The persistent and uncritical application of chemicals as suggests that to boost crop growth, development and yields for many years has become problematic to agricultural property due to the adverse effects these chemicals wear the turn out, customers and useful microbes within the scheme. Therefore, for agricultural productivity to be sustained there area unit desires for higher and appropriate preferences which might be friendly to the scheme. the employment of microorganism metabolites has become a gorgeous and additional possible preference as a result of their versatile, degradable and eco-friendly, in contrast to chemicals. so as to attain this aim, it's then imperative to explore microbes that area unit terribly getting ready to the basis of a plant, particularly wherever they're additional focused and have economical activities referred to as the rhizosphere. intensive forms of bacterium, archaea, fungi and alternative microbe’s area unit found inhabiting the rhizosphere with varied interactions with the plant host. Therefore, this review explores varied useful microbes like bacterium, fungi and archaea and their roles within the setting in terms of acquisition of nutrients for plants for the needs of plant growth and health. It additionally discusses the impact of root exudate on the rhizosphere microbiome and compares the 3 domains at molecular levels
