Plant-bacteria-soil interactions are the determinants of soil fertility and plant health. The success in the use of the beneficial microorganisms requires an excellent understanding of the complex interactions taking place between the different components of the complex plant-soilmicroorganisms (Hani Antoun, 2012). The soil surrounding the germinating seed is known as spermosphere. This ecological niche is the first habitat used by any developed microorganisms by seed inoculation and supports microbial activity. This in turn influences plant growth. As the plant grows older the growing roots are surrounded by strongly adhering soil particles and this soil-root interaction zone is known as rhizosphere (Hani Antoun, 2012). Plant root, exudates the organic content into the rhizosphere and supports the microbial activities, termed by Hiltner as Rhizospheric effect (Flaishman et al., 1996). Soil bacterial genera are involved in various biotic activities of the soil ecosystem to make it dynamic for nutrient turn over and sustainable for crop production (Munees et al., 2014). Sufficient and balanced quantities of nutrients require for optimum plant growth (Almas Zaidi et al., 2010).
