Significant Role of Plant Growth Promoting Rhizobacteria in Agriculture Field

Abstract

Rapid population growth in the modern era has been associated with serious problems in the worldwide agro-ecosystems, which have resulted in lower production and a degradation of sustainable agro-ecosystems. Phytomicrobiome is one of the most effective methods, a superior option for agricultural sustainability and resolving both the issues of sustainability in the environment and worldwide food security. Plant growth-promoting rhizobacteria (PGPR) are free-living soil bacteria that may have both direct and indirect impacts on the growth of plants. The metabolism of plants can be significantly affected by bacteria that support the growth of plants and utilize their own metabolic pathway to dissolve phosphates, fix nitrogen, and develop hormones. Plant-beneficial rhizobacteria may reduce the world’s dependency on dangerous chemicals for agriculture that disrupt agroecosystems. PGPR provides farmers with a great alternative to lowering their use of artificial pesticides and fertilizers without having a negative impact on the environment or reducing crop yields. The use of PGPR as formulations or bioinoculants is a very efficient technique to increase agricultural productivity in a sustainable manner. This review enhances the perception of the PGPR, relevant outlooks on the various mechanisms of rhizobacteria-mediated promotion of plant growth have been explained in detail with recent research.
