This study examined the effects of socio-economic characteristics of cassava producers’ on their output in Obio/Akpor Local Government Area of Rivers State, Nigeria. A multi-stage sampling technique was used in the selection of 80 respondents. The data obtained were analysed with percentages and multiple regression analysis. The result obtained revealed that the mean age of cassava farmers was 44 years and their mean farm size was (0.1496 ha) while the double logged multiple regression result depicted that farm size (0.191ha) (P<0.05) and labour (0.361) (P<0.01) were statistically significant in increasing cassava output and majority of the farmers (100%) practices manual farming. The coefficient of determination R2 (55%) shows that there was significant relationship between output and the selected explanatory variables of cassava producers. It is therefore recommended that government should grant loan to farmers in order to boost their production and enhance their food security.
