Abstract: The study developed a model to evaluate efficiencies of Zobo drink processors in Imo State using Data Envelopment Analysis (DEA). Data were collected from 163 Zobo drink processors across 36 markets in the study area and was analyzed under the constant returns to scale (CRTS) and variable returns to scale (VRTS) assumptions. Result showed that Zobo processing was highly profitable with about 44.34% net margin on total revenue generated. Mean economic efficiency scores estimated from the DEA frontier for both CRTS and VRTS were 0.537 and 0.683. Sex, educational level and alternative to income were most statistically significant factors. It was recommended that more male involvements are encouraged in Zobo drink; educated individuals particularly unemployed are advised to engage and create a cliché for themselves through the use of more innovative processing and packaging activities and adopting cost-minimizing input mixes of best-practice to enable them become fully efficient.
