The present investigation was undertaken during kharif season of 2013-14 at the Research farm, Department of Soil Science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani to find out efficient strains of zinc mobilizing microorganism for the growth, yield and zinc availability in soils of Bt cotton grown on Vertisol. Results revealed that inoculation of microbial cultures Trichoderma viride along with recommended dose of fertilizer (NPK) significantly improved the growth and root parameters. Seed cotton and Dry matter yield was also significantly increased with the inoculation of RDF + Trichoderma viride followed by RDF + Pseudomonas striata. Inoculation of microbial cultures along with RDF increased zinc availability in soil as compared to RDF alone.
