Arid and semiarid regions are illustrious for stressed atmosphere primarily attributable to erratic precipitation, low fertility of soil, leading to low crop productivity with high uncertainty within the field conditions. In arid and semiarid areas all stresses preponderantly drought limits the expansion and yield of crops significantly inflicting the foremost fatal economic losses in agriculture. This form of abiotic stress, have an effect on the plant water relation at cellular and whole plant level, decrease N and C metabolism that result in modulate plant physiology and chemical process activity. The adaptation difference mechanism of plant drought tolerance might involve promotion of root extension, permitting associate economical water uptake. PGPR can serve as successful eco-friendly tools (Biofertilizers) to implement sustainable agricultural practices in all parts of the planet. PGPR assist host plant to cope with stresses and build changes in root morphology. Drought acceptance to the plants are typically elicited by PGPR inoculations that unit of measurement customized to water restricted soil conditions. Drought tolerance to the plants is induced by PGPR inoculations that are custom-made to water restricted soil conditions. PGPR utilizes induced system tolerance (IST) to induce physical and chemical changes that lead to increased tolerance of plants to abiotic stress. Azospirillum spp., isolated from arid areas will develop tolerance level in crop plants below water deficit condition. PGPR considerably promote seedling emergence, vigor and yield by competitory with different rhizobacteria through production of antibiotics, lytic catalyst, chemical compound siderophore and bacteriocin. The treatment of soil by biofertilizers not only enhances soil fertility but also enriches soil microorganism life. A number of the foremost established PGPR strains belong to the bacteria genus, Bacillus, Azospirillum, Azotobacter, Streptomyces, Klebsiella, Enterobacter, Alcaligenes, Arthrobacter, Flavobacterium, Burkholderia, Bradyrhizobium, Mesorhizobium, Rhodococcus and genus Serratia.
