Rhizospheric microbes have immense potentiality to synthesize and release various compounds, that are regulating plant growth as well as physical and chemical texture of the soil. In this small piece of research, we evaluated the plant growth promoting activity of two different carriers such as charcoal and talc based formulation of Bacillus species. It was observed that, the bio-inoculants were able to enhance the organic carbon, nitrogen, phosphorous and potassium in soil, there by promoting growth of test crop plants such as mung bean (Vigna radiata L.) and rice (Oryza satiava L.). Charcoal based formulation depicts higher plant growth promoting activity in comparison with other carrier. Moreover, the Bacillus specie showed antagonistic effect against different phytopathogens including Rahizoctonia solani (ITCC-186) and Fusarium oxysporum (ITCC-578). Thus, the charcoal based formulation of Bacillus specie can be used for plant growth promoting activity of various crops. Before field application extensive research is highly indispensable in this regard.
