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%.

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.

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.

The evaluation of 50 introduced tulip genotypes (Tulipa (L.) in the conditions of the Right-Bank Forest-Steppe of Ukraine were made by the Department of Horticulture of Uman National University of Horticulture into groups, classes, where different varieties, mainly of foreign selection were represented according to their decorative qualities, basic economic and biological features and grouped into a collection. The indicators concerning the phonological phases of development of introduced plants in the context of individual varieties of tulips and on average by years of research carried out and generalized. A brief agrobiological and decorative characteristics of collection varieties in the conditions of the Right-Bank Forest-Steppe of Ukraine, which are included in further research on the cultivation and reproduction of promising varieties is given/ Bulbs of all introduced varieties were planted in late September, namely on the 25th-27th, so that they would be fully rooted. before the first frosts, It should be noted that first of all, small fractions of bulbs were planted, sticking them into the loose soil at the bottom of the furrow made only with a distance of 6–8 cm from each other. However, we also took into account the factor that small bulbs were planted somewhat denser at depth, which is usually three times the height of the bulb. The plant survival stage was completed within 2–3 weeks. For processing we have chosen a site in the botanical nursery of the Department of Horticulture, where there are no stagnant floods and rainwater. During its preparation, a large fraction of river sand was applied for better moisture throughput, and with a small excess it can be easily removed. Later, when the soil actually freezes to a small depth, namely 1–3 cm, the experimental area was mulched with 3–5 cm sawdust and in the spring the mulch was raked. The experimental area was completely protected from cold winds, which in turn didn’t shorten the flowering period and didn’t actually weaken the plants. Field observations on the resistance of different varieties of tulips to gray rot in the Forest-Steppe of Ukraine were carried out and it was found that the infection of the studied genotypes was at a low and very low level, despite the contrasting conditions of different years of study. In early spring seedlings were sprayed with fungicides to prevent gray rot.

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.

Purpose. To establish the peculiarities of growth and development and formation of productivity of Savoy cabbage varieties (Brassica sabauda Lizg.) in the conditions of the Right-Bank Forest-Steppe of Ukraine. Methods. The research was conducted in the Research and Production Department of Uman National University of Horticulture in the years 2018–2020. Varieties of savoy cabbage (‘Vertu 1340’ – control, ‘Sphere’, ‘Rozali’ and ‘Vertus’) were planted according to the scheme 70 × 40 cm (35.7 thousand plants/ha). Results. During the sowing of seeds (April 25) on cold ridges in a row method with a row spacing of 10 cm, mass shoots of Savoy cabbage were observed on average in early May (7–8 days), the beginning of head formation – in the middle of August, and their technical maturity in late September. Intensive growth of heads took place in the middle and late August and ended in late September. On average, over the years of research, the largest diameter of the head was observed in the cultivars ‘Vertu 1340’ – 18.7 cm, the smallest in the ‘Rosalie’ – 16.1 cm. at one level – 17.5 and 17.6 cm, respectively. The smallest in height at the level of the rosette and head were plants of the ‘Sphere’ and ‘Vertus’ varieties – 25.4 and 23.4 cm and 26.9 and 24.6 cm, respectively. The control variety ‘Vertu 1340’ was characterized by the highest indicators of height of both the rosette (40.7 cm) and the actual head (36.5 cm). Slightly lower rates were observed in the variety ‘Rosalie’ – 32.9 and 31.8 cm, respectively. The highest yields were formed by Savoy cabbage varieties ‘Vertus’ (53.1 t/ha) and ‘Sphere’ (51.8 t/ha), which exceeded the control variant by 7.4 and 6.1 t/ha, respectively (‘Vertu 1340’ – 45.7 t/ha). The least productive among the studied assortment was ‘Rosalie’ yielding 39.9 t/ha. Conclusions. When grown in the Forest-Steppe of Ukraine, the highest yields of marketable products are formed by Savoy cabbage varieties ‘Sphere’ and ‘Vertus’.

Nowadays pea and soybeans prevail in agrocoenosis among legume in the Right-bank Forest-steppe. In contrast to these crops, the chickpea is more drought-resistant at the same time, it does not lodge, and the beans do not crack when ripe. In this regard, the problem of developing the elements of chickpea cultivation technology becomes important, in particular, the selection of effective measures to protect crops from weeds using herbicides. It is possible to reduce and overcome herbicide stress when using biological preparation of natural origin – microbial drug and plant growth regulators. The experimental part of research was held during 2015–2017 in the field training and production department and research laboratory of the department of microbiology, biochemistry and plant physiology of Uman National University of Horticulture. Accounting and study of plants height and leaf-area duration in experiments were done in accordance with methodologies, described by Z. M. Hrytsayenko and co-authors. Statistical analysis of the results of the studies was carried out using the methods of dispersion analysis, described by B. A. Dospekhov. As a result of the research it was found: the height and area of the leaves of chickpea plants varied both by years and depending on the use of different norms of the herbicide Panda, entrenched separately and against the background of seeds processing PGR Stympo and MD Ryzobophyt. On the average over the years of observation over the independent action of MD Ryzobophyt (1,0 l/t) the plant height of chickpea with regard to control I grew into 2%, leaf-area duration with regard to control I grew into 12 %. At individual action PGR Stympo (0,025 l/t) with regard to control I grew into 16 %. In variants of cooperative usage of MD Ryzobophyt and PGR Stympo increasing of a chickpea height with regard to controls I contained 8 %, the index of leaf-area duration increased with regard to controls I into 20%. At individual usage of the herbicide Panda in limits 3,0 and 4,0 l/g the plant height grew into 1 and 8 %, the leaf-area duration of chickpea increased into 9 and 32% with regard to control I, at limits 5, and 6, l/g – in 4 and 2% the leaf-area duration of chickpea grew into 19 and 14% with regard to control I. While processing by a mixture of MD Ryzobophyt (1,0 l/t) and PGR Stympo (0,025 l/t) and entering the herbicide Panda in limits 3,0–4,0 l/g before the chickpea sowing the height of a crop surpassed the control I on 12 and 19 % , the leaf-area duration of chickpea increased into 39–83 % with regard to the control I, and at limits of entering 5,0 and 6,0 l/g – into 13 and 11 %. The duration increased into 69 – 33 % to control I. The highest indexes of plants height and leaf-area duration were recorded in the Panda herbicide application in limits of introduction 4,0 l/g against the processing of seeds before the sowing PGR Stympo (0,025 l/t) and MD Ryzobophyt (1,0 l/t) in particular, in this embodiment, the height of the plants increased by 19%, the leaf area - by 83%

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.

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)

Methods.Field, analytical and statistical. Results.It was established that among the mid-range varieties Divo stands out with a yield of 42.3 t/ha, Malin white – 39.8 t/ha, and Legend – 37.1 t/ ha. The most favourable weather and climatic conditions for the production of potato tubers were for the Divo 2011 variety with a yield of 45.9 t/ha and 2013 – 45.1 t/ha. For the Legenda variety 2016, the yield of potato tubers is 40.6 t/ha and 2017 – 43.2 t/ha. Malin White 2013 is 41.4 t/ha and 2017 42.1 t/ha. The average varieties of potatoes showed a slightly lower yield on average over the years of research. However, among the varieties is allocated Nadiyna – 40.3 t/ha, Slovyanka – 37.2 t/ ha and Vera 33.8 t/ha. Among the years, the most high-yielding for the Vera variety was 2016 with a yield of 36.6 t/ha and 2017 year – 37.8 t/ha. Varieties Slovyanka and Nadiyna 2011 and 2012 with yields of 42.6 and 44.3 t/ha and 46.5 and 45.3 t/ha, respectively. Characterizing the yield of potato tubers of medium-late varieties over the years of research, there was a decrease in this indicator compared with medium-early and middle-aged varieties. However, the high yield of the varieties of Dar is allocated – 40.0 t/ha, Alladin – 33.6 t/ha and Oxamit 31.3 t/ha. Among the years, the most favourable ones were: for Oxamit and Alladin – 2011 – 33.5 and 36.5 t/ha, and 2017 – 34.1 and 36.4 t/ha, respectively. Favourable years for harvesting varieties were 2011 and 2012 with yields of 45.7 and 45.8 t/ha. Thus, the highest yield of potato tubers on average over the years of studies of medium-early varieties of 41.2-43.3 t / ha were provided by weather conditions of 2011 and 2017 years, medium-ripe varieties 41.0-41.1 - 2012 and 2011, medium- late 37,6-38,5 t / ha - 2012 and 2011, respectively.
