Title: Efficiency of Antagonistic PGPR isolates of Bt and non Bt cotton rhizosphere from Telangana on seed germination and seedling vigor index
Abstract: Plant growth promoting rhizobacteria (PGPR) are beneficial bacteria that colonize plant roots and enhance plant growth by a wide variety of mechanisms. In the present study, a total of 76 bacterial strains isolated from the rhizosphere of Bt and Non Bt cotton (Gossypium hirsutum L.) plants were screened preliminarily for antifungal activity against Fusarium oxysporum f. sp. vasinifectum and 23 were selected. Study of seed germination and seedling vigour index under the influence of 23 antifungal selected isolates was performed. Further they were characterized on the basis of colony morphology, gram staining. These PGPR strains were observed to be effective in improving seed germination and vigour index. Thus, use of biological application of these free living plant growth promoting rhizobacteria (PGPR) may help to minimize the amounts of chemical fertilizers to be added, to improve plant growth, thereby decrease the production cost and environmental risks.
