The paper presents the results of the study of collection samples of awnless bromegrass from the Federal Research Center N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) to identify donors of valuable breeding traits. The study was carried in 2015-2018 in Tomsk region. The soils of the experimental plots were sod-podzolic, sandy loam by granulometric composition, with a humus content in the arable layer of no more than 2%. The recorded area of the plot was 0.5 m2. The trials were repeated two times. Procedures for trial establishment, phenological observations, harvest recording and data processing were performed in accordance with the methodological recommendations of the All-Russian Williams Fodder Research Institute, VIR and the State Variety Testing Methodology. The years of the study were characterized by uneven distribution of heat and moisture during the growing season. This made it possible to identify the most adaptive samples for selective breeding of awnless bromegrass which can be used as a hay and pasture plant in the taiga zone. The following valuable source materials were selected for tall varieties: Khabarovsky, Titan, Vozvyshensky, SibNIISkhoz 88; samples of wild plants Yakutia (K-14215), Vologda (K-14224), Omsk (K-14228), Sverdlovsk (K-14209) regions, a local sample of Tomsk region (K-14226).

The results of studying the elements of the technology of cultivation of a new variety of winter rye Sudarushka are presented. The research took place in 2019, 2020 in the sub-taiga zone of the Tomsk region. The impact of soil cultivation methods as well as the impact of humic fertiliser from peat Gumostim on the yield of winter rye Sudarushka is evaluated. The soils of the experimental plot are acidic (pH 4.3) soddy-podzolic loamy sandy loam. The arable horizon has a low humus content (1.5%), a low (0.2 mg/100g) content of nitrate nitrogen, a medium content of mobile phosphorus (19.2) and exchangeable potassium (7.1) and a high (11.0 mg/100g) content of mobile aluminium. The scheme of the experiment included four variants of cultivation: ploughing of fallow lands with PlN-4-35 + cultivation KPN-4,2, sowing without packing and with packing; disking with BDMK-2,8 + cultivation KPN-4,2, sowing without packing and with packing. Treatment with humic fertilizer from peat Gumostim at a concentration of 0.001% was carried out during the growing season in the beginning phase of the leaf-tube formation. The average yield of winter rye in the variety Sudarushka during the years of research was 4.66 t/ha in the variant with disking, subsequent cultivation before sowing and further sowing with packing, which is 0.34 t/ha higher than with the traditional method of soil cultivation. The application of humic fertilizer from peat Gumostim on cold sod-podzolic soils enabled the average yield of winter rye to be 4.31 t/ha y, which is 0.39 t/ha higher than without the fertilizer.

One reliable way to restore eroded soils and technogenic land is to reclaim it by sowing perennial grasses. Samples of reed canary grass suitable for reclamation of coal dumps in the Kemerovo region have been studied and identified. Experimental work was carried out in the Tomsk region (5811 N, 8300 E) during the period of 2017-2020. The research subjects are represented by samples of reed canary grass taken in 2016. A nursery of study samples suitable for reclamation of coal dumps was laid in 2017 with six numbers - KM-1, KM-2, KM-3, KM-4, KM-5 (Tomsk region), the variety Vityaz (Tomsk region) was used as a standard. The soils of the experimental plots were sod-podzolic acidic loamy sandy loam and loamy with a humus content of no more than 2% in the arable horizon. When evaluating the samples, the main attention is paid to studying the traits and properties that limit their cultivation under taiga conditions: grass density, plant height, foliage, winter hardiness, lodging resistance, seed productivity, green mass yield, resistance to the most common diseases. Over a 3-year study of selections of reed canary grass based on a set of the main economically important traits, the KM-5 sample has been identified. This specimen has a complex of valuable features in creating an adaptive variety suitable for reclamation of coal dumps (foliage - 61.4%, green matter yield - 38.5 t/ha, dry matter - 11.9, seeds - 0.21 t/ha). The selected number has annual reliable additions to the standard in terms of green matter yield of 8.5 t/ha, dry matter yield of 3.3, and seed yield of 0.04 t/ha. Samples KM-1, KM-5 showed high resistance to these diseases: helminthosporiosis - 6.0-6.1%, septoriosis - 2.6-4.2%.

Цель исследования усовершенствование способа обогащения растений чеснока селеном до уровня суточной нормы потребления путем обработки вегетирующих растений растворами селенитов натрия и калия в сочетании с поверхностно-активными веществами и диметилсульфоксидом. Исследования проведены во ВНИИО филиале ФГБНУ ФНЦО, в условиях открытого грунта в 20162018 годах, на супесчаной почве, содержание гумуса в которой составляло 3,413,44, рНKCl 6,7, степень обеспеченности питательными веществами: фосфором высокая (содержание P2O5 в слое 020 см составляло 22,7824,62 мг (по Чирикову) калием низкая, содержание К2О в слое 20 см 10,3817,88 мг (по Масловой). Для улучшения минерального питания растений осенью под основную обработку в почву вносили калий хлористый в дозе 50 г/м2, в период вегетации проводили подкормки растений: первую, в фазе начала интенсивного роста листьев аммиачной селитрой 30 г/м2, вторую, через две недели после первой сульфатом калия 50 г/м2. Погодные условия в течение периода исследований были благоприятны для выращивания чеснока. Поливы проводили по мере подсыхания верхнего слоя почвы. Исследования проведены на чесноке озимом сорта Гладиатор. Схема опытов предполагала предпосадочное замачивание зубков в течение 30 мин. и последующую двукратную обработку вегетирующих растений 0,1-ным раствором селенита натрия и калия в сочетании с поверхностно активными веществами (1) и диметилсульфоксидом (1): первый раз в фазе начала интенсивного роста листьев и второй через три недели. Установлено, что некорневая обработка растений селенитом натрия была в 2,3 раза, а селенитом калия в 5,8 раза эффективнее, чем корневая. Сделан вывод о том, что луковицы чеснока, полученные, в результате некорневой обработки растений 0,1-ным раствором селенита натрия и калия в сочетании с поверхностно активными веществами и диметилсульфоксидом содержат в 145,3169,8 раза больше селена, чем контроль, что позволяет получить зубки, содержащие селен в концентрации 6,837,98 мг/кг. Суточная норма потребления чеснока составляет примерно 10 г, средняя потребность в селене составляет от 30 до 70 мкг. Учитывая, что содержание селена в обогащенной продукции составит 68,3 79,8 мкг/10 г чеснока предложенный способ обогащения позволяет в полной мере удовлетворить суточную потребность организма человека в этом микроэлементе.The aim of investigation was to improve the method of enrichment of garlic plants with selenium to the level of daily consumption rate by treatment of vegetative plants with solutions of sodium and potassium selenites in combination with surfactants. The investigations were carried out at ARRIVG branch of FSCVG, in open ground in 20162018, on sandy loam soil with humus content of 3.413.44, pHKCl 6.7, content of phosphorus (P2O5) in the layer 020 cm was 22.7824.62 mg (Chirikov) content of potassium (K2O) 10.3817.88 mg (Maslova). To improve mineral nutrition of plants fall under the basic treatment in the soil was added potassium chloride at a dose of 50 g/m2 during the growing season were plant nutrition: first, in the early phase of intensive growth of leaves ammonium nitrate 30 g/m2, the second, two weeks after the first potassium sulphate and 50 g/m2. Weather conditions during the period of growth were favorable for growing garlic. Watering was carried out at the periods where the top layer of soil was dried. Studies were carried out on variety Gladiator of winter garlic. The experimental design included soaking the cloves for 30 minutes before planting, and subsequent double treatment of vegetating plants with 0.1 solution of sodium and potassium selenite in combination with surfactants (1) and dimethyl sulfoxide (1): the first time in the phase of the beginning of intense leaf growth and the second time after 3 weeks. As a result of the investigations it was found that non-root treatment of plants with solutions containing selenium was more effective than root treatment. Non-root top dressing with sodium selenite was in 2.3 times, and potassium selenite in 5.8 times more effective than root. It is concluded that garlic bulbs obtained as a result of non-root treatment of plants with 0.1 solution of sodium and potassium Selenite in combination with surfactants and dimethylsulfoxide contain 145.3169.8 times more selenium than control, which allows to obtain teeth containing selenium in a concentration of 6.837.98 mg/kg. The daily consumption rate of garlic is approximately 10 g, the average need for selenium element is from 30 to 70 micrograms. Because of content of selenium in enriched products consisted of 68.3-79.8 mcg/10 g of garlic, the proposed method of enrichment allows to fully satisfy the daily need of the human body at this microelement.

Simplification of human diets associated with increased accessibility of inexpensive agricultural commodities and erosion of agrobiodiversity leads to nutrient deficiencies and excess energy consumption. Non-communicable diseases are growing causes of death and disability worldwide. Successful food systems in transition effectively draw on locally-available foods, food variety and traditional food cultures. In practice this process involves empirical research, public policy, promotion and applied action in support of multi-sectoral, community-based strategies linking rural producers and urban consumers, subsistence and market economies, and traditional and modern food systems. Implementation of the International Plant Genetic Resources Institute's Global Nutrition Strategy in Sub-Saharan Africa offers a useful case study. Relevant policy platforms, in which biodiversity conservation and nutrition are and should be linked, include the Millennium Development Goals, Millennium Ecosystem Assessment, Convention on Biological Diversity, Global Strategy on Diet, Physical Activity and Health, Food-Based Dietary Guidelines, Right to Adequate Food and UN Human Rights Commission's Permanent Forum on Indigenous Issues. The largely unexplored health benefits of cultivated and wild plants include micronutrient intake and functions related to energy density, glycaemic control, oxidative stress and immuno-stimulation. Research on the properties of neglected and underutilized species and local varieties deserves higher priority. In tests of the hypothesis that biodiversity is essential for dietary diversity and health, quantitative indicators of dietary and biological diversity can be combined with nutrition and health outcomes at the population level. That traditional systems once lost are hard to recreate underlines the imperative for timely documentation, compilation and dissemination of eroding knowledge of biodiversity and the use of food culture for promoting positive behaviours.

Natural products from plants are still important sources for the development of drugs, despite their recent neglect in pharmaceutical discovery programmes. The rapidly dwindling number of species endangers the availability of these natural compounds, which are characterized by the immense chemical and functional diversity ultimately responsible for their pharmaceutical activity. Although many steps in the drug discovery process have been continuously modified during recent years, a common dilemma is still unresolved, i.e. the supply crisis for hits discovered in rare wild plants due to their inaccessibility or lack of reproducibility. New technology, combining tissue culture, functional genomics and metabolomics, shows promise to overcome these problems and even to supply a greater chemical diversity of compounds.

Currently, a significant part of the rural territories of the regions of Russia is characterized by low production potential, a low level of agricultural development. For such territories, tourism could be the driver of socio-economic growth and innovative development in time. It was therefore increasingly important to develop a conceptual approach to rural development based on tourism innovations, which was the aim of the study. To achieve the goal, the following methods were used: conceptual approach to rural development, economic and statistical methods, sociological survey, expert assessment, data capture and other methods of analysis and synthesis. The results of the survey: an analysis of the socio-economic situation of the rural territory was carried out on the example of the rural settlement of Zarechnoye in the Veliko-Ustyug district of the Vologda region, the main problems were identified: demographic and infrastructural, as well as a low level of productive potential. Based on the analysis, a conceptual approach to rural development was proposed through the development of tourism innovations. The conceptual goal is to increase the attractiveness and innovative development of the rural settlement of Zarechnoye based on its natural and cultural and historical potential. The projects proposed within the framework of the approach were aimed at improving and increasing the attractiveness of the territory for internal (local population) and external entities — investors, tourists, to promote the settlement in the external environment as a promising area for life and a favorable place for recreation. The target indicators for the development of rural settlement had been set: an annual increase in the number of residents registered on the territory of the settlement, and the formation of a stable inbound tourist flow. Scientific novelty: the originality of the author’s conceptual approach to the development of rural areas was determined by the possibility of their integrated development through the creation of a coastal tourist and recreational zone, which made it possible to fully realize the cultural, historical and natural potential of rural settlements. Practical significance: the main provisions and conclusions of the article can be used by regional and local authorities and management to develop programs and projects for the development of tourist activities in rural areas. Conclusion: The study suggests that the creation of tourist and recreational areas in rural areas, taking into account the cultural and natural heritage of settlements, will contrib¬ute to the effective realization of their tourism potential and can become an incentive for innovative development of rural areas in modern conditions.

Introduction. Sources of non-centralized water supply are the most important resource of drinking water for the population of rural areas. As a rule, water is taken from small depths, which makes it vulnerable to pollution. This type of water use is characterized by the absence of any preliminary water treatment. The constant use of groundwater for drinking can negatively affect the health of the local population since the indicators of its chemical and microbiological composition are not controlled in any way and do not always meet the quality standards. All this determines the relevance of the research conducted in the territory of the Tomsk District (Tomsk Region). Methods. Groundwater quality was assessed by comparing the concentrations of substances in the studied water samples with the background values established for the given territory in relation to Sanitary Norms and Regulations as well as microbiological indicators. Changes in the chemical and microbiological composition of the studied water, caused by economic activity, were taken as “pollution” as compared to the natural (background) state for this territory as well as sanitary and hygienic standards. Results. According to the results of studying the chemical composition of water, high levels of the following components were observed: total hardness, Na+, K+, SO42–, Cl–, NO3–, Fe, and Mn. As for NO3–, Fe, and Mn, their concentrations exceed manifold not only the background values but also the maximum allowable concentrations for drinking water. Microbiological analysis showed a large number of microorganisms from various physiological groups, which indicates a high degree of bacterial contamination of water. We present possible reasons for the input of pollutants into the water and review briefly the adverse health effects. Conclusion. In order to prevent the possible negative impact of excessive contents of various components in the chemical composition of water on the health of the local population, preliminary water treatment using available methods is recommended.

Abstract The aim of the research is to identify the recreational potential of green plantings in the vicinity of the village of Kradikhino, Kichmengsko-Gorodetsky district of the Vologda Region. The research has been carried out according to the methods of a comprehensive assessment of the recreational potential of S.L. Rysin. The research results indicate that the most recreationally valuable plantings are concentrated in commercial forests. Recreational value plantings of Class III predominate in protective forests (60%), and of Class II – in commercial ones (54%). The expediency of recreational use of these plantings by the local population has been noted. The negative impact on the recreation of clear cuttings in commercial forests has been revealed. Some measures have been recommended to optimize the multifunctional use of the forests. Taking into account the high recreational value of commercial forests, it is advisable to create a landscape reserve in the 1st and 11th compartments of the Karyugsky forestry, where scientific work should also be organized to study the effect of recreation on the forest environment.

We studied the fiber flax varieties bred in the Tomsk region in 2017–2019 in the subtaiga zone of the Omsk region on the experimental field of the Northern Agriculture Department of the Omsk Agricultural Scientific Center. We provide the material for 7 varieties. The soil of the experimental plot is gray wooded podzolic, medium, loamy with a humus content of 3–4 %. The predecessor is spring wheat after fallow. The research results showed that the weather conditions significantly affected the growth, development, and formation of the yield. In 2017, cold and wet weather generally affected the yield and quality of fiber flax in comparison to 2018-2019. As a result of the research, we established that for 3 years the best varieties were TOST 5 and Tomich. The variety TOST 5 gave a straw yield of 4.70 t/ha with number 1.9, an estimated fiber yield of 1.31 t/ha and a seed yield of 0.80 t/ha with the growth season of 61 days. The variety Tomich was characterized by the high quality of straw with number 2.1 with a short growth season (48 days), it had a straw yield of 4.0t/ha, a fiber yield of 1.18 t/ha and a seed yield of 0.70 t/ha. Therefore, the combination of varieties of different ripening duration will optimize the harvesting timing, raise the flax straw, and get a high yield of quality products.
