Abstract
⺠Yield gaps are pervasive in African agriculture, and are large for almost all crops in all regions. ⺠Poor soil fertility is the major biophysical limitation to agricultural production in the continent. ⺠Smallholder farmers are unable to benefit from current yield gains offered by genetic improvement. ⺠Lack of response to inputs of fertiliser and labour in degraded soils constitutes a chronic poverty trap. ⺠A framework for yield gap assessment in Africa smallholder agriculture is proposed.
