The top country of organic agriculture becomes nowadays well known Germany in terms of technical levels not only in the field of organic plant & animal production but also food processing & marketing. In this paper, 3 main factors which exerted a strong influence on the evolution & development of German organic agriculture in Germany were discussed.First, German Universities such as University of Bonn, University of Giessen, and Hohenheim University established Dept of Organic Agriculture and offers the organic agriculture major in the Master & Ph D course, while University of Kassel established College of Organic Agriculture and offers 23 major courses in various organic agriculture sectors. Furthermore most agriculture colleges in Germany offers some organic agriculture subjects to the students, because organic agriculture is one of the emerging industries in the agricultural sector, and farmers and consumers pay a great attention. There are 50 universities which offer agriculture courses in Korea, nevertheless none of Korean university offers Dept of Organic Agriculture. Second, German federal government established National Institute of Organic Agriculture in Trenthorst and tried to develop new scientific technology and skills for organic plant and animal production. And these new technical information was transferred to organic farmers through Demonstration Farm which is located in more than 200 sites. Third, Organic Agriculture Extension Service Center such as Kompetenzzentrum Oekolandbau Niedersachen (KÖN) was established in each states from 2002. These Organic Centers offer various advices for organic farmers verified scientifically or and the technical package for conversion farmer too.

Agricultural production is the most important sector, because it supplies human food, clothing, medicine, employment, etc. In order to promote development as well as investigation into agriculture, it is critical to master into any agricultural systems all over the world. This study is to capture comprehensive understanding on the status of Vietnam’s agricultural production, trade and policies. Vietnam is an agricultural country with a long history of Wet Paddy Civilization where agriculture sharing 35.1% of land area, employing 42% of labors and contributing up to 17% of total 196.3 - billion$ GDP in 2015. During the last 30 years of implementing Doi Moi Policy, a market orientation reform. Vietnam has achieved remarkable results for ensuring national as well as global food security, eliminating hunger, alleviating poverty. The country has transformed from one of the world’s poorest to a lower middle-income country (1,990 $/capita in 2015) with high exporting quantities of agricultural products for being the world largest exporter of cashews nut and black pepper, the second largest exporter of coffee and cassava, and the third largest exporter of rice in 2013. The nation has boosted its international economic integration with more than 100 different trading partners all around world, which has provided a further catalyst for national economic development. However, the country is still facing with many challenges in agricultural production. Hence, the country has made big efforts to restructure its agriculture. Production is oriented towards agriculture commodities with intensive cultivation and specialization to boost productivity and quality, using more machinery, agricultural materials, high technologies, and agriculture associated with industrial processing and agricultural services.

The potato production area in Mongolia can be divided into four regions such as central agricultural region, western agricultural region, eastern agricultural region, and gobi agricultural region based on climate and soil conditions. The potato cultivation area increased by over two times for twenty years from 7,806 ha in 1994 to 16,821 ha in 2012. Amounts of potato production also increased by over four times from 53,957 tons in 1994 to 245,935 tons in 2012. The average yield per ha increased by about 8 tons, 15.0 ton/ha in 2012 more than 6.9 tons/ha in 1994. This result is attributed to successful supply of virus-free seed potatoes through the ‘Mongolian Potato Program’ (MPP). The potato import volume decreased dramatically from 35,884 tons in 2008 to under 34 tons in 2013 and the export volume was 3,500 tons in 2013 and 4,800 tons in 2014. Potato breeding program in Mongolia began in the relatively recent years and the important selection criteria were yields, drought tolerance, early maturity, and deep yellow skin and flesh colored variety. The seed potato systems have been improved as follows: traditional clonal selection system(1974-1976), virus free tissue culture system(1988-1990), and MPP seed system( 2004-2008). In the future in Mongolia, combined potato processing facilities are needed for the overproduced potatoes. The official development assistance (ODA) fund being supported for 12 years was stopped along with MPP project termination in 2015, so Mongolia is faced with the difficulty that have to maintain the seed potato system by itself.

The core principles of Korea’s Saemaul Undong, a model of the agricultural and rural development for developing countries, may be summarized as adoption of organizational approach considering spiritual enlightenment, pursuit of visible change through practical innovations, villager’s voluntary participation and self-help, and introduction of competition-based incentive system. The contents of the Saemaul Undong project include agricultural production technology transfer and agricultural infrastructure building as well as spiritual enlightenment and living infrastructure improvement. Based on the situational characteristics of Myanmar, some measures to apply Saemaul Undong approach can be proposed as follows. The scope of Saemaul Undong needs to encompass agricultural technology transfer as well as infrastructure building for improving agricultural production and living environment. Saemaul Undong is not a panacea for rural development, but it can be a guide for developing agriculture and rural areas by helping lessen trial and errors. Mind-set change by Saemaul Undong training and group decision making with village leaders and villagers need to be actively applied to Myanmar. Emphases need to be put on agricultural productivity and income increase as well as living environment improvement considering unique situations of Myanmar. In addition, income increase measures for landless farmers by livestock raising are required. Empowerment, manpower mobilization and material support need to be flexibly applied to rural villages based on their labor market situation. In developing village leaders, partnership with NGOs needs to be emphasized in suburban areas. Systematic evaluation tools need to be developed for identifying determinants of the success of Saemaul Undong.

In January 2016, Korea began rice exporting to China from six domestic Rice Processing Complexes (RPC). The appearance characteristics and quality of medium-short grain milled rice between the exported Korean rice was compared with Wuchang rice, which is known as high quality in Heilongjiang province in China, and the imported rice from Japan and Taiwan in Chinese circulating marketing. The 1000-grain weight of exported rice is 22.4g, which is similar to that of Chinese Wuchang rice, but it tended to be heavier than that of Japanese and Taiwanese. The rice type is round in exporting Korean, Japanese, and Taiwanese rice while Chinese Wuchang rice is thin and long with 2.5. The head rice rate of export rice was 93.3 ~ 98.4%, which was 95.8% on average, which was higher than that of Chinese Wuchang rice, and similar to that of Japanese, and Taiwanese. The protein content of the export rice was 5.2 ~ 6.2%, which was 5.8% on average, similar to that of Chinese Wuchang rice, Japanese and Taiwanese. Amylose content was 18.5% of the exported rice, which was lower than that of Chinese Wuchang rice and slightly higher than that of Japanese and Taiwanese. The whiteness of the exported Korean rice was 35.6 on the average, lower than 41.8 of Chinese Wuchang rice, and lower than that of Japanese and Taiwanese. The purity of rice variety being exported ranged from 87.5 to 100.0%, which was 96.5% on average. This was much higher than that of Chinese Wuchang rice, while the Japanese and Taiwan rices were similar. The sensory test of rice by the experts, cooked rice of the exported was evaluated to be good for all items such as taste, sticky glutinous, and texture compared to Chinese Wuchang rice.

Teosinte, commonly known as wild species of corn, has distributed in Central and South America. It is believed that teosinte contains genes for resistance to flooding because of the climate characteristics of the collected countries. Recent studies have shown that teosinte has the ability to form adventitious roots, to develop aerenchyma tissues of teosinte, and the resistance to toxic substances under flooding soil condition. Therefore, development of corn varieties to cope with climate change and the growing corn at paddy field in Korea are required to introduce the characteristics of teosinte. However, in order to utilize teosinte resources, preconditions must be settled such as photoperiodic responsibility, physiological and ecological characteristics. Also if the preconditions are studied together with the metabolic level studies, the possibility of utilization for flooding resistant varieties will be even higher.

During the harvest season, drying and storage facilities at Rice Processing Complexes (RPCs) are not enough to manage all the harvested rice, which causes quality deterioration and decomposition. Also, rice export is being limited due to the high cost of long-term storage for shipping. This study was conducted to investigate the germination rate, fat acidity and lipoxygenase activity of brown rice after storage of 3, 6, 9 and 12 months at 25oC and 35oC with 22 Korean and 2 Japanese varieties. Germination rate of rough rice was decreased to 72% after storage of 9 months at 25°C and decreased to 35 and 33% after 3 and 6 months at 25°C, respectively. Fat acidity was increased according to storage periods and increasing level was higher at 35°C than at 25°C. Lipoxygenase activity was decreased according to storage periods and decreasing level was higher at 35°C than at 25°C. Although the protein content was not significantly different according to the storage period at both 25 and 35°C, significant difference existed among cultivars. Amylose content was increased until 6 months at both 25 and 35°C, but decreased after 9 months. Fat acidity and protein content were negatively correlated with amylose content, while amylose content was positively correlated with lipoxygenase activity after 12 months at 25°C. Germination rate was negatively correlated with fat acidity and protein content, while fat acidity was positively correlated with protein content and negatively correlated with amylose content and lipoxygenase activity after 6 months at 35°C. 24 varieties were classified into 3 groups on the basis of germination rate, fat acidity and lipoxygenase activity after 12 months at 25°C and 6 months at 35°C. Group I including 8 varieties of Koshihikari showed higher germination rate, lower fat acidity than Group II including 11 varieties of Nampyeongbyeo.. Honong and Jinbaek. Hopyeongbyeo and Hopum showed higher germination rate, lower fat acidity at 35°C than 25°C, while Hwanggeumnuri showed higher germination rate, lower fat acidity at 25°C than 35°C.

DNA-based markers have been used in various fields like molecular biology and crop breeding program. DNA marker is able to be used for protection of genetic resource and quantification of specific cultivar. Eleven DNA markers have been developed for Korean wheat cultivar identification in 2013-2014. 27 of 32 wheat cultivars were distinguished by 11 DNA markers. In this study, we developed four DNA markers, KWSM0012, KWSM0013, KWSM0014 and KWSM0015, derived from SSR and SNP analysis. Consequently, 32 Korean wheat cultivars were identified by 15 DNA markers. We are convinced that these new DNA markers are very useful for wheat varieties DNA fingerprinting and are able to be applied to marker-assisted selection in wheat breeding program in Korea.

Sweet potato [Ipomoea batatas (L.) lam] plant is known to have the relatively tolerance soil moisture deficit compared to other upland crops. However, recently, it has been causing plant growth inhibition and decrease storage quality due to the drought during the growing season of sweetpotato in Korea. The response of root elongation, leaf and shoot growth of sweet potato plantlets, cultivated under different water potential conditions were observed. Six varieties, such as yellow fleshed (Jinhongmi), dark-yellow fleshed (Daeyumi), dark-orange fleshed (Juhwangmi), light-orange fleshed (Dahomi, Pungwonmi), and purple fleshed (Sinjami) were used in this experiment. Using the follow water osmotic potential (WOP) levels were 0 (control), -0.05, -0.1, -0.2, -0.3, -0.4, -0.5 MPa by polyethylene glycol (PEG). In in vitro culture condition, ‘Jinhongmi’ has been inhibited rooting number and number of leaves less than 2, although slightly low WOP of–0.05 and –0.1 MPa, and at –0.2 MPa. shoot was not growing. ‘Daeyumi’, Dahomi, and Juwhangmi’ produced 2 roots as a low WOP of –0.3 MPa. and at –0.2 MPa., it appeared 2 or 3 leaves. ‘Pungwonmi’ produced similar to root number 3.9 at –0.1 MPa compared to control, but root weight decreased 75% at - 0.1 MPa more than control. Root did not grow at – 0.2 MPa for ‘Sinjami’. In nursery bed culture condition, roots fresh weight, number of leaves, and shoot length were inhibited according to the decreases of water osmotic potential. In the case of leaf area, ‘Jinhongmi’ and ‘Daeyumi’ was a significantly difference to 8.4, 22.6 cm3 at –0.2 MPa compared to control, respectively. No difference were obsered for ‘Dahomi’ at -0.1 and –0.2 MPa. ‘Pungwonmi’ was decreased 86% at -0.1 MPa compared to the control. ‘Juhwangmi’ and ‘Sinjami’ was a significantly difference to 15.5, 3.6 cm3 at –0.1 MPa compared to control of 22.9, 16.8 cm3, respectively.

This study conducts a comparative analysis on the difference in profitability between organically cultivated ginseng and conventionally cultivated ginseng, based on their cultivation characteristics, in order to promote the production and consumption of organic ginseng. The production quantity of organically cultivated ginseng per 10 a was 40% less than that of conventionally cultivated ginseng for both four- and six-year-old roots. In the case of four-year-old roots, although the production cost of organically cultivated ginseng was 60% higher than that of conventionally cultivated ginseng, the net profit was higher by 70%, owing to its higher selling price. In the case of six-year-old roots, the production cost of organically cultivated ginseng was 10% higher than that of conventionally cultivated ginseng, but the net profit was lower by 10%, owing to a low selling price. The reduction in production costs must be supported by a reduction in land lease and labor costs by expanding the cultivation area, a reduction of pest control costs through the self-production of environmentally friendly materials, and an improvement in the certification of perennial crops that can reduce certification costs. A reduction in production costs can lead to a decrease in consumer prices, which, in turn, would promote an increase in consumption among general consumers. Moreover, as a measure to increase the production yield per unit area, the soil nutrient content must be increased by selecting high-quality planned sites and implementing planned site management in order to increase the proportion of organic fertilizers. Furthermore, these must be supported by improved cultivation methods, which suppress early defoliation, and enhanced cultivation technology. In addition to these methods, establishing producer cooperatives in order to expand production can stabilize supply, which can increase sales through export and processing companies. Moreover, uniformity in product quality through producer cooperatives can contribute to building consumer confidence.

Crude extracts from several medicinal plants were investigated for their antimicrobial activities against Colletotrichum spp. in grapevines Extracts of sweet wormwood, cockscomb flowers, asian plantain flowers, and peach tree resin showed in vitro antifungal activity on growth of Colletotrichum acutatum. To test inhibition effects of ripe rot development by C. acutatum and C. gloeosporioides, grapevine leaves were sprayed with each extract (500 fold diluted) from sweet wormwood and cockscomb flower and leaves, asian plantain flower and peach tree resin. The crude extracts of medicinal plants displayed remarkable in vivo antimicrobial activities with inhibition of lesion development by 22.5 to 67.5 % in ‘Blanc seedless’ and 2.12 to 53.2% in ‘Thompson seedless’ inoculated with agar block of C. acutatum and by 19.2 to 61.5% in 'Blanc seedless' and 19.6 to 78.3% in ‘Thompson seedless’ grapevines inoculated with spore suspension of C. acutatum compared with the untreated control. The crude extracts of medicinal plants showed remarkable inhibition of ripe rot by 26 to 64.8 % in ‘Blanc seedless’ and 25.5 to 76.5% in ‘Thompson seedless’ grapevine leaves inoculated with C. gloeosporioides agar block inoculation and by 23.1 to 61.5% in 'Blanc seedless' and 18.8 to 25% in ‘Thompson seedless’ grapevine leaves inoculated with C. gloeosporioides spore suspension compared with uninoculated control. These findings indicate that medicinal plant extracts could be used as possible candidates to control ripe rot disease environment friendly in grapevines.

In order to evaluate CMV resistance of the radish inbred lines, leaves of twenties radish (Raphanus sativus L.) inbred lines were mechanically inoculated with a strain of Cucumber mosaic virus (CMV) systematically infecting radish plants, respectively. The inoculated radish plants were incubated at 22°C±3°C and resistance assessment was examined using symptom development for 4 weeks. Based on the reactions of differential radish inbred lines, 11 radish lines were produced mosaic, mottling, yellowing and severe mosaic symptoms by CMV infection. These results were confirmed by RT-PCR analysis of CMV coat protein gene, suggesting that CMV is responsible for the disease symptoms. In contrast, 9 resistant radish lines did not induce systemic mosaic symptoms on upper leaves and chlorosis in stem tissues for 4 weeks, showing that the radish plants did not express any symptoms by 8 weeks. Further examination of CMV infection in the 9 resistance-candidate radish lines showed no CMV infection in systemic leaves of the 9 radish lines. Taken together, these results suggest that the 9 radish lines are highly resistant to CMV.

This study was accomplished to investigate the effects of the night temperatures on the dark respiration and fruit quality of ‘Heukgoosul’ grape at ripening time. The weight of cluster and berry increased significantly at 20oC than 30oC in night temperature. The length and diameter of berry harvested from the 20oC and 25°C treatments also increased significantly. But there were no differences in the cluster length and diameter as well as the number of berries per cluster. When the amount of CO2 uptake was examined, the dark respiration decreased at 20°C in comparison with 30°C. On the other hand, the anthocyanin content of fruits harvested from the 20°C treatment was higher 38.8 μg·cm-2 than that of 30°C 27.7 μg·cm-2. Hunter’s value such as L(brightness), a(red chromaticity) and b(yellow chromaticity) showed the significance between 20°C and 30°C treatments. Soluble solid content and acidity of berry fruits harvested from the 20°C treatment increased respectively by 3.4 °Brix and 1.6 times. With consideration of the main characteristics of fruit harvested at 30°C, the sugar-acid ratio 72.6% was lowered and the color chart showed the low value 7.1, therefore, the overall fruit quality was deteriorated. When the production yield rates of first harvest 23.6% and second harvest 44.7% were compared, the 20°C treatment could move up the harvest time earlier.
