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.
