Thus, increasing crop yields has been mainly concerned with achieving food security in the way of sustained novel agricultural strategies. However, with the new tendency to accept natural products, natural fertilizers, bio-control methods and modern biotechnological approaches are being considered for this purpose while reducing the dependency on chemical methods. Since the rhizosphere is strategically placed between root and soil, much attention is given to manipulate it in order to achieve better crop production by increasing nutrition and health of plants. The mechanisms of action demonstrated by various microbes on various crops in providing these benefits to the plant is discussed. Particular emphasis is given to discuss the appropriateness of usage of the term biofilmed biofertilizer. The present status of the applicability of the rhizosphere microflora in improving crop productivity is also questioned. The modern studies on microbiomics of the rhizosphere in relation to genetics of the plant is given consideration as the means of manipulating the rhizosphere. Identifying the genes and transferring genes to different varieties of crops is suggested as the way forward.
