Yam (Dioscorea spp.) is a tuber crop grown for food security, income generation, and traditional medicine. This crop has a high cultural value for some of the groups growing it. Most of the production comes from West Africa where the increased demand has been covered by enlarging cultivated surfa...

The challenge of improving soil fertility in yam cropping systems of West Africa
White Guinea yam (
Dioscorea rotundata
Poir.) is
an important staple to millions of people in West Africa.
Obtaining good quality planting material for yam cultivation
is a major challenge. Multiplication ratios are low, and seed
tubers are prone to contamination with pests and pathogens in
the t...

Improved propagation methods to raise the productivity of yam (Dioscorea rotundata Poir.)
New seed yam systems from minisetts, minitubers and vine cuttings have been developed for yam production to supplant the traditional systems, which have proven inefficient and costly. The new techniques provide producers in tropical countries with the opportunity to minimize production costs, red...

Economic analysis of seed yam production systems in Nigeria
Yams are staples in West Africa. They are propagated from tubers in an informal seed system. This encourages a build-up of diseases, and necessitates the rapid development of a formal seed system where certified seeds are functional. Although few reports exist on the use of meristem culture to ge...
