A pot culture experiment was conducted to study the effect of phosphatic fertilizers and vesicular arbuscular mycorrhizal fungi (VAMF) on the availability and uptake of phosphorus by soybean crop. Application of single super phosphate increased the mean dry matter yield of soybean by 17.7% over control (no P), followed by Tunisian rock phosphate (TRP). Mussorie rock phosphate and compacted Udaipur rock phosphate (MRP and CURP) increased the yield by 16.2% each. VAMF inoculation also significantly increased the dry matter yield. Application of phosphatic fertilizers significantly enhanced the available P content of the soil, which helped in increasing the dry matter yield of soybean. Single super phosphate was found to be significantly better in increasing soil available P over different rock phosphates. However, rock phosphates were better at maintaining soil available P. At 60 DAS, the uptake of P was 69.6% higher with SSP over control, followed by TRP (67.8 %), MRP (63.5 %), CURP (59.6 %) and URP (58.6 %). P uptake due to application of TRP and MRP along with VAMF was at par with SSP application.
