To investigate the optimum harvesting time of rice from June to December 2015 at Yezin in Middle plain area of Myanmar. The rice cultivars tested were Dasan2, Yeongpungbyeo(Korean cultivars) and Shwe Thwe Yin(Myanmar cultivar). The ripened grain rate were high when the harvesting date after heading were between 35 and 40 days for Dasan2, Yeongpungbyeo and between 30 and 35days for Shwe Thwe Yin, respectively. The highest yield of rice was obtained when harvested 35 to 40days after heading for all cultivars. However, the shattering loss was the highest in 40days after heading, the yield losses in 40DAF(days after flowering) are 2 to 2.7 times more than other treatments in 30DAF. Therefore, the estimated optimum harvesting times are 40DAF, 31DAF and 25DAF for Dasan2, Yeongpungbyeo and Shwe Thwe Yin, respectively.

Operating Cases of Farmer Organizations in the Rice Industry of Korea and Its Implication for Uganda
South Korea and developing countries like Uganda have sought to re-energize their agriculture sector growth using 6th Industrialization of Agriculture strategies. These strategies seek to upgrade farming households from just being producers or primary industry players to participants in the secondary and tertiary industry. This convergence is known as 1x2x3 = 6th Industrialization. This involves farmers strengthening production and investing in higher value chain activities such as agrotourism, agro-processing, farm restaurants, and the export market. These developments are driven by investment in institutional arrangements and technology that is often beyond the capacity of individual farming households as well as some farmer organizations and cooperatives. Qualitative approaches were used to draw lessons from two typical rice farmer organizations and two rice value addition groups and other sector players to investigate group formation dyanamics and the capacity of farmer organizations to attain goals for grouping. The results show being a member of a farmer organization increases access to inputs such as machinery, however, the key determinant to joining is trust/mistrust of leadership. In regard to attainment of 6th Industrialization, farmer organizations still have to hassle with uncertainty of marketing a new 6th industry product. Nevertheless farmer organizations seem closer to attaining the 6th industry goal due to exposure to primary processing and export business. Some implications have been drawn for Korea as well as localization to Uganda’s situation.

Buckwheat is a major food crop with a world production of 1.9 million tons. This study analyzes the domestic and overseas production trends of buckwheat and presents supply and demand forecasts to provide basic data for stable production of buckwheat. Asia has the largest cultivated area of buckwheat and its production has been increasing not only in Asia but also in Europe. Notably, the trend of buckwheat production is steadily increasing in the Americas and some African countries. The top 5 producers of buckwheat are Russia, China, Ukraine, France and Poland. In particular, China and Russia accounts for 64% of the total production. Among the 28 producing countries, Korea placed 11 ~ 17th in production rank, which is at the middle of the total countries. In Korea, the cultivation of buckwheat started in 1961 covering 21,548 ha, and peaked at 27,417 ha in 1968, but then decreased to 2,095 ha in 2014. However, in 2016, the cultivated area has slightly increased to 3,177 ha. The recent interest in health foods has raised the domestic demand for buckwheat. The annual consumption of buckwheat per capita in 2016 is 80 g, and domestic self-sufficiency rate is 62.2% in 2016 which is higher than other grains. Buckwheat is currently consumed in the form of flour, buckwheat groat, etc., including noodles, which accounts for more than 96% of the total processed form of buckwheat. The market for buckwheat is expected to expand with the creation of buckwheat beverages with high added value like buckwheat tea.

This paper describes Philippine farmers’ perception on farm mechanization and land reformation. For a survey, 280 farmers were interviewed. According to the survey, Philippine farmerrespondents seem to recognize the many advantages of using farm machines over manual, even if these are expensive and will certainly displace laborers. Although land reformation is known to only one third of the farmers, they understand it as a way of re-structuring roads and fields, and will ease farm management. Philippine farmers’ awareness of farm mechanization and land reformation appears to be very low and they also have financial problems when they consider to adopt farm mechanization and land reformation. Therefor, it is very essential to raise farmer’s awareness and also provide financial subsidy to farmers who have willingness to adopt mechanization and land reformation. Also introduction of farm land bank system like korean experience is recommended as one of alternatives.

This study was conducted to clarify the effect of high temperature during winter period(autumn sowing) and spring sowing on yield, quality and growth and development in barley. The varieties used for the experiments were heenchalssalbori and keunalbori 1 having a strong spring habit characteristics. In spring sowing treatment, spikelet differentiation was proceeded rapidly and tillering was proceeded slowly compared to the development stage, because the barley sowed at spring is cultivated in high temperature and long day conditions from sowing to spikelet differentiation stage compared with autumn sowing(control). And in high temperature treatment during winter period, like spring sowing, tillering was inhibited compared to the development stage. The number of grain per panicle and the period required to heading stage from spikelet differentiation were reduced largely at spring sowing, because spring sowing treatment was conducted in high temperature and long day condition compared with autumn sowing and high temperature treatment during the period from spikelet differentiation to heading stage. Meanwhile in spring sowing treatment, average temperature during ripening stage was higher than the autumn sowing and high temperature during winter, because heading stage was so late. After all, starch, amylose content and grain weight were reduced while protein content was relatively increased in spring sowing treatment due to difference of average temperature of ripening stage. These changes affected the decrease of viscosity of peak, trough, breakdown and the increase of setback viscosity

This experiment was performed to analyze the annual variation of growth traits of soybean to determine the information of less sensitive traits and stable cultivars based on the environmental conditions. Sowing was carried out on June 2 for each year and the test plot was arranged in three replicates by randomized complete block design with thirty soybean varieties including two landraces during the period 2014-2015. The weather conditions during the test period were quite different with extremely low precipitation and longer sunshine duration in 2015. The variation of characteristics related to growth period such as days of growth, days of maturity, days of flowering and 100-seed weight were less in spite of different environmental conditions. While the variation of the number of pods per plant was high. Considering growth and seed characteristics like the number of pods per plant, the number of seeds per pod, and 100-seed weight which are linked directly to the yield, cultivars such as Shingi, Daewonkong, Danbaegkong, and Daepung for beancurd and soypaste, Pungwon, Haepum and Shingang for soy-sprout and Seoritae for cooking with rice were more stable and are expected to have high yield in Suwon, the south-central part of South Korea. These results are useful for the selection of breeding resources to develop cultivars with high stability under changeable weather condition.

In Korea, 1,212 accessions of garlic are conserved in Namhae, Jeonju, Danyang and Muan with IT (Identity) number. This study was carried out to evaluate characteristics of 163 garlic cultivars conserved in Namhae branch, NIHHS, RDA and search valuable genetic resources for breeding. In horticultural characteristics, there was wide variation for bulb weight, clove weight and clove number per bulb with large coefficient of variation (CV) 40.04%, 43.98% and 39.64% respectively. Alliin content analyzed by HPLC was 16.75±6.22mg·g-1 DW (Dry weight) and had 37.16% CV. The highest alliin content was 32.27mg·g-1 in Local5. In correlation analysis, there were a strong positive correlation between bulb weight and bulb diameter and a non-correlation between clove number per bulb and bulb weight, height and diameter. Major characters included in the principal components were bulb weight, bulb height, bulb diameter, plant height, clove number per bulb, leaf sheath diameter and alliin content. According to characteristics of garlic, 163 germplasms were clustered into 10 groups. In total 10 clusters, the average bulb weight is the heaviest at 5th cluster and average alliin content is the highest at 4th cluster. These clusters will be used for selection breeding program to cultivate garlic that has heavier weight and high alliin content.

In Korea most bulbs of calla lily (Zantedeschia spp.) are imported from foreign countries including USA and Netherlands due to frequent viral infection problems in field propagation. To solve this problem, in vitro propagation system of calla lilies has been attempted, which ultimately would have an agronomical impact on Korean calla lily farmers. In this study, we carried out experiments to find an efficient method for multiple shoot formation and subsequent root induction in calla lily ‘Black Star’. Lateral buds were used for the induction of multiple shoots on basal MS media containing various concentrations of auxin and cytokinin. The highest callus and multiple shoot formation was observed in MS medium containing 1.0 mg/L of each NAA and BA, in which 25 (83.3%) explants exhibited callus formation and all 30 explants produced multiple shoots with an average of 14.7 shoots per explant in average length of 4.1 cm. Subsequently, obtained shoots were tested for root induction in MS media containing auxins, IAA, NAA, or 2,4-D, because calla lily shoots derived from tissue culture did not produce sufficient roots that are crucial for the survival under natural environment after transplanting. An average of 4.9 or 3.1 roots was generated after 20-day culture of shoots on MS media containing 1.0 mg/L IAA or 1.0 mg/L 2,4-D, respectively. However, no root formation was observed in MS media supplemented with NAA, indicating that NAA is not adequate for root induction of shoots derived from tissue culture of ‘Black Star’.

We screened 108 cultivars of grapevine (Vitis spp.) for resistance to grape ripe rot, caused by Colletotrichum acutatum and C. gloeosporioides. We evaluated the resistance to ripe rot of berries and vine leaves from grape cultivars by measuring the lesion size after inoculation with C. acutatum and C. gloeosporioides. ‘Aki Queen’ (Table grape) and ‘Cabernet Sauvignon’ (Wine grape) were shown to be moderate resistant against inoculation of C. acutatum both in berries and leaves. ‘Emperatriz’, ‘Honey Red’, ‘Honey Venus’, ‘Izumo Queen’, and ‘Rosario Rosso’ in table grapes, and ‘Cabernet Sauvignon’, ‘Chancellor’, ‘Chardonnay Decoupe’, and ‘Ventura’ in wine grapes, were shown to be resistant to C. gloeosporioides both in berries and leaves of them. Grape cultivars were classified into four classes based on its level of resistance to C. acutatum and C. gloeosporioides. The present data for determining ripe rot resistance will be very useful in developing effective disease management strategies in the vineyards and selecting grape genetic resources to be used in disease resistant grape breeding programs.

An organophosphorus pesticide, ethoprophos, has been widely used in agriculture to control major insect pests. As ethoprophos is a well-known neurotoxin, its accumulation in soils and groundwater is concerning worldwide. In this study, we constructed an artificial ethoprophos-enrichment soil system, and its active concentration in soils was measured by gas chromatography on 15-days intervals during 90 days after ethoprophos treatment. Furthermore, the changes in bacterial community and microorganisms responsible for efficient bioremediation were investigated while ethoprophos was degraded in soils. From 15 to 60 days after the treatment, ethoprophos was actively degraded in soils and members of genera Collimonas and Sphingobium appeared dominantly in a natural microbial community especially in 60-days-after-treatment soil. We isolated a bacterium EP60845 from this soil sample, showing significant ethoprophos biodegradation activity in vitro. When we challenged EP60845 strain into ethoprophos-enrichment soils (250 mg/kg of soil), most ethoprophos was removed within 5-days. Phylogenetic 16S rRNA gene sequence analysis and biochemical properties by API 20GN kit demonstrated that the EP60845 strain was a novel Sphingobium sp., which could be used as an efficient ethoprophos- degrading agents for bioremediation purposes.

The objective of this study was to quantify and characterize the inorganic nitrogen and phosphorus outflow loading from different water managements in paddy fields. We investigated the NO3-N, NH4-N, and PO4 in runoff from paddy fields in Iksan. The three different water management treatments were conventional continuous irrigation at 4 and 8 cm water levels, and intermittent irrigation at a 4 cm water level. The concentration of NO3-N at the early growth stage in surface water was 6.11 mg L-1, and then it gradually decreased. The downward curve increased slightly with additional nitrogen fertilization at the panicle initiation stage, and then it continued to decrease. The NH4-N concentration was 5.26 mg L-1, and that of PO4 was 0.70 mg L-1 at the early growth stage. However, the concentration of NO3-N peaked at 8.79 mg L-1 directly after transplantation and then decreased rapidly throughout the growing season. The amount of NH4-N runoff was 1.86 kg ha-1 in the plot with intermittent irrigation, and 2.0 kg ha-1 and 2.1 kg ha-1 in the plots with water depths of 4 and 8 cm, respectively. The NO3-N runoff was 7.43 kg ha-1 in the plot with intermittent irrigation, 8.62 kg ha-1 in the plot with a water depth of 4 cm, and 10.25 kg ha-1 in the plot with a water depth of 8 cm. In addition, the PO4 runoff was 0.42 kg ha-1 in the plot with intermittent irrigation, 0.48 and 0.55 kg ha-1 in the plots with water depths of 4 and 8 cm, respectively. The saving effect of irrigation water was 28.5% than that of conventional water management treatments, and the amount of nitrogen runoff was decreased by 18.5% with intermittent irrigation. However, the phosphorus runoff was not different between the different water management treatments in paddy fields.
