  • Green manure crops have been well recognized as the alternative for chemical fertilizer, especially N fertilizer, because of its positive effect on soil and the environment. Hairy vetch and green barley are the most popular crops for cultivation of rice in paddy field. This study was conducted to evaluate effects of hairy vetch and green barley on soil microbial community and chemical properties during short-term application (three years). For this study, treatments were composed of hairy vetch (Hv), green barley (Gb), hairy vetch + green barley (Hv+Gb), and chemical fertilizer without green manure crops (Con.). Hv+Gb treatment showed the highest microbial biomass among treatments. Principal component analysis (PCA) showed that PC1 (73.0 %) was affected by microbial biomass and PC2 (21.5 %) was affected by fungi, cy19:0/18:$1{\omega}7c$ (stress indicator). Combined treatment with hairy vetch and green barley could be more efficient than green manure crop treatment as well as chemical fertilizer treatment for improvement of soil microorganisms.

  • 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.

  • Background: The study aimed to obtain data on the effects of cultivation and soil reduction of green manure crop on the quantity and quality of organically cultivated Cynanchum wilfordii Hemsley. Methods and Results: The experiment comprised four treatments: control, hairy vetch, barley, and hairy vetch + barley (3 : 2). The plant height in the hairy vetch treatment (86.3 cm) was significantly different from that in the other treatments, whereas the stem diameter leaf area, and special product analysis division (SPAD) value did not differ across the treatments. The largest soil reduction of green manure crop was recorded in the barley treatment (440 kg/10 a), whereas the smallest was recorded in the single treatment with hairy vetch (80 kg/10 a). The hairy vetch + barley (60 : 40) treatment showed 63% more soil microorganisms than control. Radical scavenging activity estimation revealed that the total polyphenol content was highest (1,740 mg/kg), and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) was 92.6% in the barley treatment. The 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) activation was highest in the control (51.1%), and the root yield was the highest in the barley treatment (310 kg/10 a). Conclusions: The root yield, total polyphenol content, and antioxidant activity of Cynanchum wilfordii (Maxim.) Hemsley increased in presence of the green manure crop barley.

  • The application of liquid swine manure to soil has been commonly reported to increase crop productivity by improving plant nutrient availability. This study was conducted to investigate the effect of liquid swine manure (LSM) application on yield of green manure crops in paddy. Three different application rates of LSM equivalent to 25%, 50%, and 75% of standard fertilization rate of P were applied to the paddy field after rice harvest, and two cover crops, hairy vetch (Vicia villosa Roth) and barley (Hordeum vulgare L.), were subsequently mix-seeded and cultivated. Plant height of barley was 7% higher in LSM P25% and LSM P50% compared to control treatment (no LSM application), while no significant difference was observed between LSM P75% and control. However, there were no significant differences in plant height of hairy vetch among treatments. Dry matter (DM) yield of green manure increased with LSM application rate, reaching a maximum at LSM P50% (38 and 17% yield increase over control for hairy vetch and barley, respectively), but it decreased at LSM P75% rate. Nitrogen production by green manure crops was the highest in LSM P50% treatment, where the amount of produced N was 57% higher than the optimum N fertilization level for rice ($90kg\;N\;ha^{-1}$). Excess green manure biomass above an optimum level can be removed and utilized either for incorporation into nearby cropland or for sale as fresh forage. Therefore, it is concluded that the application rate of LSM P50% is recommendable for the maximum biomass and nitrogen production from green manure crops in paddy.

  • This study was conducted to find optimum mixed sowing ratio of green manure crops to reduce the use of chemical fertilizer as well as to increase the crop yield potential which will foster the utilization of green manure crops in the upland field in view of environment friendly agriculture. According to the study, the mixed ratio, 50:50, of hairy vetch and green barley showed highest nitrogen production yield in the soil due to the relatively higher organic nitrogen supply from the hairy vetch plant as well as nitrogen fixation from the air rather than other mixed ratio. In the 50:50 mixed ratio of hairy vetch and green barely total nitrogen amount in the soil showed 17.2kg per 10a, but in the other treatment ratio such as 75:25, 25:75. total nitrogen fixation amount were 16.7, 16.9 respectively. We also conducted the experiment to compare the effect of the mixed sowing treatment of green manure crops on the production of corn cultivated as a succeeding plant of hairy vetch. According to the result, the mixed ratio, 50:50, of hairy vetch and green barley treatment showed highest yield potential of corn as 153kg per 10a in seed weight which is due to the relatively higher organic nitrogen supply from the hairy vetch plant as well as nitrogen fixation from the air rather than other mixed ratio. In the mixed sowing treatment of hairy vetch 100 and barley 0 ratio, the corn production showed 148kg per 10a which is 5kg lower than that of hairy vetch 50 and barley 50 ratio, but showed statistically no difference between those two treatment. Otherwise, different treatments, such as hairy vetch 75 and barley 25, 25 and 75, 0 and 100 showed statistically different each other. Therefore, it was concluded that green manure crops, such as hairy vetch, green barley and rye were very effective crops to increase the soil fertility and gave the positive effect to the crops to give vegetative and propagative growth condition and, in turn, increased the yield potential. We have to make policy to enhance the utility of green manure crops in the upland crops as well as faddy field for the soil fertility and crop yield production which will guarantee prominent quality of environment friendly agriculture products.

  • Viral infections and root growth were examined to elucidate the relationship between viral resistance and root growth in 26 Korean hulless barley cultivars. Viral resistance was estimated in experimental filed of Honam agricultural research institute for 3 years. Length and number of seminal and adventitious roots were examined for evaluation of root growth in both field and green-house conditions 30 days after seeding. Dominant viral infection occurred in Korean hulless barley by Barley yellow mosaic virus (BaYMV) in fields; however, susceptible cultivars were infected by either BaYMV, Barley mild mosaic virus (BaMMV) or both. Only four cultivars, including Donghanchalssalbori, Kwangwhalssalbori, Namhossalbori and Naehanssalbori, presented stable resistance to viral infections. Susceptible cultivars to viral infection in fields showed shorter seminal root length and fewer adventitious root number than resistant cultivars. Resistant cultivars showed better root growth and significant difference in adventitious root length in green house conditions. Increase in the number of seminal roots in resistant cultivars was derived from decreased damage of roots by the viral infection compared to the susceptible cultivars.

  • It is known that the poor soil fertility of newly reclaimed saline soils is due to the lack of organic matter and available mineral nutrients for crop production. The effect of green manuring with Sesbania aculeata in combination with five rates of urea-N treatments (N0. N25, N50, N75, N100) on the productivity of a subsequent whole-crop barley and the fertility of the reclaimed saline soil in Saemangeum was evaluated in the field during 2013-2014 growing season. Sesbania was grown during summer season (June to October). The amount of Sesbania incorporated was $16.2Mg\;ha^{-1}$. Sesbania contributed to $393kg\;N\;ha^{-1}$ to the soils when ploughed down and incorporated before whole-crop barley cultivated. The performances of whole-crop barley following sesbania incorporation were significantly affected by a combination of Sesbania manuring and different N rates. The N fertilizer equivalence without N fertilizer following Sesbania was 42.6% ($63.9kg\;N\;ha^{-1}$), compared with N100 ($150kg\;N\;ha^{-1}$) in fallow soils. The whole-crop barley yield responded to N fertilizer rates in both sesbania-amended and fallow soil. The yield response to nitrogen rates in fallow soil was linear (Y=0.0586X+3.3011, $R^2=0.9534$), whereas that in sesbania-amended soils was quadratic (Y= -0.001X2+0.1322X+5.7143, $R^2=0.9576$). The yield of whole-crop barley in sesbania-amended with increasing N rates was increased up to SN75 (115 kgN) $10.3Mg\;ha^{-1}$. Apparent N recovery (ANR) of whole-crop barely showed decreased with sesbania plus increasing rates of N fertilizer. Despite higher yield with sesbania manuring plus increasing N rates, the contributions of N from Sesbania with increasing N rates to whole-crop barley were decreased, whereas those from fertilizer increment due to excessively mineralized Nitrogen. Considering yield, ANR, N contribution from Sesbania and nitrogen fertilizer, the optimum N rate was N50 rate following sesbania incorporation.
