Plant growth promoting Rhizobacteria: a novel approach towards sustainable agriculture

In the modern world, agricultural sustainability is essential since conventional agriculture won't be able to meet our future needs. In the field of agriculture, chemical fertilizers used for the control of pests, weeds, and pathogens and for the increase of crop yields negatively affect the ecosystem. An attractive alternative to traditional agricultural practices is the utilization of soil microorganisms that could promote PG and development. Plant growth-promoting Rhizobacteria (PGPR) live in the rhizosphere and use a variety of mechanisms to help in the process of plant growth. They can function as biofertilizers (improve nutrition content), biostimulants (produce phytohormones), and biocontrol agents (protect the plants against diseases). The use of PGPR raises hope for reducing food insecurity, maintaining a clean environment, and lowering the risk to public health. Therefore, it is crucial to accept biological agents globally. The main purpose of this review is to increase the usage of PGPR as a bio-inoculant in our research and to discuss the formulation design of PGPR in sustainable agricultural practices.
