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.

Purpose. Study of the anatomical and morphological structure of the stem of winter wheat hybrids depending on fertilization backgrounds and seeding rates in agrocenoses of the Right-Bank Forest-Steppe natural zone of Ukraine. Methods. Observation, comparison, analysis and synthesis, forecast, field experiment. Results. The study of the dynamics of formation and functioning of the anatomical and morphological structure of the stem of winter wheat plants was carried out. The influence of the background without fertilizers and against the background of their increased level of application on the length of internodes (1-3) of stems in winter wheat agrocenoses was studied. It has been proven that seeding rates significantly influenced the length of the internodes. The influence of the background of mineral nutrition and seeding rates on the main anatomical and morphological parameters of winter wheat stems, in particular, the thickness of the stem and ring of mechanical tissue, the number and diameter of vascular-fibrous bundles was studied. It was found that the strength of the straw is largely determined by the number of vascular-fibrous bundles, as well as their diameter. It was the biggest on the variants with the increased fertilization background. It is noted that anatomical and morphological studies are needed in order to ensure the development of a more durable straw, which determines high resistance to lodging at a seeding rate of 3 and 1.5 million seeds/ha. Conclusions. On the basis of the conducted studies, it was found that the soil and climatic conditions of the years of the study and the factors that were studied have a direct influence on the anatomical and morphological parameters of wheet. At the same time, the best conditions for the maximum realization of the potential of the Patros hybrid of winter wheat plants were created in the experimental variants with a seeding rate of 3 and 1.5 million seeds/ha, ensuring the development of a more durable straw, which led to a high resistance to lodging.

In terms of geographical distribution and consumption, potatoes occupy one of the leading positions in the structure of food production in Ukraine. It is also used extensively as animal feed. The versatility of use in diff erent sectors of the economy with potatoes cannot be compared to any crop. Potato is of great importance as a raw material for the production of starch, sugar, molasses, alcohol, glucose and etc. A signifi cant reduction in the commodity production of food potatoe in farms is related to the solution a whole complex of important issues, in particular seed production, agro-technology of cultivation, application of highly eff ective pesticides, availability of agricultural machinery and material-technical support. The difficult ecological and energy situation in modern agriculture proves that it is possible to obtain high and stable yields of all crops only if there are varieties in production adapted to diff erent soil and climatic conditions. Variety is one of the important factors of yield stability and fi xed assets of agricultural production. A variety, as a genotype or a set of very close genotypes, exists in a specific environment and, moreover, interacts with it, encountering complex communication, intensity and time of manifestation, abiotic and biotic factors. At the same time, a connection is established between a variety and an environment that infl uences the formation and manifestation of morphological, economic and biological characters. The aim of the research was to study the growth, development and yield of early ripe potato varieties in the rightbank Forest-Steppe of Ukraine. The article presents the results of studies on the cultivation of early ripe varieties of potatoes. Namely, the germination and survival of potato plants was studied, which amounted to 89.5 and 87.3 % in the Skarbnytsa variety, 90.2 and 88.7 % in the Shchedryk variety, and 88.6 and 86.5 % in the Dnipryanka variety; the number of formed stems per plant is calculated, which is 3.3 in the Skarbnytsa variety, 3.6 in the Shchedryk variety and 2.7 in the Dniprianka variety. The dynamics of the mass increase and the fractional composition of potato tubers are shown. On average, during the research, the average weight of tubers from the bush was high for the Shchedryk variety and amounted to 616.2 g, somewhat less than those for the Skarbnytsa (484,5 g) and Dniprianka (397,8 g) varieties. It was established that the Shchedryk variety had the highest potato productivity in the experiment – 250.3 c/ha, in the Skarbnytsa and Dnipryanka varieties, the yield was 210.0 and 201.2 c/ha, respectively.

The article presents the effectiveness of the influence of certain agrotechnical components of the technology of growing wheat wheat in the conditions of the Right Bank Forest-steppe of Ukraine. The positive influence of application of foliar fertilization of crops is shown. The prospects of using the complex application of intensification elements are determined. It has been established that the optimization of the mode of power provides a more complete disclosure of the resource potential of plants, which increases yields. Reindeer nutrition should be considered as an element of supplementation to the soil nutrition system, primarily due to the fact that plants are able to absorb nutrients through the leaf surface only in limited quantities, with excess concentration of which possible burns or intoxication of plants. The use of foliar feeding on the background of the main fertilizer has been found to have a positive effect on productivity and quality. The role of the plant nutrition system, which allows to control the formation of grain productivity of spring wheat crops, is substantiated. It has been found that the optimization of the nutrition regime provides a fuller disclosure of the resource potential of the plants, thereby increasing the yield. Nutrition optimization provides more complete disclosure of plant resource potential, thereby increasing yields. It is determined that under the conditions of the Forest-Steppe of Ukraine the level of spring wheat yield is largely determined by the amount of rainfall that has fallen during the growing season. By optimizing the wheat's nutritional conditions, its productivity increases substantially, regardless of weather and climatic conditions. The use of mineral fertilizers, especially nitrogen in combination with phosphorus and potassium, can significantly improve the nutritional regime of the soil. The available nutrients of the plant are provided as a result of the mineralization of organic compounds by soil microorganisms and the transition of soluble mineral substances into solubility. This creates a more favorable environment for the growth and development of plants and for maintaining high soil fertility. At the end of the spring wheat vegetation, there was a redistribution of nitric and ammoniacal forms of nitrogen. It is advisable to continue research in this area and to deepen in connection with the emergence of new varieties, preparations and changes in climatic and soil conditions.

Due to the intensification of production of parsnip, the question arises to clarify the elements of cultivation technology that should ensure its high productivity. The use of varietal plant resources is one of the most important parts of agriculture - the basis of economic and social development of the state. The most efficient and cost-effective is the widespread introduction of new varieties and hybrids with a genetically determined level of adaptation to the conditions of soil and climatic zones of their cultivation. The indicator of the dynamics of the formation of photosynthetic productivity is the basis of the yield of each crop. The purpose of the research was to study the dynamics of leaf surface formation in varieties of parsnip in the conditions of the Right-Bank Forest-Steppe of Ukraine. The studied cultivars of parsnip sowing formed a high area of active assimilation surface, the dynamics of which depends on the stage of organogenesis, soil and climatic conditions of the year and varietal characteristics. With the highest average for the growing season leaf area (49.0-49.6 thousand m2 on ha), photosynthetic potential (1.79-1.83 million m2 per day on ha) and net productivity of photosynthesis - 5.56 g on m2 per day) were characterized by varieties Stymul and Pulse in terms of other varieties. It is established that in order to obtain stably high yield (44.4-45.4 t on ha) and marketability of root crops (85-93%) in the conditions of the Right-Bank Forest-Steppe of Ukraine it is necessary to sow highly productive varieties of parsnip sowing Stymul and Pulse.

The article presents the results of spring barley crops and the effect of foliar fertilization on them. Prospects and effectiveness of biological products as a basic fertilizer for cereals. Spring barley is a valuable food, fodder and technical crop. Pearl barley and barley groats are made from vitreous and coarse-grained two-row barley grain. Most barley is used for feed purposes. In 1 kg. grain contains 1.2 feed units and 100 g of digestible protein. Spring barley contains a lot of protein (9-12%), carbohydrates (70-75%), pentazoles (7-11%), sucrose (1.7-2%), fiber (3.8-5.5%), fat (1.6-2%), ash (2-3%). Spring barley grain is characterized by high nutritional value and is widely used in feed production, confectionery, brewing. However, in the dynamics of its yield there are significant fluctuations, which is associated with both agro-climatic conditions and organizational and economic. Having a short growing season, underdeveloped root system, the culture is quite demanding on the provision of basic factors of plant life, including nutrients. The system of fertilization of spring barley is determined primarily by predecessors. It has a valuable ability to make the best use of the aftereffects of organic and mineral fertilizers applied to the previous crop. If spring barley is sown after well-fertilized row crops (sugar beet, potatoes), under which 40-50 t / ha of manure and mineral fertilizers are applied within N80P80K80 - N120P120K120, then fertilizers are not applied directly under barley at all. Against this background, barley with proper care can form 40-50 kg / ha of grain. It is clear that in case of incomplete supply of sugar beets or potatoes with fertilizers, barley will require additional application of macronutrients. Barley responds very well to fertilizer application, especially in conditions of sufficient moisture. The increase in yield from mineral fertilizers can reach 15-20 kg / ha. To prevent lodging of plants, it is necessary to ensure the correct ratio of nutrients - nitrogen, phosphorus and potassium. Given the condition of the soil cover and low volumes of fertilizer application, we consider the issues of optimization of mineral nutrition of spring barley to be relevant and in need of refinement. An important component of the plant nutrition system is the use of microfertilizers. Therefore, the purpose of our research is to establish the reaction of spring barley to the complex use of microfertilizers, crop formation and grain quality in the conditions of the Right-Bank Forest-Steppe of Ukraine [3] Key words: spring barley, foliar feeding, biological products.

It was found that the climatic conditions of the introduction area have significant differences between climate indicators (thermal regime indicators and others) with the climatic conditions of natural habitats of climbing honeysuckles species of the subgenus Chamaecerasus, which negatively affect the rhythm of development and flowering and fruiting of introduced plants. It was determinated that the generative period of climbing honeysuckles of the subgenus Chamaecerasus in the arboretum occurs at 4–6 years of age. Most of the introduced honeysuckle was characterized by good (4 points) and satisfactory (3 points) flowering. Representatives of the subsection Breviflorae Rehd. were characterized by long and remontant flowering. It was found that the dynamics of daily fertility of honeysuckles pollen from different areas is closely related to the daily course of flower bloom- ing and daily flight activity of pollinating insects. The duration of the period of fruit formation of introduced honeysuckles depends on the time of the beginning of flowering of species and their geographical origin. Determined amount of positive temperatures above 0 °C required for mass ripening fruit honeysuckles different geographical origin. The plants bear fruit single fruits with empty seeds (ball bearing 1). The collection of climbing honeysuckles of the subgenus Chamaecerasus was created in the National Dendrological Park «Sofiyivka» of the NAS of Ukraine, it has significant scientific and informative value as collector' s stuff is valuable gene pool for further breeding work. The optimal forms of conservation and cultivation of biodiversity of round honeysuckle of the genus Lonicera L. in the one-species gardens and other artificially created phytocenoses have been determined.

In the soil and climatic conditions of the Right Bank Forest-Steppe, regardless of the action of abiotic and biotic factors during the growing season, high adaptability of alfalfa was established for different geographical origins, namely the natural zone of the Forest-Steppe, Polissya, Steppe Ukraine and Serbia. It was found that under the weather conditions of 2016 year alfalfa varieties reacted differently to changes in temperature and moisture during the growing season. It is important to note the effectiveness of phosphorus-potassium fertilizers applied directly to alfalfa coverless method of sowing. In the year of sowing, alfalfa formed a powerful herbage and provided two slopes with a yield of green mass at the level of 20,13-29,80 t/ha with a dry matter yield of 4,80-6,69 t/ha. For the second year of vegetation, alfalfa was carried out according to the regimes, which considered the phases of growth and development (budding, beginning of flowering and flowering). In the first mode of cutting management (all slopes in the budding phase) it is advisable to identify three varieties of Unitro, Nasoloda and Rosana, which provided a gross dry matter of 10,41-10,48 and 2,29-2,31 t/ha of crude protein. The productivity of alfalfa increased with late term cutting - at the beginning of flowering and a combination of slopes (3rd mode). The dry matter yield was 11,40-12,62 and 2,35-2,51 t/ha of crude protein (second regime) and the indicators increased under the third regime, especially dry matter 13,58-15,80 t/ha and decreased to 2,37-2,41 t/ha of crude protein. The increase in dry matter of the second mode increased by 9,5-23,1% and crude protein by 2,6-20,5%, and in the third mode of use of alfalfa it was 2,3-11,2%, compared to the mode of mowing the grass in the budding phase. During the third year of vegetation under favorable agroecological conditions for growth and development of alfalfa plants, the studied varieties provided four slopes regardless of the mode of use of grass with a dry matter yield of 15,43-20,58 and 3,21-4,02 t/ha of crude protein. During the second and third years of vegetation from the studied modes of use of alfalfa grass for fodder purposes, the highest yield of crude protein 5,27-6,53 t/ha varieties provided for the alienation of crops at the beginning of the flowering phase, which was on average 6,0-7,1% higher than when mowing all slopes in the budding phase and a combination of slopes in the phases of growth and development (3rd mode). Thus, in the conditions of the Forest-Steppe of the right bank on gray forest soils alfalfa, regardless of geographical origin, adapted to growing conditions and provided stable productivity indicators regardless of the regime of grass use with observance of elements of cultivation technology.
