Increasing land pressure and soil degradation, together with the limited availability of fertilizers, labour, equipment and technology, keeps production efficiency low for smallholder farmers. Maize (Zea mays L.) is the most farmed crop in Ethiopia, because it is seen as ideal food and cash crop, and is therefore cultivated throughout the country, in various agro-ecologies and socio-economic circumstances. Potentially, maize yield can be increased through the integration of legumes in the cropping system.
