AGRICULTURAL SIGNIFICANCE OF RHIZOBIUM SPECIES FROM DIFFERENT SOURCES

Abstract

Strong demand for food necessitates efforts by researchers to create methods for sufficient production. Agricultural challenges include soil fertility loss, climate change, and increased pest infestations. Environmentally friendly practices such as the use of bio pesticides, bio fertilizers, and the return of crop residues are used to produce sufficient quantities in a healthy and sustainable farming system. The wide range of beneficial impacts of soil microorganisms, notably plant growth stimulation, emphasizes the need for more research and application in modern agriculture. Legumes are an important part of many people traditional diets around the world because they provide a slew of benefits to a soil and other crops produced alongside or after them in a variety of cropping systems. Legumes ability to fix atmospheric nitrogen in conjunction with rhizobia allows them to thrive in severely deteriorated soils. Is it, nevertheless, necessary to inoculate legumes on a regular basis? Rhizobia are extremely valuable agriculturally and economically since they are the primary supplier of nitrogen in agricultural soils. Aside from nitrogen fixation, several rhizobia strains have plant-growth-promoting features such phytohormone synthesis, siderophores, and 1-aminocyclopropane-1-carboxylic acid deaminase, as well as inorganic phosphate solubilization. Rhizobia have become important for both legumes and non-legumes as a result of these factors. Plant growth has been improved by screening and using effective rhizobial strains as inoculants. Plant growth has been improved by screening and using effective rhizobial strains as inoculant. The use of rhizobia as a bio fertilizer ensures crop yield while also reducing the demand for expensive and environmentally harmful artificial fertilizers. Rhizobia and other plant-growth-promoting rhizobacteria inoculated together resulted in increase in plant-growth promotion. Bioremediation properties of certain rhizobial strains have also been found.
