Expenditure elasticities were estimated for yam and cassava and for seven other food items widely consumed by the people of south-east Nigeria. For all households, the combined elasticity estimate for yam was above unity and almost as high as that of meat. For high expenditure households, however...

Seed yams are an essential input into the Dioscorea yam economy of West Africa. Till date, the agronomic separation of seed yam production from that of ware tuber production for food has not been fully achieved. ‘Milking’ of food tubers to get seed yam continues as a dominant channel of seed yam ...

Yam (Dioscorea sp.) is an extremely important delicacy in Cameroon, with some estimated 45,215 hectares devoted to it, and corresponding annual production of 275,101 metric tons. Production is constrained by several factors including the limited availability and cost of planting material, as well...

A two year trial was conducted at the inland valley of the National Root Crop Research Institute, Umudike during the dry season of 2003/2004 and 2004/2005. The purpose was to evaluate the suitability of five hybrid yam clones of dry season yam production. The yams were planted in manually made ri...
