The combined application of organic resources (ORs) and mineral fertilizers is increasingly gaining recognition as a viable approach to address soil fertility decline in sub-Saharan Africa (SSA). We conducted a meta-analysis to provide a comprehensive and quantitative synthesis of conditions unde...

Legume-cereal rotations are an essentialcomponent of integrated soil fertility management inlow-input cropping systems, but strategies are needed toincrease phosphorus (P) fertilizer use efficiency in suchsystems. These may include preferential targeting of Pto one of the crops in the rotation cy...

In Maraba, Southwest Rwanda, coffee productivity is constrained by poor soil fertility and lack of organic mulch. We investigated the potential to produce mulch by growing Tephrosia vogelii either intercropped with smallholder coffee or in arable fields outside the coffee, and the effect of the m...

Cassava intercropping is a common practice in sub-Saharan Africa. In terms of growth pattern, canopy development and nutrient demand, grain legumes are well suited for intercropping with cassava. Due to the inter-specific competition for growth resources, the relative planting time of the compone...

Intensification of agricultural systems in sub-Saharan Africa (SSA) is considered a pre-condition for alleviation of rural poverty. Conservation Agriculture (CA) has been promoted to achieve this goal, based on three principles: minimum tillage, soil surface cover, and diversified crop rotations....

Sub-Saharan Africa needs to produce more food, feed, and fiber to support its growing population and intensification of smallholder agriculture is a crucial component of any strategy towards this goal. Sustainable Intensification (SI) acknowledges that enhanced productivity needs to go hand in ha...

We analyze the adoption of mineral fertilizer in South-Kivu. We model technology adoption as a three-step-process,including awareness, tryout, and adoption; and empirically analyze these steps using cross-sectional farm-household data, and bivariateand Heckman selection probit models. We find tha...
