The results of researches on studying of influence of mulching of soil on formation of a crop of plants of a zucchini in the conditions of the Right - bank Forest - steppe are resulted. The dependence of the phases of growth and development of zucchini plants, the dynamics of fruiting and yield in general on the type of mulching material was revealed. The use of synthetic mulching materials helped to reduce the interphase periods, increase yields and the percentage of early and late harvest. Mulching materials of organic origin extended the interphase periods. Thus, the shorter germination period - the beginning of fruit formation was by mulching the soil with perforated black polyethylene film and black agrofiber, which is 5-8 days shorter than the control, respectively. The longest harvest of zucchini was carried out on options for mulching the soil with black agrofiber and perforated black polyethylene film, depending on the variety, the duration of fruiting ranged from 67-85 days with the value of this indicator in the control 72-77 days. The highest yield was obtained by mulching the soil with perforated black polyethylene film, where the increase relative to the control was 10.9 - 28.0 t / ha, respectively. The highest percentage of harvested early products was provided by options for mulching the soil with black agrofiber and perforated black polyethylene film at the level of 6.6-8.3% in 2016 (control - 0.8-4.1%) and 3.2-5, 0% in 2018, while in the control versions the collection started a decade later. The most intensive fruiting of zucchini was observed from the first decade of July to the first decade of August for all years of research.

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.

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. 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.

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’.

In Ukraine, grain sorghum is considered a valuable crop, as it is used in the food industry, in fodder production and in the energy industry, and control of the number of weeds in crops is extremely important. The aim of the research was to establish the influence of methods for controlling the number of weeds on the growth and development of grain sorghum plants in the conditions of the Right-Bank Forest-Steppe of Ukraine. Methods. Field — to study the biological, ecological features of growth and devel¬opment of productivity and quality of culture (ob¬servation, obtaining correlations), laboratory — to identify the relationship between plant and the environment (analysis of plants and soil); generalization — to establish the general properties and characteristics of objects; mathematical and statistical — to process experimental data to increase the validity of conclusions. Results. Weed infestation and the use of various methods of controlling the number of weeds influenced the growth and development of plants, namely: in the variant with high infestation, the growing season was the longest – 121–124 days, the plant height was 39–77 cm in the Dnіprovskiy 39 variety, and 72 cm in the Vіnets variety. cm, the number of productive stems was 12.6 pcs/m2 in varieties Dnіprovsky 39 and 12.3 pcs/m2 in varieties Vіnets, leaf surface area 1 plant and plant weight had low indicators as in variety Dnіprovsky 39 (1053.2 cm2 and 973 g/m2) and in varieties Vіnets (1017.3 cm2 and 912 g/m2), other methods of controlling the number of weeds were observed significantly better growth and development of grain sorghum plants. Conclusions. In the Right-Bank Forest-Steppe of Ukraine, the quantitative and species composition of weeds in crops of grain sorghum was studied. In the crops of grain sorghum, mainly monocotyledonous and dicotyledonous types of weeds prevailed. Their average number was 101.0 pcs/m2, their air-dry weight was 158 g/m2. It was found that the high efficiency of weed control was observed in the variant with manual weeding by almost 97 %, in the variant with the mechanical and chemical methods, the efficiency was from 76 to 79 %. On the variant with biological weediness (control), the amount of weeds increased by almost 10 %.
