Rhizobacteria for Sustainable Agriculture: An Overview

Chhavi Jain


Several soil bacteria participate in the growth and development of plants, and are usually termed as plant growth promoting rhizobacteria. These bacteria colonize on or near plant roots and play vital role either directly or indirectly in health and productivity of different plant species. The plant growth promoting rhizobacteria facilitate plant growth by assisting in acquisition of essential nutrients and minerals, modulating plant hormone levels and by acting as biocontrol agents. This review provides an overview on the role of rhizobacteria in plant growth and development. Also, it gives an insight onto how the use of plant growth promoting rhizobacteria might decrease the global dependence on hazardous agricultural chemicals which destabilize the agro-ecosystems.

Keywords: BNF, phytohormones, phosphate solubilization, plant growth promoting rhizobacteria, rhizobacteria
