biocontrol. Lately role of PGPR as an inducer in farming has established a lot of noteworthy

degree. Adopting PGPR applications, yields of crop plants (cereals, millets, pulses, oil seeds,
vegetables and fruit crops) have been significantly increased. PGPR may be beneficial as a

means of promoting plant growth as there is a worldwide reluctance in embracing foods
produced by genetic modification. The direct and indirect mechanisms of action of PGPR

based over Nitrogen fixation, Phosphorous availability, Potassium solubilization. Ion
chelation, modulation of phytohormones, HCN production etc have been illustrated.

The employment of artificial substances in agriculture in previous years has impaired soil
microorganisms as well as adversely influenced human vitalities and caused contamination of

resources including water bodies and air. In the contemporary world wherever the increasing
populace has tested to seek out further developed nourishment creation strategies, PGPR

will be designed as an efficient and practical answer for the gigantic scope creation of
numerous agribusiness items.
