The increase in demand for food production due to the ever-increasing human population across world requires that should grow exponentially. For agricultural meet needs of requirements and demands there is a need sustainable practices will ensure availability without affecting soil health, biota fertility. Over years, many plant growth promoting bacteria (PGPB) strains have been identified reported provide number benefits plants, including enhanced nutrient uptake, growth, development as well increased resistance biotic abiotic stress. However only small them, are sold today, mostly formulations’ inability support bacterial survival both during after application agroecosystems. PGPB present these difficult constraints can be employed cell-free supernatants (CFSs), which broth cultures undergone various mechanical physical procedures eliminate cells. available literature suggests CFS may reliable source secondary metabolites agriculture. This review therefore discusses cell free supernatant microorganisms used crop offered pertinent information about upcoming studies on CFSs bio stimulant biocontrol agents significance, sources, applications, mechanisms action applications—both fertilizer agent were studied.
