Plant Growth Promoting Rhizobacteria (PGPR) is a beneficial microbe that occupies the rhizosphere of the plant, and is able to enhance crop productivity and offers an attractive way to replace chemical fertilizers, pesticides and supplements. Plants are immobile living organisms, so they cannot move to search for better conditions. PGPR helps the plant tolerate many types of environmental stresses, one of these stresses is drought stress. The studies reveal the important role of PGPR in agriculture and confirm that PGPR are very beneficial to the environment by increasing the crop yields under drought stress, in the presence of pathogens and in poor soils.
