The environmental hazards resulting from the frequent use and application of mineral fertilizers, and the negative environmental impacts of chemical fertilizers and their rising costs, enhances the application of bio-fertilizer which is valuable in the sustainable agricultural practices. The continuous application of bio-fertilizer encouraged plant growth and productivity due to the presence of different strain groups such as nitrogen fixer, nutrient mobilization microorganisms which help in increasing the availability of minerals and their forms in composted minerals and increase levels of extractable of macro or micro-nutrients has increased significance effect of bio-fertilizers in different crop plants . Bio-fertilizer can be processed through Solid-state fermentation . Usually the retention period for the anaerobic digestion of agro-wastes at mesophilic temperature ranges between 20 to 40 days .
