1.1 Background of the Study
Cassava (Manihot spp) is believed to have originated from Brazil and was introduced into West Africa countries by the Portuguese (Antonio, 2002). Benue and Kogi States in the north central zone of Nigeria are the largest producers of cassava in the country (IITA, 2004). Cassava’s comparative advantage compared with other food crops lies in its efficient production of cheap food energy. In addition, cassava is available all year round as well as tolerant to extreme conditions. These qualities contribute in alleviating African food crises (Nweke, Dixon, Asiedu and Folayan, 1994). This accounts for why Philip (2005) referred to cassava as the “famine security crop”.
