Sustainable sugarcane cultivation is critical for reducing environmental impacts and enhancing agricultural productivity. This study examines the role of biological nitrogen fixation (BNF) in reducing the reliance on synthetic nitrogen fertilizers in sugarcane farming; synthesizes findings from multiple studies to evaluate the effectiveness of BNF in improving nitrogen use efficiency (NUE), soil health, and crop yields. Key insights include the potential of legume cover crops to enhance soil nitrogen storage and microbial biomass, the genetic variability in BNF among sugarcane progenitors, and the influence of endophytic nitrogen-fixing bacteria on nitrogen metabolism in sugarcane. Additionally, this study highlights the environmental benefits of optimized water-fertilizer management and the synergistic effects of intercropping with legumes. The findings underscore the importance of integrating BNF strategies into sugarcane cultivation to achieve sustainable agricultural practices and reduce greenhouse gas emissions.
