The study was based on primary data collected from 82 sweet potato farmers through multistage sampling technique; analysed using descriptive statistics and budgetary techniques. The result revealed that about 90% of the farmers were male with a mean age of 35 years and 22 years of sweet potato farming experience; 87.8% were married and 65% had a household size of 8 persons.

Major production constraints were insufficient land (66%), insufficient labour (51%), pest and diseases (82%) as well as mechanization (98%). Budgetary analysis revealed that, on the average, sampled respondents incurred NG₦41,374.59 on total cost items, earned a revenue of NG₦131,645 and profit of NG₦90,270.41 per production season. Sweet potato production had a rate of return on investment of 2.88. Thus, sweet potato production was found to be a profitable enterprise considering the profit realized by farmers in the study area.
