Abstract:
In recent years, food security, livelihood security, water security, environmental conservation, and preservation of natural resources have all become severe issues. Developing countries are grappling with these challenges while also dealing with the dual costs of climate change and globalisation. Increased food demand as a result of the world's rising population has spurred the worldwide use of fertilisers. Biofertilizers have a major impact on soil fertility and plant growth. Solubilize insoluble soil phosphates into soluble phosphates by fixing atmospheric nitrogen both with and without plants, improving phosphorus availability and secreting growth stimulating chemicals and supplies to inoculated plants. Inoculation of biofertilizers contributes to a reduction in the requirement for chemical fertilisers and can therefore optimise plant growth, yields and production quality. Inoculation of biofertilizers contributes to a reduction in the requirement for chemical fertilizers and can therefore optimize plant growth, yields and production quality. Biofertilizers viz. Nitrogen fixers, P solubilizers, bacteria releasing K, and mobilizers of nutrients were used. Hence, each aspect of the biofertilizer technology relevant to the sustained production of millets should be placed under scrutiny before its extensive use. Thus, the present review explains the biofertilizers generally used in millets, along with their impact on soil productivity and sustained fertility.
