The global demand for food production requires an enhancement in crop yield to meet the needs of the increasing population. However, soil degradation due to intensive agricultural practices, such as using pesticides and chemical fertilizers, poses a significant challenge to sustainable food production. Soil health and plant productivity are intricately linked to interactions among plants, soil, and microorganisms. Biofertilizers, containing living or dormant microorganisms, have emerged as a promising solution to enhance soil microbial status, stimulate natural soil microbiota, and improve nutrient accessibility and decomposition of organic matter. This review provide a comprehensive overview of the role of biofertilizers, including nitrogen-fixing, phosphorus-solubilizing, potassium-solubilizing, sulphur-solubilizing, and zinc-solubilizing biofertilizers, in promoting plant growth, improving soil fertility, and increasing crop yield. The efficacy of biofertilizers in various crops, such as wheat, cotton, soybeans, and peas, is discussed, highlighting their potential to reduce the reliance on chemical fertilizers, mitigate soil degradation, and contribute to sustainable agricultural development. Moreover, a case study on the impact of Rhizobium inoculation on crop yield and soil fertility provides valuable insights into the practical application and benefits of biofertilizers in agricultural systems. In conclusion, using biofertilizers presents a promising avenue for enhancing food security, promoting sustainable farming practices, and fostering economic development while ensuring environmental sustainability.
