Potential of PGPR in Improvement of Environmental-Friendly Vegetable Production

Abstract

Plant growth promoting rhizobacteria (PGPR) can directly cause enhanced plant growth, early seed emergence or improvement in crop yields by supplying biologically fixed nitrogen and increasing minerals uptake, producing and secreting plant growth regulators and other beneficial substances. Also, PGPR indirectly influences the plant growth promotion by suppressing of pest and diseases in vegetables. Hence, replacement of chemical fertilizers and pesticides is required because of the adverse effect of these chemicals and their residues seriously pollute the environment, impart and also threaten the health of human and animals. Thus, people are focused on healthy products not only for growing vegetables but also for all agricultural products. In recent years because of increasing food-borne illnesses, the importance and potential of PGPR is hereby discussed for improvement of sustainable environment-friendly vegetable production for healthy human nutrition with special reference selected vegetable species, such as tomato, pepper, melon, radish and lettuce.
