Abstract

The paper investigated the level of technical efficiency and its determinants in sweetpotato production in South-East agro-ecological zone of Nigeria. A multistage random sampling technique was used in the selection of states and respondents. Two states, Abia and Enugu were randomly selected from the five states of south-east agro-ecological zone (Abia, Anambra, Ebonyi, Enugu and Imo States). 120 respondents were randomly selected (60 respondents from each state). Data collecting instrument was a well-structured questionnaire. Stochastic frontier production function Original Research Article
