The results of research into rice sown for grain (2017–2018) are presented. The effectiveness of Concord fungicide (active ingredients tebuconazole, 125 g/l; triadimefon, 100 g/l) against rice Pyricularia was studied. The experiment was conducted in the conditions of the greenhouse experiment in the Primorsky Territory. Artificial inoculation of plants was carried out in the phase of 4–5 leaves with a suspension of conidia of the fungus Pyricularia oryzae Broomeet Cavara (concentration of 100 thousand in 1 ml). The test results were compared with the action of the preparation Favorit (active ingredients tebuconazole, 125 g/l; triadimefon, 100 g/l). Concord fungicide was used once on the next day after inoculation at a normal rate of 0.75; 1.0 and 1.25 l/ha. Under the influence of the preparation, the damage to rice plants decreased by 57.5% (0.75 l/ ha); 70.0 (1.0) and 69.5% (1.25 l/ ha) compared to the control. The use of fungicide contributed to an increase in plant growth by 7.6– 13.3 cm, and panicle length by 1.4–2.9 cm, and had a positive effect on the number of grains and the weight of grains in an ear. With the action of Concord, the mass of 1000 grains increased by 1.38 (0.75 l/ha); 2.14 (1.0) and 3.03 g (1.25 l/ha) compared to the control. The positive effect of fungicidal treatments of rice crops led to obtaining an additional grain yield. Concord does not show a phytotoxic effect and does not have a retardant effect on rice plants. The maximum indicators of biological efficiency were obtained with the use of the preparation at a flow rate of 1.0 and 1.25 l/ha. In agro-climatic conditions of the south of the Far East, Concord fungicide proved to be effective for protecting rice vegetating plants from Pyricularia.

Introduction. The article considers the features of traditional clothes of descendants of Belarusian peasant migrants of the second half of the 19th and early 20th centuries living in Siberia and the Far East. Methods and materials. Basic materials of the study is oral descriptions of clothing, which were collected among descendants of migrants, who were born in the 1910s – 1950s, and also visual observation of the samples of traditional clothing which are stored in museums. On the basis of using the comparative-historical and typological methods, the transformations of the practice of making and wearing clothing have been investigated. Analysis. The analysis of the field materials indicates that the traditional clothing of Belarusian migrants continued to play an important role in their domestic culture from the late 19th century to the 1950s – 1960s. The traditional complex of Belarusian clothing has undergone transformations in a new place because of needs to adapt it to the different natural and climatic conditions, by borrowing from the new ethnic environment, as well as general processes of modernization of the way of life. Due to colder climate of the Asian part of Russia, transformations of winter outerwear and shoes were the most dynamic. Results. The features of ethno-cultural identity had an influence on the degree of preservation of the original complex of clothing of the Belarusians. Traditional types of clothing from the places of exit were most preserved in the places of homogenous residence of Belarusian migrants. In cases of dispersed residence with a high proportion of mixed marriages, the Belarusians faster adopted prototypes of clothing that were typical of their new ethnic environment.

The Development Trend

<p>Soybean production is the main branch of specialization of agriculture in the south of the Far East, which is due to the unique natural advantages associated with favorable climatic conditions for the cultivation of this crop. In Russia, soybean as an agricultural crop has not historically found wide distribution, which is due to the exacting nature of this plant for various factors of production, the undeveloped culture of consumption of soy products in the diet of the population. Therefore soybeans were more used as technical raw materials for the production of the most important products of its processing - oil and meal. The purpose of this study is to identify trends in the soybean seeds market in the Far East and develop recommendations for improving the efficiency of its functioning in modern conditions. The methodology of soybean market research is based on the synthesis of economic analysis and applied methods developed in mathematical statistics. The scientific value of the results of the study is to identify the development trend of the soybean market localized in the Far East of Russia and to develop practical recommendations that complement the main provisions of the theory of spatial development and institutional configuration of market structures in the agrarian sphere.</p>

Вопросы интродукции особенно актуальны в агроценозах Среднего Приамурья, так как расширение биологического разнообразия генофонда зерновых колосовых культур позволит наиболее эффективно использовать природные ресурсы региона и обеспечить продовольственную безопасность населения. Одним из путей увеличения производства высококачественного продовольственного и кормового зерна является использование потенциала зерновой культуры – ярового тритикале. Благодаря специфическому геному, включающему компоненты пшеницы и ржи, тритикале обладает высокими потенциальными возможностями повышения продуктивности и является перспективным в условиях дефицита средств интенсификации сельскохозяйственного производства. В статье приведены результаты исследований по яровому тритикале за 2015–2019 гг. На опытных полях Дальневосточного НИИСХ проведено комплексное экологическое изучение коллекционных сортообразцов ярового тритикале. Выделены эффективные источники и доноры по важнейшим хозяйственно ценным признакам, отмечены особенности формирования урожайности ярового тритикале в зависимости от гидротермического режима вегетации, установлена реакция сортообразцов на изменение условий окружающей среды. Создан новый гибридный и селекционный материал ярового тритикале с комплексом хозяйственно ценных признаков и адаптивных свойств для почвенно-климатических условий Дальнего Востока. Показана перспективность использования этого уникального растения в сельском хозяйстве и различных областях промышленности. Introduction issues are especially relevant for the agrocenoses of the Middle Amur Region, because the expansion of the biological diversity of the cereal crops gene pool allows the most efficient use of the region’s natural resources, and ensure food safety for the population. One way to increase the production of high-quality food and fodder grain is to use the potential of spring triticale. Due to the specific genome, which includes wheat and rye components, triticale has a high potential in increasing productivity, and is promising in the face of the lack of agricultural production intensification means. The article presents the results of studies on spring triticale for 2015–2019. A comprehensive ecological study of the spring triticale cultivar collection was conducted on the experimental fields of the Far Eastern Agricultural Research Institute. Effective sources and donors of the most important economically valuable traits were identified, the dependence of the formation of spring triticale yield from the hydrothermal regime of the growing season was established, and the reaction of cultivar samples to the changing environmental conditions was determined. A new hybrid and a breeding material of spring triticale with a complex of economically valuable traits and adaptive properties to the soil and climatic conditions of the Far East was created. The prospects of using this unique crop in agriculture and various industries were shown.

When operating long railway tunnels in harsh climatic conditions of Siberia and the Far East, there is a problem of tunnel lining freezing on near-entrance sites in the cold season. Due to the cyclical effects of negative outside temperatures, the surface layer of tunnel lining is constantly freezing and thawing, which causes rapid frost deterioration. This effect is especially pronounced for tunnels with closing near-entrance gates and one-way train traffic on the exit site. This is explained by the fact that at each train passage through the exit site, a significant amount of cold atmospheric air enters the tunnel. The length of chilling zone and the temperature of tunnel lining in the “outside air - tunnel lining” contact zone from the exit site deep into the tunnel, depending on the technological and climatic parameters of the tunnel are justified by analyzing the results of computational experiment. The correctness of obtained regularities is justified by the convergence of experimental results and analytical calculations based on the displacement method.

Background: Horseradish is a valuable agricultural crop with gastronomic and medical significance. It contains mono- and polysaccharides, protein compounds and organic acids, minerals and starch, as well as a rich vitamin complex. Unfortunately, horseradish diseases are still insufficiently studied, while crop losses from them can be quite significant. The purpose of our study was to determine the composition of pathogenic fungi on horseradish Armoracia rusticana G. Gaertn., B.Mey. and Scherb. and to develop measures to combat them. Methods: The research was carried out on horseradish “Atlant” varieties in the plantings of the of FSBSI “Far East Federal Research Center of agrobiotechnology n.a. A.K. Chaika” at 2019-2020. Studies of phytopathogens were carried out in the field conditions and in vitro. Microscopy was performed using Levenhuk D740T, 5,1 MP. Lifelong injuries photofixation was performed using Sony SAL1855. Processing of the microscopy results was carried out using Outfi, PluriIQ, CellProfiler software. In the experiment to study the agent fungicidal efficacy against horseradish diseases, we used: Acrobat WG, Bravo SC, Zummer SC, Consento SC, Infinito SC, Topaz EW, Ordan SP, Thiovit Jet WG, Rajok EW, Proton Extra RG, Ridomil Gold MZ RG. The agents were diluted in doses of 10%, 30% and 70% of the recommended dose, the index of conidia occurrence was calculated, phytotoxicity was carried out. Result: For five iterations, the greatest fungicidal activity was demonstrated by the Acrobat WG, Topaz EW and Proton Extra WG agents. The maximum effectiveness was observed for the agent Ridomil Gold MZ WG. The lowest efficiency was shown by the Infinito SC, Consento SC, Ordan SP, Thiovit Jet WG agents. No phytotoxic effect was found in any of the agents.

In this article on the basis of documentary evidence and memories of the participants of the events shows, what was the sentiments in the summer of 1945, after the victory over Germany, when the Soviet troops departed from Europe to the far East, to participate in the war with Japan, and how the Soviet command solved a difficult problem - to mobilize for perform the new military tasks people who were weary up to the limit from years of war, dreamed of a speedy return to their families and relatives on. Also review the features of the preparation for a new war veterans of European fights and “dalnevostochny stays”, with the consideration of rich combat experience of the first category of servicemen and better knowledge of the natural-climatic conditions of the forthcoming theatre of war the second category. In article analyzes massive army representation of the Japanese as a military rival and their correspondence to reality. Underestimation of the enemy in the first days of the war led to a “criminal carelessness” and losses, so the commanders had to strengthen explanatory work with staff about insidiousness of the enemy and vigilance increase. The bitterness of the fighting shows in widespread phenomenon of “kamikaze bombers. Special attention is paid to violations of the Japanese party norms of international law, the laws and customs of war. In conclusion it is shown that the military campaign of the Soviet army in the far East not only hasten the end of the Second world war and provided a new balance of strategic forces in the postwar world, but also contributed to the eventual eradication of complex of a defeated country, inherited from tsarist Russia.
