  • 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.

  • Vicia angustifolia L. is native plant of winter annual leguminous weed in Korea. Objective of this research was to investigate the effects of V. angustifolia as green manure for rice production in sustainable agriculture. Seed size of V. angustifolia was smaller than that hairy vetch as control plant, while seed number in same amount was approximately 1.4-fold higher. V. angustifolia started stem elongation in early April. In addition, flowering and dead-ripe stages of the plant reached at May $5^{th}$ and June $1^{st}$, respectively. Growth of V. angustifolia-barley mixed cropping system in upland was promoted up to 101 cm of plant length compared to 46.6 to 60.9 cm that grown in paddy. Biomass yield of V. angustifolia was 14.5 kg $ha^{-1}$ in single cropping system of paddy soil, and the amount of nitrogen was 65 kg $ha^{-1}$. Moreover, self-reseedling of fallen seed from V. angustifolia grown in previous year in paddy soil was significantly higher than that hairy vetch plant. These results suggested that V. angustifolia can be uses as green manure in addition to reducing the mineral fertilizer application in rice production for sustainable agriculture.

  • 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.

  • To determine the effect of winter green manure crops for tillage and no-tillage organic pepper cultivation in plastic film house, five different green manure crops were cultivated during winter season. In nutrition composition of green manure crops, total nitrogen contents were higher in Vicia hirsuta and Vicia angustifolia than any other crops. The average dry weights of green manure crops were 8.3 ton per ha in tillage and 7.0 ton per ha in no-tillage, among green manure crops that of Secale cereale was the highest. Fertilizer supply was depended on the biomass of the cultivated green manure crops and nutrition contents, total nitrogen supply of V. angustifolia was 226 kg and that of S. cereale was 251 kg per ha in tillage field. In no-tillage field, N-supply of V. angustifolia was 197 kg and that of S. cereale was 222 kg per ha. In yield components of red pepper, fruit numbers per plant were 55.5 in green manure crop tillage and 37.0 in no-tillage cultivation. Among green manure crops, the yield of dried red pepper was the highest for V. angustifolia in both green manure crop tillage and no-tillage cultivation.

  • 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.

  • Several wild plant species are known to contain biologically active substances that are allelopathic to weed species as well as antioxidant to foods. Plant extracts or residues from leaves of 4 species, Achyranthes japonica (speedwell), Cucumis sativus (Cucumber), Trifolium repens (white clover), and Vicia angustifolia (narrowleaf vetch) were bioassayed against Medicago sativa (alfalfa) or Echinochloa crus-galli (barnyard grass) to determine their allelopathic effects, and used for measurement of antioxidant activities. The aqueous extracts applied on filter paper significantly inhibited root growth of alfalfa. Aqueous extracts or residues from V. angustifolia showed the most inhibitory effect on alfalfa or barnyard grass seedling growth and followed by A. japonica and T. repens. Oxidative stability by Rancimat method, antioxidant activity by TBA (2-thiobarbituric acid) method and DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity for the ground samples or methanol extracts were the greatest in V. angustifolia, although were less than those of commonly used antioxidants, BHT (butylated hydroxytoluene) and ascorbic acid. These results suggest that the wild plant species had potent allelopathic and antioxidant activities, and that their activities differed depending on plant species.

  • Somatic chromosome numbers for 10 taxa and karyotypes analysis for 6 taxa of Korean Vicia were investigated. Somatic chromosome numbers of treated taxa were 2n = 12, 14 or 24 and therefore they proved to be diploid or tetraploid with basic chromosome numbers of x = 6 or 7. The chromosome number of V. hirticalycina (2n = 2x = 12) was reported for the first time in this study. The chromosome numbers of nine taxa were the same as in previous studies; V. angustifolia (2n = 2x = 12), V. cracca (2n = 4x = 24), V. hirsuta (2n = 2x = 14), V. tetrasperma (2n = 2x = 14 + 2B), V. amurensis (2n = 2x = 12), V. chosenensis (2n = 2x = 12, 12 + 2B), V. unijuga (2n = 4x = 24), V. unijuga f. minor (2n = 4x = 24), V. venosa var. cuspidata (2n = 4x = 24). The karyotypes of V. cracca, V. amurensis, V. hirticalycina, V. unijuga, V. unijuga f. minor, V. venosa var. cuspidata were observed as 2 m + 8 sm + 2 st, 2 m + 2 sm + 2 st, 3 m + 1 sm + 2 st, 4 m + 6 sm + 2 st, 4 m + 6 sm + 2 st, 4 m + 8 sm, respectively.

  • Seed germination and dormancy of three green manure seeds such as hairy vetch, crimson clover and narrow-leaved vetch (Vicia angustifolia L.) produced in Milyang, southern part of Korea were investigated to provide a basic information on the stability of seedling establishment in green manure seeds. In addition, the effect of seed storage duration on the germinability of imported hairy vetch and crimson seeds was also investigated. To determine the seed maturity time of three green manure seeds, the seeds were harvested manually at May 25, May 30, and June 4, and the 100-seed weight, germinability and percentage of hard seed were evaluated. Freshly harvested seeds of three green manure crops were strongly dormant because of hard seed coat. Germination percentage of the three green manure crops varied depending on the seed harvest time ranging from 30 - 52% in hairy vetch, 16 - 35% in crimson clover and 2 - 61% in V. angustifolia, respectively. Of the three crops, crimson clover and V. angustifolia matured early on May 30 to June 4 (around 35 to 40 days after flower) but hairy vetch seed did not mature until June 4 based on the seed germinability. The matured seed of crimson clover and V. angustifolia germinated less than 20% while scarification on seed coat significantly overcome the innate dormancy. On the other hand, the seed germination of hairy vetch and crimson clover was lower under dark than in the presence of light. The germination percentage of the imported hairy vetch and crimson clover seeds showed high with 77 - 79%, 94 - 95%, respectively, but the seed germination significantly declined by 21 - 32%, 30 - 40% after one-year of storage under natural conditions. The seeds germinated only 8 - 13% for hairy vetch but crimson clover did not germinate at all after two years storage. These results indicate V. angustifolia and crimson clover mature at May 30 to June 4 but hairy vetch did not. The imported hairy vetch and crimson clover seeds should be used within one-year after import for stable seedling establishment in green manure-rice cultivation cropping system.
