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.

Chickpeas are a valuable legume and drought-resistant crop. In conditions of climate change, it ensures the formation of a sufficiently high yield, which increases the interest of agricultural producers in growing crops. However, the presence of genetically determined plant protection (pubescence of plants and pod, which contain oxalic, malic and citric acids) from some pests makes it possible to grow environmentally friendly products, which consequently reduces the need to use plant protection chemicals. Field experiments were carried out on the experimental field of the Uman National University of Horticulture in the soil and climatic conditions of the Right Bank Forest-Steppe. To determine the selection value of collection varieties samples of domestic selection were grown. It should be noted that plants react significantly to extreme conditions (temperature and amount of precipitation) of cultivation precisely in the period from gathering to flowering. It is during this period of time that excess moisture leads to shedding of flowers and, as a result, to a decrease in yield. The meteorological conditions for growing crops, which are expressed in the duration of both the growing season as a whole and its individual phases, have a significant effect on the length of the growing season. And so, according to our data, it was revealed that the difference in the duration of the growing season of the studied selection samples in comparison with the standard was small and ranged from 3 to 5 days. The main indicator of adaptability to mechanized harvesting is the attachment height of the lower pod. It depends on the height of the plant itself and the shape of the bush that the culture forms. On the basis of average, it was revealed that the studied selection samples belong to tall plants, while the indicator of the attachment height of the lower pod, the Triumph standard had a high attachment of pod, two samples – moderate, which indicates the possibility of mechanized harvesting, while samples 230 and 210 – low. As a result of comparison of the obtained data on the yield of selection samples, their significant reaction to the growing conditions was revealed. Analysis of the average data helps to specify that the highest yield in the conditions of both 2019 and 2020 was provided by selection samples 180 (morphotype desi), while the lowest yield, but also within the standard, was found in sample 160 (morphotype gulabi)

The results of the use of a yeast preparation on sunflower crops for 2016-2017 have been presented. A positive effect of the researched preparation on the growth and development of sunflower crops of the Neoma hybrid has been established. The preparation Rostmoment increased the height of sunflower plants with a single treatment by 6 cm, and with a two-time treatment of crops by 11 cm, the diameter of the baskets increased by 2.0 cm and 6.3 cm, respectively, against untreated crops. The mass of thousand achenes has been increased by 0.7 g with a single treatment and 2.2 g with a double treatment. The oil content during one-time processing in the basket formation phase was 50.7%, when used twice in the phase of flowering, 51.9%, while in the control its content was 49.2%. Weather conditions in the years of the study significantly affected the productivity of the sunflower of Neom hybrid, especially in terms of moisture supply, and the best conditions for the study of the crop were in 2016, where 209 mm fell during the growing season. precipitation with a uniform distribution. The temperature regime of air on average over the period of sunflower vegetation was 16.5 ºС. The weather conditions of 2017 significantly differed in the amount of precipitation, their distribution and temperature regime, versus 2016. Thus, in 2017, 374 mm of rain fell in the form of prolonged and heavy rainfall, which were unevenly distributed over the decades and months. Such weather conditions caused alternation of excessive moisture and drought during certain periods of growth and development of sunflower plants of the Neoma hybrid, while the average air temperature was 16.2° C. Under such extreme conditions of vegetation periods in the years of research, on average for two years, the yield of sunflower seeds on an untreated experiment was 3.32 t / ha and oil yield 1.64 t / ha. The 2016 yield was slightly higher, 3.43 t / ha and an oil yield of 1.43 t / ha. The use of Rostmoment during a one-time treatment in the basket formation phase led to an increase in yield over two years, which amounted to 3.63 t / ha, and in 2016 - 3.82 t / ha. The use of the studied drug even in the phase of the beginning of flowering contributed to an increase in the yield of seeds in two years to 3.89 t / ha, and in a more favourable 2016 - 4.02 t / ha. The average oil yield per hectare over two years for a one-time treatment of plants was 1.87 t / ha, and for a two-time treatment it was 2.02 t / ha, whereas in 2016 these figures were respectively 1.96 and 2.11 t / ha. The research having been conducted for two years indicated the positive effect of the yeast preparation Rostmoment on sunflower crops, which positively influenced the growth and development of the crops and increased the productivity of the Neoma hybrid in the conditions of the Right-Bank Forest-Steppe. The obtained results are of practical value and can be used by producers in the development and application of technologies for the cultivation of sunflower for increasing the productivity of crops and the ecological state of the agroecosystem. The preparation Rostmoment must be introduced into vegetation plants in the basket formation phase and in the phase of the beginning of the sunflowers’ blossoming, normally 4 kg per 300 l of water per 1 ha of sowing.

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. Key words: spring wheat, yield, variety, sowing dates, seeding rate.
