The purpose of the research was to study the effect of planting time on the formation of productivity of Hungarian sainfoin when grown for green forage. Methods are field, laboratory, statistical, correlation and regression relationships. Research results. It is established that under uneven humidity and high temperature regime in the year of sowing, Hungarian sainfoin formed two yields under spring planting date and one yield under summer planting date. In the second and third years of growth, no significant effect of the planting date on the stages of organogenesis of Hungarian sainfoin was found, where the maturity of the herbage was reached simultaneously. Productivity of Hungarian sainfoin was only conditioned by hydrothermal conditions, where the yield of green mass averaged 45.9—49.6 t/ha with crude protein content of 1.58—1.73 t/ha. At the same time, the highest dry matter yield of 10.25 t/ha and crude protein of 1.73 t/ha was provided by agrophytocenosis when sown on April 12. The productivity index of Hungarian sainfoin in the first year of life was determined, where the highest indicator was obtained during the early spring sowing period (29.04) – 7.85 kg/ha of dry matter per 1 hour of light day, whereas for the recommended summer sowing period was 1.13 kg/ha, or 6.9 times lower. The correlation equation between dry matter output, duration of daylight and the sum of precipitation from full shoots to the beginning of flowering in the first year of life is described. It is found that with increase of precipitation by 1 mm the dry matter output increases by 1.53 % and there is a tendency increase with increasing the length of daylight by 1 minute. Conclusions. It has been established that on gray forest soils of the right-bank Forest-Steppe, over two years of intensive use of the grass stand, regardless of hydrothermal conditions, Hungarian saifoin provided a stable forage productivity when sown in spring. Thus, dry matter yield was 9.38—10.25 t/ha with crude protein content of 1.58—1.73 t/ha. In particular, as for summer planting date, July 20 appeared to be the most effective planting date, which provided dry matter yield of 9.78 t/ha with crude protein content of 1.61 t/ha.

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 evaluate a promising selection sample of the Psathyrostachys juncea (Fisch.) Nevski for its adaptability to the agro-climatic conditions of the Right-Bank Forest-Steppe and on its basis to create a highly productive multipurpose variety. Methods. System analysis, field, laboratory, comparative calculation. Results. It has been established that Psathyrostachys juncea acquires optimal hay ripeness in the end of the first–at the beginning of the second decade of May, which is 12-13 days earlier in comparison with awnless bromegrass and crested wheat grass. The forage productivity of the green mass of the Psathyrostachys juncea for two mowings ranged from 3.31 kg/m2 in 2018 to 4.90 kg/m2 in 2017 and on average over the years of research was at the level of 4.15 kg/m2, or 41.5 tons/ha, while the yield of dry matter averaged 1.40 kg/m2. It is proved that the forage productivity of the Psathyrostachys juncea for the three years of use primarily depended on meteorological conditions during crop formation. The content of nutrients during the years of research was: crude protein – 14.84, fat – 2.36, fiber – 21.89 and ash – 7.46%, which meets the requirements of highly nutritious feed, especially for beef cattle farming. Conclusions. Psathyrostachys juncea (Fisch.) Nevski enters into the phase of mowing ripeness in conditions of the Right-Bank Forest-Steppe 12-13 days earlier in comparison with other studied perennial grasses. The dry matter yield averages 1.40 kg/m2 with a deviation over the years from 1.20 to 1.65 kg/m2. The value of forage productivity of this species is strongly influenced by meteorological conditions during crop formation. The content of nutrients over the years of the research was: crude protein –14.84, fat – 2.36, fiber – 21.89 and ash – 7.46%. According to the results of the research, the Askanijskyi cultivar of the Psathyrostachys juncea (Fisch.) Nevski variety was submitted for the qualification examination in the system of the state variety testing (application №19658001 dated 21.10.2019).

Purpose. To study the drought resistance of plants of English roses varieties. Methods. Field, anatomical, biometric. The drought resistance of plants in the field was assessed according to S. S. Pyatnitsky 6-point scale (1961). The number of stomata per unit area of the leaf blade was determined using a JSM-6700F scanning electron microscope (JEOL, Tokyo, Japan).  Results. The drought resistance of plants of English rose varieties was investigated both in the field and laboratory conditions. According to visual observations, during periods with a low level of moisture supply, leaf turgor did not decrease; therefore, the field drought resistance of all varieties was estimated at 5 points. According to the parameters of stomatal density per unit of leaf area, varieties that have the maximum and minimum values of this indicator were identified. Conclusions. It was found that all studied varieties of English roses from the collection of the State Dendrological Park “Alexandria” of the National Academy of Sciences of Ukraine are quite drought-resistant in the field. But they differed significantly in the density of stomata per unit area. The largest average number of stomata per 0.5 mm2 (163.67±7.93 pcs.) was recorded in the variety ‘Alan Titchmarsh’, the lowest (47.67±1.94) – in ‘Charles Austin’. Comparison of data on leaf morphology of English roses and stomata density showed that varieties with smaller leaf sizes (‘Cottage Rose’, ‘Fisherman Friend’, ‘Noble Antony’, ‘Crocus Rose’) have a greater number of stomata per unit area, which indicates their high drought resistance. The data obtained from field and laboratory studies will be taken into account in the formation of recommendations on the use of roses for landscaping urban areas, where plants may find themselves in more extreme conditions than in an arboretum.

The article is devoted to the current problem of providing rations with a source of protein with a high biological value. Such a source is suggested to be white lupine and products of its processing. Since, white lupine exceeds the protein content of peas, vetch and other legumes by more than 10%. And the significant content of fat in its composition allows, when using it, to reduce or completely abandon the use of sunflower oil in the diet. The use of white lupine allowed the experimental primates to use the food efficiently. The lowest costs were observed in the 3-test group. Energy costs were lower by 48.80%, crude protein by 47.22% and digestible protein by 51.3%. In the 2-experimental group, the costs of metabolic energy, crude protein and digestible protein were lower by 25.00%, 26.38% and 39.20, respectively. Thus, the inclusion of white lupine in the structure of the diet helps to improve the nutritional value of rations, to reduce the cost of nutrients and feed, improving the economic indicators of the maintenance of primates.

Purpose. To reveal drought resistance of hybrid tea rose varieties of garden group in field and laboratory conditions. Methods. Field, biometric, laboratory, statistical. The drought resistance of plants in the field was assessed according to S. S. Pyatnitsky 6-point scale (1961); experiments in the laboratory were to determine the water hol­ding capacity of leaves, their water deficiency, the ability to restore turgor, hydration of tissues according to the unified method of the Institute of Horticulture NAAS (Kytaiev et al., 1998, 2009). Results. According to visual observations in periods with low moisture supply, leaf turgor did not decrease, so in the field, drought resistance of hybrid tea roses was estimated at 5 points on a 6-point scale. In the laboratory, water deficiency in the leaves was calculated (as a percentage of the total water content in the state of full saturation). According to the indicators of the water-holding capacity of leaf tissues, varieties with the level of moisture loss in the exposure after 12 hours from the lowest to the highest, were selected. Conclusions. All varieties of hybrid tea roses from the collection of M. M. Gryshko NBG of NAS of Ukraine, included in the experiment, in field conditions were rather drought-resistant. According to the indicators of drought resistance of leaves from 44 model varieties, 9 with low (up to 22.30%), 5 with medium (up to 24.37%), 30 with high and very high level of moisture loss were identified (27.23–46.47%). Analysis of the research results shows that the physiological processes associated with water loss are a variety-specific, genetically inherited trait. Varieties of hybrid tea roses of diffe­rent geographical origin, which showed the criterion of drought resistance from medium to highest, can be recommended for cultivation in the Right-Bank Forest-Steppe of Ukraine.

The article presents the results of studies of the effect of seeding rates and row spacing on the forage productivity of different alfalfa ecotypes when mowing grass in the flowering stage. In the soil-climatic conditions of the right bank forest-steppe irrespective of the effect of abiotic and biotic factors during the growing season, high adaptability of alfalfa of the southern ecotype of the Angelica variety was established, which formed a stable crop of green mass at the optimal seeding rate (8,0 million/ha) and width 12,5 cm. For an average of two years of grass use, the varieties of alfalfa Rosana and Angelica provided a yield of green mass of 62,96-64,02 t/ha, which was 11,1-14,9% higher than for sowing with the norm of sowing 4,0 million/ha, and 6,3-7,1% with row spacing half (25,0 cm). It was found that in two years of use of alfalfa Angelica variety had higher dry matter content, compared with the variety of Rosana and were respectively 23,05 and 22,98%. There was a gradual decrease in the dry matter content with a thickening of the herbage in the Rosana variety from 23,32 to 22,72% and from the Angelica variety from 23,31 to 22,84%. As the row spacing increased from 12,5 to 25,0 cm, the solids content increased by 0,28-0,62%, or 22,74-22,84 and 23,12-23,36%. The crude protein content in the dry matter of alfalfa plants of both varieties differed by slopes and years of herb use. The highest content of crude protein was obtained in the dry matter for sowing with a row spacing of 12,5 cm, which averaged 21,10% in the Rosana variety and 20,23% in the Angelica variety or increased by 0,79-0,87%, compared to the row spacing of 25,0 cm. Thus, irrespective of the hydrothermal conditions during the growing season of the studied varieties of alfalfa sowing Rosana and Angelika, the average yield of dry matter at the level of 13,64-13,93 and 2,76-2,88 t/ha of crude protein at the width of row 12,5 cm. Key words: alfalfa, variety, flowering start, crude protein, dry matter, yield, green mass.
