Plant Growth-Promoting Bacteria and Their Importance in Vegetable Production

Enhancing vegetable production with plant growth-promoting bacteria

Abstract

A large number of soil bacteria may colonize and promote plant growth and health on the surfaceinside of the root system. This community of bacteria, commonly known as PGPR, increases the growth of plants, including crops, in traditional and stressed soils. Moreover, several PGPRs indirectly promote crop processing by inhibiting various phytopathogens. Conclusively, PGPR has an effect on plant growth by nitrogen fixation, phosphate solubilization, mineral absorption, development of siderophora, antibiotics and hydrolytic enzymes. The PGPRs that are known for helping to develop a wide variety of plants including potatoes, carrots, onions, etc. belong to the Azotobacter, Azospirillum, Pseudomonas and Bacillus genera. Plants play an important part in supplying vital minerals, vitamins and fibers, which in staple starchy foods are not available in significant amounts. Therefore, the use of PGPR in vegetable cultivation is advised to maximize vegetable output without chemical inputs. Here the importance of PGPR in vegetable production in both common and abandoned soils is underlined.
