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’.

Purpose. To establish the optimal row spacing and so­wing rate of sorghum seeds of grain varieties ‘Dniprovskyi 39’ and ‘Vinets’, to substantiate their influence on the growing season and biometric parameters of plants in the Right-Bank Forest-Steppe of Ukraine. Methods. Field, laboratory, mathematical and statistical. Results. The most intensive growth and development of sorghum plants was observed when sowing seeds with a row spacing of 45 cm and a seeding rate of 200 thousand pieces/ha. In particular, the duration of the growing season under such conditions was the smallest: 108 days for the ‘Dniprovskyi 39’ variety and 106 days for the ‘Vinets’ variety. At the same time, the indicators of field seeds germination, plant height and stem diameter were maximum in the experiment: ‘Dniprovskyi 39’ – 88.7%, 137.3 cm and 1.7 cm, ‘Vinets’ – 86.9%, 121.8 cm and 1.6 cm, respectively. It was found that an increase in seeding rate reduced indicators of productive tillering, leaf area and weight per plant. The most intense tillering of sorghum plants was observed at a seeding rate of 150 and 200 thousand pieces/ha for all the studied variants of the row spacing: on average, up to two panicles well filled with grain per plant, depending on the varietal characte­ristics. At the rate of 250 thousand pieces/ha, tillering of plants in both varieties was somewhat weaker – 1.0–1.1 panicles per plant. The largest indicators of leaf surface area and weight of one plant were with a row spacing of 45 cm: 1528–2320 cm2 and 169.2–185.6 g in the variety ‘Dniprovskyi 39’ and 1476–2180 cm2 and 143.1–162.3 g in the variety ‘Vinets’ depending on planting density. Reduction of row spacing up to 15 cm and its increase up to 70 cm led to a decrease in the main parameters of plant growth and development. Conclusions. Sorghum plants developed better when sown with a row spacing of 45 cm and a seeding rate of 200 thousand pieces/ha, which were recommended for growing crops in the conditions of the Right-Bank Forest-Steppe of Ukraine.

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. Key words: sunflower, hybrid, Rostmoment, plant height, basket diameter, oil content, yield, weight of 1000 seeds, oil yield.

The research was conducted on the structure and characteristics of the growth of shoots of the genus Viburnum L. There are significant differences in the structure and dynamics of growth within the genus, so the determination of the structural features of the shoots of species of the genus Viburnum is relevant. The research of the dynamics of shoot growth was carried out according to the method of A.A. Molchanov and V.V. Smirnov (1967). The species studied by us belong to three sections of the genus Viburnum; the peculiarities of buds structure generally determine the structure of the shoots in the species of each section. It was found that the type of each of the three sections of the genus is characterized by a special structure of the shoots. It has been studied the rhythm of growth and development of native and introduced species of the genus Viburnum L. The terms of shoots growth of the species of the genus were analyzed, and the length of the annual growth of shoots was determined. Phenological date of the beginning and end of shoot growth was established. It was revealed that the onset of individual phenophases quite clearly correlates with the sum of effective temperatures above 5 ° C. The species of the genus Viburnum are characterized by the following types of shoots: tillering, stem, generative. Intensive growth of shoots of all studied species occurs in May - mid-June. In the species of the section Lantana, there are 2 peaks of shoot growth - May and mid-July. According to the duration of growth of shoots, viburnum can be divided into two groups: 1) with a short period of growth (65 - 75 days): V.opulus L., V.sargentii Koehne, V.prunifolium L., V.rufidulum Raf., V.lentago L; 2) with a long period of growth (100 or more days): V.lantana L., V.carlesii Hemsl., V.veitchii C.H. Wright, V.rhytidophyllum Hemsl., V.buddleifolium C.H. Wright, V.burejaeticum Rgl. et Herd. The data obtained demonstrated that the greatest annual growth of all Viburnum species was recorded at the age of 4-7 years. A decrease in the annual growth of axial shoots states the need for works on preliminary rejuvenation of the bush.

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.

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.

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%.

In order to maximize the potential of productivity of spring barley varieties, it is important to optimize the conditions for plant growth and development, which are, first of all, provided by the latest intensive agricultural technologies, which provide for the correct placement of crops in crop rotation after the respective precursors; optimal supply of plants with nutrients, taking into account their content in the soil; fractional application of nitrogen fertilizers during the growing season by phases of growth and stages of organogenesis; the use of retardants, integrated protection of plants against weeds, pests, diseases, timely and quality implementation of all agrotechnical measures. Research to study the effectiveness of different terms of spring barley sowing and doses of nitrogen fertilizers were conducted during 2018 - 2019 in the conditions of the research field of VSAU v. Agronomichne of Vinnytsia region on gray ashed soils. Weather conditions during the years of the research differed from the average long-term data with high temperature conditions and low rainfall, and accordingly the most favorable year for the growth and development of spring barley was 2018. It is shown the 2-years investigation results on study the effect of sowing dates and nitrogen fertilizations on productivity elements and quality indexes of spring barley grain under conditions of Right-Bank Forest-Steppe on gray forest soils. Accordingly, the highest levels of harvest of barley cultivars at different sowing dates were obtained under conditions of 2018. t should also be noted that the delay of sowing by 6 days in the years of research leads to a decrease in the yield level on average for all varieties by 0,42 – 0,64 t / ha, and a delay of 14 days leads to a decrease by 1,37 – 1,80 t / ha. The use of nitrogen fertilizers leads to an increase in the yield level of both cultivated varieties, and the highest crop yields of the Svarog variety were obtained in the experiment where the background + N60 was applied in the foliar fertilization (4,87 t / ha), and the lowest respectively in the control variant 3,16 t /ha, in the Armax variety a similar situation is observed, however, with lower indicators respectively 4,54 and 3,06 t / ha. The lowest values of protein content in the grain were obtained in the control variant where only N17 P17 K17 was applied to rows when sowing, and the use of nitrogen fertilization leads to an increase in this indicator and the highest values obtained in the variant of experiment 4, where Background (N17 P17 K17) + N60 in the foliar fertilization on the feeding phase of the tube exit. Key words: spring barley, nitrogen fertilizers, elements of the crop structure, yield, quality of production.
