Сорти льону олійного мають важливе значення для отримання його стабільного врожаю високої якості. Проте для льону олійного виявлена ​​значна варіабельність ознак насіннєвої продуктивності (кількість та маса насіння з рослини, маса 1000 насінин) і біохімічного складу насіння, однак відомості про реалізацію генотипового потенціалу культури обмежені. Саме через таку мінливість ознак льону олійного метою нашого дослідження було порівняння морфології рослин різних сортів під час вирощування саме в умовах Правобережного Лісостепу України. Проведені дослідження показали, що умови вирощування мають вплив на такі генотипові ознаки як висота рослин та кількість коробочок на рослині. Маса 1000 насінин та кількість насінин у коробочці є відносно стабільними показниками і мають незначну мінливість. Маса насіння з однієї рослини залежить від кількості коробочок на рослині, про що свідчить високий коефіцієнт кореляції. Найбільшу висоту рослин за всі роки досліджень мав сорт Лірина, найменшу – сорт Айсберг. Найвищу масу 1000 насінин мав сорт Південна ніч. Кращими за продуктивністю однієї рослини в умовах Правобережного Лісостепу України виявились сорти Еврика, Лірина та Блакитно-помаранчевий. Linseed varieties are of great importance for obtaining stable yields of high quality. However, for linseed, there is a significant variability in the signs of seed productivity (amount and mass of seeds from the plant, mass of 1000 seeds) and biochemical composition of the seeds, but information about genotypic potential realization of the culture is limited. It is because of this variability of linseed characteristics our study was aimed at comparing morphology of plants different varieties during cultivation precisely in conditions of the Right-bank Forest-Steppe of Ukraine. Studies have shown that growing conditions affect on such genotypic signs as height of the plants and number of fruitcases on the plant. Weight of 1000 seeds and number of seeds in the fruitcase is relatively stable and has insignificant variability. Weight of the seeds from one plant depends from number of fruitcases on the plant, as evidenced by the high correlation coefficient. The biggest height of the plants during the all years of research has variety Liryna, the shortest – variety Aisberg. The highest weight of 1000 seeds has variety Pivdenna nich. The best by productivity of the one plant in conditions of Right-bank Forest-Steppe of Ukraine were varieties Evryka, Lirina and Blakytno-pomaranchevyi.

The article presents the results of the research dealing with the dependence of the mass, growth processes and the attachment height of the low bean of soybean under the application of different types of fungicides and biopreparation Rhizoactive in the Right Bank Forest-Steppe of Ukraine. Application of different types of fungicides had a positive influence on the plant mass of soybeans, growth processes and attachment height of a low bean. Indexes were defined in different years and at different development stages of a plant: budding, flowering and beans maturing. Throughout all development stages, the best indexes of soybeans height, their mass and attachment height of a low bean were under the complex application of preparations, in particular, the highest indexes were in the variants with the application of fungicides Impact K, 0,9l/ha; Koronet 300 SC, KC 0.8 l/ha at the background of seeds treatment with the inoculator Rhizoactove. Important selection features that are associated with the main morphological and biological characteristics of soybeans are the height, mass and lower bean attachment height of soybean. Productivity in general depends on the height and weight of plants, as the stem is an organ of conversion and transport of organic and mineral substances, which plays an important role in crop formation. Technology of soybean cultivation on irrigation provides suitability of varieties for mechanized harvesting, including resistance to pod shatter and lodging, optimal placement of the first beans on the plant and genotypes reaction to irrigation. For successful introduction into production, new soybean varieties must be not only high yielding but also suitable for mechanized harvesting, which is primarily due to the lower bean attachment height of the plant. Low first bean attachment leads to a decrease in the yield of the variety, since a significant number of beans are lost during combine harvesting. Yield losses because of the low attachment of the lower bean may reach 15-20%. This feature is associated with the total height of the plant. The height of soybean plants and the lower bean attachment largely depend on growing conditions. The research conducted by A.Ya Ala. and A.A. Hamolin have established that linear parameters of plants at irrigation considerably increase. In the south of Ukraine irrig

Purpose. To assess the relationship between distribution, microrelief structure and regenerative dynamics of meadow phytocenoses on slope lands and to establish the productive potential of renewable herbage with different methods of their grassing in the conditions of the right-bank Forest-Steppe. Methods. Field and laboratory research in grassland, hypothesis, dialectical, synthesis and analysis, induction, statistical. Results. A strategy was theoretically developed for restoring the forage grasslands on slopes, which provides for the selection of the most adapted species with high biological characteristics, their ecological and phytocenotic combination in highly productive mixtures, and development of ecologically safe technologies for the reconstruction of such lands on the basis of theoretical provisions on the demutational dynamics of herbal phytocenoses. The species of legumes and cereal grasses were selected for the research, which, according to their biological characteristics, are valuable fodder, medicinal, melliferous, soil-protective and phytomeliorative crops. It was found that in terms of phytocenotic properties, 40% of the species of the Poaceae family exhibit dominant properties, 40% are among the main cenose-formers, 20% are dominants in narrowly limited ecological conditions. It was revealed that the ecological structure of populations of natural phytocenoses of slopes most often consists of one dominant species and two subdominants, which are in certain proportions. Direction of the ecological strategy for the development of each species has been established and a ranked series has been constructed according to the indicators of the cenotic activity index. Renewable legume agrophytocenoses have the greatest potential for productivity with superficial or radical improvement, which in the seasons of use in 2019-20 provided the yield of green mass at the level of 27.03-47.33 t/ha and dry matter – 6.31-10.32 t/ha. Conclusions. When selecting the species composition of renewable perennial phytocenoses, it is necessary to use ecological-biological and phytocenotic approaches, according to which the species should be evaluated according to their adaptability to growing conditions, coenotic power, competitive ability, association and productivity. The best ecological resistance to growing conditions and the value of the production potential was shown by restorative grass stands based on leguminous grasses of the raised type of development.

У статті обґрунтовано необхідність вивчення проса прутоподібного (світчграсу) як енергетичної культури, сировину якої доцільно використовувати для виробництва різних біопалив: рідких, твердих та газоподібних. Матеріалом для дослідження були рослини та насіннєвий матеріал сорту проса прутоподібного іноземної селекції Кейв-ін-рок. Здійснено спробу визначити оптимальні умови (за гідротермічним коефіцієнтом і з урахуванням родючості ґрунтів) для отримання високого врожаю насіння в умовах України та шляхи підвищення його посівних кондицій. За результатами трьохрічних досліджень встановлено вплив погодних умов веґетаційного періоду на продуктивність насіння проса прутоподібного. Експериментальним шляхом визначено лімітуючі фактори та шляхи їх нівелювання для забезпечення гарантованого отримання якісного насіннєвого матеріалу в умовах Лісостепу. Аналіз результатів досліджень дав змогу встановити вплив біометричних (кількісних) показників генеративної частини рослин (довжини та кількості волотей на рослинах, маси 1000 насінин) на насіннєву продуктивність, що обумовлюють і загальний урожай насіння. Визначено вплив крупності насіннєвого матеріалу та терміну зберігання його на лабораторну схожість насіння у взаємозв’язку з особливостями його формування на материнських рослинах за різних умов вирощування. Necessity of studying switchgrass as an energy crop, raw material of which may be used for producing different types of biofuel such as liquid one, solid and gaseous ones has been substantiated in the article. The foreign experience of obtaining switchgrass seed of high quality has been investigated on the basis of scientific publications. We have established the limiting factors affecting seed yield, sowing characteristics, germination conditions, growth and development of plants in the early periods of vegetation. The attempt of determining optimal conditions (by hydrothermal coefficient and soil fertility) for providing high seed yield in Ukraine as well as ways of increasing seed characteristics has been made. Many years’ experiments were conducted in the central part of Forest-Steppe of Ukraine on two types of soils: high-productive soil with humus content of more than 4 % and nutrient lean soil with humus content of less than 2 %. Research material was plants and seed of Cave-in-Rock switchgrass variety of foreign selection. The methods of testing, field and laboratory experiments, scientific recommendations were applied in the experiment. The experimental results were processed by the dispersion analysis and correlative-regression analysis with application of the computer program Statistics. After three years of investigation, influence of the vegetation period weather conditions on switchgrass seed productivity has been established. The limiting factors and the ways of decreasing their effect in order to provide guaranteed getting of high quality seed material in the conditions of Forest-Steppe of Ukraine have been defined by the experiments. At the same time the effect of soil conditions on the crop seed productivity has been proved. The analysis of the research findings enabled to show influence of biometric (quantitative) characteristics of the generative plant part (length and number of panicles per the plant, mass of 1000 seeds) on seed productivity that affect total seed yield. Besides, influence of seed material size and storage period on laboratory seed germination in the interconnection with seed formation peculiarities on maternal plants in different cultivation conditions has been determined. The yield of switchgrass seeds depends on weather factors and soil fertility. Also we defined influence of quantitative characteristics in the generative plant part – length and number of panicles per the plant, mass of 1000 seeds on seed yield. Laboratory germination of seeds depends on the storage size and the mass of 1000 seeds.

The results of 35-year research of the introduction of East Asian climbing honeysuckles of the subgenus Chamaecerasus Rehd. in the Right-Bank Forest-Steppe of Ukraine and their role in optimizing the structure of phyto- cenoses of the The National Dendrological Park «Sofiyivka» of the NASU were presented. 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.

Purpose. Determine the oil content and glucosinolate content and productivity of spring camelina and spring rapeseed as affected by varietal characteristics. Methods. The research was conducted in the educational-scientific-industrial complex of Uman National University of Horticulture. Spring rapeseed varieties ‘Belinda’, ‘Aidar’, ‘Heros’, ‘Jerry’ and spring camelina varieties ‘Zevs’, ‘Hirskyi’, ‘Slavutych’, ‘Mirazh’ were studied. Seeds were sown in a row to a depth of 1.5 cm with a seeder CH-16. The sowing rate was 300 seeds/m2, or 5.4 kg/ha. The crop was harvested separately by Sampo-500 combine. Results. In spring rapeseed, the highest yield was marked by variety ‘Aidar’ (2.52 t/ha) and the lowest by ‘Heros’ (2.43 t/ha). In spring camelina, the highest yield was in variety ‘Zevs’ (2.31 t/ha) and lower in ‘Hirska’ (2.15), ‘Mirazh’ (2.27), and ‘Slavutych’ (2.22 t/ha). The highest oil content among rapeseed varieties demonstrated ‘Aidar’ (43.7%). Slightly lower it was in ‘Belinda’ (43.2%), ‘Jerry’ (42.8) and ‘Heros’ (42.6%). Depending on the varietal characteristics, the highest percentage of oil content was found in spring camelina varieties ‘Zevs’ (45.1%). It was lower by 0.5 and 0.9% in ‘Mirazh’ and ‘Slavutych’. The lowest percentage of oil content (43.7%) was determined in camelina variety ‘Hirska. In spring rapeseed varieties, the highest content of glucosinolates was in ‘Aidar’ – 20.5 μmol/g, 0.3 and 0.5 μmol/g less in ‘Belinda’ and ‘Jerry’, and the lowest in ‘Heros’ (19.8 μmol/g). In spring camelina, the highest value was in the variety ‘Zevs’ (22.0 μmol/g), and the lowest in ‘Hirska’ (21.0 μmol/g). ‘Mirazh’ and ‘Slavutych’ contained 21.7 and 21.4 μmol/g of glucosinolatesm respectively. Conclusions. The productivity of oilseed crops varies under the same growing conditions: spring rapeseed, regardless of varietal characteristics, demonstrated higher yield compared to camelina. On average over the years of research and varieties, this indicator was 2.47 t in spring rapeseed, and 2.24 t/ha in spring camelina, which is 0.23 t/ha less. In rapeseed, the oil content of the seeds was 43.07%, the content of glucosinolates varied from 19.8 to 20.5 μmol/g. In spring camelina, the oil content of seeds was 1.33–44.40% higher, the content of glucosinolates ranged from 21.0 to 22.0 μmol/g. The level of profitability of the studied oilseed crops was high and varied as affected by varietal characteristics: in rapeseed from 122 to 141%, and in spring camelina from 182 to 196%.

Seed treatment with boron and molybdenum and rhizotorphine helped to increase the length of the stem. It generally provided better aeration of crops due to better light, which amounted to 87.9 cm for boron treatment and 88.5 cm for molybdenum treatment, increasing the number of seeds in beans from 7 to 8 pcs. However, the weight of 1,000 seeds decreased slightly, both for boron treatments up to 156.5 and for molybdenum treatments up to 154.3 g. In addition, the use of foliar fertilizers Nanovit Mono Bohr in the budding phase contributed to increasing the length of the stem to 91.2 cm, the number of seeds in beans to 9 pcs, the weight of 1,000 seeds to 161.4 g, and the yield level to 7.5 t / ha. In order to obtain the maximum yield of peas vegetable varieties of Skinado and Sommerwood at the level of 7-8 t / ha in the conditions of Vinnytsia it is necessary to add mineral fertilizers N40K60R60, (phosphoric and potash - under the basic cultivation of soil, nitrogen - under pre- sowing cultivation). Before planting vegetable peas, seed treatment with risotrophin, boron, molybdenum and as extra-root nutrition is carried out by Nanovite Mono Bor - 1 l / ha and Molybdenum Nanovite - 0.5 l / ha in the budding phase. Treatment of seeds with boron and molybdenum contributes to increasing the length of the stem, which in general provides better aeration of crops due to better lighting. Further study of the factors of intensification of the technology of growing vegetable peas, in particular, on the implementation of foliar infusions in the phase of seeding began to be needed.

The article presents the data of the field research on the influence of sowing terms with the temperature regime of soil and sowing rates of soybean seeds of Omega Vinnytsia type in the conditions of the Forest Steppe of the Right Bank. It has been determined that sowing terms with the temperature regime of soil at a depth of 10 cm from 6,8,10 and 12 ° C have different effects on growth processes and formation of generative organs on the plant. Optimal sowing periods were the most favourable for intensive growth and development of soybean plants were temperature conditions within 8 and 10 ° C. Sowing at a soil temperature of 10 cm at a depth of 6 ° C reduced the stem height at all seed rates. The height of the lower bean attachment was reduced, as well as the number of beans on the plant and seeds in the bean, while the safety of plants during harvesting was also reduced. Intensive initial growth of soybean crops at sowing at 12° C resulted in increased attachment of lower beans to the stem, but the number of beans per plant and the number of seeds in a bean decreased significantly. The research of the efficiency of sowing soybean types Omega Vinnytsia 600, 700, 800 and 900 thousand germinated seeds per 1 hectare shows at a rate of 600 thousand pieces, stem height, because of their branching, was lower than at the sowing of 700 and 800 thousand n / ha. Also, the height of the lower beans, the number of beans per plant and the number of seeds in the bean were reduced. The highest biometric indicators and the number of generative organs on the plant were observed during sowing with the sowing rate of 700 and 800 thousand n/ha. The increase of soybean seed rate up to 900 thousand n / ha deteriorated biometric indicators of plants and the formation of generative organs. The survival of plants increased at sowing in 6 ° C of soil temperature and with an increase in sowing rate above 600 thousand n / ha. The weight of one thousand seeds changes to a lesser extent depending on the timing of sowing and seed rate and its high indicators were noted at sowing in 8 and 10 ° C and seed rate 700 and 800 thousand n / ha. Increase of soybean seed rate up to 900 thousand n.p. / ha reduces the weight of 1000 seeds against other seed rates for 8-10 years. Years of research were favorable for growing soybeans and obtaining high levels of seed yields. The highest yield of soybean seeds of Omega Vinnytsia variety was obtained at the sowing rate of 10 ° C and it was at the rate of 600 thousand soybean seeds / ha - 36.0 centners / ha; 700 thousand soybean seeds - 44.7 centners / ha; 800 thousand soybean seeds / ha - 40.0 centners / ha and 900 thousand soybean seeds / ha - 38.2 centners / ha. The approximate yield of seeds was obtained at sowing at 8 ° C according to all norms of sowing of seeds in the same regularity as at sowing at 10 ° C. Increase of sowing rate up to 900 thousand n/ha leads to increase of seed yield but also to overspending of seeds and considerable decrease of individual productivity of plants. At the same time, sowing at soil temperature of 6 ° C was more effective than sowing at 12 ° C. and yield was at a rate of 600 thousand seeds. At the same time, sowing at soil temperature of 6 ° C was more efficient than sowing at 12 ° C, and the yield was at the rate of 600 thousand seeds - 27.4 centners / ha, 700 thousand seeds / ha - 33.8 centners / ha; 800 thousand seeds / ha - 29.7 centners / ha and 900 thousand seeds / ha - 30.6 centners / ha. And when sowing at 12 ° C, respectively, 26.4, 31.5, 29.1, 29.2 centners / ha. Key words: sowing dates, sowing rates, plant height, lower bean attachment height, number of beans per plant, number of seeds, seed weight, yield.

Methods. Field (to study the interaction of the object of study with biotic and abiotic factors), test sheaf (to determine the individual productivity of plants), harvesting (to determine the seed yield), statistical (to determine the probability of research results), comparative calculation. Results. According to the research results, the most favourable conditions for the optimal parameters of plants individual productivity formation of early-maturing soybean of the Vilshanka and medium-ripening Suzirya varieties were created due to the seeds inoculation by phosphonitragin and mineral fertilizing in the dose of N30P60K60 + N15 in the phase of budding, what positively affected the level of yield as a whole. Conclusions. The technology model for intensive growing of the Vilshanka and Suzirya soybean varieties, which involves the use of seeds inoculation by a bacterial preparation based on strains of nodule bacteria (Br. Japonicum) and phosphate-mobilizing microorganisms (B. mucilaginosus) and introduction of N30P60K60 in the main fertilizing and extra-feeding with N15 provided the highest values of individual and seed productivity: the number of beans (24.7 and 28.8 pcs/plant, respectively), the number of seeds (51.0 and 56.1 pcs/plant), the weight of 1000 seeds (147.2 and 144.6 g), yield (2.91 and 3.17 t/ha). The organized factors ensured the optimal height of the lower bean attachment on the plant, which had a positive effect on yield preservation and facilitated mechanized harvesting. Improving the technology of growing the Vilshanka and Suzirya soybean varieties on the basis of bacterial and mineral nutrition has led to the highest level of profitability, respectively 124 and 160%, and energy efficiency ratios (2.20 and 2.40).

Sweet pepper takes one of the main places in the human diet among all vegetable plants. By the content of healthy vitamins, sweet pepper fruits have a better effect on the absorption of food than greenhouse cucumbers and tomatoes, and therefore sweet pepper is in great demand among consumers. The difference in the biometric and physiological parameters of sweet pepper of different age seedlings depends on the duration of growing seedlings. For the study, a sweet pepper variety of domestic selection Aphrodite was used. At the same time, biometric determinations were carried out over the sweet pepper plant: seedling height, stem diameter before planting, plant mass. The observation method monitored the onset of phenological phases of plant growth and development, and a laboratory method was used to determine biometric parameters. The appearance of the first leaf was established with clear control of the microclimate parameters and the provision of an appropriate irrigation regime. The formation of the first leaf was observed on the 7th day after emergence. It was proved that the formation of subsequent leaves, the growth of vegetative mass depended significantly on the age of the seedlings: the higher the seedling age, the more real leaves formed, due to the accumulation of dry matter in the leaves and the corresponding nutritional and temperature conditions. At the time of planting seedlings in open ground, at a constant place of vegetation, the plants were characterized by the presence of 4-6 real leaves, the height of the seedlings was 12-15 cm with a total weight of 10-12 g, there were no damage by pests and diseases on the surface of the leaves. As a result of different age of seedlings, studies have established that with a decrease in the age of seedlings, a tendency to delay flowering and fruiting was observed. The age of seedlings directly affects the budding of plants. So, in the variant where the seedlings are 60 days old, the period of budding was observed for 56 days, which was observed 1 day earlier than the control variant. Seedlings of sweet pepper aged 50 and 70 days passed into the budding phase for 57 days. However, seedlings aged 40 days showed a tendency to delay the onset of plant budding. It has been established that the height of the plant before planting ranged from 14.7 cm to 18.6 cm. The highest rate of plant growth has been distinquished in the variant where the seedlings were 70 days old. When using the seedling age of 70 days, the test value was 2 controls more than the control index. The option using 60 day old sweet pepper seedlings was characterized by slightly low leaf numbers. The experiments established that when using seedlings with an age of 40 days, the plants were characterized by the smallest number of leaves on the plant. The age of seedlings and biometric indicators depend on the growing conditions, the timely passage of the photosynthesis process, the provision of nutrients, water. When using the seedling age of 60-70 days, the biometric indicators of seedlings, namely the height of the plants, the number of glosses, the mass of the plant significantly exceeds the biometric indicators of seedlings with an age of 50 or 40 days. Keywords: sweet pepper, Aphrodite variety, seedling age, biometrics, vegetation, Right-Bank forest-steppe.
