of the soybean. On the basis of these results, it is concrete that the combined application of 75 kg P₂O₅ ha^-1 and 75 kg K₂O ha^-1 under the present investigation is the optimum for increasing productivity of Soybean under acidic soil of Nagaland.
