This study aimed to determine the optimal harvesting time for covered barley to make grain silage, in Honam region of Korea. We harvested six varieties of barley every third day from 24 to 42 days after heading (DAH). The moisture content decreased from 62.4% at 24 DAH to 24% at 42 DAH. The moisture content at 36 DAH was 44.3%; however, moisture content at 39 and 42 DAH was lower than 40%. Yield of covered barley significantly increased from 24 to 42 DAH (p < 0.05). Yield at 36 DAH (557 kg/10a) was not significantly different from that at 39 and 42 DAH (p < 0.05). With respect to the feed value of barley grain silage, the amount of crude fiber and crude ash was different by harvesting time (p < 0.05). However, the amount of crude protein, crude fat, and total digestible nutrients (TDN) from 24 and 42 DAH was not significantly different. The pH of grain silage from 24 to 42 DAH was between 3.8 and 4.2 and it was stable until 36 DAH (p < 0.05). However, the pH of grain silage at 39 and 42 DAH was 5.2 and 5.8, respectively, which was higher than the pH of silage with good fermentation quality. The lactic acid content of barley grain silage from 24 to 42 DAH decreased from 5.5% to 0.5% (p < 0.05). The amount of lactic acid at 36 DAH was higher than that at 39 and 42 DAH (p < 0.05). With respect to moisture content, yield, feed value, and fermentation, the optimal harvesting time for grain silage of covered barley was 36 DAH. This could increase the use efficiency of harvesting machine for barley and reduce the harvesting time gap between whole barley silage and grain silage in Korea. Moreover, using barley grain silage for animal feed could reduce the import of corn.

이 연구는 맥류 곡실발효사료 조제를 위한 적정 수확시기 및 수확시기별 곡실 발효사료의 발효품질을 평가하기 위하여 실시하였다. 그 결과, 알곡의 수분함량은 수확시기가 늦어짐에 따라 감소하는 경향을 보였고, 이삭비율과 천립중은 맥종별 모두 출수 후 일수가 경과됨에 따라 높아지는 경향을 보였다. 알곡수량은 맥종 모두 수확시기가 늦어질수록 유의적으로 증가하는 경향을 보였다(p<0.05). 조단백질 함량은 수확시기가 늦어질수록 맥종 모두 높아지는 경향을 보였고, 조섬유함량은 낮아지는 경향을 보였으며, 조지방과 조회분 함량은 비슷하거나 약간 낮아지는 경향을 보였지만 통계적인 유의성은 없었다. 곡실사료의 발효 전후 사료가치를 비교하여 보면, 일반성분들이 발효를 거친 후 약간 증가되는 경향은 있었지만 유의적인 차이는 나타나지 않았다. 발효품질 면에서는 공시한 맥종 모두 수확시기가 늦어질수록 pH는 높아지고, 젖산함량은 유의적으로 낮아지는 경향을 보였다(p<0.05). 초산함량은 맥종 모두 수확시기에 따른 차이를 나타내지 않았고, 낙산은 검출되지 않았다. 따라서 수량과 발효품질을 고려할 때, 맥류 곡실사료 조제를 위해서는 겉보리과 쌀보리는 출수 후 35일, 밀은 출수 후 40~45일에 수확하는 것이 적당한 것으로 판단된다.

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.

This study was conducted to select suitable rice cultivars for high-quality rice production in silage barley-rice double cropping in Honam plain area by National Institute of Crop Science from 2008 to 2009. Heading dates of all tested cultivars were before the safe heading limit(Aug. 31). Rice yield was superior in "Keunseom", "Hanareum", "Hanmaeum", "Onnuri", "Hopum", "Juan 1", "Dongjin 1", and was little in "Daepyeong", "Hwasin", "Malgeumi", "Chilbo", "Nampyeong", "Hopyeong". Protein content was high in "Hanareum", "Keunseom", "Chilbo", "Nampyeong", and was low in "Hanmaeum", "Dami", "Sindongjin", "Pyeongan", "Samgwang". And head rice ratio was high in "Malgeumi", "Hwanggeumnuri", "Samgwang", and was low in "Keunseom", "Hanareum", "Dami", "Hanmaeum", "Hwasin". In consideration of all the factors, in conclusion, proper cultivars for silage barley-rice double cropping are "Onnuri", "Hwanggeumnuri", "Hopum", "Dongjin 1", "Juan 1".

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.
