Production of Nitrogen Fixing and Phosphorous Solubilizing Liquid Bio-fertilizer for the Improves of the Crops Growth and Yield

Bio-fertilizers are the result of fermentation process that including efficient life soil microorganisms specially bacteria and fungi. They reform plant growth and productivity through deliver of easily utilizable nutrients. They are cost-effective and eco-friendly bio-inoculants having great potential to enhance agricultural crop yield in sustainable path. Bio-fertilizers are classified into different types based on their purpose such as nitrogen-fixing, phosphate-solubilizing, k-mobilizing, and other plant growth-promoting bio-fertilizers. Promoting plant growth by different way Solid-state fermentation (15%-40% moisture content) and submerged (liquid medium 95%moisture content) fermentation are two main types of fermentation used sample for the production of bio-fertilizers. Each type of bio-fertilizer was prepared by selection of efficient microbial strain that can be isolated from environmental sample in this study by using direct manipulation of the environmental sample (in quit) with selective microbial nutrient then by using absorption of ingredients we can analysis bacterial growth curve analysis. Finally, we do that affirmation of microbial sp. by using morphological and biochemical test. Its cultivation using specific nutrient medium by formulations of using liquid base (broth). So Bio-fertilizers was recommended and an effective substitutable matter for socio economic and environmental friend of chemical fertilizers (CF) for farm land productivity.
