  • Abstract:

This study examined efficiency and profitability of sweet potato production in north central and northwestern Nigeria as a potential for enhancing food security. Primary sources of the data were gathered by field surveys in 2016/2017 farming season through questionnaire and interview. A multistage sampling procedure was used to select 200 respondents comprising 100 farmers each from kwara and katsina states. Data collected were analyzed using descriptive statistics, net farm income and stochastic frontier functions. The results revealed that area devoted to sweet potato farming, level of education, access to credit, and farming experience were found to be higher in kwara state. However, household size, family labour involvement in farming and quantity of fertilizer used per ha was found to be higher in katsina state compared to kwara state. Sweet potato production was profitable in both states with an average return of N2.35and N1.66on every N1 invested in kwara and katsina states respectively. The results of the stochastic frontier model showed that there are significant differences in the technical and allocative efficiency of both kwara and katsina sweet potato farmers, and the pooled data in the study area. The pooled technical efficiency index of the farmers is directly proportional to level of education and years of sweet potato production. This suggests that farmers with more years of experience and education are likely to have higher yields whichare sine quo non to food accessibility and affordability among households. Farmers are encouraged to increase the hectarage of sweet potato production to increase profit. The sustainable increased in output could be achieved if farmers adopt a new techniques and improved their technical efficiency through training and workshops on input acquisition, inputs combinations and utilization as ample opportunity still exist to move closer to frontier.
