Legumes play an important role in sub-Saharan Africa (SSA) farming systems through the provision of food, feed, fuel, income and a range of biophysical benefits, such as soil fertility enhancement and erosion control. However, their full potential is

Abstract Legumes play a key role in food and nutrition security, providing livestock feed and contributing to soil fertility, in mixed smallholder farms in sub‐Saharan Africa (SSA). The environmental conditions under which smallholder farming is pr

Livestock production is central to the livelihoods of smallholder farmers in low- and middle-income countries, but livestock are often poorly fed which limits their potential for reducing poverty. Efforts to improve livestock nutrition are often driv

In smallholder crop–livestock systems where maize (Zea mays L.) is a staple cereal, the stover is usually an important but low-quality ruminant feed. Maize stover has various competing uses, and optimal allocation of stover, particularly for forage

Limited supply of quality feed is the most common problem limiting livestock productivity in sub-Saharan Africa (SSA). Routine feed evaluation is indispensable for formulating balanced rations, feed characterization, safety, and minimizing the enviro

On low-input smallholder farms of Kenyan upland landscapes, erosion of nutrient-rich topsoil strongly affects crop yields. Where maize (Zea mays) is intercropped on erosion-prone slopes, intercropping can potentially reduce soil erosion. The objectiv
