EFFECT OF RHIZOBIUM AS A BIOFERTILIZER ON GROUND NUT AND BLACK GRAM

The main sources of bio- fertilizers are bacteria, fungi, cyanobacteria etc. Such bio-fertilizers are cultured and are used for inoculating seed or soil or both under ideal conditions to increase the availability of plant nutrients. Biofertilizer promotes plant growth and productivity has internationally been accepted as alternative sources of chemical fertilizer. Rhizobacteria effectively colonize plant root and increases plant growth by production of various plant growth hormones, P- solubilizing activity, nitrogen fixation and biological control activity (Deshwal et al., 2011).Rhizobacteria stimulate the growth of leguminous plants and they are able to fix atmospheric nitrogen into soil by interacting symbiotically with leguminous plants, using the nitrogenase enzyme complex (Kiers et al., 2003).Rhizobium is the soil microorganism that can survive in the soil or forms a symbiotic association with the host legume. The present study aims to harness the potential of symbiotic nitrogen-fixing Rhizobium bacteria as a sustainable biofertilizer. By focusing on isolation Characterization, mass production, and practical application, this research seeks to contribute significantly to sustainable agriculture, enhance soil health, and improve crop productivity while minimizing environmental impacts.
