Cassava yields obtained from farmers' fields in Nigeria during the Collaborative Study of Cassava in Africa (COSCA) survey gave an average root yield of 14.5 t/ha and an average harvest index of about 0.56. The average root yields from both the sub humid and non humid zones were the same but sign...

As a result of their relatively limited access to production resources, it has been variously reported that women obtain lower yields from their individual crop fields than men. Cassava root yields obtained from farmers' fields in three villages of southeast Nigeria were compared using separate o...

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...

Cassava makes an important contribution to improving food security and rural incomes in sub-Saharan Africa, as it is tolerant of drought and poor soil and its cultivation does not require much labour. However, the fresh roots are bulky and perishable and need to be processed before they can be ma...

This paper is based on information collected from about 600 villages in the ten largest cassava-producing countries within the framework of the Collaborative Study of Cassava in Africa (COSCA). The objective of the paper is to show that growth in cassava production in the region will depend more ...
