Zinc deficiency not only affects crop yields, but also nutritional quality and human health. Microbial transformation of unavailable forms of soil zinc to plant available zinc is an important approach contributing to plant zinc nutrition. Therefore, Nutrient uptake and biological activity in Tomato crop by zinc solubilizing bacterial isolates was tested under glass house condition. The study consisted of six treatments, each with five replications, including five different zinc solubilizing bacteria and uninoculated control, out of five bacteria B. aryabhattai was used as reference strain. The results revealed that tomato seedlings treated with B. aryabhattai and Bacillus sp. (PAN-TM1) substantially decreased rhizosphere pH and increased the macro and micro nutrient concentration in rhizosphere, plant and tomato fruit especially zinc concentration in the fruit ( and ppm respectively). | Nutrient uptake and biological activity in tomato by zinc solubilizing bacterial ZSB isolates
