Abstract
Investigations to find out the effect of sulfur (S), phosphorus (P), and molybdenum (Mo) application on the concentration and uptake of P by soybean, cv. Bragg, were conducted at Haryana Agricultural University. In greenhouse experiments on soil deficient in S and P, S was applied at 0, 40, 80, and 120 ppm as K2SO4, and P was applied at 0, 40, and 80 ppm, as Ca(H2PO4)2. The application of S showed a synergistic effect on the concentration of P to a certain level of applied S in different plant parts of soybean. The application of P up to 80 ppm increased the P concentration significantly, but Mo application produced an antagonistic effect and significantly depressed P concentration in leaves, stems, pod husks, and grains of soybean. Total uptake of P at both sampling stages increased significantly with 40 and 80 ppm applied S and P, but application of Mo decreased P uptake at maturity. The application of S, P, and Mo affected the concentration of P in various plant parts at both stages of crop growth. The concentration of P in 45− and 110 day-old leaves gave significant positive correlation with P uptake and grain yield.
