The paper entitled "An economic analysis of energy requirements and input costs for tomato production in Turkey" used energy input output analysis in tomato (industrial type) production and compare it with production costs. The research also pursued to analyze the effect of farm size. As a result of that research, the authors claimed that the better benefit-cost ratio was found on the large farms and it was more successful in economic performance. However, there are some minor and major miscalculations that could, and perhaps should be added to the result section. (C) 2014 Published by Elsevier Ltd.
