Today, there is a growing interest in the assessment of productivity of agricultural research and development of guidelines on how much national governments and donors should invest in research in Africa. This study pioneers the evaluation of returns to agricultural research in Kenya and uses a production function approach to evaluate the rate of return to investments in maize research from 1955 to 1988. The results indicate that past maize research, extension and seed development programs contributed to increased maize production. The average rate of return to investments in maize research over the 1955-88 period was found to be sixty-eight percent.
