This study aims to evaluate the enhance policy for paddy soybean production through comparison between Korea and Japansee` supporting policy. The Korean govemment set a goal to increase the self supply rete for food and processing to 50% by paddy soybean cultivation. However, the soybean production was decreased continuously every year, because of lower income than other summer crops and lower price comparability comparing with imported soybeans. We assess that the main cause of failure for the enhance pf paddy soybean production resulred from inconsistent policy which had been discontinued it in 2007 year after puting into force for five years(from 2002 to 2006). On the other Hand, Japanese government have continued to ip to present since setting paddy soybean supporting policy in 1971 year, therefore the cultivated area of soybean production in paddy fields accounts for above 120 thousand ha, about 85% of total soybean area.

Today, there are becoming a spike in interesting due to development of oversea agriculture in Primorsky Krai, the Russian Far East. Republic of Korea provides an opportunity to attract large investments in this sector of the agriculture of the region. Primorsky Krai is one of the most important agricultural belt in the Russian Far East; the Primorsky krai produces rice, soybean, milk, eggs, and vegetables. The Agro-industrial sector of the Primorsky seems one of the most favorable for such mutually beneficial cooperation. Primorsky Krai, bordered by China, North Korea, and the relatively warm, although freezing in winter, waters of the Sea of Japan, is the most southeastern region of Russia, located between the 42° and 48° north latitude. Highlands dominate the territory of the Primorsky krai. Most of the territory is mountainous, and almost 80% of it is forested. The average elevation is about 500 meters. Average annual temperature - near +1℃ in the north of the Primorsky krai; +5.5 ℃ on the southern coast. Soybean is grown from the Equator to latitude 55° N or 55° S and from below sea level to altitudes close to 2000m. The weather conditions of the area are characterized by large imbalance that causes significant inter-annual fluctuations in crop yield. The spatial and temporal changes in climate and weather elements of Primorsky Krai has an important methodological implications not only for the scientific substantiation of soybean crops allocation in the northernmost parts of the global area of distribution, but also for forecasting soybean yield, the adverse weather conditions risk assessments, recommendations on the use of climatic and prognostic information. Because of the farm tractors and field equipment of Primosky Krai are large and heavy, there is a growing concern about soil compaction. Soil compaction can be associated with a majority of field operations that are often performed when soils are wet in spring season and more susceptible to compaction. Heavy equipment and tillage implements can cause damage to the soil structure. Therefore, Soybean growth become the poor on the compacted soil, and as a result, affect seriously on yield losses. Weeds are a major cause of yield losses in soybean field. Primorsky``s Farmers say it is extremely difficult to control Ambrosia artemisiifolia L., common ragweed, in soybean field. We recommend that in order to effective ragweed control, farmers spray soil applied-herbicide “acetochlor” after soybean seeding, and then have a post-emergence herbicide application (mixed with bentazone and acifluorfen) around 30 days after seeding.

The total land area of Paraguay is 406,752 square km. The country is divided in two major geographical regions, with distinct topography and geology, by the south-flowing Paraguay River. There is a pronounced rainfall gradient right across Paraguay. Mean annual rainfall increases from about 400 mm in the north-west to 1,700 mm in the south-east. In the Chaco, about 80 percent falls in summer, whereas in the south-east comer mean monthly rainfall is more equally distributed, with a slight depression in the driest months, July and August. The growing season lasts from October to March in the Chaco. Typical crops are sorghum, cotton and groundnuts. In eastern Paraguay, arable lands are often cropped twice a year under rainfed conditions, with soybean, cotton or maize, followed by a winter crop, such as temperate cereals. Mean annual temperatures vary from 25.9℃ in the north (Bahia Negra) to 21.4℃ in the north-eastern comer of the oriental region (Pedro Juan Caballero). Summers are hot, even very hot. In winter, night frosts (to an absolute minimum temperature of - 6.0℃) occur, except in the extreme north east. Aerial parts of tropical grasses are generally burnt off by frost. Paraguay is the world` s sixth producer and the fourth largest exporter of soybeans. In the past ten years, the area under soy cultivation more than doubled from 1,870,000 ha in 2004 to 3,500,000 ha in 2014. Paraguay` s major soy producing states are Alto Parana, Itapua and Canindeyu, respectively producing 2,036,618, 1,411,313 and 1,401,086 tonnes soybeans per year. The frontiers of soy expansion are moving towards the center of the country, more precisely in Caazapa, San Pedro and Caaguazu. Agricultural products account for 90% of the value of Paraguayan exports, of which about 57% relates to primary export products such as soy beans, meat and cotton (16.6% of GDP).

The objective of this study was to obtain informnation about the relationship between seed coat structure and seed vigor in soybean. The seed coat makes up about 6.0 and 10% of seed weight in the soybean. We observed that the hardness seed had the dosed micropyle and high density of wax material embedded in the seed coat, while normal seeds had the opened micropyle and many large pores on the surface of seed coar in soybean surveyed by scanning electron microscopy. Impermeable seed coat retained viability better than permeable seed under delayed harvest field and poor storage conditions. The soybean seed coat consisted of palisade cell layer, hourglass cells and parenchyma. It is believed that, during slow imbibition, the hourglass and parenchyma cell contribute little to the ovrall survival of the seed.

콩의 비닐피복 재배시에 최적적심 방법을 구명하고자 본 시험에서 적심방법별 주요 특성 및 수량 비교한 결과는 다음과 같다. 1. R5 stage의 건물중은 두 품종 모두에서 V8 stage의 순적심과 개화시 적심에서 많았는데 이들 처리는 대원콩에서는 무처리 보다 가벼웠고 신부석태에서는 무처리 보다 무거웠다. 그리고 이들 처리는 최적엽면적 지수을 확보하였다. 2. 포장도복은 V8 stage의 순적심에서는 발생하지 않았고 개화시 적심에서는 2~5 정도의 도복이 발생하였다. 3. 개화기는 품종별 처리간 모두 같았고, 성숙기는 대원콩에서 1~2일의 차이를 보였지만 신부석태는 차이가 없었다 4. 종실비대기간인 R5 stage에서 R7 stage까지의 두 품종 평균 순동화량(NAR)은 V8 stage의 순적심과 개화시 적심에서 비슷하면서 가장 높았다. 5. 두 품종 평균수량은 V8 stage의 순적심과 개화시 적심에서 가장 높았다. 6. 외관적 품질에서는 V8 stage의 순적심에서 백립중이 가장 무거웠고 미숙립 및 다른 피해립율도 낮았다. This experiment was carried out to make clear optimum decapitation method for yield increase of soybean and to reduce lodging as soybean is cultivated in vinyl mulching. Results are as follow; In R5 stage, dry matter weight in two varieties was higher in V8 (terminal) treatment and flowering initiation stage treatment which were lighter than control in Daewon and heavier in Sinbuseoktae. Also, LAI(Leaf Area Index) in these two treatments was suitable. Lodging index in V8 (terminal) treatment was not occurred whereas in flowering initiation stage treatment was ranged from 2 to 5. Flowering date in two varieties was not differant among five treatments and maturity date was similar. NAR (Net Assimilation Rate) from R5 to R7 stage was higher in both V8 (terminal) and flowering initiation stage treatment showing similar mean value. Although mean values was not significantly different, the yield of terminal decapitation in V8 stage which was similar to flowering initiation stage treatment was higher. Also, 100-seed weight of terminal decapitation in V8 stage was the heaviest and apparent seed quality was favorable. Consequently, the optimum decapitation method in vinyl mulching cultivation of soybean was terminal decapitation in V8 stage.
