중북부지역 답리작 보리담근먹이 조제이용 연구

The yield performance and nutrient quality of barley for pellets making from whole crop material were discussed during 1993-1994. Barley (cv. Olbori) was grown on paddy land after rice cutivation and was harvested at early stage of physiological maturity.

This study was aimed to grow organic forage as a prime requirement for organic Hanwoo cattle production over a period of 3 years (2012~2015) in Gyeongbuk region, Korea through mixed cropping of winter fodder barley with legume and application of fermented cattle manure. The effect of barley-legume mixed cropping and application of different levels of fermented cattle manure was studied on forage productivity of whole-crop barley (WCB) and evaluation of feeding capacity of Korean native cattle (Hanwoo) per unit area. The collected data was analyzed using SAS 9.3 software. Barley-legume mixed cropping increased (P< 0.05) yields of dry matter (DM), crude protein (CP) and total digestible nutrients (TDN) as compared to those of sole WCB as monoculture. Similarly, acid detergent fiber (ADF) contents and relative feed value (RFV) were also higher (P<0.05) in barley-legume mixed sowing forage compared with those of sole WCB as monoculture. In case of manure application, yields of DM, CP and TDN were also found (P<0.05) highest in 100~150 ㎏ N/㏊. However, varying cattle manure levels did not influence (P>0.05) CP and neutral detergent fiber (NDF) contents. In response to increasing nitrogen application level, ADF content increased (P<0.05) but TDN content and RFV decreased (P<0.05). The Barley-legume mixed sowing and increasing application levels of fermented cattle manure also significantly enhanced (P<0.05) feeding capacity of organic Hanwoo (head/ha) having 450 kg body weight with 400 g of daily gain. Findings of present study indicated that barley-legume biculture not only cut nitrogen application level of fermented cattle manure by over 50 kg per ha but also increased their feed value and productivity of forage as compared to WCB monoculture. This would be contribution to the diversity of forage resources as well as production of organic animal product by creating low cost and high quality organic forage.

This study was conducted to investigate the mixed seeding of 5 forage barley varieties (youngyang, yuyeon, dami, wooho, soman) with 1 malting barley variety (hopum). Yield of the mixed seeding was compared with each single seeding and variety combinations. Yield of mixed seeding combination was higher than each single seeding. In mixed seeding of ‘Youngyang’ and ‘Hopum’ (50% and 50% ratio), ‘Yuyeon’ and ‘Hopum’ (70% and 30% ratio), ‘Dami’ and ‘Hopum’ (50% and 50% ratio), ‘Wooho’ and ‘Hopum’ (50% and 50% ratio) were higher yield of dry weight than yield of other mixed ratios. Most of all, mixed seeding of ‘Dami’ and ‘Hopum’ were high yield mixed seeding (ratios of 50% each other). In generally, the yields of barley mixed seeding with malting barley ‘Hopum’ were high production. The forage quality of mixed seeding combination was higher than any each single seeding. ‘Youyeon’ 50% and ‘Hopum’ 50% ratio was more higher

‘조미’는 답리작 적응 내재해 다수성 청보리 품종육성을 목표로 1999년 내재해성으로 총체적성이 우수한 ‘수원337호’를 모본으로 하고, 도복에 강한 ‘수원355호’를 부본으로 교배하여 육성 선발된 ‘익산438호’로 전국 7개소에서 2008년부터 2010년까지 지역적응시험을 거쳐 2010년에 육성되었다. ‘조미’는 직립 초형으로 파성은 Ⅰ정도이고, 잎은 녹색이며, 잎귀가 없는 무엽이 품종으로 가축기호성이 높다. 초장은 90㎝이고, m2당 경수는 846개로 표준품종인 ‘영양’보다 194개 많은 다얼성이며, 엽신 비율이 높다.답리작에서 출수기는 4월 23일로 ‘영양’보다 3일 빠르고, 황숙기는 5월 25일로 1일 빠른 조숙종이다. 내한성은 ‘영양’보다 다소 강하였으며, 흰가루병에는 감수성을 보였지만 보리호위축병에 저항성을 나타냈다. 건물수량은 전작에서 15.7톤/ha ‘영양’과 같았으나 답리작에서 10.3톤/ha으로 ‘영양보다 5% 적었다. 조사료 품질은 조단백질 함량이 8.3%로 ‘영양’에 비해 높았으며, ADF는 26.2%, NDF는 48.3%로 ‘영양’보다 낮았으나 TDN이 68.2%로 ‘영양’보다 다소 높고, 사일리지 등급은 II 등급으로 양호하였다.

This experiment was conducted to obtain basic a information on feed value and fermentative quality of whole crop barley with different harvesting time and making method. As a result, in case of feed value, crude protein, NDF and ADF content were decreased with late harvest, but TDN was increased. In the silage, the results were similar and these patterns showed the same before and after the silage making. Thus, there was no significantly difference in bale and chopper. In case of fermentative quality, pH of the silages showed increasing with late harvesting time but the contents of organic acid did lower, and those tendencies were the same in both bale and chopper condition. But the lactic acid content were approximately 23 percent higher in chopped condition. In conclusion, ensiling at yellow ripe stage is better than other stages, chopped ensiling could improve fermentation quality.

‘Youhan’ (Hordeum vulgare L.), a new whole crop barley cultivar, was developed by the breeding team at the Department of Rice and Winter Cereal Crop, National Institute of Crop Science, RDA in 2012. ‘Youhan’ has the growth habit of III, light green and middle size leaf, hooded and lax-type spikes. The cultivar showed 107 cm of culm length, 641 spikes per m2. Heading date of ‘Youhan’ was May 1, one day later than that of check cultivar ‘Yuyeon’ in upland, and 2 days earlier than that of check in paddy field. Maturing time was similar to check cultivar ‘Yuyeon’ as June 4 in upland and May 31 in paddy field. ‘Youhan’ also showed better winter hardiness, the resistance to lodging and disease than those of check cultivar. The average forage dry matter yield in the regional yield trial was about 12.6 and 12.0 ton ha-1 in upland and paddy field, respectively, which were 6%, 5% higher than that of the check. It also showed 7.3% of crude protein, 26.8% of ADF(Acid Detergent Fiber), 47.8% of NDF(Neutral Detergent Fiber), and 67.7% of TDN(Total Digestible Nutrients), including higher grade of silage quality for whole crop barley. Fall sowing cropping of ‘Youhan’ is recommended only in areas where average daily minimum mean temperatures in January are higher than －8°C, and it should not be cultivated in mountain areas of Korea.

A field experiment was conducted to evaluate the varietal variation of Se concentration and to determine the effects of selenium foliar applications on the productivity and agronomic characteristics of the whole-crop barleys. Se fertilizer was foliar applied at five levels(0, 50, 100, 200, 400 ppm) and two forms (sodium selenite and sodium selenate solution) at stem elongation stage, the middle of April. Cultivar effects on whole-plant Se contents were small and not significant. Regardless treatments, there were no remarkable effects on dry matter yield and forage quality of whole crop barleys. Se contents of plant was higher in selenate application by 3~10 times than selenite. In selenate treatments, as Se levels were raised from 50 ppm to 400ppm the Se contents were increased from 331ppb to 3433ppb and Se contents were positively correlated with the rate of Se application levels. Selenium(Se) is an essential nutritional trace element, which is needed for growth and reproduction in all living animals. But the line between the requirement and harmfulness of Se is narrow since selenium is a highly toxic element. The level of Se in feeds of plant varies depending on plant species, growing season and soil which the plants grow on. Because of low concentration of Se in domestic soils, the selenium availability to plants is limited and it is necessary to supplement feed with selenium. Generally organic Se is less toxic and more efficiently utilized than inorganic Se. Under the condition that antibiotics use in feed are prohibited, selenium enriched whole-crop barley can be one way to improve animal health.

‘Jungmo2502’ awnless barley line (Hordeum vulgare L.) developed at National Institute of Crop Science, RDA in 2011. The Jungmo2502 derived from three-way cross between Millyang100 and F1 (Samheung/Suwon300) in 2000. Subsequent generation were handled by the bulk method in a pedigree selection program. A promising line showed high yield as well as lodging resistance in the yield trial tested at Iksan in 2007 to 2008, designated as Iksan 448. The line in the regional yield trials(RYT) tested in seven locations around Korea for three years from 2009 to 2011. The Jungmo2502 is carrying the growth habit of Ⅳ, green leaf and stem similar to the check cultivar ′Youngyang′. Its heading date was May 3, and maturing time was May 30 in paddy field, which was 3 days later respectively than check cultivar. It was 98 cm of culm length, 607 spikes per m2 and showed more rate of leaf blade, winter hardiness, and resistance to BaYMV than the check cultivar. Average dry matter yield was similar with the check cultivar in paddy field (about 11 ton ha-1). It also showed good qualities as 8.7% of crude protein, 21.9% of ADF (acid detergent fiber), 40.7% of NDF (neutral detergent fiber), and 71.6% of TDN (total digestible nutrients), including high grade of silage for whole crop barley.

A new whole crop silage barley cultivar, “oungyang” was developed from the cross between “unong and Milyang55 at the Yeongnam Agricultural Research Institute (YARI) in 2002. An elite line, YB3882-3B-17-1-3-1, was selected in 1999 and designated as “ilyang111” It showed good agronomic performance in the regional adaptation yield trials (RYT) from 2000 to 2002 and was released by the name of “oungyang”with higher yield and better animal feed quality than that of Olbori. The average heading and maturing dates of Youngyang were May 2 and June 6, which were late by 2 & 1 days than those of Olbori, respectively, in Suwon. Youngyang had longer culm length, 83cm but it had lesser spikes per m2 637 than that of Olbori, respectively, in RYT from 2000 to 2002. The rate of leaf sheath/whole length (culm+leaf) and the rate of the grains/ whole crop weight was similar to Olbori. It showed resistance to BaYMV at the regions of Naju, Jinju, Milyang andt Iksan. however, the response of Youngyang to other environmental stresses (tolerance of cold and wet) was similar to Olbori. The dried whole crop yield potential of Youngyang in the RYT was about 11.67 MT/ha in paddy fields which was about 18% higher than that of Olbori. The grain yield potential was 6.32 MT/ha in paddy fields which was about 5% higher than that of Olbori. Youngyang had lower rate of shattering, higher content of protein and NDF, lower ADF and TDN, and better quality of silage than those of Olbori.
