Soybeans are an important grains crop with a total cultivation area of 4,442 hectares and an output of 5,955 metric tons. The primary producing areas are Yunlin County, Pingtung County and Hualien County. The nutritional value of these domestically developed varieties is generally higher than that of imported soybeans. To establish the key production technology for organic soybean seed production, , TSIPS has been testing 10 commercial soybean varieties since 2021. Years of research have shown that Kaohsiung No. 10 and Tainan No. 3, 5 and 10 exhibit better fertility performance. Among them, Kaohsiung No. 10 and Tainan No. 10 have better yields and are more suitable for organic production.
TSIPS has stated that powdery mildew, aphids and whiteflies are prone to damage in soybeans organic cultivation. Other common pests and diseases include purple spot, damping off, rust, thrips and leafminers. Soybeans are short-day crops, and experiments have found that black beans bloom later than soybeans. Although black beans have been cultivated in Taiwan for many years, their flowering period remains delayed during spring planting. There is limited research on organic soybean seed production in Taiwan, so TSIPS has continued to invest in research.
TSIPS pointed out that there are a lot of diseases and insect pests in soybean organic cultivation. It is recommended to use organic recommendations for pesticide control, once a week. Increasing the application concentration can cause phytotoxicity on the leaves. Beside regional climate factors can also affect harvests. Avoiding the rainy season which in Linluo area of Pingtung County is from May to early October will reduce the impact of pests, diseases and floods and will help improve seed quality.
TSIPS shoulder the responsibility of supplying seeds according to national policies and is committed to the research and development of seeds and seedlings. In order to implement national agricultural policies, we promote organic soyben cultivation and actively research organic crop production models. Domestic soybeans are produced and consumed locally. Not only do they have short food miles and a low carbon footprint, but they also maintain fresh quality, and retain the unique flavor and aroma of local production. The world has begun to address the issue of net-zero carbon emissions and carbon footprint, giving domestically produced soybeans more competitive advantages.
