초록

본 시험은 충남대학교 농과대학 초지시험포장에 1995년 9월부터 1998년 5월까지 속간교잡종인 Festulolium braunii (품종, Paulita)의 국내 보급가능성을 타진하고자 3처리의 혼파유형 (1) Festulolium braunii (FB, 파종비율 50%)+orchardgrass(OG, 50%), (2) Festulolium braunii (FB, 80%)+red clover (RC, 20%) 및 (3) Festulolium braunii (FB, 20%)+orchardgrass(OG, 50%)+tall fescue(TF, 20%)+white clover(WC, 10%)을 두어 난괴법 4반복으로 건물수량과 품질을 비교하였으며 얻어진 결과는 다음과 같다. 건물수량은 처리간에 유의적인 차이는 없었으나 FB+RC 초지가 다른 혼파유형에 비하여 약간 많았다. CP 함량은 FB+RC 초지가 다른 혼파유형에 비하여 높았으며(P<0.05), 반대로 NDF와 ADF 함량은 다른 혼파유형에 비하여 오히려 낮은 결과를 가져왔다(P<0.05). CP와 DDM 수량은 FB+RC 초지가 다른 혼파유형에 비하여 높은 결과를 나타내었다(P<0.05). 97년의 마지막 예취시기에 조사한 식생비율은 모든 혼파유형에서 FB의 식생비율이 51~58%로 높게 유지되었다. 이상의 결과를 종합할 때 FB는 다른 초종과 혼파가능성은 충분하다고 하겠으며, 그 중 RC와 혼파하는 것이 가장 좋은 결과를 얻었다.

This study was conducted to evaluate the dry matter yield and quality of mixture types with Festulolium braunii (Festuca pratensis Huds. ${\times}$ Lolium multiflorum Lam.) as a forage sources. The experiment was arranged in a randomized block design with three mixture types: (1) Festulolium braunii (seeding rate, FB 50%)+orchardgrass (OG 50%), (2) Festulolium braunii (FB 80%)+red clover(RC 20%), and (3) Festulolium braunii (FB 20%)+orchardgrass (OG 50%)+tall fescue(TF 20%)+white clover (WC 10%) and four replications. This study carried out from Sep. 1995 to May 1998 at Chungnam University. Throughout this experiment, the dry matter yields and forage quality were observed. The DM yield of FB+RC mixtures was higher than that of other mixture types, but there were no significant difference among mixture types. The FB+RC mixtures was higher than the other mixture types in the CP content(P<0.05). However, the NDF and ADF content of FB+RC mixtures were significantly lower than those of other mixture types(P<0.05). The CP and DDM yields of FB+RC mixtures were higher than those of other mixture types(P<0.05). In addition, the FB percentage of total herbage was ranged from 51% to 58% in all mixture types at the last cutting time in 1997. Based on the results mentioned above, it appears that FB has enough of possibility in mixture with other grasses, especially good mixed with RC.
