PLANT GROWTH PROMOTING RHIZOBACTERIA: ITS POTENTIAL APPLICATIONS AND THE EMERGENCE OF AGRICULTURE

Plant growth promoting rhizobacteria (PGPR) is a group of microbes that colonize the plant roots and benefit plants by providing growth of the plant. It is also regarded as an attractive alternative of chemical fertilizer, by enhancing the use of PGPR we can reduce soil pollution, increase fertility of the soil. They also helps in nitrogen fixation in legume plants and also increase the supply of micronutrients such as phosphorus, sulphur, iron, zinc, cobalt, nickel etc. Furthermore, they helps in control of different plants related diseases such as fungal and bacterial diseases. PGPR also helps in enhancing of seedling germination, stand health, plant vigour, plant height, shoot weight, nutrient content of shoot tissues, early bloom, chlorophyll content and increased nodulation in legumes. Scientific researchers group are involved in the finding of different application of PGPR, its potential effect and mechanism. This review paper focuses on the benefical effects of PGPR.
