Highlights • We retrieved 44 publications and 199 observations comparing continuous cereal with grain legume-cereal rotation in SSA.• Cereal after legume yielded on average 0.49 t grain ha−1 or 41% more than continuous cereal.• Sustained residual benefits of legumes with large N applications indicate the importance of non-N effects.• Relevant non-N effects include improved P availability, changes in SOM, and in pest, disease and striga pressure.

撒哈拉以南非洲通过豆类轮作实现可持续集约化：综述

亮点 • 我们检索了 44 篇出版物和 199 项观察结果，比较了 SSA 中连续谷物与谷物豆类-谷物轮作。• 豆类后谷物平均产量为 0.49 吨谷物 ha−1 或比连续谷物多 41%。• 具有大的豆科植物的持续剩余收益N 应用表明非 N 效应的重要性。• 相关的非 N 效应包括提高磷的可用性、SOM 的变化以及病虫害和独脚金压力。
