In order to obtain a significant level of yield of table carrots in the Right-Bank Forest-Steppe of Ukraine, it is necessary to select varieties and hybrids in accordance with the soil and climatic conditions of cultivation. The comparative estimation of productivity of hybrids of carrots of table foreign selection in the specified conditions is carried out. The results of phenological observations of plant development, their biometric indicators depending on the genetic features are presented. The indicator of the total yield of table carrots according to the experiment was in the range of 65.6–80.7 t/ha. Saturno F1 had higher and this exceeds the control of Abaco F1 by 15.1 t/ha. In the structure of the yield of this hybrid marketable products are 96.0 % or 77.1 t/ha, which is more than the control of 5 % or 17.1 t/ha. In Saturno F1 non-marketable products 3.6 t/ha, which is 2.0 t/ha less than the control, and the yield of standard products 75.3 t/ha, which is a larger indicator of the experiment and exceeds the control by 17.3 t/ha. Non-standard products amounted to 1.8 t/ha. The productivity of table carrots is significantly influenced by the weight of the root, which, in turn, is affected by its length and diameter. On average, according to the years of research, their weight was at the level of 190–240 g. The roots in Abaco F1, which was the control, were smaller in weight. Larger roots formed in Saturno F1. Hybrids Baltimore F1, Bolivar F1 and Gerada F1 formed roots of 208 g, 218 g and 233 g, respectively. The diameter of the roots of the studied carrot hybrids was 4.6–5.2 cm. They were smaller in Saturno F1 and larger in Baltimore F1. The average values of root diameter for the years of study in Abaco F1 (control) are 5.1 cm; Bolivar F1 4.7 cm, and Gerada F1 5.0 cm, which is less control by 0.4 and 0.1 cm, respectively. An important varietal feature of table carrots is the length of the root. In Abaco F1 it was 18.5 cm. This is the lowest value in the experiment. In Baltimore F1 and Bolivar F1 the roots were formed of almost the same length 19.0 and 19.3 cm, respectively, which is more control by 0.5 and 0.8 cm. In Gerada F1, the roots were 23.2 cm, which is more control by 4,7 cm. Roots of Saturno F1 were longer compared to other variants of the experiment 24.5 cm, which is more control by 6 cm. The suitability of the studied hybrids of table carrots for foreign selection for growing in the conditions of the Right-Bank Forest-Steppe of Ukraine has been established.

Abstract Growing fruit trees is a long term financial commitment and establishing an orchard is an expensive enterprise. Selecting the right orchard site is arguably the most important decision that a sweet cherry grower will make and it will affect all other managerial decisions related to the orchard. Choosing the wrong site can affect both fruit yield and quality, and ultimately the financial viability of the operation. On the other hand, choosing a good site will reduce expenses and increase profits. Properly evaluating a prospective orchard location, determining available resources and establishing the orchard takes careful planning. This chapter focuses on important factors in planning a new cherry orchard, including economics and site evaluation (climatic conditions, topography, soil characteristics, soil analysis, water availability and quality, access to key auxilliary facilities, and environmental impact).

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.

Long-term studies (2014–2019) of the population dynamics of the fungus Rhizoctonia solani Küch. were carried out in the soil on the Purple Majesty, Vitelotte and Fioletovy potato varieties and preceding crops (potatoes, oats and tendergreen). The study was carried out in Novosibirsk region in the soil and climatic conditions typical of the forest-steppe zone of Western Siberia. To study the peculiarities of R. solani fungus population dynamics in potato plantations, soil samples were taken from under the plants during the entire growing season. The accumulation of rhizoctonia propagules in the soil was determined using the method of multiple soil pellets. The difference in the amount and rate of accumulation of the fungus R. solani on different varieties, as well as the influence of previous crops on this process, was established. Two peaks of the fungus accumulation were observed on the Purple Majesty variety: the first (48.7 propagules/100 g of soil) – during the full germination period, the second (57.2 propagules/100 g of soil) – at the end of the crop maturation phase. One peak was observed in the population dynamics of the fungus on Vitelotte and Fioletovy varieties, at the end of the ripening period (59.0 and 49.1 propagules/100 g soil, respectively). The smallest amount of R. solani fungus in the soil on average during the growing season was noted on the Fioletovy variety – 33.3 propagules/100 g of soil. In the Purple Majesty and Vitelotte varieties, this figure was 41.5 and 40.4 propagules/100 g of soil, respectively. When potato variety Agata was cultivated as monoculture, there was a rapid and significant accumulation of the fungus R. solani in the soil (from 34.6 to 126.8 propagules/100 g of soil). When this variety was cultivated following tendergreen or oats, the amount of the pathogen varied to a lesser extent (25.1–52.2 and 19.8–41.0 propagules/100 g of soil, respectively). No sharp increases in the number of propagative structures of the phytopathogen in the soil were noted.

Importance of the territory climatic conditions as unpredictable dynamic changes problem that forms a threat to the development of the agricultural sector of the country was investigated. The problem comes from the fact that for food security of agricultural ecosystem it is rather vulnerable to change of climatic parameters, and agriculture belongs to branches which are especially sensitive to climatic changes impact. We analyzed long-term data figures for the period 1995 to 2014, which describe the temperature and moisture regime of Lubny (Poltava region). The main trends and patterns of their dynamics were established, the degree of deviation from the long-term norm was given. The author determined the relationship of the territorial climatic conditions changes and agricultural ecosystem performance and stability and also the potential consequences of the adverse effects. As a result, it was found that the expansion of the growing season crops, due to the increase in temperature and the average value of the classical heat supply plant index, may impair the stability of the agricultural ecosystem complex and reduce its performance. At the same time, one of the adapting agricultural production ways to climate change, which does not require any additional costs, is to optimize the placement of crops due to the harmonization of the production specialization ratio in accordance with the area conditions.

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.
