This study was carried out to determine the effect of mixed pasture using domestic varieties orchardgrass ‘Kodione’ and tall fescue ‘Purumi’ on forage yields and botanical composition from 2013 to 2015 in middle region of Korea. The following mixed pastures were used in this study: treatment A (orchardgrass oriented mixture with imported varieties), treatment B (orchardgrass oriented mixture), treatment C (orchardgrass and tall fescue oriented mixture), treatment D (tall fescue oriented mixture), treatment E (tall fescue oriented mixture without orchardgrass), treatment F (only orchardgrass), and treatment G (only tall fescue). In botanical compositions at last cutting time in 2015, treatment A had orchardgrass at 7.1%, tall fescue at 47.9%, kentucky bluegrass at 15.2% and white clover at 25%. Meanwhile, treatment B had orchardgrass at 25.9%, tall fescue at 47.0%, kentucky bluegrass at 4.9% and white clover at 18.3%. Consequentially, in botanical composition from 2014 to 2015, treatment A was changed more compare to other treatments B, C, D and E. The average of dry matter (DM) yield for 2 years of treatment E (18,369 kg/ha) was the highest among the seven treatments, but there was no significant difference among other treatments except treatment A (p>0.05). The crude protein (CP) and in vitro dry matter digestibility (IVDMD) of treatment A were 14.5% and 74.8%, and treatment E were 14.1% and 73.0%, respectively. The content of neutral detergent fiber (NDF) and acid detergent fiber (ADF) were lower in treatment E and A than other treatments, and treatment E showed high content of total digestible nutrient (TDN). Therefore, tall fescue oriented mixture using domestic tall fescue variety Purumi had good forage productivity, quality and botanical composition in middle region of Korea for the establishment of grassland.

본 연구는 기호성이 높으며 여름철 고온에 강한 새로운 tall fescue 품종을 구명하기 위해 초지조성 후 5년째인 1997년 방목기간 동안에 북제주군 한림읍 이시돌 목장에서 홀스타인 육성우(방목개시시 체중 110kg 내외)를 이용하여 구당 250(50mx50m)의 면적에서 2처리(T1 = Fawn tall fescue + orchardgrass + perennial ryegrass + white clover, T2 = Roa tall fescue )

The objectives of this research are to determine the seasonal and varietal differences of total digestible nutrients(TDN) and in vitro dry matter digestibility(1VDMD) of tall fescue grown in Takwalyon areas, based on the data of preceding paper(Lee et al.

This experiment was undertaken to study the relationship between dry weight of plant(DW) and yield components. varietal differences in seasonal production at each of three cutting. and to classiQ them into some patterns of seasonal production in tall fesc

대관령 지역에서 Tall fescue 9개 품종을 공시하여 가을철 예취시기에 따른 2번초의 수량구성 요소와 개체중의 변화를 검토하여 이 지역의 환경조건에 적응성이 높은 품종을 선발하여고 하였으며, 얻어진 결과를 요약하면 다음과 같다. 1. 2번초에서 개체당 경수가 많은 품종(Barcel, Forager)이 개체중도 무거워서 이지역의 환경조건에 적응성이 높은 품종이라고 생각되었다. 2. 가을철 예취시기에 따른 2번초의 개체당 경수는 개체중과 0.1%의 유

대관령지역의 영년초지에서 재배되는 Tall fescue 품종의 월동성을 상대경수출현율당 개체중으로 평가하였다. 1 상대경수출현율당 개체중에 의하여 Tall fescue 품종을 2품종군으로 분류하였다. 즉 상대경수출현율당 개체중이 2.0이상에는 Forager와 Fuego의 2품종이, 그리고 2.0 미만에는 Barcel, Barvetia, Demeter. Enforcer, Johnstone, Safe 그리고 Stef의 7품종이 포함되었다. 2. 상대경수출현
