Profit Efficiency Of Farmers\' Sustained Use Of Improved Cassava Varieties In Imo State, Nigeria.

Profit efficiency of farmers\' sustained use of improved cassava varieties in Imo State was estimated using stochastic translog profit frontier model. The mean level of profit efficiency was 81.9% with a range of 51.27% - 98.35%. Mean farm profit was N146, 309.00 per hectare. Determinants of level of sustained use of improved cassava varieties were taste, yield, garri quality, harvesting ease, early maturity, tubs size, stand establishment, root storability, water content and availability of cuttings. Sustained use of improved cassava varieties would be practiced by more farmers in Imo State if the factors effecting sustained use of improved varieties are adequately considered by the research institutes at the point of development of new cassava varieties.
