NOVELTY - An isolated bacterial strain (B1) selected from e.g. Ensifer meliloti FD, Rhizobium trifolii FD, Azorhizobium caulinodans KN, Rhizobium species RLG1, Azorhizobium species RLG2, Azorhizobium species RLG3, Rhizobium species RLG4 and Rhizobium species RLG5; and isolated fungal strain (F1) selected from e.g. Trichoderma virens 3107, Trichoderma viride LK, Trichoderma viride 3116, Trichoderma harzianum 3147 and Trichoderma harzianum G are new.    USE - In the microbial formulation for enhancing growth of plant selected from vegetable plant, legume plant, cereal plant, fodder plant, grass plant, fiber plant, oil seed plant, field plant, garden plant, greenhouse plant, house plant, tomato, eggplant, okra, squash, zucchini, bean, pea, soybean, rice, corn, sorghum, alfalfa, Bermuda grass, clover, cotton, and peanut plants; for enhancing the plant productivity and increasing agriculturally desirable trait selected from seed germination, height of the plant, leaf area, shoot length, root length, legume nodulation, grain yield, fruit yield, shoot weight, root weight, biomass, altered time for flowering, altered time for fruit formation, decreased disease incidence, and increased disease resistance (claimed); and for protecting plant from plant pathogens such as bacteria, fungi, virus, protozoa, parasitic organisms, mycoplasma, archaea and insect.    ADVANTAGE - The formulation is eco-friendly and environmentally safe; lowers the need for nitrogen containing fertilizers; solubilizes minerals; make available to the plant valuable nutrients such as phosphate; reduces and eliminates the need of using chemical pesticides and chemical fertilizers; reduces the cost of plant cultivation; alleviates negative health and environmental consequences associated with the use of toxic chemical compounds; minimizes environmental damage including obviating the need for artificial (synthetic) chemical pesticides and artificial chemical fertilizers that are harmful to ecosystems including humans, animals, insects and natural microbial populations; and enhances draught resistance in plant.    DETAILED DESCRIPTION - An isolated bacterial strain (B1) selected from Ensifer meliloti FD, Rhizobium trifolii FD, Azorhizobium caulinodans KN, Rhizobium species RLG1, Azorhizobium species RLG2, Azorhizobium species RLG3, Rhizobium species RLG4, Rhizobium species RLG5, Rhizobium species RLG6, Azorhizobium species RLG7, Rhizobium species RLG8, Azorhizobium species RLG9, Rhizobium species RLG10 and Rhizobium species RLG11; and isolated fungal strain (F1) selected from Trichoderma virens 3107, Trichoderma viride LK, Trichoderma viride 3116, Trichoderma harzianum 3147, Trichoderma harzianum G, Trichoderma harzianum LK, Trichoderma longibrachiatum 3108 fungal strain are new. INDEPENDENT CLAIMS are included for the following:    (1) a microbial formulation (M1) comprising a nitrogen fixing bacteria isolate, a phosphate solubilizing microbial isolate, a Rhizobacterial isolate, and a biocontrol microbial isolate;    (2) a mixture of bacterial isolates or a mixture of fungal isolates;    (3) microbial formulation (M2) comprising mixture of bacteria isolates (B1) and mixture of fungal isolates (F1); and    (4) enhancing plant growth involving providing microbial formulation containing mixture of bacterial mixture and fungal mixture, and plant; and applying the microbial formulation to a plant for enhancing plant productivity.
