The experiment was canied out to investigate the effects of cutting frequencies (3, 4 and 5 cuts per year) in relation to fertilization of mineral nitrogen on crude protein yield and the contents of crude protein and acid detergent fibre in orchardgms(Dac
This experiment was undertaken to determine the effect of pasture ages on the total production and seasonal yield trends, botanical composition and forage quality of pasture mixtures. This experiment was conducted at the Livestock Experiment Station, RDA,
본 실험은 전차 확대대어 가는 유휴 논토양에 Reed canarygrass를 재배하였을 때 , 예취빈도와 무기태 질소시비가 건물수량에 미치는 영향을 조사하여, Reed canarygrass의 잠재생산성의 증대를 위한 경제적 이고도 합리적인 예취빈도와 지로시비수준을 추정하고자 하였다. 그 결과를 요약하면 다음과 같다. 1. 예취빈도에 EKfms 예취번초의 상대수량은 3회와 4회 예취구에서 2번초, 5회 예취구에서는 3번초에서 연간 건물수량의 43.1, 3
This experiment was canied out to determine the effects of 3cn1, 6cm, and lOcm of cutting height at harvest on the grass growth, dry matter(DM) yield, and weeds development in reed canarygrass(Phu1uris umndinacea L.) pasttire. The cultivars of reed canary
Birdsfoot trefoil(MO-20)과 tetraploid narrowleaf trefoil(PI302921)및 이들 종간 잡종의 유식물 확력을 건물축적량 광합성율 생장분석 등을 통하여 비교검토하였다. 일반적으로 종간 잡종의 표현형은 그 들 부모의 중간 특성을 나타내었으며, 암호흡, 광합성 및 휴식물생육은 이 들 모계 계통인 MO-20 birdsfoot trefoil과 유사하였다. 중간잡종은 birdsfoot trefoil 보다 빨리 자랐으나 통
The object of this experiment was to suggest the suitable cutting frequency and cutting height for orchardgrass (0G)-red clover(RC) mixtures under the intensive system of short-term pasture utilization. The fields trials were conducted over 3-year period(
본 연구는 휴경지 및 완경사지를 잡약적인 방법으로 초지를 조성하여 단기간(3~6년)에 걸쳐 목초생산성을 증진하는데 자적을 두고 orchardgrass(OG)-red clover(RC) 단순혼파초지의 관리 및 이용체계를 확립하고자 1991년에서 1993년까지 3년간 N-P-K 시비수준 6처리를 두어 (0-0-0-, 50-100-100, 100-150-150, 200-250-250, 300-250-250kg/ha)충남대학교 농과대학 시험포장에서 수행되었던
In order to reduce the problems from the presence of rye crop residues in maize establishment and yield, and also to improve the growth, productivity and nutritive value of rye(Seca1e cereal L.). an experiment was canied out to determine the variety effec
