Based on a questionnaire survey conducted in Kagawa Prefecture, this study empirically explores the tendencies of employment management and human resource development in farm organizations. The study shows that introducing permanent workers in their farms, farm managers in Kagawa Prefecture tend to develop a system of command and supervision of workers. With increasing workers, they begin relegating an employee to the charge of production management or supervision of other workers. It is shown that farm managers reaching such managerial levels tend to expand their farm sizes rapidly, and often induce employees to enhance their ability of operational judgment and understand their farming goals or plans. It is also shown that these managers frequently use economic incentives such as salary or position upgrades. With the help of organizational economics theory, this study presents economic explanations on the abovementioned tendencies.
