Abstract: Rhizosphere competence and plant growth promoting rhizobacteria (PGPR) of Pseudomonas fluorescens beneficial effects on plant growth and health of rice crop. P. fluorescens from different origins for their ability to colonize the rhizosphere of rice plants grown in natural soil. PGPR are known to influence plant growth by various direct or indirect mechanisms, P. fluorescens identified as important organisms with ability for plant growth promotion and effective disease management properties, root colonization by Pseudomonas fluorescens, biotic and abiotic factors affecting colonization and mechanisms of pathogen suppression. Role in biological suppression and growth promotion, promoting biotic resistance to pests, increased herbicide tolerance, enhanced, and effective control against abiotic and environmental stresses. The production of secondary metabolites siderophore, volatile compounds, HCN, enzymes, phytohormones and antibiotics, Pseudomonas fluorescens the production of antibiotics such as 2,4-diacetylphloroglucinol (DAPG), phenazine, pyrrolnitrin, pyoluteorin and biosurfactant antibiotics to enhance the disease resistance quality of plants. Rhizosphere competence of Pseudomonas fluorescens and their influence on growth and yield of rice, analysis of biological properties, growth and yield parameters. The vermicompost based formulation was used for sandy clay loamsoil and seedling treatments.­ The application of vermi-based formulation of Pseudomonas fluorescens in combination with Trichoderma viridae and Trichoderma harzianumat the three different dosages (@ 10g litre^-1 of water 50 and 500 kg per ha). Untreated control was kept for making comparison with treated.
