The effects of liquid pig manure (LPM) on the yield and nutrient supply of green manure crops, such as hairy vetch alone and hairy vetch + rye mixture, were investigated. We used three treatments: no-fertilizer (NF); LPM, $4.0t10a^{-1}$ ($N-P_2O_5-K_2O=4.0-0.024-4.0kg10a^{-1}$); and chemical fertilizer (CF; $N-P_2O_5-K_2O=4.0-0-4.0kg10a^{-1}$). The green manure crops, namely, Vicia villosa Roth. (hairy vetch) and Secale cereale L. (rye). were sown on March 11 and harvested on June 24, 2014. Yield of green manure crops significantly increased in hairy vetch + rye mixture plot compared with the hairy vetch alone plot. In hairy vetch alone plot, yield of green manure crops was increased by application of LPM and CF, but there were no significant differences. Yield of green manure crops in hairy vetch + rye fresh mixture plot significantly increased by the LPM and CF treatments, but no difference was noted between the LPM and CF treatments. Nitrogen supply by the green manure crops was higher in hairy vetch + rye mixture plot than hairy vetch alone plot. However, there was no significant difference. Phosphorus and potassium supply significantly increased in hairy vetch + rye mixture plot compared with hairy vetch alone plot. By treating LPM and CF, the nitrogen, phosphorus and potassium supply were higher than those in no fertilizer. In conclusion, LPM could replace CF. When planting green manure crops, the hairy vetch + rye mixture was more effective than hairy vetch alone to effectively use green manure crops.

'중모2509'는 국내의 재배환경에 어울리고, 조사료용이지만 종자가 균일하여 식용으로의 활용이 가능한 국내 최초의 자식계 호밀 품종이다. 품종은 1999년도에 자가불화합성으로 타식성 품종인 '올호밀'을 모본으로 하고, 자가화합성으로 자식계인 'Synthetic II'을 부본으로 인공교배하여 만들었다. '중모2509'는 중간 크기의 녹색이고 다소 긴 잎, 황백색 줄기와 작고 황갈색인 종실을 가졌다. '중모2509'는 출수기가 4월 23일로 기존의 타가 수정 품종인 '곡우'의 4월 18일보다 5일 늦지만, 내한성·습해·병해는 대등하였으며, 도복은 강하였다. 건물수량은 ha당 7.60톤(생초수량 35.2톤)이고, 종실수량이 2.08톤으로 '곡우'보다 적었다. 그러나 자식에 의해 종자가 생산된 자식률은 56 %로, 자식에 의해 임실이 되지 않은 '곡우'와 대조되었다. '중모2509'는 조단백질 함량(9.4 %), 가소화영양소총량(55.7 %)이 표준품종인 '곡우'(8.0 %, 55.0 %) 보다 높았다. '중모2509'는 초형이 직립이고 내도복성이기 때문에 밀식 기계화 재배에 유리한 장점이 있다. 향후 이 품종은 순도 높고 종실수량이 많은 식용 및 조사료용 호밀 품종육성을 위한 중간모본으로 활용과 더불어 고품질 원료의 요구도가 높은 식가공 분야에 균일·안정성이 확보된 국내산 호밀 종자로 제공이 기대된다.

This study was conducted in 1991 and 1992 to determine the effects of winter annual forage corps such as winter rye (Secale cereale L.), rape (Brassica napus subsp. oleifera L.), oats (Auena satiua L.), crimson clover (Trifolium incarnatum L.), vetch (Vicia satiua L.) and Italian ryegrass (Lolim multiflorum Lam.) on subsequent growth, yield and quality of silage corn (Zea mays L.). The winter annual forage crops were seeded at the end of August and harvested in the fall and spring before corn planting. Corn-leaf numbers, plant heights and LA1 were generally reduced during early development when corn followed Italian ryegrass(P<0.05) and winter rye, but the silking date of corn was not affected by the winter annual forage crops. Corn dry matter and TDN yields were significantly reduced when corn followed Italian ryegrass and late maturing Kodiak winter rye. The yield reductions for corn following Italian ryegrass and Kodiak winter rye, relative to corn which did not follow the winter annual forage crops, were 49 and 19% respectively. but the corn yield was slightly improved by 2 and 3%, respectively. when corn followed crimson clover and vetch. No quality differences in corn stover were observed among the treatments except for the lowest ADF and NDF contents and the highest IVDMD where corn followed ltaliabn ryegrass.

A field experiment was conducted to evaluate the effects of cattle compost application on the change of soil physical properties and their relationship to yield performance of selected main forage crops. Maize(CV. Suweon 19) and sorghum hybrids(CV. Pioneer 9'31) as a summer crops and winter rye were grown on newly reclaimed red yellow soils(Fine loamy, Typic Hapludults) under different application rate of cattle compost associated with chemical NPK fertilization, from Oct. 1986 to Sept. 1989. Experimental field was laid down as a split plots design with four replications. The results obtained are summarized as follows: 1. Cattle compost application reclaimed soil physical propeties, such as formation of granular structure and water holding capacity, and it result in a great increase of plant growth and the rate of dry matter accumulation. 2. While cattle compost treatment reduced the portion of soild phase of the three phase constituents of soils, it increased the portion of air phase and liquid phase comparatively. 3. Organic matter, N, P, K, and mineral content in soil were markedly increased in the plot treated with compost. 4. Cattle compost application increased fodder production both in maize-rye and sorghum hybrids-rye cultivation. Annual dry matter yield of maize-rye cropping was 2183(NI'K only), 2425(NPK+compvst 3000 kg) and 2800kg/lOa(NPK + compost 6000kg/10a).

Nutrient accumulation in surface soil has become a serious problem for cucumber production in greenhouse. However, still in many cases, soil management practices are only focused on maintaining crop yield, regardless of sustainability related with soil chemical properties. This study was conducted to propose a sustainable soil management practice by investigating the impact of cover crop species and nitrogen rate of fertigated solution on cucumber yield and soil chemical properties in greenhouse condition. Rye and hairy vetch were tested as a fallow cover crop, and each amount of urea (1/2, 3/4, 1 times of N fertilizer recommendations), determined by soil testing result, was supplied in fertigation plots as an additional nitrogen source. The result showed that the yield of cucumber was higher in rye treatment than control and hairy vetch treatment. In addition, rye effectively reduced EC and accumulated nutrients from the soil. Meanwhile, N concentration of fertigated solution showed no significant effect on the growth and yield of cucumber. Consequently, these results suggest that it is desirable to choose rye as a fallow catch crop for sustainable cucumber production in greenhouse.

This experiment was conducted to investigate the effects of wheat bran addition on the fermentative quality and dry matter digestibility(Dh4D) of rye silage. This hexbage was ensiled by the conventional methods in small glass silo of 0.82 liter with addition of wheat bran of 0%, 5%. 01%, and 15%. mpectivery.The samples of rye silage were determined the pH, lactic acid, acetic acid and butyric acid. The DMD was evaluated by pepsin-cellulase technique method. The energy values (total digestible nutrients. TDN : digestible energy, DE : metabolizable energy, ME) were calculated by DMD. The results obtained were as follows : 1. The pH and butyric acid of rye silage were reduced with increasing of wheat bran addition, but the contents of lactic acid and total acid were increased. 2. TDN, DE and ME were increased with high rate of wheat bran addition. 3. Regression equation and correlation coefficients between Flieg's score(X) and DMD(Y) of silage were Y =48.7+0.157X(r=0.917, p<0.01). 4. Regression equation and correlation coefficients between level of wheat bran(X) and Flieg's score(Y) of silage were Y= 18.3+5.56X(r=0.929, p<0.01).

The quality of silages, made from whole crop barley, rye, spring oat, Italian ryeglass, orchardgrass, alfalfa and grass-legume pasture mixtures, were evaluated under two different conservation techniques in baled silage making (BS) and conventional silages(CS). Crops materials were harvested at the stage of the greatest dry matter accumulation(hard dough for barley, soft dough for rye and oat, late bloom for Italian ryegrass and others pasture species), and baled in a self constructed square baling chamber weighted by 25~30kg in dry matter basis. Each bales were wrapped with 0.05mm thick polyethylen plastic film and stored six months long in stack silos. Barley, rye, oat and Italian ryegrass including of pasture crops produced higher quality silages in the baled silage making, due to better organic acid fermentation and lower nutrient losses during the period of storage than those in the conventional silages. TDN contents of barley silages were 65.3% in BS and 63.7% in CS, NEL value of barley silages was improved hum 6.48MJ(CS) to 6.61MJ/kg(BS) in dry matter basis. Silage quality of rye, oat and pasture crops were also improved markedly in the baled silage utilization.

Roof structure of the traditional buildings in the Northeast Asia region including Korea contains the most complicated and crucial components of the building and therefore the issues such as cost down, productivity and the attempt to combine the traditional building methodology with contemporary building technology turn out to be vital to the survival of the old yet disconnected traditional building industry. One of the distinctive modern building technologies is handling life-cycle building information by constructing virtual buildings using BIM, building information modeling tools. In this paper we follow a procedure to implement some of the design modules to be applied in BIM tools which are platforms for constructing virtual building models. We focus on Gong-po components namely the bracket-sets which are the essential part that connects the middle parts to the top parts (the roof structure) which are considered to be the most elaborate parts of the traditional buildings. The target building to work with in this paper is the Sung-Rye-Moon which has special cultural and social meanings nowadays and we tested our understanding and the design modules such as the bracket-sets by constructing a virtual building model of Sung-Rye-Moon.

This study is aimed to analyze the effect of lactic acid bacteria inoculants (LAB) on quality of rye silage fermentation, harvested at early heading stage. The nutritive values were similar between the control and LAB inoculated silages. The pH of rye silage in LAB inoculation significantly decreased as compared to control (p<0.05). In addition, the content of lactic acid in LAB inoculation significantly increased (p<0.05), but the content of acetic acid in LAB treatments decreased. In addition, lactic acid bacterial counts in LAB inoculation significantly increased as compared to control (p<0.05). Therefore, we suggest that rye silage could be improved by novel lactic acid inoculation.
