ABSTRACT

The growth of plants promoting rhizobacteria (PGPR) has gained widespread importance in agriculture. These are beneficial bacteria found in nature that live actively in plant roots and improve plant growth and increase agricultural productivity.. (PGPR) promoting plant growth shows an important role in the sustainable agricultural industry. The increasing demand for crop production is a major challenge nowadays, with a significant lack of use of synthetic chemical fertilizers and pesticides. The use of PGPR has proven to be an environmentally sound way of increasing crop yields by facilitating plant growth through direct or indirect mechanisms. The mechanisms of PGPR include regulating hormonal and nutritional balance, inducing resistance against plant pathogens, and dissolving nutrients for easy uptake by plants. Furthermore, PGPRs show synergistic and antagonistic interactions with microorganisms within the rhizosphere and in bulk soils, which indirectly increases plant growth rates. There are several bacteria species that act as PGPR. This review summarizes the methodology of PGPR as a bio-fertilizer in agriculture.
