Abstract

This study employed the input-oriented DEA approach with variable returns to scale assumption to assess the technical, scale, allocative and economic efficiencies of 124 randomly selected tomato farmers under irrigation in the Upper East Region using data of the 2017/2018 production season. The mean technical efficiency and scale efficiency were 97.1 and 97% respectively with many farmers experiencing increasing returns to scale. The mean allocative and economic efficiencies were 42.1 and 41.5% respectively. Farmer’s age, tomato land size, fuel quantity, fertilizer quantity and chemical quantity (herbicide and pesticide) were all significant determinants of technical efficiency scores whereas extension visit, tomato land size and chemical quantity significantly influenced both allocative and economic efficiencies. It is recommended that agro-inputs and fuel usage for tomato farmers under irrigation in the dry season be increased to improve technical efficiency. It is also recommended that extension education to farmers on effective inputs allocation and cost minimization strategies be intensified.
