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 problem of climate change and global warming both in whole and in particular has become one of the most serious and urgent directions of scientific and technical activity at the present stage. The future food security of Ukraine depends on the effectiveness of adaptation of agriculture to new conditions dictated by the global anthropogenic warming. In order to evaluate possible impact of climate change in Ukraine on agroclimatic indicators the scenario A1B - "moderate" was used providing a balance between all energy sources. Researches of sunflower harvest formation are carried out using a dynamic model of agricultural crops productivity. For a comparative analysis of scenary meteorological variables with previous data the period from 1986 to 2005 is taken from agroclimatic directory of Ukraine. It serves as a base when performing calculations. According to calculations of A1B climate change scenario, periods of sowing and subsequent phases of development will occur earlier than at present, which will lead to reduction of the whole vegetation period at most parts of the area under study. As a result of comparative analysis of temperature and precipitation regime it was found that, subject to implementation of the climate change scenario under study, expected weather conditions will be more favourable for cultivation of sun-flower in the Western and Central forest-steppe, as well as at the Right-Bank Ukraine and in the Donetsk sub-zone of Northern steppe of Ukraine.

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%.

The Impact

The article presents findings of the influence of different levels of mineral nutrition on plant growth and development, the impact of fertilizers on the botanical composition, on the productivity and forage benefits of cereal-bean agrocenoses in the forest-steppe zone of the Baikal region. The objects of research were mixed crops of oats with peas and millet with vetch, peas, and Austrian winter pea. Legumes are the main source of protein increase in feed. In the field, the most widespread, among legumes, were vetch, sowing peas, field peas (Austrian winter pea). As a result of phenological observations, it was found that the growth and development of plants depended on the biological characteristics of crops, weather conditions and directly on the mineral nutrition level. The millet reacted most effectively to the application of mineral fertilizers, starting from the exit phase into the tube. The introduction of mineral fertilizers in pre-sowing tillage contributed to an increase in the proportion of legume components in the total green mass yield and a decrease in cereals. The highest competition in agrocenoses of millet with legume components was vetch, its share in the mixture increased, compared to the unfertilized background, by 6 and 14.5%, depending on the background of fertilizers. It was found that, compared with the unfertilized background, mineral fertilizers increased the yield of green mass from 1.5 to 4.9 tons per hectare, the collection of dry matter from 0.4 to 2.0 tons per hectare and the collection of feed units from 0.3 to 1.3 tons per hectare. Digestible protein content in 1 unit increased with the introduction of nitrogen fertilizer (N45), depending on the type of components in the mixture, from 3.2 to 6.6 g, and with the introduction of complex mineral fertilizer (N45P30K30) from 2.5 to 9.6 g. All are millet-bean mixtures at all levels of mineral nutrition comply with zootechnical standards.

The article considers and proves that the use of biological products affects the formation of highly productive crops and promotes the production of products with a high content of biologically active substances. Studies have shown a positive effect of biological products on the growth and development and yield of beetroot varieties Delicatessen and Red Ball. Studies have been conducted to study the technological aspects of growing vegetables, in particular with the use of biological products, taking into account the environmental impact of both growth processes and quantitative and qualitative indicators. Features of various biological products and their efficiency are analyzed. A comparative analysis of the use of biologicals, which allowed to comprehensively assess the impact of elements of cultivation technology on phenological, biometric, indicators, yield and quality of table beet products, development and improvement of elements of technology for their cultivation in the forest-steppe of Ukraine. This involves the use of highly productive varieties, the use of various effective biological products, is relevant for the spread and cultivation of table beets in the forest-steppe of Ukraine. Phenological observations of canteen beet plants showed that they developed differently and reacted differently in the phases of growth and development, depending on the introduced biological products. The technical ripeness phase began on days 121–129 and was longer than in the control. With the introduction of Solutin and Chlorella – 128–129 days, and in short - with the introduction of biological products Helprost vegetable, Helprost vegetable + Phytohelp, Solutin + Phytohelp – 121–125 days. It was proved that table beet plants differed in height, number of leaves, leaf blade area and their total area per hectare, which compared to the control were from the use of a tank mixture of biological products Helprost vegetable + Phytohelp – 28.3–28.7 thousand m2/ha, which is significantly higher than the control by 13.6–14.8 thousand m2/ha. The area of leaves was slightly lower as a result of the use of other drugs and mixtures – 21.8–22.6 thousand m2/ha. The use of a mixture of drugs Helprost vegetable + Phytohelp contributed to an increase in the mass of the root of table beets by 255–350 g, which is significantly higher than the control by 9–10 g. A positive effect on the yield of beetroot was shown by the vegetable Helprost preparation, as well as a mixture of vegetable Helprost + Phytohelp preparations, the use of which provided a yield of 52.4–63.8 t/ha.
