To improve the soil condition for no-tillage organic pepper cultivation, four different green manure crops were cultivated. Fertilizer supply was depended on the biomass of the cultivated green manure crops, nitrogen supplies were 314kg in Vicia villosa and 341kg $ha^{-1}$ in Vicia angustifolia. In the microbial community analyzed by phospholipid fatty acid (PLFA) method, soil microbe populations were different among the green manure crops and fungi group was increased at Vicia angustifloia and Vicia villosa. The biological ratio indexes of fatty acids in the soils, the ratio of Gram-negative to Gram-positive bacterial PLFA and Ratio of aerobes to anaerobes were high at Vicia hirsute and Vicia tetrasperma suggesting the enrich of the aerobic conditions. The ratio of saturated to unsaturated fatty acids increased at Vicia angustifloia and Vicia villosa suggesting anaerobic conditions. Abundant biomass and uncomposted organic matter, the ratio of fungi to bacteria was increased at Vicia angustifloia and Vicia villosa.

Vicia bifolia Nakai (Fabaceae) and Cyperus compressus L. (Cyperaceae) have been ambiguous in terms of their distribution and taxonomic entities in Korea. The existence of these two taxa was confirmed when V. bifolia and C. compressus was found on Jellabuk-do, Gyeongsangnam-do, and Jeju-do. Vicia bifolia is similar to V. unijuga by having a pair of leaflets but is distinguished by the length of the petiole, the size and degree of longevity of the bracts, and the shape of the stipules. Cyperus compressus was found on Jeju-do, is similar to C. tenuispica, C. haspan, and C. flaccidus, but is distinguished by the branching pattern of the inflorescences and the size of scales and achenes. A description, differences from related species, a key to the taxa and photographs of Korean Vicia bifolia and Cyperus compressus are provided in this study.

This study was conducted to select promising green manure crops, providing sufficient amount of nutrients for satisfying fruit tree growth, with the overwintering cover crops grown in organic orchards in 2009. The cover covers were investigated in 13 organic orchards in Chonnam province in April and June. The dry matter in cover crops observed in April and June was the highest for Lolium multiflorum Lam. and Bromus japonicus Thunb., respectively. Total N and K production in April was the highest for Lolium multiflorum Lam, Vicia hirsuta (L.) S. F. Gray and Vicia angustifolia var. segetilis (Thuill.) K. Koch., respectively, with Bromus japonicus Thunb. in June. This study showed that the leguminous crops, Vicia hirsuta (L.) and Vicia angustifolia, would be the prospective cover covers as the both crops provided sufficient amount of N and $K_2O$ into the soil. Amount of $P_2O_5$ producing from all cover crops provided less than nutrient levels than those of recommended nutrient requirement for satisfying 10- to 15-year-old fruit tree growth.

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.

In order to evaluate the taxonomical relevance of seeds morphological characteristics, a macroand micro-morphological study was conducted on seeds of Korean Vicia (Fabacea). We collected 19 taxa of genus Vicia distributed in Korea and introduced one taxa from USDA. The morphological characteristic and testa texture of seeds were investigated using a Stereo-microscope (SM) and Scanning Electron Microscope (SEM). Most of Vicia seeds were found spherical or oblong and some seeds were oval and subglose. The largest seed was V. chosenensis ($4.3{\times}3.6{\times}2.6mm$), and the smallest was V. teterasperma ($1.7{\times}1.7{\times}1.5mm$). V. chosenensis and V. hirsuta were separated from other Vicia species by having a shiny in seed finish. In hilum shape, 14 species have linear and V. sepium was distinguished by having a circumlinear. In testa texture, they developed papilae, only V. hirsuta has lophate in level type. Deposition of the sheet-like debris between the papilae was observed in V. chosenensis, V. cracca, and V. unijuga. Polymorphism information content (PIC) values of the 13 qualitative morphological characters (QMC) were in the range of 0.0950 to 8863 with an average of 0.4611. PIC value of seed shape, seed colour, hilum colour were 0.7403, 0.8177, 0.883 respectively. Cluster analysis based on QMC detected three main clades. V. cracca, V. amurensis, V. amoena were involved in Group 1 and V. unijuga f. minor, V. unijuga, V. unijuga f. angustifolia, V. sepium, V. hirticalycina, V. hirsuta, V. linearfolia, V. chosenensis, V. pseudorobus, V. venosa var. cuspidata were involved in Group 2. V. nipponica, V. japonica, V. villosa, V. dasicarpa, V. bungei, V. angustifolia, V. tetrasperma were clustered in Group 3. Our research suggests that morphological characteristic and testa texture of seeds could be used as definers for the identification of genus Vicia.

The rice lamina inclination test indicated the presence of brassinosteroid-like active substances in immature Vicia faba seeds. Two of these were identified as castasterone and brassinolide by GC/MS and GC/SIM, respectively. Another active principle was identified as methyl 4-chloroindole-3-acetate by GC/MS and HPLC.

We have discovered Vicia grandiflora Scop., a newly invasive alien species in Baekun-ri, Okcheon-gun, Chungcheongbuk-do, Korea. This species is native to regions from Central and Southeast Europe to Central Asia and Iran and is reported as an invasive species in North America and Japan. This species is similar to the Vicia sativa complex (V. sativa subsp. sativa, V. sativa subsp. nigra) but can be readily distinguished by the undivided ovate to semi-hastate stipules of the upper leaves, yellowish petals, large size of its flower, and elongated hilum. In the field, V. grandiflora grows in disturbed sites near cultivated land, suggesting that their seeds are typically transported by vehicles along with fertilizer or livestock feed. Here, we present the morphological description, photographs, and sites of V. grandiflora growth, which will be useful in guiding the management of this invasive alien plant.
