Abstract
為建構雜糧種子有機生產模式，本研究透過觀察參試玉米品種於不同肥培條件下的相關表現，藉以評估篩選有機栽培適用之潛在品種。根據肥培試驗結果顯示，分就台南24 號、台南育29 號、台南育30 號及103 等四個玉米參試品種而言，其穗徑、穗長及單穗重表現在肥培處理間並未出現顯著性差異，故於每公頃200.1 公斤之氮素施用量下，應具備有機栽培操作可行性；另與「化肥」處理者相較，「有機1X」處理者具有較高之不合格穗比例。
In order to establish an organic seed production system for grain crops, the potential maize varieties suitable for organic cultivation are evaluated based on the related performances in different fertilization treatments. The results show that there are no significant differences in the performance of ear diameter, ear length, and ear weight between the two fertilization treatments (chemical vs. organic) in the cases of the four varieties tested (Tainan no. 24, Tainan yu no. 29, Tainan yu no. 30, and 103). Therefore, the organic farming is feasible to the varieties mentioned above in the nitrogen supply level (200.1 kg/ha). Besides, the portion of ears eliminated is higher in the fertilization treatment “Organic 1X” compared to the treatment “Chemical”.
