Nitrogen fixing legume crops can be integral to support sustainable agriculture because they are rich in protein and are critical to food security by enhancing soil fertility. Even though they are productive, however, they are constrained by nutrient deficits, primarily of nitrogen and phosphorus. Biofertilizers improve soil health, mobilize nutrients, lessen reliance on chemical fertilizers, and slow down environmental deterioration. With the development of multi-strain inoculants and their integration into nanotechnology, biofertilizer technology has further progressed due to their increased efficacy. Nevertheless, biofertilizers are a crucial component of sustainable agriculture, even in the face of several environmental sensitivity and application barrier issues. Improved stress resilience, increased nutrient availability, and synergistic effects with chemical fertilizers are some of their potential. This review highlights the revolutionary role that biofertilizers-which are based on nitrogen-fixing bacteria, phosphate-solubilizing microorganisms, and mycorrhizal fungi-play in improving the uptake, nodulation, and production of legume crops. By addressing weaknesses with innovative formulations and education of farmers, they will work to their full potential in addressing agricultural productivity and ecological balance.
