Abstract: Field experiment was conducted during kharif season of 2018 at Research farm, Department of Soil Science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani to assess the response of spinach crop to various zinc solubilizers and graded levels of zinc on changes in zinc and other soil nutrients. Experiment consists of sixteen treatment in which four zinc solubilizers (Pseudomonas striata, Bacillus megaterium, Trichoderma viride and Control) and four graded levels of ZnSO4 (0 kg ZnSO4 ha-1,10 kg ZnSO4 ha-1, 20 kg ZnSO4 ha-1 and 30 kg ZnSO4 ha-1) were used in factorial randomized block design. Seed treatment of spinach was done with zinc solubilizing microbial cultures and application of zinc in graded doses at the time of sowing with recommended dose of fertilizers. Significantly highest values of available N, P2O5, K2O and S were noted in treatment receiving Psuedomonas striata + 30 kg ZnSO4 ha-1 interaction. DTPA Zn, Fe, Mn and Cu were noted maximum in treatment receiving Psuedomonas striata + 30 kg ZnSO4 ha-1.
