scholarly journals Cultivation of grapes in the conditions of forest-steppe zone of Kharkiv region: modern status and prospects

The purpose of this article is to highlight the possibilities of successful grape growing based on the use of agro-climatic resources of the Eastern forest-steppe of Ukraine, in particular, the relevant areas of Kharkiv region. Main material. Attention is drawn to the needs to intensify research and practical activities on the cultivation of grapes in the region. In the agricultural sector of Ukraine interest in cultivating grapes is growing in more in northern areas, than in its traditional distribution area. An urgent task is a more thorough study of agro-climatic conditions, clarifi cation of agro-clima tic zoning of this culture and the development of practical recommendations. This is especially true of the Eastern forest-steppe of Ukraine and its individual areas, including the northern part of Kharkiv region. This industry, judging by the success of farms and individual economies, can be highly profi table throughout the region but with some reservations. Currently, one of the problems of viticulture is to obtain suffi cient yield to supply the population. For this purpose, the author identifi es the features of the natural conditions of the region. Clarifi cation of agro-climatic features of the territory can be considered as a multi-stage task of agro-climatic zoning at diff erent levels. The Eastern forest-steppe region should be considered as part of a large agroecosystem, occupying a signifi cant place in the forest-steppe zone of Ukraine. Of particular interest are the climatic indicators, the assessment of which allows to justify the grape culture management. These indicators are grouped together. The most important of them are temperature, humidity, light conditions and features of the winter period. Distribution of rainfall (fl ow of water) in the phases of grapes development during the active growing season is also important. It is also necessary to pay a???? ention to the use of other indicators. Most of them are closely related to the hydrothermal coeffi cient (HTC) - the simplest and most informative indicator. It should be added that using special agricultural techniques cultivation of certain grape varieties can be possible in the north-east of Ukraine. Conclusions. The study of suitable forest-steppe agrometeorological regions in Kharkiv region for growing grapes in natural conditions continues to be relevant. This difficult task requires a lot of effort and involvement of specialists.

According to statistic evaluation of the manifestation of signs of the economic suitability of state sort resources of 2019 registration potatoes when growing it in different agro-climatic conditions, a significant advantage of influence of the forest-steppe conditions was determined. Compared to Polesia the increase of yield rose for 4.1 t/ha or 18 % (НІР05 = 2.18, Ffact= 12.65 > F05 = 4.22) and the amount of trade potato for 22.72 ha or 20 % (Ffact = 58.87). There is also a tendency to increase the number of starch from unit of area for – 17 % and the total consumer properties for – 8 %.  However, there is a significant difference in the reduction of storability of products by 45 % and the lack of it’s resistance to macrosporiosis and late blight. It was proved that the yield of varieties for cultivation in the polesia zone by 25.7 % depended on the duration of the growing season (Ffact = 4.14 > F05  = 0.06). The relationship between yield and starch of potatoes in Polesia zone varieties  was determined – 23.6 % and in forest-steppe – 17.3 % and starch collection, respectively, 33.6 % and 28.0 %. The dependence of storability of potato which grew in the polesia zone and in forest-steppe from the amount of starch for 15 % was mathematically proved (Ffact = 2.11 > F05 = 0.17) і 11.3 % (Ffact = 1.52 > F05 = 0.24); the dependence of storability on the duration of the growing season in the Forest-Steppe conditions was confirmed(Ffact = 0.66 > F05  = 0.43). In addition, the 12 % of tasting grade of the Forest-Steppe varieties depended on the starch content amount (Ffact = 1.65 > F05 = 0.22). According to the results of the regression analysis, mathematical models have been developed to predict yields, culinary and consumer properties, and the storability of new potato varieties under different growing conditions. The project of a conveyor for the consumption of fresh product in summer  period with the involvement of varieties of early ripeness in the Forest-Steppe was presented: 80 days after planting – Sanibel, 90 days after planting – Medison, Paroli, 95 days after planting – Bazalia, Bernina, 100 days after planting – Donata, in the Polesia zone ‒ 80 days after planting – Sanibel, 90 days after planting – Paroli, 95 days after planting –Bazalia, 100 days after planting – Medison, Bernina, Donata. By distribution of varieties by predicted high content of phytonutrients there were bred varieties with red skin and creamy flesh – Bazalia and Sanibel, by high content with yellow flesh – Baltic Rosa and moderate content with white flesh – Oleksandrit, Fotynia, Ricarda. Introduction of new varieties with certain high adaptive potential of storability and content of bioactive compounds in potatoes will provide growth of potato production in the conditions of the northeast forest-steppe and increase its competitiveness in the domestic and foreign markets and will solve the problem of year-round consumption of fresh quality products.

The paper publishes new materials of the early Sarmatian time from the North-East periphery of the Sarmatian World – the Southern forest-steppe and steppe zones of the Trans-Ural region within the bounds of the modern Chelyabinsk region. The territory of the Southern forest-steppe is represented by the materials of the ruined burial, which is situated on the shore of the lake Smolino within the bounds of Chelyabinsk. It is dated by the early 4th century BC. There are three accidental finds from this region: iron daggers as well. The daggers with curved bar-shaped pommels and arcuate cross-guards are classified as daggers of “transitional type” and are dated by the 4th century BC. The third dagger with a semicircular pommel and a straight cross-guard is included in the group of classical Prokhorovka daggers and is dated the 3rd – 2nd centuries BC. This paper presents the materials of two peculiar burial complexes from the steppe zone of the Southern Trans-Urals. The burial near Mogutovka village is the only one burial (without a barrow) of the early Sarmatian time, which was investigated in the Southern Trans-Ural region. It is situated on the first terrace above the floodplain of the Kamysty-Ayat river. The localization of the burial is not typical for the sites of the early Trans-Ural nomads of the 1st millennium BC. The early Sarmatian burial of the 3rd – 2nd centuries BC was excavated in Druzhinskiy burial site. It was made in the burial pit, which combines signs of a catacomb and an alcove. A child buried here was dressed in a shirt, whose collar and sleeves were decorated with beading. Publishing materials will help to expand the point of view on burial rites and material culture of the early Trans-Ural nomads of the early Sarmatian time, which exists in scientific literature.

Increasing production and improving the quality of garlic products is an important production problem. Under the conditions of the vertical zonality of the North Caucasus with varying agroecological conditions, the yield of this crop largely depends on the technology of cultivation and the level of its intensity. Important factors determining the yield and quality of garlic products are varieties adapted to these agro-climatic conditions, quality planting material, cultivation technology that meets the requirements of the crop and the agro-climatic conditions of the region. Currently, the potential productivity of the varieties used in the republic is realized only by 30-40 percent. This is due to the insufficient development of technologies for their cultivation, taking into account the specific environmental conditions of the region. In this regard, research aimed at studying the basic laws of the formation of yield and product quality varieties of garlic is a pressing issue.

AbstractThe aim of the study was to determine the distribution of prevailing forest types within the catchment areas of the biggest rivers in the north-east of Ukraine. During the allocation of the catchment areas of the studied rivers, the MapInfo Professional 12.5 program and the vector map of Ukraine were used. The research covered the forest area (more than 502,000 ha) of the state forest enterprises managed by the State Forest Resources Agency of Ukraine. The studied area located on the tributaries of the Sula, Psel, Vorskla and Siversky Donets rivers within the Poltava, Kharkiv, Sumy, Chernihiv, Kyiv and Cherkasy administrative regions of Ukraine. The analysis of the forest fund was carried out based on the electronic subcompartment database of the Ukrderzhlisproekt Production Association, using the application software and geoinformation technologies. It was revealed that a large variety of forest types in the tributaries of the Sula, Psel, Vorskla and Siversky Donets rivers as well as the prevalence of fresh fertile maple-lime oak and fresh fairly infertile oak-pine forest types (in 75 tributaries of Psel, Vorskla and Siversky Donets rivers) and fresh fertile maple-lime oak and fresh fertile hornbeam oak forest types (in 20 tributaries of the Sula River) are due to the relief, hydrological and soil-climatic conditions of the studied area, as well as anthropogenic factor. Assuming homogeneous natural conditions, an insignificant number of forest types are formed (up to five). For a large variety of natural conditions, there are at least six forest types that should be taken into account during forest management, along with the characteristics of the catchment areas of tributaries. The analysed data on the total number of forest types in the catchments of rivers would be appropriate to use in the future when creating a single list of forest types for the Left-Bank Forest-Steppe zone of Ukraine. The prevalence of certain forest types within the catchment areas of tributaries of the Sula, Psel, Vorskla and Siversky Donets rivers directly depends on the soil and climatic conditions, geomorphological structure, relief and anthropogenic influence in the forests. The results should be used in forest management activities to preserve and restore the species diversity of forests within the river catchments.

Potatoes are a valuable product and are of great national economic importance. In terms of the amount of nutrients per unit area, potatoes occupy one of the first places among plants cultivated by humans. In the North Caucasus, the production of marketable potatoes is almost entirely concentrated on the farms of the foothill and mountainous regions, which have favorable natural conditions (sufficient rainfall and moderate temperatures). The solution of almost all problems of the functioning of the agroindustrial complex is focused on ensuring food security. In solving food security in the country and in individual regions, a large role belongs to the development of such an important branch of agro-industrial production as potato growing. The development of this most important industry in the Republic of North Ossetia-Alania is possible only on the basis of innovative modernization of potato growing. In the North Caucasus, the production of marketable potatoes is almost entirely concentrated on the farms of the foothill and mountainous regions, which have favorable natural conditions (sufficient rainfall and moderate temperatures). The area of potato planting in the region reached 35-40 thousand hectares, and at present in the Republic of North Ossetia-Alania there are about 1.5-2.0 thousand hectares under this crop. The aim of the research is to study the characteristics of growth, plant development, heat-drought resistance of various varieties of potatoes in the forest-steppe zone of North OssetiaAlania. As a result of three-year research (2018- 2020), it was found that under the conditions of the forest-steppe zone of North Ossetia - Alania, such early-maturing varieties as - Udacha, VR808, Gulliver, Riviera form up to 29.8 to 33.4 t / ha of early harvest potato tubers and are the most adapted varieties to local soil and climatic conditions.

Echinococcus granulosus (Batsch, 1786) has a worldwide distribution. Different types of carnivores (dogs, jackals, wolves, foxes), domestic and wild ungulates are included in its life cycle. There are significant differences in its pattern of contamination of domestic ungulates in the various regions of Ukraine. Pigs are major intermediate hosts of E. granulosus in the northern and western regions of the country, sheep and cattle in the southern and eastern regions. These differences are associated with strains of Echinococcus. The article presents the results of research conducted on 1,884 pigs, 1,025 sheep and 1,406 cattle in Polesia and the forest-steppe zone of the north-east of Ukraine. We have established the development of Echinococcus larvae in pigs (extent of invasion 10.2 ± 0.6%) and sheep (extent of invasion 0.7 ± 0.2%). The cysts did not develop in cattle. Pigs generally had a low invasion intensity (less than 6 larvae). A high level of invasion intensity (more than 10 larvae) was infrequently recorded in these animals. All sheep had a low level of invasion intensity.The E. granulosus larvae found in sheep were dead. In pigs, most cysts developed to fertile state (139 cases). Young, sterile and dead larvae were less common (39, 10, 4 cases). Pigs older than 10 months had the highest number of fertile cysts. Young larvae dominated in pigs younger than 10 months. In these animals, larvae were localized predominantly in the liver. The kidneys and lungs were infected less frequently. The large number of fertile cysts in pigs older than 10 months made this group of animals the main intermediate hosts of E. granulosus in the north-eastern part of Ukraine. They enable the parasite to function actively here. Analysis of infestation by E. granulosus larvae of domestic ungulates of the Polesia and the forest-steppe zone showed no significant differences. Identified differences were not statistically confirmed.

Вертикальное озеленение с участием различных видов лиан в современных условиях имеет важное эстетическое и санитарно-гигиеническое значение. Особо актуально решение вопросов обогащения флоры городских территорий лианами в степных районах в связи с бедным видовым составом и резким ухудшением экологической ситуации. Объектами исследований являлись 7 видов лиан, различных жизненных форм (однолетние, многолетние), произрастающие в населенных пунктах Саратовской области (Аткарск, Саратов). Цель исследований – изучение эколого-биологических особенностей и мелиоративных свойств лиан и выявление перспектив их использования в вертикальном озеленении селитебных территорий Саратовской области. В ходе исследования видового состава, были выявлены наиболее популярные виды однолетних лиан: ипомея красно-голубая (Ipomea tricolor (L.) Roth) и ипомея пурпурная (Ipomea purpurea (L.) Roth), горошек душистый (Lathyrus edoratus L.), настурция (Tropacolum peregrinum L.) и фасоль огненно-красная (Phaseolus coccineus). Большинство (70%) из них произрастают в местах ограниченного пользования. Изученные виды лиан в исследуемых регионах достигают средних природных показателей (при наличии надлежащего ухода), обладают хорошими показателями жизненного состояния, обильно цветут и плодоносят. При воздействии токсикантами различной концентрации на листовые пластинки лиан установлено их степень устойчивости. Выявлено, что однолетние лианы лучше использовать в декоративных целях, а не в санитарно-гигиенических. Сравнительная оценка однолетних видов с многолетними лианами (девичий виноград пятилисточковый и клематис тангутский) показывает устойчивость многолетних видов (в среднем на 3 балла - 40%). Разработаны варианты декоративных композиций с участием травянистых лиан. По степени декоративности выделены однолетние лианы – Ipomea tricolor, I. purpurea (37 – 41 балл), средней степенью отличаются – Lathyrus edoratus (33 балла), Tropacolum peregrinum (30 баллов) и Phaseolus coccineus (20 – 27 баллов). Преимущество многолетних лиан заключается в их устойчивости к резким изменениям климатических условий (на 40 %) по сравнению с однолетними формами. Поэтому они более предпочтительны для озеленения городской среды. Для усиления декоративного эффекта в сезонном аспекте рекомендуются сочетать расширение видового и формового разнообразия растений (многолетние и однолетние лианы, древесно-кустарниковая, цветочная растительность). Установлено, что природно-климатические условия зоны степи и лесостепи в пределах Саратовской области являются достаточно благоприятными для нормального роста и развития древесно-кустарниковой растительности, в том числе травянистых лиан. Таким образом, обоснованное применение древесных лиан в комплексе с традиционными видами насаждений позволит создать комфортные условия проживания населения, регулировать оптимальный температурный баланс и создавать благоприятные микроклиматические условия. Vertical gardening with different types of vines in modern conditions is important aesthetic and sanitary-hygienic value. It is especially important to address the issues of enrichment of the flora of urban areas with vines in the steppe regions due to poor species composition and a sharp deterioration of the ecological situation. The objects of research were 7 species of lianas, various life forms (annual, perennial), growing in the settlements of the Saratov region (Atkarsk, Saratov). The aim of the research is to study the ecological and biological features and reclamation properties of vines and identify the prospects for their use in vertical gardening residential areas of the Saratov region. In the study, species composition was the most popular species of annual vines: morning glory red-blue (Ipomea tricolor (L.) Roth) and purple morning glory (Ipomea purpurea (L.) Roth), the fragrant pea (Lathyrus edoratus L.), nasturtium (Tropacolum peregrinum L.) and runner beans (Phaseolus coccineus). Most (70%) of them grow in restricted areas. Studied species of vines in the study regions reach average natural performance (with proper care), have good indicators of vital condition, bloom abundantly and bear fruit. When exposed to toxicants of different concentrations on the leaf blades of vines established their degree of stability. It was revealed that the annual vines are better used for decorative purposes, and not in the sanitary-hygienic. A comparative assessment of annual species with perennial vines (maiden grapes and clematis Tangut) shows the stability of perennial species (an average of 3 points-40%). The options and decorative compositions with the participation of herbaceous vines. According to the degree of decoration of the allocated annual vine – Ipomea tricolor, I. purpurea (37 – 41 points), the average degree of differ – Lathyrus edoratus (33 points), Tropacolum peregrinum (30 points) and Phaseolus coccineus (20 to 27 points). The advantage of perennial vines is their resistance to sudden changes in climatic conditions (40 %) compared to annual forms. Therefore, they are more preferable for greening the urban environment. To enhance the decorative effect in the seasonal aspect, it is recommended to combine the expansion of species and form diversity of plants (perennial and annual lianas, tree and shrub, floral vegetation). It is established that the climatic conditions of the steppe and forest-steppe zone within the Saratov region are quite favorable for the normal growth and development of tree and shrub vegetation, including herbaceous lianas. Thus, the reasonable use of wood vines in combination with traditional types of plantings will create comfortable living conditions for the population, regulate the optimal temperature balance and create favorable microclimatic conditions.

A growth in the number of deer and an increase in their productivity are closely related to the solution of the complex problem of reproduction and rational use of deer females. Significant damage to reindeer husbandry is caused by the barrenness of northern domestic deer, the level of which has been quite high in recent years. So, in the Republic of Sakha, on 01.01.2020, the number of domesticated reindeer was 152,068, of which female deer and heifers — 71,818, offspring per 100 females — 59, business yield amounted to 52 fawns per 100 females. The causes of infertility are very diverse, as the natural and climatic conditions of the breeding zones have a significant influence on the reproductive function of reindeer. In Yakutia, the main population of northern domestic deer is bred in mountain taiga and tundra natural-climatic zones, so there are about 55 thousand deer in the mountain taiga zone and more than 65 thousand deer in the tundra zone. In this regard, the study of the peculiarities of the postpartum period course in domestic reindeer females, its morphophysiology, and behavioral reactions depending on the natural and climatic conditions of breeding is of great importance.
