Due to lack of clear awareness on different sowing methods, majority of Ethiopian smallholders are indifferent of sowing their teff in row or broadcasting method. This study therefore analyzes comparative technical efficiency of teff production under row planting and broadcasting methods and identifies its determinants in southwest Ethiopia, Gurage zone. The study was conducted using cross-sectional data from 276 households. One stage stochastic production frontier model was used for the analysis. The analysis’ results depicted that labor, oxen power, quantity of seed and size of teff cultivated land significantly affects teff productivity under both methods. About 81.3% and 84.8% of the variation in teff output from the frontier was attributed to technical inefficiency in row planting and broadcasting methods, respectively. The mean technical efficiency was 80.4% under row planting and 43.8% under broadcasting; w confirmed that Gurage zone teff producers are more technically efficient under row planting than broadcasting method. Level of education, access to credit, use of improved variety seed, frequency of extension contact, and non-farm income affects technical efficiency positively whereas proximity of teff farm from homestead affects it negatively under both methods. Experience in teff row planting and farm experience affects technical efficiency positively under row planting and broadcasting methods, respectively. Hence, creating further educational opportunities for farmers, providing better credit service, ensuring frequent and more reliable extension contacts, encouraging the use of improved variety seeds, strengthening farmer’s participation on non-farm activities and sowing teff on the nearer farm are vitally important to improve technical efficiency teff crop
