Trifolium resupinatum L. (Fabaceae) is native in Southern Europe and Southwesten Asia. This species is known as a naturalized plant, which is widely distributed in the world. We first found it in the Eushincheon river bank of Jindo Isl., Jeollanam-do, South Korea. T. resupinatum can be easily distinguished from the other species of the same genus by its resupinate flower. The Korean name "Geo-kkul-kkot-to-kki-pul" indicates its distinctive characteristic of flower.

The nutritive value of 4 straws, obtained after thrashing of seeds from fodder crops, was assessed as complete feed for ruminants. Sixteen male Murrah buffaloes (liveweight 365.8${\pm}$19.5 kg), were divided into 4 equal groups and offered ad lib. straw of either Trifolium resupinatum, Trifolium alexandrium, Medicago sativa or Lolium perenne, supplemented with minerals and vitamin A, for 40 days in a completely randomized design. Simultaneously, each straw was offered to 3 rumen fistulated male buffaloes in order to assess the biochemical changes in the rumen. Compared to other straws M. sativa straw had higher (p<0.05) organic matter (OM), crude protein (CP), acid-detergent fiber (ADF) and cellulose content. L .perenne had the highest (p<0.05) hemicellulose and lowest (p<0.05) CP and acid-detergent lignin (ADL) content. T. resupinatum had the lowest concentration of cell wall constituents (CWC). The digestibility of nutrients of T. resupinatum and L. perenne straw was similar, but higher (p<0.05) than that of other straws. M.sativa straw showed highest (p<0.05) digestibility of CP. The highest OM digestibility of T. resupinatum and CP digestibility of M. sativa were responsible for highest (p<0.05) total volatile fatty acids and trichloroacetic acid precipitable nitrogen in the strained rumen liquor. The digestible crude protein (DCP) was highest (p<0.05) in M. sativa followed by that in T. alexandrium. The total purine derivatives excreted in urine varied from 0.22-0.32 mmol/kg $W^{.75}/d$. The efficiency of microbial protein synthesis indicated that OM of straws of M. sativa and that of T. alexandrium was used more (p<0.05) efficiently. The microbial protein synthesized was highest in T. resupinatum, but statistically similar to other groups. The values for N-retention and apparent biological value were highest for L. perenne, though comparable with that of M. sativa and T. alexandrium. The available metabolizable energy (ME) was highest (p<0.05) in T. resupinatum followed by that in L. perenne and lowest in M. sativa. It was concluded that all the straws, supplemented with minerals and vitamin A, could be fed exclusively to adult ruminants with no adverse affect, as animals were able to maintain body weight (372${\pm}$20.1 kg).

This experiment was conducted to compare the agronomic characteristics, flowering condition and productivity of introduced annual legumes at paddy field of Seonghwan(Cheonan, Chungnam, Korea) from September 2006 to May 2007. Annual legumes used in this study were hairy vetch(Vicia villsa, Rosa), crimson clover(Trifolium incarnatum, Contea), berseem clover(Trifolium alexandrinum, Alexandria), persian clover(Trifolium resupinatum, Prolific), balansa clover(Trifolium michelianum, Paradona), sweet clover(Melilotus officinalis, Yellow) and forage pea(Pisum sativum, Austrian). Emergency rate after seeding were 90% or more in crimson clover, hairy vetch, forage pea and berseem clover. Wintering of hairy vetch and crimson clover were excellent as 98% and 95%, respectively. Flowering rate of harvesting date(May 10) was 100% in crimson clover, 98% in balansa clover, 5% in persian clover and others were not flowering. Fresh and dry matter yield of crimson clover were highest as 72,556 kg/ha and 16,062 kg/ha, respectively. Crude protein yield of hairy vetch was highest as 2,929 kg/ha but not significant with crimson clover(2,169 kg/ha). TDN yield of crimson clover was highest as 9,007 kg/ha but not significant with hairy vetch(7,366 kg/ha). According to the results from this study, it is suggested that crimson clover would be recommendable for autumn-sowing annual legume at paddy field of Central Provinces.

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.

No comprebensive forage quality of annual legumes harvested and cured in spring has been conducted in Korea. Therefore, this experiment was carried out to gain information on the quality of crimson clover (Trifolium incarnatum L.), bolta baIansa clover(Trifolium ba/anansae L.), and persian c1over(Trifolium resupinatum L.) during field curing in spring. The dry matter content of crimson clover at harvest was 24.7%, while bolta balansa and persian clovers had 20.4 and 18.8%, respectively. The moisture content of persian clover was low at the final curing day. But All species took 4 days to reach moisture content under 20%Tedding frequency did not affect moisture content, but consisten trends were also observed during the field curing. Persian clover tended to show a higher leaf-stem ratio than crimson and bolta balansa clovers on dry matter basis. Crude protein of persian clover(19.5%) was higher than other legumes. The percentage of erode protein was decreased from 17.8 to 16.5% as tedding frequency often did. Neutral detergent fiber(NDF) and acid detergent fiber(ADF) contents of persian clover were lower than those of other legumes. From the comparison among tedding frequency, NDF and ADF contents of three times were higher than those of one and two times. Relative feed value(RFV) of persian clover hay was the highest(178) and classified as Grade Prime in forage quality standard. Crimson and bolta balansa clovers in the RFV were also high quality as Grade 1 in forage quality standard. The RFV of legume hay was decreased from 150 to 140 as tedding frequency often did Results of the experiment indicate that hay quality of persian clover was higher than other clovers. And this is due to high leaf and stem content, hollow stem and late maturity stage. Then tedding frequency in annual legume can be teded by two times for quality.
