초록

본 시험은 우리나라 중부지역(충남 금산, 해발 250m)에서 유기물 시용과 및 혼파조합에 따른 신규조성 초지의 생산성 변화를 평가하기 위하여 수행하였다. 총 6개의 처리 (오차드 그라스 위주, 티머시 위주 그리고 톨페스큐 위주의 혼파 초지에 유기질 비료의 시용 유무)를 두고 2014년 가을에 조성하여 2015년부터 2016년까지 조사하였다. 초장은 오차드그라스 위주 혼파조합에서 길었으며 2차 수확시는 오차드그라스 위주 및 톨페스큐 위주의 혼파조합에서 길었다. 건물함량은 대체적으로 처리간에 유의적인 차이가 없었다(P<0.05). 식생은 1차 수확시 오차드그라스 위주 혼파조합에서 잡초의 비율이 높았으며 3차 수확시에는 모든 처리구에서 두과목초가 사라졌다. 생초 및 건물수량은 1년차보다는 2년차에서 더 높게 나타났다. 또한 1년차에 유기물을 시용한 오차드그라스 위주 혼파조합에서 유의적으로 높았으며(P<0.05), 2년차에서는 유기물을 시용한 톨페스큐 위주 혼파조합에서 가장 높게 나타났다. 조단백질 함량은 톨페스큐 혼파조합에서 높게 나타났으며 티머시 위주 혼파조합에서 ADF 및 NDF 함량이 낮았고 소화율은 높았다. 조성 2년차에서는 2회 및 4회 예취시 목초의 사료가치가 높게 나타났으며 평균 RFV값도 4차에서 가장 높았다. 이상의 결과를 종합하여 볼 때 중부지역 구릉지 초지 조성시 생산성 면에서는 유기물을 시용한 오차드그라스와 톨페스큐 위주 혼파조합이 우수하였으며 사료가치적 측면에서는 티머시 위주 혼파조합이 우수한 것으로 나타났다.

This experiment was carried out to determine the effect of organic fertilizer and seed mixture on productivity, botanical composition and forage quality in middle areas(Geumsan, 250m sea level) pasture. Total six experimental pastures (orchardgrass, timothy and tall fescue based seed mixture and with or without organic fertilizer) were established in autumn, 2014 and evaluated productivity and agronomic characteristics from 2015 to 2016. Plant heigh was higher in orchardgrass based mixture and orchardgrass and tall fescue based mixture were higher in $2^{nd}$ harvest. There was not found the significant difference among treatment(P<0.05) in dry matter (DM) content. Botanical composition in $1^{st}$ harvest was higher weed portion in orchardgrass based mixture and legumes was disappeared at $3^{rd}$ harvest in all treatments. Fresh and dry matter yield was higher in $2^{nd}$ year than $1^{st}$ year. In $1^{st}$ year, orchardgrass based mixture with organic fertilizer plot was the highest(P<0.05) DM yield, but tall fescue based mixture with organic fertilizer was the highest in $2^{nd}$ year. Content of crude protein (CP) was the highest in tall fescue based mixture and Timothy based mixture showed low in ADF (acid detergent fiber) and NDF (neutral detergent fiber) content. But the content if in virto dry matter digestibility was higher than others. In $2^{nd}$ year, the nutritive value of $2^{nd}$ and $4^{th}$ harvested grasses were higher and average RFV (relative feed value) value was the highest at $4^{th}$ harvest. According to this result, orchardgrass and tall fescue based mixture would be recommendable for farm who considering productivity and timothy based mixture would be recommendable for considering forage quality in middle areas of Korea.
