This study was conducted at Korea's typical soil, loamy soil, to figure out the effect of how barley green manure (B), hairy vetch (HV) and the mixed-planting hairy vetch with barley green manure (HV/B) affecting on the yield of rice, usage of nutrient and soil characteristics. Supplying amount of nitrogen from HV, HV/B and B were 172.8 kg $ha^{-1}$, 64.3 kg $ha^{-1}$ and 38.6 kg $ha^{-1}$, respectively. Hairy vetch had the highest plant height and SPAD of rice and next was hairy vetch/barley, chemical fertilizer (CF), none fertilizer (NF), and green manure barley. The amount of rice yield was 5.51 ton $ha^{-1}$ with HV, and 4.24 ton $ha^{-1}$ with HV/B. The chemical characteristics of soil showed lower pH and exchangeable cations (Ca and Mg) at B, HV and HV/B plot rather than that of chemical fertilizer (CF) plot. However, the physical characteristics of soil and the porosity rate showed better tendency at the green manure crops than CF. Nitrogen nutrient balance was showed the most balanced at CF, otherwise field of application of green manure crops were required the appropriate nutrition management if future crops would be cultivated because nitrogen nutrient could be devastated or accumulated.

This experiment was performed to study growth and yield of rice (cv. Dongjinbyeo) and soil properties affected by the application of rice straw, compost, and hairy vetch. An application of rice straw and compost led to the decrease in plant heights and tillers compared with chemical fertilizer whereas hairy vetch application resulted in slight increase. Panicle no per plant was the highest in chemical fertilizer and there was no difference among organic matters. Grain per panicle was no difference among chemical fertilizer, rice straw, and compost whereas was the lowest in hairy vetch application. The 1,000 grain weights did not show any statistic difference and the ripened rate was enhanced in all treatments of organic sources compared with chemical fertilizer. Therefore, an index of rice yield of compost, rice straw, and hairy vetch to chemical fertilizer (100%) was 77, 72, and 103%, respectively. In addition, an application of organic sources led to the increase of soil pore space and this contributed to the improvement of soil physical property.

Some symbiotic characteristics of native Korean Rhizobium leguminosarum biovar viciae were analysed to get some informations desirable for cultivation of hairy vetch (Vicia villosa Roth) using its symbiont in Korea. The size of indigenous populations of R. leguminosarum biovar viciae was higher in seven upland soils showing $1.7{\times}10^2{\sim}5.8{\times}10^4cells\;g{\cdot}soil^{-1}$, which appeared to be 10% and 37% higher for cultivated and uncultivated soils of hairy vetch, respectively, than seven paddy soils with $1.7{\times}10^2{\sim}1.7{\times}10^4cells\;g{\cdot}soil^{-1}$. In symbiotic potentials, however, the yields of hairy vetch treated with 10-fold-diluted ($10^{-1}$) inoculum and 1000-fold-diluted ($10^{-3}$) one was 11.2% and 8.8% more, respectively, in paddy than upland. Hairy vetch inoculated with either strain KHR 106 from Sacheon or strain KHR 120 from Yesan among native Korean R. leguminosarum biovar viciae isolates was of similar yield increment of 16% (p < 0.05) in upland soils with native R. leguminosarum biovar viciae of $5.8{\times}10cells\;g{\cdot}soil^{-1}$. In case of coinoculation of the two strains, however, the yields was not significantly increased. In especial, isolate KHR 106, KHR 120, and KHR 122 from Suwon, which has also good symbiotic effectiveness, showed different protein profile patterns each other. As a result, hairy vetch is possibly able to use atmospheric nitrogen through symbiotic relationship with diverse native R. leguminosarum biovar viciae in Korean arable lands. For safe and good production of hairy, however, the use of superior strains with high symbiotic effectiveness and competitiveness will be desirable.

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 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.

This study was conducted to evaluate the growth inhibition of weeds and selectivity of crop species by hairy vetch residues. The growth of all the weed species was suppressed greater than 90% at the ratio 60 : 40 of hairy vetch residues and no weeds were emerged at 90 : 10 mixture in the greenhouse. It was noticed that broadleaf weed species were more suppressed compared to grass weed species. Growth of weeds was significantly reduced and the inhibition percent was increased with increasing application depths of hairy vetch mixture both in vinylhouse and in field conditions. Among the different application depths of hairy vetch mixture, 0.75 cm depth of application tended to inhibit more, but statistically no significant difference was observed between 0.5 cm and 0.75 cm application depth. The growth of weed species such as Galium spurium, Chenopodium album, Plantago asiatica, and Rumex japonicus was greatly suppressed in the vinylhouse and the growth of G. spurium, R. japonicus and Amaranthus retroflexus was suppressed significantly in the field condition. The growth inhibition of all the above mentioned sensitive weed species was approximately 80% at the application depth of 0.5 cm. Crop growth was not hampered by using the residues of hairy vetch. This study demonstrated that rotation crop residues of hairy vetch contained high allelopathic potential to different weed species without hampering the growth of crop species.

The plant height of hairy vetch was high to comparing with crimson clover, and that of crimson clover was the lowest while that of hairy vetch was the highest with one application of rare earth. The dry matter content of crimson clover and hairy vetch were 20.3% and 18.1%, respectively and the dry matter content between two species had little difference. In this study, the fresh yield of hairy vetch was higher than that of crimson clover, while the dry matter yield of crimson clover was higher than that of hairy vetch. But there were not significant difference between two species. Although the fresh and dry matter yield of both species were the high with one application of rare earth, there were not significant difference between three treatments of rare earth. The nutritive values of hairy vetch were higher than that of crimson clover Neural detergent fiber (NDF) and acid detergent fiber (ADF) content decreased with one application of rare earth. But crude protein (CP) and digestibility were not significant between rare earth applications.

Green manure crops can be efficient replacements of high nutrient materials such as livestock compost, organic fertilizers, etc. in organic farming. Grass-legume mixtures or mixed cropping of legumes with non-legumes can aid in abating the shortcomings of each plant type under monoculture (i.e. legumes have low biomass yields while grasses are poor at fixing nitrogen). This study was conducted to investigate the effects of barley (B) and hairy vetch (H) mixtures on green manure yield in nutrient accumulated organic upland soils of Korea. In one cropping season, single crops of barley and hairy vetch (Barley: 160 kg/ha, Hairy vetch: 90 kg/ha) as well as mixtures of both crops at different seeding rates (B66:H33, B33: H66) were grown and the obtained results are as shown below. The biomass yield and nutrient productivities were higher in barley-hairy vetch mixture. The biomass yield and total phosphorus content were higher for the mixed crops by 78~132% and 200% respectively than those of the hairy vetch monoculture. Total nitrogen content of the mixed crops was also higher than those of the barley monoculture by 43~44%. The biomass yield (5.60 Mg/ha) and nutrient contents (87.7 kg N/ha, 23 kg $P_2O_5/ha$) were highest in the case of B66:H33 seeding rate. Accordingly, this study concludes that the barley-hairy vetch mixtures cropped at B66:H33 seeding rate is efficient in increasing green manure productivity due to complementary effects observed and the highest biomass yield and nutrient contents.

It is possible to use hairy vetch as green manure for corn not only in corn single cropping but also in double cropping system of corn and fall oats. Fall oats and hairy vetch were mixed-sown after corn harvest and harvested as forage in the early of November, and then hairy vetch stubble was over-wintered and incorporated into soil at corn planting as green manure without N fertilizer (FO+HV-GM). Other treatments were fall oats without N fertilizer on corn (FO-0N) and with N fertilizer 200kg/ha on corn (FO-200N), hairy vetch green manure without N fertilizer on corn (HV-GM), and fell winter follow without N fertilizer on corn (WF-0N). Soil nitrate content, corn growth and nitrogen uptakes, and yield of corn were measured and compared during 2-year experimental seasons. Dry matter and N amount of hairy vetch at the plot of FO+HV-GM were 60% less than those at the plot of HV-GM. The N effect of hairy vetch green manure on corn at the plot of HV-GM was similar to that at FO-200N plot for two years. Soil nitrate at the plot of FO+HV-GM was below the half of those at plots of HV-GM and FO-200N at 6-leaf stage of corn. N uptake of corn at the plot of FO+HV-GM at silking stage was 30% less than those at plot of HV-GM and FO-200N. However, soil nitrate at 6-leaf stage of corn and the amount of nitrogen uptake of corn at silking stage increased two times and 30-40 kg/ha, respectively, compared with those at the plot of FO-0N. Corn yield at FO+HV-GM decreased about 2 ton/ha due to the decrease of corn grain weight in the first year compared with plot of HV-GM and FO-200N, but its difference was not shown in succeeding second year. Corn N uptake at FO+HV-GM decreased 60 kg/ha and 20 kg/ha in 1999 and 2000, compared with plot of HV-GM and FO-200N, respectively, but increased 30kg/ha and 45kg/ha compared with the plot of FO-0N in 1999, 2000, respectively. Therefore, it is estimated that hairy vetch green manure in fall oats-corn double cropping system can reduce nitrogen chemical fertilizer on corn as much as 50-100 kg/ha although its N effect is much lower than the N effect of hairy vetch green manure in corn single cropping of which N effect is over 200 kg/ha.

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.
