The Taoyuan District Agricultural Improvement Station (TYDAIS) was
formerly known as the Taipei Agricultural Test Field and the Hsinchu
Agricultural Test Field. In order to retain its resources and test scopes after the adjustment of local administrative divisions in 1950, the charge of agricultural test fields was changed from county to the Department of Agriculture and Forestry. Due to urbanization, the Taipei Agricultural Improvement Station and the Hsinchu Agricultural Improve Station were merged to the TYDAIS. With the Japanese leaving, the diversified academic system entered the TYDAIS. It was helpful to the restoration and transformation of agriculture. During the Japanese Occupation period, the experiment and research were mainly executing the rice policy of Taiwan Governor general’s Office, but also formed the regional characteristics of vegetables. After the post war, economy transferred from agriculture to industry. Then, the living style changed and there was overproduction of rice, and the TYDAIS tried hard to develop regional delicate crops. Originally, the TYDAIS was responsible for passing the technology to the farmers’ associations, and the farmers’associations would promote the technology to the farmers. However, the farmers’ associations had gradually developed into financial business. That made the research of agricultural extension of TYDAIS become more and more important. And the ways of extension had been continuously innovated and resulted in multiple agricultural extensions.
