Abstract

The evolution of life in all forms is dependent on agriculture for food production and sustenance. Microorganisms present in
the soil such as plant growth-promoting rhizobacteria (PGPR) species are the family of rhizosphere bacteria that can promote
food crops production by several key mechanisms such as phosphate solubilization, siderophore production, nitrogen fixation,
phytohormone, and yield of volatile organic compounds, etc. The significance of PGPR in agriculture is gradually increasing as
a natural nourishment factor to reduce or replace the use of chemical fertilizers and pesticides. Potential plant growth-promoting
constituents provided at a larger quantity by the rhizosphere microorganisms are impacting the morphology of the plants,
indirectly. In this review, we are focusing on its role in agriculture sustainability due to its high raise in global food production
with a specific goal to reduce the use of synthetic chemical fertilizers and pesticides for health and environmental safety.
