Abstract: A pot experiment was conducted in order to study the influence of different combinations of rock phosphate (RP), FYM and phosphate solubilizing bacteria (PSB) on phosphorus concentration and dry matter yield of soybean variety MACS-1460 grown in an acid soil of Manipur. Result revealed that plant P concentration and dry matter yield of soybean were affected significantly by the application of SSP, rock phosphate, FYM and PSB either singly or in combination. Fertilization of rock phosphate in presence or absence of PSB and FYM significantly increased P concentration and dry matter yield of soybean over control at different stages of crop growth. Comparatively higher P concentration and dry matter yield of soybean was recorded in soil treated with T11 (100% RD of P2O5 from RP + PSB2 + FYM at 5t ha-1) which is at par with T10 (100% RD of P2O5 from RP + PSB1 + FYM at 5t ha-1) at the time of harvest. Agronomic efficiency of rock phosphate as P source for crop production is enhanced by the solubility effect of FYM and PSB application. Application of PSB and FYM in combination enhanced organic P mineralization thereby increasing soil P availability, plant P concentration, growth and dry matter yield of soybean.
