A field experiment was conducted to evaluate agronomic characteristics, forage quality and dry matter yield of Korean native wild hairy vetch(Vicia villosa Roth) and introduced vetch(Vicia) cultivars from Australia. Seeds were sown on 29 August 1998 and 29 September 1999 at the Livestock Experiment Farm, Keimyung College, Kyeongsan, Kyeongbuk. Vetch plants were harvested on 14 November 1998 and 5 May 1999 and 29 April 2000. 'Haymaker plus' and 'Cappelo woolly pod' (Vicia villosa ssp. dasycarpa(Ten.) Eav.) were higher than 'Namoi' (Vicia villosa ssp. dasycarpa(Ten.) Eav.) in winter survival and 'Popany' (Vicia benghalensis L.) and 'Victa' (Vicia sativa L.) did not overwinter from 1998 to 1999. 'Haymaker plus', 'Cappelo woolly pod', 'Namoi', Korean native wild hairy vetch and Chinese milk vetch were overwintered from 1999 to 2000, except 'Aneto common' (Vicia sativa L.). Fifty percent flowering was observed 23 April for 'Namoi', 24 April for 'Cappelo woolly pod' and 26 April for 'Haymaker plus' from 1998 to 1999. In 1999~2000, fifty percent flowering was observed 12 April for 'Namoi' and 'Cappelo woolly pod', 14 April for 'Haymaker plus', 23 April for Chinese milk, 30 April for 'Aneto common' and Korean native wild hairy vetch. Dry matter yield per hectare was significantly higher(p<0.05) for 'Haymaker plus', 'Cappelo' and 'Namoi' than 'Popany' and 'Vicata' from 1998 to 1999. In 1999-2000, dry matter yield per hectare was higher(p<0.05) for 'Namoi', 'Haymaker plus', 'Cappelo woolly pod' and Korean native wild hairy vetch than Chinese milk vetch (Astragalus sinicus L.) and 'Aneto common'. CP content was relatively high, but Chinese milk vetch and 'Aneto common' were lower than other cultivars. ADF(acid deterguent fiber) was low in Chinese milk vetch, but between the other cultivars were similar. According to the results obtained from this study, it is suggested that 'Haymaker plus' would be recommendable for fall sown vetch for dry matter production.

Forage legumes are being used as an important source of protein for dairy farm as well as nitrogen fertilizer. This experiment was conducted to evaluate forage production and quality of five legumes at Cheonan Yonam College Experimental Livestock Farm for 1 year(2001-2002). Five legumes were crimson clover (Trifolium incarnatum L.) 'Tibbee', hairy vetch(Vicia villosa Roth) 'Common', red clover(Trifolium pratense L.) 'Kenland', persian clover(Trifolium resupinatum L.) 'Leeton', alfalfa(Medicago sativa L.) 'Vernal'. All legumes were shown cold hardiness of 8 rating or higher except crimson clover(7 rating). Flowering stage was observed 23th of April for crimson clover, 13th of May for hairy vetch, 3rd of May for red clover, and 12th of May for alfalfa. But persian clover didn't at harvest. Dry rnatter(DM) of crimson clover(17.6%) was the highest among legumes. In DM and total digestible nutrients(TDN) yields, crimson clover and hairy vetch were higher than those of other legumes. The crude protein of hairy vetch(20.5%) was the highest among legumes. In neutral detergent fiber(NDF) and acid detergent fiber(ADF), persian clover was the lowest(35.0% and 25.0%). Calculations of relative feed value(RFV) based on NDF and ADF of legumes were over 125(Prime degree) except hairy vetch. RFV and TDN of persian clover were the highest among legumes. According to the results of this study, crimson clover and hairy vetch are excellent in forage yield. Persian clover is superior in forage quality among legumes.

This experiment was conducted from 1991 to 1993 at the forage experimental field, College of Agriculture and Life Sciences, SNU, Suweon to investigate the effects of previous crop residues on growth and yield of succeeding corn(2ea mays L.) and also to determine the best double cropping system necessary to maximize the total dry matter yield of winter forage crops plus corn for silage. In this experiment, treatments consisted of no crop as a control, late maturing Kodiak rye(Seca1e cereale L.), Bamapoli forage rape(Brassica napus Subsp. oleifera L.), G-sprinter oats(Avem sativa L.), Chief crimson clover(Trifolium incarnatum L.), Jackson Italian ryegrass(lo1ium rnultiJlorum L.), Vantage vetch(Vicia sativa L.) and early maturing Koolgrazer rye(Seca1e cereale L.). Corn leaf number and silking date were not significantly affected by previous crop residues, but the leaf number of corn following Italian ryegrass was reduced by 1.9 relative to no previous crop. The plant height and LA1 were significantly reduced during early development when corn followed Italian ryegrass and late maturing Kodiak rye (p<0.05). The dry matter and estimated TDN yields of corn were significantly reduced when corn followed Italian ryegrass and late maturing Kodiak rye. The yield reductions for corn following Italian ryegrass, late maturing Kodiak rye and early maturing Koolgrazer rye, relative to com when no previous crops were planted, were 34, 17 and 8%, respectively. Therefore, the reduction in corn growth and yield in this experiment could be explained by an allelopathic effect resulting from the Italian ryegrass and rye residues. The highest total dry matter yield of 30,509kg/ha was obtained from an early maturing rye-corn double cropping sequence in combination among the eight cropping systems.

The esterase isozyme of several legume plants were separated and visualized by horizontal starch gel electrophoresis using enzyme-specific staining. Extracts used were prepared from fully expanded young leaf and stem of six legume species which were red clover(Trifolium Pretense L.), ladino clover(Trifolium repense L.), wild white clover(Trifolium repense L.), alfalfa(Medicage sativa L.), mimosoides(Cassia mimosoides var nomame Makino), and amoena(Vicia amoena Fisch). The number of band, Phenotype and staining intensity of esterase isozyme in leaf and stem varies depending on the plant species. However, there are little difference between leaf and stem esterase isozyme in same species except alfalfa. And in the leaf and stem of mimosoides and amoena showed not any esterase(Fig. 2). Among the examined plants, the highest staining intensity and the rapidest migrating esterase isozyme was Est 1.

Greenhouse and laboratory studies were conducted to investigate the allelopathic potential of alfalfa and vetch residues on soybean and corn using various extract concentrations (0, 5, 10, 15 and 20%, w/v) and residue rates (0, 0.25, 0.5, 0.75 and 1%, w/w). Aqueous extracts of alfalfa (Medicago sativa L.) and vetch (Vicia spp.) exhibited an allelopathic effect on soybean and corn seed germination, seedling length and weight. The degree of inhibition significantly increased as the aqueous extract concentration increased. Alfalfa and vetch 20% extracts reduced soybean seed germination, seedling length and weight by 35%, 57%, 32% and 15%, 42%, 25% respectively, when compared to control. Corn germination, seedling length and weight was inhibited by 20%, 23%, 38% by alfalfa and 19%, 18%, 35% by 20% vetch extracts. Alfalfa and vetch extracts inhibited secondary root formation and branching as the extract concentration increased. Alfalfa and vetch 20% extracts inhibited by 41% and 32% secondary root numbers, respectively as compared to control. It was found that the aqueous extract of alfalfa resulted in greater reduction in germination, seedling length and weight of soybean than that of vetch. Alfalfa and vetch 1% residue rate inhibited soybean plant height by 30% and 10%, leaf area by 31% and 23%, and dry weight by 18% and 1%, nodule number by 27% and 20% also. Alfalfa and vetch residue significantly enhanced plant height, leaf area and dry weight of corn. The maximum stimulation occurred with 0.25% and 1% of alfalfa and vetch residue rates, respectively. Plant height, leaf area, and dry weight increased by 23%, 59%, 58% and 17%, 52%, 94% with alfalfa and vetch residues of 0.25% and 1%, respectively. This study demonstrates that there is an allelopathic potential resulting from alfalfa and vetch residues on soybean growth and yield. It also suggests that these residues may affect crop growth and development due to the inhibitory or stimulatory effects of allelochemicals existing in the residue.

This experiment was conducted to compare the agronomic characteristics and productivity in induced vetch cultivars at paddy field of Cheonan (National Institute of Animal Science) and Naju (Jeollanam-Do Agricultural Research and Extension) from 2004 to 2006. The vetch cultivars used in this study were 6 varieties ('VV4712', 'Welta', 'Penn-02', 'Ostsaat', 'Oregon com.', 'Sander 2'). At the Naju region, the most fast flowering date variety was Chinese milk vetch, Sander 2 was very late as 20th May. The average dry matter (DM) content was 21.7%. Vetch cultivars were severely different. 'Oregon com.' showed the highest DM yield by 5,406 kg/ha but the DM yield of 'Ostsaat' was low by 4,852 kg/ha. At the Cheonan region, the most fast flowering date variety was Korean milk vetch, Sander 2 was very late as 25th May. The average dry matter (DM) content was 16.9%. Vetch cultivars were severely different. 'Welta' and 'Ostsaat' showed the highest DM yield by 2,173 kg/ha and 1,883 kg/ha respectively, but the DM yield of 'VV4712' was low by 1,079 kg/ha. Crude protein (CP) content of vetch was 11.5%. 'Sander 2' showed the highest CP content by 14.4% and Chinese milk vetch showed the highest content by 19.3%. Average acid detergent fiber (ADF), neutral detergent fiber (NDF) and total digestible nutrient (TDN) content were 26.8%, 42.2% and 67.5%, respectively. The results of this experiments indicated that the productivity of vetch cultivar varied from winter hardness, therefore we will consider the winter hardness as main factor when induce vetch cultivars. According to the results obtained from this study, it is suggested that 'Oregon com.' at the Naju region and 'Welta' and 'Ostsaat' at the Cheonan region would be recommendable for fall sown 'vetch' for dry matter production.

This experiment was conducted to compare the agronomic characteristics and productivity of induced annual legumes at paddy field of Cheonan and Naju from 2004 to 2006. Chinese milk vetch (wild type), crimson clover (C.V. Linkarus), forage pea (C.V. Austrian pea), hairy vetch (C.V. Oregon commen) were used in this study. At the Naju region, the earliest flowering on 2nd may was found in Chinese milk vetch, while the latest on 18th May in forage pea. Fresh, dry matter (DM) and crude protein (CP) yields of crimson clover were highest as 28,870, 6,986 and 943 kg/ha, respectively. but the yield of chinese milk vetch was low by 9,885, 1,749 and 338 kg/ha. At the Cheonan region, the most fast flowering date variety was Chinese milk vetch, hairy vetch was very late as 19th May. Fresh, DM and CP yields of hairy vetch were highest as 7,916, 1,141 and 113 kg/ha, respectively. but the yield of chinese milk vetch showed the lowest by 270, 42 and 8 kg/ha. The CP content of annual legumes was 14.3%. chinese milk vetch showed the highest CP content by 19.3% and hairy vetch showed the lowest content by 9.9%. The present data showed that the productivity was closely dependent on winter hardness, in conclusion, crimson clover at Naju and hairy vetch at Cheonan region was suggested to be the most proper species as winter crop after rice harvest on paddy field when considered the winter hardiness.
