AbstractVegetable production is an important economic activity and a major source of vitamins, minerals, and income in Ethiopia. However, the production of vegetables is much less developed than the production of food grains in the country. Vegetable production still needs improvement in combating biotic and abiotic threats with innovative technologies. Nowadays, excess use of chemical fertilizers to satisfy the increasing demand for food exerts deadly effects on soil microorganisms and contribute to the deterioration of soil fertility and an increase in atmospheric pollution. Several types of research are still going on to understand the diversity and importance of plant growth promoting rhizobacteria (PGPR) and their role in the betterment of vegetable production. PGPR facilitate plant growth directly by either assisting in the acquisition of nutrients (nitrogen, phosphorus, and other essential nutrients) or regulation of the levels of hormones. Indirectly PGPR decrease the inhibitory effects of various pathogens on vegetable growth and development in the forms of biocontrol agents. Some of the notable PGPR capable of facilitating the growth of vegetables such as potato, tomato, pepper, onion belong to genera of Pseudomonas, Bacillus, Azotobacter, Enterobacter, and Azospirillum. Hence, to optimize vegetable production with reduced input of mineral fertilizers and pesticides, the use of PGPR in vegetable cultivation is recommended.
