A total 20 Pseudomonas species were isolated from BT cotton rhizosphere of 3 different regions of Nanded city. All these isolates were evaluated for plant growth promoting functional traits like plant hormones production, Phosphate solubilisation, Siderophore production and Silver nanoparticles production. The experimental results were analyzed using MINITAB (ver. 17) for paired t test (p 0.05) indicate positive co-relationship between produced metabolites, microorganism and silver nano particles in plant growth promotion activity.
