In this study total factor productivity, technical efficiency and technological changes of cereals with and without agricultural researches was analyzed by Malmquist method. Results indicated that growth of total factor productivity for cereals had an increasing trend. When the research impact was included, this trend was decreased due to ineffectiveness of research from the viewpoint of result transmission to farm level and outlast of the researches results for the trust of transmission consequences. Technical efficiency has less growth compared to technological changes and therefore its impact on productivity changes is less. According to the results, proper management can be exerted to increase the research productivity.
