In the Forest-Steppe Zone of Ukraine, a study was carried out to establish the effect of mineral fertilizers and drip irrigation on the yield of dry raw material. It was found that irrigation significantly increases productivity of althaea, by eliminating the deficit of soil moisture in critical periods of growth and development. The yield increase caused by the use of drip irrigation in the first year of vegetation of the crop was 1.27–1.98 t/ha for dry grass, for leaves — 0.69–1.17 t/ha, for roots 0.22–0.39 t/ha. For the second growing season, the yield increase was: 1.52–4.7 t/ha for grass, 0.46–1.35 t/ha for leaves and 1.5–2.76 t/ha for roots. It was also found that increase of the mineral fertilizers main application dose caused increase of the yield. The highest yield of dry raw material of the culture was obtained in both the first and second years of the growing season with the introduction of N180P180K180. With the application of mineral fertilizer at a dose of N180P180K180 under conditions of drip irrigation, the yield of dried althaea grass was 8.09 t/ha, leaves — 3.88 t/ha, roots — 3.08 t/ha, which exceeded the option without fertilizers and without irrigation by 4.08 t/ha for grass, 2.04 t/ha for leaves, 1.44 t/ha for roots. The highest yield was obtained in the second year of vegetation using the variant with the application of the highest dose of mineral fertilizers under drip irrigation, where the yield of dry grass was 15.78 t/ha, leaves — 4.42 t/ha, roots — 6.24 t/ha. On the plantation of the second year of vegetation in the variant without irrigation and without fertilizers, the yield of raw materials was the lowest. It was 6.85 t/ha for grass, 1.88 t/ha for leaves and 2.12 t/ha for roots.

The purpose of the work is to study the effect and aftereffect of various types and rates of fertilizers on the change in the main fertility indicators of gray forest soil, as well as the productivity of the crop rotation link. The experiments were carried out in the grain-row unit (spring wheat - corn - spring wheat - peas) of a nine-field grain-herb-row crop rotation. The scheme of the experiment provided for the study of the following options: the calculated doses of mineral fertilizers for the formation of 4 t/ha of spring wheat grain, 40 t/ha of green mass of corn, 3 t/ha of pea grain, thermally treated granulated chicken manure in doses 1, 2, 3 t/ha, bedding manure in a dose equivalent to 3 t/ha of granulated droppings, buckwheat stubble green manure sown after harvesting winter rye. Under the influence of 1-2-3 t/ha of granulated chicken manure, the content of nitrogen (Nг) in the soil increased, compared with the control, by 73.1-81.1-112.0%, respectively, phosphorus (P2O5) - by 69.3- 79.8-91.3%, potassium (K2O) - by 90.3-140-188%; in the first year of aftereffect, Nг increased by 42.6-50.5-58.4%, P2O5- by 28.6-39.3-52.1%, K2O - by 56.1-84.8-170, 7%; in the second year of aftereffect Nг - by 13.1-21.3-44.0%, P2O5- by 40.1-51.2-74.4%, K2O - by 63.3-124.1-133.1 %. When manure was applied (42 t/ha), the amount of Nг, P2O5, K2O decreased, compared to 3 t/ha of granulated chicken manure, in the year of action, respectively, by 43.4, 19.0 and 42.2%, in the first year of aftereffect - by 16.6, 22.1, 48.1%. In the second year of the aftereffect, the values of these indicators when using manure and 3 t/ha of granulated chicken manure were equivalent. In the variant with the incorporation of buckwheat green manure, the content of mobile forms of macronutrients varied similarly to manure. Under the influence of 1, 2 and 3 t/ha of granulated chicken manure, the productivity of the crop rotation link increased, compared with the control, by 78.5, 104.3, 122.6%, respectively. The effect from the action and three years of aftereffect of 42 t/ha of manure was below the level of 3 t/ha of of granulated chicken manure by 12% (productivity growth 110.6%), buckwheat green manure - at the level of 1 t/ha of granulated chicken manure (productivity growth 80.6%) ...

Relevance and methods. For the production of chicory seeds, care must be taken not only to obtain a high-grade source material, i.e. varietal seeds and masterbatch root crops, but also to store the resulting root crops in winter with minimal losses. The main requirement for growing mother chicory root crops is the placement of crops on fertile soils that are clean of weeds. Installed. That on podzolized loams the best dose of mineral fertilizers for this crop is N45P120K60, where an increased dose of superphosphate increases the yield and rootability of Queen cells, increases seed productivity for the second year. Materials and methods. The purpose of this work is to analyze the safety of root crops of chicory root and the degree of their damage by root rot during winter storage in plastic bags in burts. The purpose of the study is to identify the best way to store the mother chicory root crops and the effect of reproduction on the rootability of root crops in winter. Questions of storage of the mother material of root chicory were studied in the laboratory of selection and seed production on the example of the Petrovsky variety in 2017-2019. The material for research was the families of chicory of the Petrovsky variety in the control and elite nursery. Results. The obtained data show that when evaluating and selecting families for the purpose of obtaining highly productive seed material, the safety of root crops in long-term winter storage should be taken into account. If its values are low, the entire family should be completely excluded from the process of primary seed production. In selection and seed-growing work, a mandatory component of the assessment should be the safety of root crops during long-term winter storage.

Echinops sphaerocephalus – многолетнее растение семейства астровых, может применяться в качестве нектароносного, лекарственного, противоэрозионного и декоративного растения. Регулирование минерального питания способствует повышению продуктивности растений. Внесение минеральных удобрений является одним из действенных способов увеличения продуктивности растений. Цель исследований – изучить влияние разных норм минеральных удобрений на медовую продуктивность мордовника шароголового в интересах пчеловодства. Медовую продуктивность определяли по содержанию сахаров в нектаре цветков методом смывания и последующим анализом по Гагендорн-Иенсена. Содержание сахаров пересчитывали на гектар и умножали на коэффициент 1,25. Математическую обработку результатов проводили методом дисперсионного анализа с использованием компьютерной программы Excel 2010. Одним из показателей развития растительного сообщества является густота стояния растений. Влияние минеральных удобрений должно быть направлено на формирование как можно большего числа генеративных побегов. Мордовник шароголовый начинает их формировать на второй год жизни. Исследования показывают, что данный показатель в этот период в десятки раз меньше по сравнению с третьим годом жизни. На третий-четвертый годы жизни (2017-2018 гг.) количество генеративных побегов наибольшее по сравнению с другими годами наблюдений. Ежегодная подкормка азотными удобрениями приводит к существенному возрастанию этого показателя. Мордовник шароголовый отзывчив на внесение азотных удобрений. Наблюдается прямая положительная корреляция между количеством цветков на единице площади и медовой продуктивностью посевов: коэффициент корреляции 0,993, коэффициент детерминации 0,988. Главные выводы: наилучшие показатели получены при внесении N30P80K80 в год посева и N90 в ежегодную подкормку весной. По количеству генеративных побегов этот вариант превосходит контроль на 88,9%, а по количеству цветков и медовой продуктивности – в 3 раза. В то же время в первые три года возможно внесение N60 и только на четвертый год необходимо увеличить дозу до N90. Echinops sphaerocephalus is a perennial plant of the Asteraceae family. It can be used as a nectaric, medicinal, anti-erosion and decorative plant. The regulation of mineral nutrition helps to increase the productivity of plants. Applying mineral fertilizers is one of the most effective ways to increase plant productivity. The purpose of the research is to study the effect of different norms of mineral fertilizers on the honey productivity of the Echinops sphaerocephalus in the interests of beekeeping. Honey productivity was determined by the sugar content in the nectar of flowers by the method of rinsing and subsequent analysis Hagedorn of St. Petersburg. The sugar content was recalculated per hectare and multiplied by a coefficient of 1.25. Mathematical processing of the results was performed using the method of variance analysis using the Excel 2010 computer program. One of the indicators of the development of the plant community is the density of standing plants. The influence of mineral fertilizers should be directed to the formation of as many generative shoots as possible. Echinops cue ball begins to form in the second year of life. Research shows that this indicator in this period is ten times less than in the third year of life. In the third and fourth years of life (2017-2018), the number of generative shoots is the highest compared to other years of observation. Annual fertilizing with nitrogen fertilizers leads to a significant increase in this indicator. Echinops sphaerocephalus is responsive to the application of nitrogen fertilizers. There is a direct positive correlation between the number of flowers per unit area and the honey productivity of crops, the correlation coefficient is 0.993, the determination coefficient is 0.988. Main conclusions: the best results were obtained when adding N30P80K80 in the year of sowing and N90 in the annual feeding in the spring. By the number of generative shoots, this variant exceeds the control by 88.9 %, and by the number of flowers and honey productivity – by 3 times. At the same time, N60 can be added in the first three years, and only in the fourth year it is necessary to increase the dose to N90.
