EXEMPLARY EMBODIMENTS OF THE PRESENT DISCLOSURE ARE DIRECTED TOWARDS METHODS FOR PREPARATION AND APPLICATION OF HOST-SPECIFIC EFFICIENT RHIZOBIUM BIOINOCULANT FORMULATIONS AND PRODUCTS THEREOF. THE PRESENT INVENTION ALSO DISCLOSES THE HOST-SPECIFIC EFFICIENT RHIZOBIUM BIOINOCULANT FORMULATIONS PREPARED BY SUCH METHODS. A MIXTURE OF FOREST RHIZOSPHERIC SOIL SAMPLES ARE COLLECTED AND LAYERED ALONG WITH A TEST SOIL FOR GROWTH OF A DESIRED LEGUME UNDER CONTROLLED CONDITIONS. THE PLANT THAT EXHIBITS DESIRED GROWTH PARAMETERS AND A LARGE PROPORTION OF ROOT NODULES IS SELECTED AND THE BEST SUPPORTING ROOT NODULES FROM THAT PLANT ARE COLLECTED FOR PRODUCING SUCH RHIZOBIUM BIOINOCULANT FORMULATIONS. THE INNOVATIVE FARMER FRIENDLY METHODS DISCLOSED HEREIN ARE EASY AS WELL AS COST-EFFECTIVE AND DOES NOT INVOLVE CULTURING RHIZOBIUM IN LAB CONDITIONS.
