Cassava, Manihot esculenta Crantz, is a tropical perennial root crop belonging to the family Euphorbiaceae. It is adapted to a wide range of soils and climatic conditions. It is tolerant to drought and can be grown in depleted and marginal soils with little or no commercial inputs such as fertilizers (Mathews et al., 1993). Cassava is an important source of carbohydrates in adverse climatic conditions, a character which promotes it as a major world famine and food security crop (Ihemere et al., 2006). In addition, cassava root starch is a good source of raw material for many processed food, fodder products, pharmaceuticals, paper and textile industries (Balagopalam, 1998).

Total world production is 184 million tons and is distributed as 50% in Africa, 30% in Asia and 20% in Latin America. However, average yield in Ghana, ranges between 7 to 10 t/ha, 26 t/ha in India and 37 t/ha in Thailand (Jain, 2005).
