Technical Efficiency of Orange-Fleshed Sweet Potato Root Production in North Central, Nigeria
Main Article Content
Abstract
The paper analysed the technical efficiency and its determinants in orange-fleshed sweet potato root production system in North central, Nigeria. A multistage sampling was used to select 174 OFSP root entrepreneurs in Benue, Nasarawa and Kwara States from whom data were collected on input-output, farmer and farm characteristics with the aid of a structured questionnaire. A Cobb-Douglas stochastic frontier production function was used to analyse the data. The results of the analysis showed that the mean technical efficiency of OFSP root entrepreneur was 76 percent. The study found that the coefficient for household size was negatively assigned and significant at 5 % while age, education, farm experience, extension visits and access to credit were positive and have significant influence on technical efficiency at 5 % level of probability respectively. The study recommends policy decisions that encourage new entrepreneurs to take up OFSP root production and existing ones to remain in business through increased access to education, extension services and credit.
