| Abstract: |
| This review synthesizes the economic and environmental impacts of maize-soybean intercropping systems relative to monoculture, serving as a scientific reference for advancing this practice in domestic agriculture. Through a systematic literature review, we collated and discussed various research findings on the economic and environmental ramifications of maize-soybean intercropping. The analysis revealed that maize-soybean intercropping enhanced land use efficiency, increased crop yields, improved agricultural income, reinforced the stability of agro-ecosystems, and reduced disease incidence. Maize-soybean intercropping stands as a vital agricultural technique with significant implications for sustainable development. Future studies should delve into the influence of varying row and plant spacings on intercropping efficiency, with a concerted focus on achieving comprehensive objectives such as food security, resource efficiency, ecological preservation, and economic improvement. The promotion of corn-soybean intercropping should be integrated with the overarching aim of fostering a robust and sustainable agricultural model. |
