忠州地方에 있어서 國內 및 導入 Silage 用 옥수수의 生産性과 地域適應性에 關한 硏究 = Studies on the Productivity and Adaptability of Foreign or Domestic Corn for Silage in Chungju Areas

국문 초록 (Abstract)

本 實驗은 導入 및 國産 옥수수 品種比較를 통해 忠州地에 적합한 Silage용 옥수수 品種의 選拔과 地域 適應性을 규명하고자 遂行했던 바 그 결과를 要約하면 다음과 같다.
1. 着穗高는 모든 品種이 杆長의 중간 이하에 위치하였으며 葉數는 中ㆍ晩生種인 P3160과 DK729가 각각 15.4와 13.7로 가장 많았다.
2. 倒伏, 缺株 및 錄色度 유지는 P3160과 DK729가 良好했다.
3. 總　物收量은 P3160과 DK729가 他品種들에 비해 有意的(p>0.05)으로 많았으며 乾物암이삭收量도 같은 京鄕을 나타냈다.
4. 部位別 乾物重 比率　 있어서는 거의 모든 品種이 암이삭比率이 높았다.
5. 葉面積과 個體 生長速度, 그리고 TDN 收量에 있어서는 모두 P360과 DK729 및 G 4743이 높았다.
6. 以上의 結果로 볼 때 이곳 忠州地方에서 Silage용으로 옥수를 栽培時에는 P360과 DK729 및 G 4743 品種을 선책하는 것이 바람직할 것으로 사료된다

다국어 초록 (Multilingual Abstract)

This experiment was carried out in order to select cultivar of corn for silage and examine closely regional adaptability in Chungju areas by making use of domestic, foreign recommended cultivars and imported new cultivars to investigate of regional adaptability of existing recommended cultivars and new importing cultivars continuosly. The results obtained are summarized as follows:
1. The position of ear was below half of stalk length in all cultivars, and in number of leaf, P 3160 and DK 729 were the most of all cultivars by 15.4 and 13.7 respectively.
2. Lodging, missing hill and greeness of P 3160 and DK 729 were better than those of the other cultivars.
3. In total dry matter yield, o3160 and DK 729 were significantly(p<0.05)the highest of all cultivars, and also dry matter ear yield showed the same tendency.
4. In total dry matter weight ratio of each part, ration of ear in all cultivars were mostly high.
5. In left area, crop growth rate and TDN yield, p 3160, DK 729 and Gj4743 were higher than those of the other cultivars.
6. As mentioned above, selection of the P 3160, DK 729 and G 4743 were though desirable as cultivated of corn for silage in this Chungju areas
