This study analyzed farmland value systems and productivity of cassava in ecologically vulnerable areas of Imo State, Nigeria. The study estimated productivity of farmland systems and factors affecting them, and farmland suitability. Data were collected with questionnaire from 360 randomly selected cassava farmers and analyzed using descriptive statistics, suitability model, productivity model, and multiple regression techniques. Farmland suitability index ranges from 0.107 to 0.712 with a mean of 0.493. Majority (62.4%) of the cassava farmers cultivate on non-suitable farmlands, 33.7% of them cultivate on marginally suitable farmlands, while 3.9% of them cultivate on suitable farmlands. Productivity of farmland were 1.38, 2.00 and 3.16 for non-suitable, marginally suitable and suitable value systems respectively, indicating that marginally suitable and suitable farmlands were higher in productivity than non-suitable farmlands. Land rent, quantity of fertilizer, and household size have significant and negative effect on non-suitable farmland productivity. Farm size, land rent, fertilizer applied, education and extension have significant effect on marginally suitable farmlands productivity. Farm size, fertilizer, farming experience and household size significantly affect suitable farmland productivity. Farmers cultivating suitable farmlands should increase their cassava output and improve their farm income through allocation of more production resources to cassava production in an optimal manner.
