The result depicted that productivity of teff was significantly influenced by the use of seed, fertilizer, and labor. In addition, stochastic production frontier model was used to estimate technical, allocative and economic efficiency level where as OLS regression was used to identify factors affecting inefficiencies level. A Cobb-Douglas production function was employed to assess teff productivity and factors conditioning productivity. Cross sectional data from a random sample of 323 teff producing farmers collected during 2018/19 production season were used for the analysis. This study was undertaken in southwest Ethiopia to assess productivity and technical, allocative and economic efficiencies of teff farmers and identifies factors that determine productivity and inefficiencies. To solve this, improving efficiency of the farmer has received the greatest attention as it is more cost effective than introducing new technologies. The low productivity is mostly attributed to inefficiencies.

Agriculture in Ethiopia is characterized by low productivity for most crops including teff which is gaining prominence as both a food and income crop.
