Barley is an important substrate for forage production in winter season of Korea. In this study, field trials were carried out to investigate the effects of harvest time and cultivar on the yield and quality of forage barleys developed in Korea. Four whole crop barley cultivars (Youngyang, Wooho, Yuyeon and Dami) were selected and harvested on five separate growth stages (heading, and intervals of 1, 2, 3, and 4 weeks after heading) in split plot design with three replications. Forage yield and nutritive value were determined. Results from this experiment indicated significant differences due to harvest time and cultivar in dry matter yield and total digestible nutrients (TDN) yield for forage. The interaction between harvest time and cultivar was not significant. The TDN yield trends were increasing with later harvest time due to higher dry matter yield and TDN content. This experiment provides some interesting results with respects to optimum harvest time, feed value and ultimately yield for the different whole crop barley cultivars.

이 연구는 사료용 청보리 전용품종들의 수확 시기별 수량과 품질을 검토하여 적정 수확 및 이용시기를 도출하고자 국립식량과학원 벼맥류부 포장에서 2007년 10월부터 2008년 6월까지 실시하였다. 시험은 수확시기를 주구로 5회 (출수기로부터 7일 간격), 품종을 세구로 4품종 ('영양', '우호', '유연', '다미')을 분할구 배치법 3반복으로 배치하여 실시하였고, 생육특성, 수량 및 사료가치를 조사하였다. 지상부 이삭비율은 출수기 이후 직선적으로 증가
