To select the most proper soil for root initiation from stem cuts of Birdsfoot trefoil (Lotus corniculatus L.), eight-week-old stem cuts were cultured on three types of soil [commercial bed soil, decomposed granite (DCG), and river sand] for one month. The results showed that the root initiation ratios on DCG (77.8%) and river sand (70.0%) were relatively high, but the ratio on commercial bed soil (41.1%) was very low. To examine the effect of rare earth (RE) and Indole-3-Butyric Acid (IBA) on root initiation from stem cuts of Birdsfoot Trefoil, stem cuts were cultured on two types of soil (DCG and river sand) with treatment of RE and IBA for one month. The root initiation ratios turned out to be 90.0% (DCG with 60 ppm of RE), 80.0% (river sand with 20 ppm of RE), 96.7% (DCG with 40 ppm of IBA), and 96.7% (river sand with 40 ppm of IBA). These results suggested that the most efficient way for root initiation of Birdsfoot trefoil was to culture the stem cuts on river sand or DCG over 30 days with IBA treatment (40 ppm).

Optimum tissue culture conditions for an efficient induction of embryogenic callus from mature seeds of perennial ryegrass (Lolium perenne L.) and regeneration of plants from callus tissues were investigated. MS medium containing 3 mg/L 2,4-D and 0.1 mg/L BA was optimal for embryogenic callus induction from mature seeds. The highest plant regeneration frequency (58.3%) was observed when the embryogenic callus tissues were cultured on N6 medium supplemented with 1 mg/L 2,4-D and 3 mg/L BA. Regenerated plants were grown normally when shoots transplanted to the soil. A short tissue culture period and high-frequency regeneration system would be helpful for molecular breeding of perennial ryegrass through Agrobacterium-mediated genetic transformation.

Cytokinins are essential plant hormones that play crucial roles in various aspects of plant growth and development. By using mRNA differential display, we isolated a cytokinine-inducible cDNA encoding pathogenesis-related (PR) 4 from Arabidopsis amp1 mutant. The full-length PR4 cDNA, designated AtPR4, contains an open reading frame of 212 amino acids with calculated molecular mass of 22,900 Da and isoelectric point (pI) of 7.89. Genomic DNA blotting showed that the Arabidopsis genome has one copy of AtPR4. AtPR4 mRNA was induced by cytokinin and NaCl, but decreased by SA or JA treatment. PR proteins are induced in response to pathogen attack. Thus the AtPR4 gene isolated in this study may be a useful candidate for genetic engineering of forage crops for increased tolerance against pathogen.

This experiment was conducted to compare the agronomic characteristics and productivity in introduced hairy vetch cultivars and developed new Korean Hairy vetch cultivars in two areas of the experimental field of Grassland and Forage Crops Division, National Institute of Animal Science from 2005 to 2006. The experiment was arranged in randomized complete block design with three replications. A total of 11 hairy vetch cultivars used in this study including 9 introduced cultivars (Penn-02, Sander, Latigo, Welta, Ostsaat, VV4712, Minnie, Barlosa and Capello) and 2 Korean cultivars (Cold green and Cheong pa). The early flowering varieties of Minnie, Barlosa, Capello and Cold green were grown as early maturity cultivars, while the late flowering varieties of Penn-02, Sander, Latigo, Welta, Ostsaat, VV4712 and Cheong pa were grown as medium and late maturity. The winter hardiness of hairy vetch was good except for Minnie, Barlosa and Capello of early maturity cultivars. In this study, dry matter yield of VV4712 was the highest of 11 hairy vetch cultivars. And dry matter yield of medium and late maturity vetch increased in the middle region while that of early maturity increased in the south. The new Korean cultivar, Cheong pa, as a medium and late maturity hairy vetch was not bad compared to introduced cultivars and Cold green as an early maturity hairy vetch was an excellent cultivar compared to introduced cultivars in both regions. Latigo in NDF (neutral detergent fiber) and Welta in ADF (acid detergent fiber) were lower than other cultivars, while Sander in IVDMD (in vitro dry matter digestibility) and CP (crude protein) content were higher than other cultivars. The results of this experiment indicated that the productivity of hairy vetch cultivars was highest in VV4712, and Cheong pa and Cold green of new Korean cultivar were the promising cultivars of hairy vetch in Korea.

The objective of this research was to develop a high yielding, early and medium-late flowering new hairy vetch(Vicia villosa Roth) varieties derived from an accession in Korea. Most vigorous early and medium-late flowering hairy vetch lines were selected and crossed by open pollination and their seeds were bulked and plants were reselected at Seongju in the Keongbuk and at Sacheon in the Keongnam. A performance trial was conducted to evaluate agronomic characteristics, forage quality and dry matter(DM) yield of new hairy vetch early-maturing 'Cold green' and medium-late maturing variety 'Cheong pa' at Seongju and Sacheon. 'Cold green' and 'Cheong pa' are hair but 'Haymaker plus' and 'Latigo' are nearly hairless. 'Cold green' has purple flowers while 'Cheong pa' has violet. The cold tolerance of 'Cold green,' 'Cheong pa' and 'Latigo' was higher than 'Haymaker plus' at Seong-ju, Keongbuk province, in inland region but there were a little differences at Sacheon, Keongnam province in southern coast region. Fifty percent-flowering dates of 'Cold green' and 'Haymaker plus' had earlier than others and 'Cheong pa' was earlier than 'Latigo'. The DM yield of 'Cold green' was higher than that of others, but 'Cheong pa' and 'Haymaker plus' had higher than 'Latigo' at Seong-ju(P<0.05). In Sacheon, The DM yield of 'Cold green' and 'Haymaker plus' was higher than others and 'Cheong pa' had higher than 'Latigo'.

This experiment was carried out to evaluate the effects of organic content and to select lodging resistance for six varieties in paddy field of Chungnam province from 2006 to 2007. In this experiment, plant height was increased at the high fertile field and dry matter rate (%) per fresh matter was decreased at the high fertile soil condition but dry matter rate (%) of spike was increased. The dry matter (DM) yield showed higher in Sunwoo barley (13,520kg/ha) and Youngyang barley (12,780kg/ha) at the high fertile field. Fresh yield was also high in Wooho barely (34,720kg/ha) and Youngyang barely (33,670kg/ha) at the high fertile field but yield in high and normal fertile soil condition was not difference. Total digestible nutrients (TDN) content of Youngyang barley and Yuyeon barley was high as 69.5%, 70.3%, respectively, at the high fertile soil condition. According to this result Soman barley and Youngyang barley might be recommendable for whole crop barely in lower organic content condition of paddy rice field and Wooho barley and Soman barley with the lodging resistance and high yield is suitable for paddy field with high organic content.

This experiment was conducted to determine the effect of seeding method on winter survival and dry matter yield of Italian ryegrass(Lolium multiflorum Lam. "Kospeed") in paddy field for two years. The experiment was arranged in randomized complete block design with three replications. The treatment consisted of four different seeding methods, R-LS-P(rotary-line sowing-packing), R-BS-P(rotary-broadcast seeding-packing), R-BS(rotary-broadcast seeding), R-BS-TR(rotary-broadcast seeding-trifling rotary), BS-TR(broadcast seeding-trifling rotary). The emergence ratio of broadcast was decreased by 12% and winter survival was decreased by 17% compared with line sowing. The R-BS-TR treatment which was practical seeding method of rye was decreased seeding stand ratio by 65.2% and winter survival by 6.7% compared with others seeding methods. Dry matter yield of line sowing(8,151 kg/ha) was higher than that of broadcast(6,281 kg/ha) and R-BS-P treatment was the highest DM yield as 7,166 kg/ha. There was not found significant difference among seeding method in forage quality. The results of this experiment indicated that R-BS-P(rotary-broadcast seeding-packing) was recommendable the best seeding method after harvested whole crop rice in paddy field.

This experiment was conducted to investigate the selection of regional double cropping system for production of organic forage in middle part of Korea. The species of forage crop used in this experiment were corn,
hybrid and japanese millet for summer crops and rye and Italian ryegrass for winter crops.
hybrid showed higher DM (dry matter) and TDN (total digestible nutrient) yield than that of corn. Dry matter yield of corn decreased to 56% that of control because of weed. In winter crops, DM and TDN yield of rye is higher than that of Italian ryegrass. Rye was more adequate to produce organic forage in middle part of Korea. We could not find out the difference of nutrient value between each treatments. It means that the amount of nutrient is affected by DM productivity of each crop. The result of this study indicated that
hybrid (summer crop) and rye (winter crop) cropping system could be recommended as producing high yield of organic forage in middle part of Korea.

Surface sowing method is one of the important methods to establish seeds in mountainous area. Seed-coating technique in the surface sowing method is increasing interest in the world today. An experiment was conducted to develope a technique for pelleting seeds of grass in woodland. Results showed that the seed pelleting was a useful technique than coating seeds because the pelleting reduced coating time and increased amounts of coated seeds per hour. As lowering temperature and reducing time for drying, germinating energy and germination rate of pelleted seeds were improved. And emergence, establishment and early growth of pelleted were also improved in pasture under woodland. Based on this study, we could conclude that the seed pelleting is a useful technique for the establishment and early growth of grass under woodland.

The experimental work was conducted to determine the growth characteristics and yield of whole crop rice (cv. Suwon 468 and cv. Chuchungbeo) and soil properties using various type of livestock manure application on rice paddy land for 3 years (
). Compared Suwon 468 and Chuchungbeo, Suwon 468 has longer plant height and more DM yield than that of Chuchungbeo. Among livestock manure type, plant height was longer in order of liquid swine manure (LSM) > composted swine manure (CSM) > chemical fertilizer (CF) > composted cattle manure (CCM). Number of branch on Chuchungbeo had more than that of Suwon 468. Among livestock manure type, number of branch had more in order of LSM > CSM > CF > CCM. DM yield of whole crop rice (WCR) was affected by various types of livestock manure application and increased in order CSM > CCM = LSM. DM yield on the effects of application level of LSM was highest in LSM 75% + CF 25%. Plant diseases such as rice blast, damage by insect, smut, sheath blight occurred in LSM and CSM and there was not significantly different among application level of LSM. The nitrogen content of WCR by CSM was the highest of all treatments and the ripened ratio by CSM was in contrary order. Moreover the feed value of WCR was not significantly different among treatments. Soil pH, organic matter and total nitrogen was not different by LSM application whereas phosphorus content increased by LSM application. Cu and Zn content increased by LSM and CSM application and were not different by CCM as compared to control plots.

This study is conducted to evaluate economical value of Jeju grassland and validity of its preservation, and draw up several measures to support. To measure its economical value, this study examined its environmental value and social and cultural value. For environmental value, this study used replacement method while it applied CVM method, a widely used method, to assess social and cultural value and two-level two-best choice selection method, which ask questions by assuming virtual circumstances to avoid reflecting some biased opinions. Jeju grassland has multiple functions-environmental functions such as preventing soil corrosion and flood, handling animal excrement, and purifying air, and social and cultural functions such as promoting physical and mental health and providing recreation places. From the results of the feasibility study, Jeju grassland's annual multiple functions are assessed to have a total
million won worth. In addition, it is found that Jeju visitors recognize Jeju grassland for its functions to contribute to public interests. That is, they think it can provide attractive views and educational and recreational places and promote emotional development. Especially, many people presented their ideas that it be continuously preserved since it is worthwhile for us and our next generations. To preserve grassland's cultural resource, which create a huge economic value like this, the Government has to support a certain amount of financial aid for turning to a better grassland environment and its maintenance to realize environment-friendly livestock farming on Jeju Island and promote its tourism industry and consequently, add more value to Jeju.

The object of this experiment was to investigate the food habits of dairy goats fed with various roughage sources. The experimental trials were conducted at Chungnam National University in 2007. The experimental roughages include five sources and 25 species in all; grass sources: 5 species (Lolium perenne, Festuca arundinacea, Poa pratensis, Agrostis alba and mixed grass, legume sources: 5 species (Trifolium pratense, Medicago sativa, Trifolium repens, Melilotus officinalis and Vicia villosa), browse sources : 5 species (Quercus serrata Thunb., Prunus jamasakura Sieb., Quercus aliena Blume, Robinia pseudoaccacia and Pinus densiflora), weed sources: 5 species (Artemisia princeps Pampanini, Erigeron canadensis, Alopecurus aegualis Sobolewski, Echinochloa crusgalli var. frumentacea (Roxb.) Wight and Rumex crispus), and native grass sources: 5 species (Zoysia japonica Steudel, Agropyron tsukushiense var. transiens (Hack) Ohwi., Arundinella hirta (Thunb.) Tanaka, Miscanthus sinensis Anderss and Phragmites comunis Trin). Ten dairy goats(Saanen) were selected which had nearly the same body weight(average 31kg). Experimental roughages were prepared by 0.5kg per 1 species fed to dairy goats, and the experiment was carried out from 09:00 to 18:00. The chemical composition and dry matter digestibility of each roughage source and species were significantly different at the sampling area, plant species, growth stages and cutting period. The dairy goats ate more roughages which had low fibrous contents, but high dry matter digestibility. Among all the 25 species of roughages, the favorite intake species order by dairy goat was observed like this: perennial ryegrass, tall fescue and red clover, respectively, and the lower intake species order was Rumex crispus. On the other hand, compared to each roughage source, total intake amount by dairy goats was showed as forage grasses (59.0%) which contained grasses(33.3%) and legumes (25.7%), browse (19.6%), weeds (15.9%) and native grasses (5.5%). Based on the result, the food intake type of dairy goats seems to be closer to grazer type.

An in vitro study was conducted to examine the influence of alcohol-fermented feedstuff formulated with byproducts on the fermentation characteristics and NDF disappearance in the rumen. Dietary treatments were either a soybean curd-based alcohol-fermented feedstuff (AFS) or brewery grain-based alcohol-fermented feedstuff (AFB). The AFS and AFB are composed of 50% commercial beef cattle feed, 50% soybean curd dreg, 5% molasses and 0.5% yeast and 25% commercial beef cattle feed, 25% brewery grain, 25% soybean curd dreg, 25% corn grit, 5% molasses and 0.5% yeast, respectively. The change of ammonia, pH alcohol, volatile fatty acids, and NDF disappearance were measured at 0, 2, 4, 8 and 12 hr after in vitro incubation in the rumen. After 2 hr incubation, higher ammonia concentrations were resulted in AFS (12.47 mg/dl) and AFB (12.85 mg/dl) compared to control (11.84 mg/dl) (p<0.05). Ruminal pH of AFS and AFB were significantly higher than control during 1 to 6 hr fermentation, but the pH of AFS and AFB were decreased after 6 hr. At 12 hr fermentation, the alcohol concentration of AFS and AFB was significantly increased by 43.9% and 48.0%, respectively. The acetate concentration was rapidly decreased in control, while the concentration was slowly decreased in AFS and AFB with increasing the fermentation time. Lower concentrations propionate and butyrate were observed in AFS and AFB during every fermentation time (p<0.05). The NDF disappearance was significantly lower in AFS and AFB after 4 hr fermentation. These results suggest that alcohol fermented feedstuff can control the fermentation pattern in the rumen.
