Agriculture is the major backbone of human evolution, as it has been considered from the very early period of human civilization. The increasing demand for food has been mitigated to enhance crop productivity using chemical fertilizer. Our environment as well as crop quality have been largely affected by the abrupt use of chemical fertilizer. Biofertilizers have been introduced into the field of agriculture to overcome the hazardous side effects of chemical fertilizer. But the small shelf life and target specificity of biofertilizers lead to the development of nano-biofertilizers. The nano-biofertilizer is a successful outcome of the hybridization of nanoscience and biotechnology. The use of nano-biofertilizers has been gaining more importance nowadays because of its potential to enhance soil quality, plant growth, and crop production. Doping nanoparticles into biofertilizers increases the longevity, stability & efficiency of biofertilizers to several fold. It has been synthesized by the combination of a variety of microorganisms with nanoparticles. This review describes the present status and future prospects of the nanobiofertilizer along with its usefulness and disadvantages that motivate the future researchers to explore further in this field.
