There are extensive numbers of studies focusing on efficiency as a means of fostering agriculture production. The article reviews the literature devoted to technical efficiency analysis in various countries and its applications to agricultural production. The studies reviewed focused particularly on rice and wheat making them the most studied agricultural product by researchers. The review of efficiency analysis shows that agricultural output can be increased without additional inputs with given existing technology. Technical efficiency of agricultural crops like wheat, paddy, cotton etc grown in different countries ofthe world like India, Pakistan, Ethopia, Srilanka were reviewed and it was found that except for farm size, the variables like farmer education and experience, contacts with extension personnel and access to credit, tend to have a positive and statistically significant impact on technical efficiency. 收起
