With the development of modern floral business, Callistephus chinensis (L.) Nees is among the top three of the most popular crops, yielding only chrysanthemum and calendula in commercial cultivation. This is one of the most widespread seasonal decorative annual flower crops, which is beautifully cultivated in open ground, pots and bouquet flowers. The researches presented in the article were conducted in order to determine the influence of weather conditions during the growing season of C. chinensis on the research sites of the educational scientific-production complex of the Sumy National Agrarian University (Northeast Forest-steppe of Ukraine) and the effectiveness of the application of various norms of complex mineral fertilizers, introduced at the planting of seedlings into open ground, on the processes of growth, flowering and other qualitative characteristics of the five varieties. During the growing season, the climatic conditions of the region of conducting research, variety characteristics, and also the variability of the parameters of height, number and diameter of C. chinensis inflorescences of the varieties 'Olenka', 'Leleka', 'Litnia Nich', 'Tsarivna' and 'Yabluneva' were influenced by variability mode of mineral nutrition. Weather conditions of vegetation have an impact on the number and size of inflorescences. According to research results, it has been established that there is a certain relationship between the weather conditions of the year and the number of inflorescences. So, the increase in the amount of precipitation during the growing season contributes to the development of the vegetative mass, but also negatively affects the formation of the number of inflorescences C. chinensis. For most varieties, the optimal conditions for the development of the generative sphere were the normal conditions for moisture of the year, and for the 'Litnia Nich' variety it was dry. The greatest increase in height when fertilizing compared to control was observed by the variety 'Tsarivna' (15.9 %), the smallest - by the variety 'Olenka' (2.0 %). The formation of inflorescences of greater diameter by the plants of the varieties 'Olenka', 'Litnia Nich' and 'Tsarivna' was observed in 2016, and by the 'Leleka' and 'Yabluneva' varieties in 2017. For most varieties in 2015, the diameter of inflorescences was the smallest. Studies have shown that weather conditions do not have a significant effect on the diameter of inflorescence, unlike mineral nutrition. The diameter of the inflorescences was the highest in comparison with the control by the variety 'Olenka' (18.3%), the smallest - by the variety 'Tsarivna' (1.1 %). The most valuable morphological and decorative features of C. chinensis plants of the five varieties under study were formed according to the norms of complex mineral fertilizers (nitroamofoska) 6.0 g/m2. The further increase of norm was not appropriate.

Drought Resistant

The cultivation expediency of more drought-resistant crops, in particular sorghum, millet, false flax, safflower and others, instead of sunflower in the area of the Southern Steppe of Ukraine is substantiated. This is, first of all, required by climate change both in Ukraine and in the world. Since 2004, researches of field crops were carried out in the conditions of the Educational and Scientific Practical Center of the Mykolaiv National Agrarian University. Soil phase is the southern chernozem with humus content in the 0–30 cm soil layer which consist of 2.96–3.21 %, with medium and high level of availability of mobile phosphorus and potassium and low – mobile nitrogen. Experiments with soriz (Oksamyt hybrid) were conducted during 2004–2006, millet (Tavriiske, Kostantynivske, Skhidnevarieties) in 2008–2010, grain sorghum (Stepovyi 5 hybrid) in 2014–2016, safflower dye (Lahidnyi variety) in 2017–2019. The years of research differed significantly in temperature and even more in the amount of precipitation before sowing and during the growing season of crops. However, the weather conditions were typical of the Southern Steppe zone of Ukraine. It is established that all studied drought-resistant crops respond positively to nutrition optimization – the level of yield and quality of grain or seeds increases. It was found that the soriz productivity depending on the application of fertilizers and sowing dates increased by 37.6–39.2 %, millet –by 33.3–41.6 %, grain sorghum depending on the background of nutrition and growing conditions – by 8.2–33.2 %, dye safflower – by 11.1–64.6 %. It was determined that the optimization of nutrition of cultivated crops allows to increase their resistance to adverse conditions and productivity in the case of application of low doses of the mineral fertilizers before sowing, pre-sowing treatment of seeds, and growth-regulating chemical application of plants on the main stages of the growing season. Key words: drought-resistant plants, climatic conditions, nutrition optimization, yield, crop quality, varieties, sowing dates.

The experimental studies were carried out on the fields of the Sumy NAU Training Research and Production Complex (TRPC) during 2016–2018.The soil of the experimental plot is typical deep-medium humus, large-dusty and medium-loam black soil on forest trees. The subject of the research was a white mustard variety of Oslava created at the Institute of Feed and Agriculture of the Podillya NAASU, entered in the Register of varieties suitable for cultivation in Ukraine in 2010. The aim of the research is to optimize the nutrition of the white mustard variety of Oslava through the complex application of mineral fertilizers and foliar fertilization under the conditions of the northeastern forest-steppe of Ukraine. The analysis of weather conditions, in particular the hydrothermal coefficient of Selyaninov (HTC), established that 2016 season was wet (HTC = 1.60), 2017 and 2018 were dry (HTC = 0.59 and 0.46). During the research, the cultivation technology was generally accepted in the experimental area, except for the elements studied. The results of the three-year study on the influence of foliar fertilizing under different mineral nutrition backgrounds on the yield of the white mustard variety Oslava are presented. It was found that the application of mineral fertilizers and complex fertilizers for the foliar feeding had a positive effect on the morphometric parameters of the white mustard, in particular, increased the plant height and the number of branches of the first order. The use of mineral fertilizers at the rate of N30P30K30 provided an increase in the yield by 0.34 t/ha, N60P60K60 – by 0.55 t/ha, N90P90K90 – by 0.61 t/ha on an average compared to the control. Therefore, for the maximum yield (2.14–2.21 t/ha) with a mass of 1000 seeds (5.39–5.54 g) of the white mustard under the conditions of the Northeastern Forest-Steppe of Ukraine, foliar fertilizing of Vuxal boron (3.0 l/ha) + Vuxal bioaminoplant 3.0 l/ha) and Spectrum B + Mo (2.0 l/ha) + Spectrum Ascorist (3.0 l/ha) should be applied on the background of N60-90P60-90K60-90, what provided an increase in the yield compared to the control of 0.58-0.65 t/ha.

The Cost

A powerful factor in increasing the yield of feed mixtures is the use of mineral fertilizers. On average, over 4 years of research, the yield of green mass increases from 13.8 tons per hectare at the control (without fertilizers) to 27.4 tons per hectare (almost 2 times). However, the effectiveness of the use of mineral fertilizers depends on how the sunflower and annual herbs are placed in space. Thus, on all backgrounds of mineral nutrition, the highest yield of green mass was obtained by sowing sunflower and annual herbs in separate strips with strip widths of 180 cm: N85P38K46 - 28.2 tons per hectare; N99P44K54 - 32.9 tons per hectare; N113P51K61 - 34.2 tons per hectare. In the same conditions, both narrowing the bands to 90 cm and expanding to 360 cm reduce the yield of the object of study. Mineral fertilizers also have a great influence on the gross yield of raw fat (an increase of 2.8 times), feed units - from 2,562 to 3,904, crude protein - 1.9 times, exchange energy - 2.4 times. As a result, the payback of each ruble of the cost of mineral fertilizers provides for the production of 1.5 rubles, and the bioenergy coefficient increases to 4.4, versus 2.2 for mixed sowing of sunflower and annual herbs.

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 results of research conducted in 2015-2019 in the forest-steppe agroclimatic zone to identify the dependence of economically valuable traits of soybean varieties on the meteorological conditions of the Ryazan region are presented. The soil of the experimental site is dark gray forest, heavy loamy in granulometric composition. Reaction of the soil solution-phsol. - 5,2; humus content 5,8 %. Mobile phosphorus content – 191.4 mg / kg of soil; exchange potassium content-108.5 mg / kg of soil; nitrate nitrogen-8.4 mg / kg; ammonium nitrogen-1.57 mg/kg. The object of the research were varieties of soybean breeding, FEDERAL state scientific institution "Ryazan research Institute of agriculture" - Mahewa, George, Whale, Light. The work was carried out in accordance with the methodology of the State variety testing of agricultural crops and the methodology of field experience. To characterize the climatic conditions, we used an integrated indicator – Selyaninov's hydrothermal coefficient (GTC). It was found that the duration of the growing season of early — maturing varieties depends more on the weather conditions in july, early-maturing varieties-on the conditions in august. The height of the plant is affected by weather conditions in june, and the weight of 1000 seeds – in july. The yield of soybeans largely depends on the climatic conditions during the main stages of development of the crop. The average yield over the years of the study for varieties was in the range from 1.37 to 1.79 t/ha. The highest yield was recorded in 2015 and 2016 with the GTC close to 1, the lowest yield for varieties was obtained in 2018 with the GTC=0.6. A significant relationship was found between seed yield, seed weight from the plant and the GTC of the growing season: the variation in soybean seed yield by 67% is associated with the action of the studied factors (R2=0.67).

Relevance. A study of the seasonal (phenological) phenomena and natural connections between them on the background of the relevant environmental conditions is of great scientific and practical interest. Knowledge of the dynamics of the seasonal development of woody plants helps in the selection of species and their assessment from an aesthetic and sanitary points of view, as well as in the development and implementation of measures to increase the sustainability of urban green spaces. Materials and methods. The purpose of these studies is to create a database of the dynamics of seasonal development of North American woody plants based on the results of many years of phenological monitoring (2003-2017). The 20 species and forms of North American woody introducers e of the VNIISPK arboretum genetic collection were the objects. Results. It was revealed that the growing season of woody North American plants corresponds to the climatic conditions of the forest-steppe zone of central Russia. The species with the earliest beginning of the growing season (the third decade of March) were distinguished. There were Mahonia pinnata, M. aquifolia, Betula lenta and B. lutea. On the basis of phenological calendars, phenological spectrums have been constructed. These consist of three lines (the development of leaves, shoots, flowers and fruits) with the corresponding color symbols. It has been revealed that phenospectrums vary depending on the conditions of the year. As a result, the database of 20 species and forms of North American woody plants was formed in the form of phenological spectrums against the background of registration of weather conditions in the forest-steppe zone of Russia. The database includes three options for the possible dynamics of the seasonal development of introduced North American plants. The created database allows observing, comparing, evaluating and forecasting changes in the seasonal rhythm of the studied species of introduced North American plants.

Strong growth of shoots and ripening of grape fruits do not give grounds for claiming that the variety is in accordance with the climatic conditions of a certain area. Only a well-ripe vine can withstand severe winter conditions. The purpose of the study is to determine the degree of maturation of the vine in grape varieties of Odessa breeding grown in the northern part of the Forest-steppe, and to identify among them the most prepared for wintering conditions in the area. The degree of maturation of the vine was determined during 2018–2019 in the autumn before the cover of grape plants by the method of primary fluorescence using a microscope MBS-2 with fluorescent illuminator OI-18 and by the method of N. Matuzok. Studies have shown that the degree of ripening of the grapevine depends on the weather conditions during the growing season and varietal characteristics of the plants. Weather conditions during the years of study contributed to the good maturation of the shoots of grapes of all varieties except Kometa and Zahadka. The first had a characteristic brown color of the mature bark along the entire length of the shoot. When bending the vine in its upper part of the characteristic cracking of the bark was not in the varieties Kometa, Zahadka, Yarylo and Muskat odeskyi. The highest degree of ripening of shoot tissues was noted in the lower zone of the vine in the Aromatnyi, Kardyshakh, Kishmish tayirovskij. In the middle zone of shoots, the highest degree of maturation of the felema was found in the variety Kardyshakh, and in the upper part of the shoot, in the variety Aromatnyi. The highest conditional coefficient of maturation (Kv) of the tissues of the vine in the fifth internode is defined in the varieties Aromatnyi and Kyshmysh tairovskyi (0.90), the mean in the variety Kardyshakh (0.88), and the lowest in the variety Kometa (0.56). Based on the data obtained from the results of complex studies, it was found that the varieties Aromatnyi, Kyshmysh tairovskyi and Kardyshakh are the most prepared for wintering in the northern part of the Forest-steppe.

The paper presents the results of the longterm studies (1982-1995 and 2011-2014) on the effectiveness of mineral fertilizers (NPK) on medium-textured soils of the forest-steppe zone of the Northern Trans-Urals. The studies were conducted on the experimental land-reclamation system located in the central part of the Tarmansky bog land on the second lacustrine-alluvial terrace of the Tura river. The soils have a weakly acid medium reaction 5.2-5.9, relatively low hydrolytic acidity 28.1^10.8 mg - eq. /100 g of soil, a relatively low degree of base saturation 61.7-75.5%, high content of total nitrogen 3.1-3.9% and low content of phosphorus0.09-0.14%andpotassium0.02-0.05%. As a result of the research, it was revealed that there was a lack of nutrients both at the beginning of the growing season of perennial grasses during cold spring and permanently in the second half of the growing season. Therefore, without fertilization, perennial grasses form low hay yields (1.95 t/ha in two-time mowing on average in 14 years). It was noted that over the years, the yield of grass without fertilizers does not tend to increase. Yield fluctuations over the years are mainly due to weather conditions. Systematic application of complete mineral fertilizers in dressings increases the yield of hay of perennial grasses by 2.6-3.8 times. The maximum increase of hay by 32.2 kg on average in 14 years was achieved when applying N30P60K60. The increase in the fertilizer rate from 150 to 240 kg of the primary nutrient reduced the efficiency of each kilogram of the primary nutrient by 20%, whereas the increase up to 330 kg reduced the efficiency by 34%. The need of grasses in nitrogen is satisfied by mineral fertilizers by less than a half (41.4%). Formation of an adequate second mowing is possible only with the application of fertilizers. Fertilization provides a dominant position (87- 92%) of the awnless brome from the second year of using grasses. Annual fertilizer dressings applied to perennial grasses allow to obtain high-quality hay.

We can expect to receive from 0.81 to 0.97 tons of sunflower oil seeds per hectare in the soil-climatic conditions of the forest-steppe zone of the Middle Volga region without the introduction of mineral fertilizers. As the doses of mineral fertilizers are increased, the productivity of 1 hectare of arable land is increased 2.8 times and the gross collections of oilseeds are 2.14 tons per hectare at the non highest background of mineral nutrition, against 0.86 tons per hectare in the control variant of the experiment (without fertilizers). The optimization of seeding rates of the studied culture is of great importance in the formation of highly productive agrocenoses. In the variants of supplementary supply of plants with nutrients, especially when N98P38K124 is introduced, the seeding rate of 70 thousand pieces per hectare of virgin seeds raises the yield of sunflower by 0.51 tons per hectare (a very solid increase in yield), compared with the sowing rate of 60 thousand pieces per hectare.

In modern conditions of agricultural intensification, the use of a scientifically based fertilizer system becomes extremely necessary. It is she who will allow you to get economically viable crop yields. Studies to obtain the planned yield with the introduction of increasing doses of mineral fertilizers were carried out in 2018-2020 in the forest-steppe zone of the Urals. The soil is old leached chernozem. Experiment scheme: control (without fertilization); application of mineral fertilizers to the planned yield: by 3.0 t/ha of grain N40 P75; 4.0 t/ha - N95P110; 5.0 t/ha - N150P200 and 6.0 t/ha - N185P160 kg of active ingredient. On average, over the years of research, the planned yield of spring wheat was achieved. The cost of growing spring wheat without mineral fertilizers amounted to 16850 rubles/ha. The introduction of mineral fertilizers for the planned harvests increases costs up to 34200 rubles/ha. Such high costs are explained by the use of phosphate fertilizers, whose price is twice as high as ammonium nitrate. In the structure of costs for obtaining a yield of 3.0 t/ha of grain, the share of mineral fertilizers accounts for 17 %. A further increase in the level of mineral nutrition through fertilizers increases the share of fertilizer costs up to 45 %. The profit from the sale of grain on the option with NPK of 6.0 t/ha of grain reached 27400 with a profitability of 80 %. On the control, the corresponding indicators were 5150 rubles/ha and 31 %. The optimal and economically justified is the level of mineral nutrition, providing 4.0 t/ha of spring wheat grain. A further increase in the agricultural background is associated with a risk due to the peculiarities of weather conditions in the forest-steppe zone of the Urals
