Abstract
본 연구는 청보리와 월동 콩과작물인 사료용 완두와의 혼파재배를 통해 사료작물로 이용하기에 적합한 작부체계로서의 혼파비율을 구명하고, 조단백질, ADF, NDF 등과 같은 사료가치와 수량을 만족하는 적정한 혼파비율을 비교 분석하기 위하여 실험을 수행하였다. 청보리와 사료용 완두를 혼파재배하였을 때 청보리의 생육특성에서 출수일과 초장은 큰 차이가 없었으며, 청보리의 경수는 사료용 완두의 혼파비율이 높을수록 감소하였지만, 사료용 완두의 개체수는 증가하였다. 청보리의 도복지수는 $0{\sim}3$의 분포로 나타냈는데, 그 중 사료용 완두의 혼파 없이 청보리 20kg/10a만을 파종하였을 때에 도복지수가 3으로 가장 높게 나타났다. 사료용 완두의 생육특성에서 월동률은 모든 파종구에서 90% 이상의 월동률을 보였고, 완두의 초장은 청보리의 파종량에 상관없이 사료용 완두의 파종비율이 높아질수록 증가하는 경향을 보였다. 청보리와 사료용 완두를 혼파재배하였을 때 생초수량은 청보리 14kg/10a 파종구와 20kg/10a 파종구 모두에서 10a당 3,000kg 이상의 수량을 나타냈으며 사료용 완두의 혼파비율이 높아질수록 증가하였으나 건물수량은 생초수량과는 반대로 완두의 혼파비율이 높을수록 감소하는 것으로 나타나 청보리 20kg/10a만을 단일 파종하였을 때 1,266 kg으로 가장 많은 건물수량을 나타냈다. 청보리와 사료용 완두의 혼파 재배했을 때, 조단백질, ADF 및 NDF 함량은 사료용 완두의 혼파비율이 높을수록 높아지는 경향을 보였다. RFV는 청보리만을 14 kg/10a 파종구에서 183.8로 가장 높았으며 사료용 완두의 혼파비율이 높을수록 작아지는 경향을 보였다. 표준화 점수의 크기로 본 가장 적합한 혼파조합은 청보러 20 kg/10a와 사료용 완두 7.5kg/10a 혼파 조합이 2.309로 가장 좋았고, 그 다음으로는 청보리 20kg/10a와 사료용 완두 5.0kg/10a 혼파구가 좋았으며 청보리 14 kg/10a 파종구에서는 청보리 14kg/10a와 사료용 완두 10.0 kg/10a를 혼파한 파종구가 0.354로 좋게 나타난 것으로 유추하여 보면 청보리 20 kg/10a에 사료용 완두를 7.5kg/10a를 파종하는 것이 생산성과 사료가치측면에서 합리적인 혼파비율로 판단되었다. The study was conducted to clarify the mixed seeding rate of whole crop barley with hood type and forage pea for using of forage crops and to compare the forage yield and quality. At a mixed seeding rate between the whole crop barley (WCB) and forage pea, The heading date and plant height of WCB were not a difference according to mixed seeding rate of forage pea. The tillers of the WCB were a decrease and plant of the forage pea were a increase according to increased seeding rate of forage pea. The lodging index of the WCB was a appearance with distribution of $0{\sim}3$, The lodging index of WCB with a 20kg/10a seeding rate of a only WCB without seeding of the forage pea was 3. The overwintering rate of forage pea was a appearance more than 90% at all treatment. The plant height of forage pea was a increase according to increased seeding rate of forage pea at 14 kg/10a and 20 kg/10a plots of WCB. At a mixed seeding between the WCB and forage pea, The fresh weight was a increase according to increased seeding rate of forage pea and was a appearance more than 3,000 kg at all treatment plot. But the dry matter weight was decrease according to increased seeding rates of forage pea. The dry matter weight of 20 kg/10a seeding rate of a only WCB without seeding of the forage pea showed the most amount with 1,266 kg. The crude protein (CP) content was a tendency to increase according to increased seeding rates of forage pea. But, the relative feed value (RFV) was a tendency to decrease according to increased seeding rate of forage pea. The highest RFV was 183.8 at 14 kg/10a seeding rate of a only WCB without seeding of the forage pea. The acid detergent fiber (ADF) and neutral detergent fiber (NDF) were a increase according to increased seeding rate of forage pea at 14 kg/10a and 20 kg/10a plots of WCB. The highest content of ADF and NDF were 23.9% and 46.3% at mixed seeding rate of 20 kg/10a of WCB with 10 kg/10a of forage pea, respectively. The highest sum of standardized score by fresh weight, dry matter weight, CP, ADF, NDF and RFV was 2.309 at mixed seeding rate of 20 kg/10a of WCB with 7.5 kg/10a of forage pea. The optimum mixed seeding rate was a considered judgment in the order of mixed seeding rate of 20 kg/10a of WCB with 7.5 kg/10a of forage pea, mixed seeding rate of 20 kg/10a of WCB with 5.0 kg/10a of forage pea.
