중부지역 논에서 이탈리안 라이그라스와 하계 사료작물을 연계한 작부체계 연구 Study on the Forage Cropping System of Italian Ryegrass and Summer Forage Crops at Paddy Field in Middle Region of Korea원문보기
본 시험은 중부지역 논에서 동계 사료작물인 이탈리안 라이그라스와 하계 사료작물을 연계하여 연간 생산성 및 사료가치를 비교하기 위하여 수행하였다. 동계 사료작물인 이탈리안 라이그라스는 코윈어리 품종을 사용하였고, 하계 사료작물로 사료용 벼(영우)와 사료용 피(제주)를 이용하였다. 각각의 작물은 표준재배법을 이용하여 재배하였다. 이탈리안 라이그라스의 평균 초장은 90.6 cm, DM 수량은 7,681 kg/ha, CP 함량은 9.2%, TDN 함량은 63.8%였고, 하계 사료작물에 따른 차이는 나타나지 않았다. 하계 사료작물의 초장은 사료용 피가 사료용 벼 보다 높았고, 유의성이 인정되었다. 하계 사료작물의 DM, CP 그리고 TDN 수량은 사료용 벼가 사료용 피 보다 유의적으로 높게 나타났다. 하계 사료작물의 사료가치 또한 사료용 벼가 사료용 피보다 높게 평가되었다. 이상의 결과를 종합하여 볼 때 중부지역 논에서 사료작물 이모작 재배 시 동계 사료작물인 이탈리안 라이그라스와 연계한 하계 사료작물로써 수량성과 사료가치가 높았던 사료용 벼가 활용성이 높을 것으로 판단된다. 또한 노동력 절감 및 안전성 재배 측면에서 볼 때 사료용 피도 활용 가능성이 있을 것으로 사료된다.

This study was evaluated to compare annual productivity and feed value of Italian ryegrass and summer forage crops at paddy field in middle region of Korea. Italian ryegrass (Kowinearly) was used as winter forage crop, and forage rice (Youngwoo) and barnyard millet (Jeju) were used as summer forage crops. Each crop was cultivated using the standard forage cultivation method. The plant height, dry matter yield, crude protein content, and total digestible nutrient content of Italian ryegrass were 90.6 cm, 7,681 kg/ha, 9.2%, and 63.8%, respectively, and it was no significant difference by summer forage crops (p>0.05). The plant height of summer forage crops was the higher in barnyard millet than in forage rice (p<0.05). The dry matter, crude protein, and total digestible nutrient yields of summer forage crops were the higher in forage rice than in barnyard millet (p<0.05). Also, the feed value of summer forage crops was higher in forage rice than in barnyard millet. In conclusion, the combination of Italian ryegrass-forage rice was the most effective cropping system for annual forage production with high-yield and high-feed value, and it was considered the combination of Italian ryegrass-barnyard millet was good cropping system for annual forage production through reducing labor and cultivating stable at paddy field in middle region of Korea.
