To investigate a comparison of rice yield and quality by a utilization of green crops using barley and hairyvetch, this study was carried out in rice (Oryza sativa L.) organic cultivation field. Convention barley harvest (CBH), Green barley crop (GBC), Green barley+Green Hairyvetch crop (GB+HVC), and Non-Green crop (NGC) were treated in rice cultivation field. The results obtained as following: 1) Culm length and pancile length in Convention barley harvest (CBH) cultivation were longer than organic cultivation but were not significant difference in all treatments. Yields of milled rice in Green barley crop (GBC) and Green barley+Green Hairyvetch crop (GB+HVC) were by 90.3% and 95.9%, respectively. 2) Protein contents in Green barley crop (GBC) and Green barley+Green Hairyvetch crop (GB+HVC) were by 5.7% lower than 6.6% in Convention barley harvest (CBH) cultivation. Amylose contents in all treatment were similar as range 18.8% to 19.1%. Whiteness contents in Green barley crop (GBC) and Green barley+Green Hairyvetch crop (GB+HVC) were slightly higher by 38.9% and 39.1%, respectively, than 37.7% in Convention barley harvest (CBH) cultivation. 3) Palatability values in Barley harvest (BH) and Non-Green crop (NGC) were slightly higher by 82.0 and 83.8, respectively, than 77.6 in Convention barley harvest (CBH) cultivation. 4) Head rice in Non-Green crop (NGC) was 95.5%, while that of Convention barley harvest (CBH), Green barley crop (GBC), and Green barley+Green Hairy-vetch crop (GB+HVC) were slightly low as range 93.8% to 94.2%. White core and belly rice in Convention barley harvest (CBH) cultivation was the highest level by 1.7%. 5) Leaf blast, neck blast, sheath blight, rice stem maggot, rice leaf roller, rice leaf-tier, and green rice leafhopper were occurred lightly in rice field.

This research carried out to figure out the effect of the green manure crop cultivated at a preparation field and the shading net on the growth, development, and quality of ginseng. Followings are results obtained from the research. Leaf width of ginseng under the shading net of a two-layered blue and two-layered black polythylene net (TBTBPN) was good at rye and hairy vetch cultured group. Leaf length of ginseng under the shading net of a three-layered blue and one-layered black polyethylene net (TBOBPN) was good at barley and hairy vetch cultured group. Meanwhile, leaf width was good at hairy vetch cultured group. Leaf length of ginseng under a blue polyethylene sheet (BPS) was good at a barley and barley + hairy vetch cultured group, but stem length was shorter compare to other shading net cultivations. Root weight of ginseng was good under the shading net of a two-layered blue and two-layered black polyethylene net (TBTBPN) at a rye and hairy vetch cultured group, and was good under the shading net of a three-layered blue and onelayered black polyethylene net (TBOBPN) at a barley + hairy vetch cultured group, but there was no significant difference under blackout screen according to manure crop varieties. Ratio of rusty root was 10.2% at the barley cultured group under the shading net of a two-layered blue and two-layered black polyethylene net (TBTBPN), and was 23.1% at hairy vetch cultured group under shading net of a three-layered blue and one-layered black polyethylene net (TBOBPN). Ratio of rusty root was the lowest at a rye cultured group regardless the shading nets. Content of the ginsenoside was the highest at the rye cultured group under the shading net of two-layered blue and two-layered black polyethylene net (TBTBPN), was the highest at the barley cultured group under the shading net of a three-layered blue and one-layered black polyethylene net (TBOBPN), and was the highest at the rye cultured group under the blackout screen.

고추 시설재배지에 녹비작물 재배가 토양의 Arbuscular 균근균(AMF) 포자밀도 및 감염율에 미치는 영향을 구명하고자 보리와 호밀, 헤어리베치, 완두콩을 파종하여 1차 녹비작물 재배 후 토양에 환원하고 고추를 재배한 다음, 2차 녹비작물 재배하여 시설 토양내 Arbuscular 균근균(AMF) 포자밀도 및 감염율을 조사한 결과 AMF포자밀도는 녹비작물 재배지가 대조구보다 높은 경향을 보였다. 기주작물별 AMF활성포자의 밀도는 보리와 완두콩이 호밀, 헤어리베치 그리고 쇠별꽃에 비하여 높았다. 녹비작물의 기주작물별 AMF포자의 형태와 크기는 유의적인 차이가 인정되지 않았다. 녹비작물의 기주 작물별로 뿌리 내 AMF 감염율을 조사한 결과 보리녹비작물에서 감염율이 높았으며 녹비작물의 감염구조는 뿌리내부 균사임이 확인되었고 AMF 균사의 Network도 매우 발달되었다.

This study was conducted to evaluate soil nutrient concentrations and N uptake efficiency of paddy rice as affected by nutrient sources from 2009 to 2011. The treatments included chemical fertilizer, compost, oilcake, oilcake 2X, hairy vetch, vetch+rye, and control. Nutrient applications were made at rates equivalent to approximately 90 kg of actual N per hectare. Oilcake had the lowest C:N ratio from the raw materials, but compost had the highest C:N ratio of 34:1. Soil pH and concentrations of C, N, Ca, and Mg were unaffected by nutrient source treatments. N uptake efficiency was the greatest for oilcake-treated rice compared to those treated by NPK, hairy vetch, and compost in 2009 and 2010. Composttreated rice had the greatest N uptake efficiency in 2011 when the high amount of precipitation occurred.

The competition between green manure and forage crops frequently occurred at agricultural field because of soil fertility and livestock feeding selection. These experiments were carried out to evaluate the effects shoot and residue for green manure and forage production by leguminous crops and barley mixtures at paddy. Field experiments were conducted at paddy soil from 2008 to 2009. Treatments consisted of mixture and inter-seeding of barley and leguminous crops (hairy vetch and crimson clover). These treatments were divided into cutting height of 8 and 25 cm for using of green manure and forage at once. The residue biomass of 25 cm cutting height was higher than 8 cm and were no significantly between mixture and inter-seeding. However, residues of legume crop were significantly higher at inter-seeding than mixture. The shoot biomass of 8 cm cutting height was higher than 25 cm for forage using. The production of legume crop was high at the barley and hairy vetch seeding plot. The mixture of hairy vetch and barley showed the best biomass of shoot and residue for green manure and forage using at 25 cm of cutting height. Also this treatment could be possible to rice cultivation by no fertilization. Therefore, we suggested that 25 cm cutting of hairy vetch and barley mixture could be used for green manure and forage at the same time under rice-based cropping system.

BACKGROUND: Soil incorporation of green manure crop(GMC) and liquid pig manure(LPM) is one of the methods for reduction of chemical fertilizer and the increase of crop yield. The objective of this study was to select optimal incorporation time of GMCs on growth and nutrient property in paddy soil treated LPM. METHODS AND RESULTS: The kinds of GMCs were Hordeum vulgare L.(green barley, GB) and Vicia villosa roth(hairy vetch, HV). The effects of GMCs on rice yield were investigated under different incorporation times of GMCs(LPM1: at 25 days before rice transplantation, LPM2: at 18 days before rice transplantation, LPM3: at 11 days before rice transplantation). In GB treatments, the biomass was greater in the order of $$LPM3{\geq_-}LPM2{\geq_-}LPM1$$. Contents of N, P and K ranged 1.21~1.28, 0.36~0.38 and 1.41~1.45%, respectively, regardless of incorporation times. The amounts of nutrient supply in GB treatments were higher in LPM1 than those in other treatment conditions. In GB treatments, rice yields in LPM1, LPM2 and LPM3 were 523, 525 and 526(increasing yield 3% than control) kg/10a, respectively. In HV treatments, the amounts of nutrient supply were higher in the order of $$LPM3{\geq_-}LPM2{\geq_-}LPM1$$. Rice yields were 530 kg/10a for LPM1, 531 kg/10a for LPM2, 535 (increasing yield 5% than control) kg/10a for LPM3 in HV treatments, respectively. CONCLUSION(s): The optimum incorporation time of green barley and hairy vetch was at 11 days before rice transplantation(LPM3) in paddy soil with liquid pig manure.
