Short summary
Intercropping maize with forage legumes can benefit Ethiopian smallholder farmers by providing cheap nitrogen and valuable livestock feed. We measured N2O emissions and maize yields and found that high legume biomasses may enhance N2O emissions per unit of harvested maize but that, after mulching, legume N can partly replace expensive mineral N. Thus, legume intercropping can be a valid strategy in the framework of climate-smart agriculture in sub-Saharan Africa.
