Abstract: Field experiment was conducted during Kharif season of 2017 at Research Farm, Department of Soil Science and Agricultural Chemistry at Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani on zinc deficient Vertisol to study the zinc solubilization potential of different microorganisms in soybean crop. The experiment consist of sixteen treatment in which four laboratory pre-evaluated zinc solubilizing microbial cultures (Control, Pseudomona strita, Bacillus megaterium, and Trichoderma viride) and four graded doses of ZnSO4 (0,10,20,30, kg ha^-1) were used in the factorial randomized block design. The results emerged out indicated that, the availablility of N (185 kg ha^-1), P (18.53 kg ha^-1), K (661 kg ha^-1) and S (10.90 mg kg^-1). An increased with the interaction effect of pseudomonas strita along with ZnSO4 @30 kg ha^-1. The status of soc (5.84 g kg^-1) are improved with the combined apply of pseudomonas strata and ZnSO4 @ 30 kg ha^-1. The DTPA extractable Zn (0.66), Fe (3.71), Mn (7.92) and Cu (3.98) was significantly increased with incremental effect of zinc solublizers and zinc levels.
