Plant Growth-Promoting Bacteria As Inoculants In Agricultural Soils

  • October 31, 2019

Plant-microbe interactions in the rhizosphere are a determinant of the health of plants, soil fertility, and productivity. Plant growth-promoting bacteria (PGPB) is a bacterium that can promote plant growth and protect plants from diseases and abiotic stress through a variety of mechanisms.

Some of the important characteristics of bacteria, such as biological nitrogen fixation, phosphate solubilization, ACC deaminase activity, and the production of siderophores and phytohormones, can be rated as the promotion of plant growth (PGP) properties. You can get to know more about beneficial soil bacteria via an online search.

Inoculant bacteria can contribute to improving agronomic efficiency by reducing production costs and environmental pollution, as well as the use of chemical fertilizers, which can be reduced or eliminated if inoculants are efficient.

For bacterial inoculant to obtain success in increasing the growth and productivity of plants, some of the processes involved can affect the efficiency of inoculation, such as exudation by plant roots, the colonization of bacteria in the roots and soil health.

This review presents an overview of the importance of soil-plant-microbial inoculant for the development of efficient, microorganisms once PGPB been extensively studied represents a very diverse group of beneficial bacteria that are easily accessible.

The mechanism by which bacteria can affect plant growth differs between species and strains, so there is usually no single mechanism to promote plant growth. Research has been conducted on the ability of various bacteria to promote plant growth, including endophytic bacteria.
