This study aimed to estimate the economic efficiency of rice and sesame in the crop rotation model of 2 rice crops and 1 sesame crop adopted by farmers in the Mekong River Delta. Cobb - Douglas random marginal profit function analysis of primary data collected from 191 farming households practising this crop rotation model in 2022 showed that the average economic efficiency of farming households estimated in this study was 73.28% in the sesame crop, 66.06% in the winter-spring rice crop, and 60.69% in the fall-winter rice crop. The level of economic efficiency of farming households was also likely to increase if the technical efficiency and allocation efficiency of farming households were optimally improved.
