Its considerable variability is established over three years (2017–2019). The effect of the treatment agents on most microorganisms of wheat seed microbiota in Ukraine, rather than on its genera and species, is shown. It has been proven that fungicides deleted some species and did not affect the development of others. Chemicals replaced some species or genera of fungi with others or even other microorganisms. Biological seed treatment (Phytosporin-M) has caused less microbiota change than chemical treatment (Maxim 0.25 FS, Rostock, Kinto Duo). Fungicides have replaced the dominance of Alternaria spp. (2017 – 57.8%, 2018 – 63.5%) for the dominance of yeast (Rostock – 54%) and Aureobasidium pullulans (Maxim 0.25 FS – 84.2%) in 2017, bacteria (Maxim 0.25 FS – 72.3%, Rostock – 53.8%) – in 2018. A. pullulans dominated in the microbiota of winter wheat seeds in 2019. The highest amount of A. pullulans was noted for the treatment of seeds by Phytosporin-M (85.9%). The biological seed treatment reduced the amount of Nigrospora spp. and Alternaria spp. Several times (3 and 5, respectively), chemical agents did not give Nigrospora spp. germination reduced the amount of A. pullulans, Alternaria spp. in 2019. Maxim 0.25 FS, Rostock 50%, and Kinto Duo delayed seed germination and seedling development on agar medium and soil, whereas Phytosporin-M – on the contrary, promoted the growth of seedlings and significantly exceeded control. \u0000 \u0000Keywords: seed microbiota, winter wheat, seed treatment, seed-borne fungi, fungicides \u0000  \u0000 \u0000References \u0000 \u0000Adhikari, P., Khatri-Chhetri, G., Shrestha, S., & Marahatta, S.

They belong to a line Hemiptera, the family Shield bugs (Pentatomidae), and the genus Cruciferous bugs (Eurydema). The dominant species is the cabbage bug. The mustard bug dominated only in 2007, and since 2012 it has not been detected in the records. They are widespread throughout the whole territory of Ukraine. Both adult bugs and larvae damage the crops; they pierce the leaf skin or floriferous shoots with the proboscis and suck out the juice. The light spots appear at the puncture points, the tissue dies, falls out, and the irregular form holes are formed. When the seeds are damaged, the flowers and ovary fall off, and the seeds' quality deteriorates. The harmfulness of the bugs increases dramatically in dry and hot weather. We found out that the largest number of wintering bugs was concentrated in the forest belts, near which there were the crops of spring oilseeds and cabbage plants and the seeds of white cabbage. The density of wintering imagines of the cabbage bug was 1.7–4.4 specimens/m², and the density of the rape bug was 0.9–2.3 specimens/m² of the forest floor. In the first turn, the wintered bugs' imagines populated the cabbage seeds as a trap crop, and then they populated the sprouts of spring rape and mustard. The density of the cruciferous bugs on the seeds of white cabbage of Kharkivska 105 variety was 19.0-30.7 specimens per plant at the beginning of the populating of spring oilseed cabbage crops at the Educational, Research and Production Centre \"Research Field\" of Kharkiv National Agrarian University named after V.V.

We conducted our research under Bila Tserkva National Agrarian University (Ukraine) educational and production center conditions in 2017-2019. During the active growing season of corn plants (June), moisture reserves in the 0-20 cm layer of the soil decrease to the level of unsatisfactory, and the plants experience a lack of moisture. Although, as results of defining moisture stocks in 0-100 cm layer of soil show, plants begin to assimilate it in the third ten-day period of May actively, and there is a sharp transition to good moisture stocks in the first ten-day period of June and to poor ones in the second and third ten-day periods of June. Cultivation of maize hybrids with FAO over 400 in unstable moisture conditions is quite risky because plants experience a significant lack of moisture in periods of their active growth and development. We have proved that at the density of crops within 55000/ha, the highest coefficients of water consumption were observed compared to plant densities of 65000 and 75000/ha. At hybrid DO Pivikha, the difference between average values of coefficient of water consumption at densities of crops 65000 and 75000/ha, was 25.5 and 46.75 m3/t, at hybrid DO ORLIK – 14.25 and 41.0 m3/t and at hybrid DO SARMAT respectively 17.5 and 39.0 m3/t. We found that the mineral system of fertilization compared with the organic-mineral and organic promotes water consumption growth per unit production in DN Pivikha by 4-15 m3/t, in DN ORLIK by 1-7 m3/t, and in DN SARMAT by 7-15 m3/t. The obtained patterns, for the most part, do not exceed the value of NIR0.05. In general, the duration of the growing season of the plants of the hybrid DO Pivikha was 109 days, and the hybrid DO ORLIK was 122, and the hybrid DO SARMAT was 129 days. These hybrids were in optimal conditions for growth and development and met the declared values of FAO, since for PO Pivikha, the limits of the optimal duration of the vegetation period were determined as 107-115 days, for the hybrid DO ORLIK - 120-125, and for the hybrid DO SARMAT - 128-130 days. \u0000 \u0000Keywords: maize, varietal characteristics, plant growth and development, water consumption, similarity, seeding density \u0000  \u0000 \u0000References \u0000 \u0000Barlog P., Frckowiak-Pawlak K.

These mixtures make it possible to replace partially or entirely wheat with triticale in the diets of animals. It has been found that when 20-40% (by weight) of wheat groats in the grain mixture is replaced with a similar amount of triticale groats, the concentration of radiocaesium in muscle tissue of pigs in the experimental groups reduces by 9.6-9.8 Bq/kg or 30.7-31.3% compared to the control group.

However, sustainable grain production under sharp weather fluctuations is possible only with the agro-technological systems' improvement. The pre-sowing seed treatment with chemical synthesis pesticides remains the primary method in the agricultural industry today. However, pesticides inevitably have a negative influence on the ecosystem of any level. A more environmentally friendly seed treatment method under the intensive technology is the combination of microwave seed irradiation and seed incrustation with the plant growth regulators that increase the cereal crops' yield capacity up to 15–20 %. It is possible to reduce the negative influence of chemical measures on the quality of the cereal crops seeds by using for the seed treatment a mixture of a treatment agent with the preparations having the stimulating properties. The most promising among all physical methods of the pre-sowing seed treatment is the microwave technology, which suppresses the entire complex of the seed infection and can become an alternative to the chemical method of plant protection. The universal character and practical importance of MW technologies combined with the growth-regulating substances consist not only in the increase in the yield capacity of the field crops but also in reducing the technogenic load on the environment. The peculiarity of EMF of EHF application in agricultural production is the necessity to consider the crops' specific electro-physical, technological, and biological properties. High heterogeneity greatly influences the electromagnetic action energy and the final result. \u0000 \u0000Keywords: disinfection, pathogens, seeds, grain, winter wheat, spring barley, microwaves \u0000  \u0000 \u0000References \u0000 \u0000Adamenko, T.I.

Under its influence, the country banned religious travel, including pilgrimage, because many infections occurred. Holy places and pilgrimage routes have been closed around the world. What will be next? Is there a radical transformation of the religious life of humankind, including religious tourism? What measures are being taken by international tourism organizations to mitigate the impact of the pandemic on religious tourism, and how do they see its future? What should be the journey of the future to prevent such global transmission of viruses as happened during this pandemic? This article is dedicated to finding answers to these and other questions that are no less difficult. The authors of the article set themselves essentials to identify and present the critical points that are already relevant for religious tourism and those just beginning to appear and will be important in the post-pandemic era. The study is based on an analysis of recent studies of the impact of the COVID-19 pandemic on religious tourism and travel greening. The conclusions and recommendations are given at the end of the paper. The authors concluded that religious tourism and pilgrimage would recover quickly; however, the post-pandemic tourists will attend to epidemiological safety, so the demand for ecotours and tours with high environmental friendliness will only increase. Religious tourism will also change, involving digital and other technologies.  Keywords: pilgrimage, COVID-19 pandemic, religious studies, religious tourism.   References   Borisova, O.V. (2020).

Thanks to the regulatory mechanisms of biological products, the development of the leaf surface are enhanced, the main functions are essential for the life of sunflower plants, and they are activated by: membrane processes, cell division, respiration and nutrition, the activity of enzyme systems, photosynthesis, a branched root system with enhanced absorbing capacity is created at the growth period. The main goal of this work was to study the influence of the growth of regulatory substances, different in the direction of action, on the morphogenesis, growth, and development, and productivity of sunflower plants of different ripeness groups in the conditions of the Northern Steppe of Ukraine. Moreover, the determination of the most rational stimulants of the growth of sunflower plants, which ensure the resistance of plants to diseases and adverse environmental factors, optimal growth and development of plants, and contribute to obtaining high and sustainable yields of oilseed crops. The laying and carrying out of field experiments was carried out following the generally accepted methodology of experimental work. The experimental part of the work was performed during 2018–2020 on the scientific and research field of the National Scientific and Research Center of Dnipro State Agrarian and Economic University in the stationary experiment of the Plant Science Department in five-crop rotation pure steam – winter wheat – corn – barley – sunflower to study the effectiveness of modern elements in technologies for growing cereals, legumes, and oilseeds. Scientific studies have established that the formation of the maximum leaf surface area of sunflower was observed using the growth stimulant Tseron (0.5 L/ha) to 70.9–78.1 thousand m/ha, or 5.5–10.2% more for control. Here, sunflower plants formed the largest diameter of the basket – 23–26 cm (11.5–30.4% more than the control), and the maximum number of seeds in 829–951 pcs. The highest weight of 1000 seeds was characteristic of the medium-early hybrid Sumico HTS – 54.0–60.0 g, and the lowest for the medium-late Subaro HTS – 51–55 g, due to the biological characteristics of the hybrids. Plant growth stimulants on sunflower contributed to an increase in crop yields 1.01–1.7 times. The most significant increase in grain for all hybrids was provided by the agent Tseron (0.5 L/ha) – 0.16–0.75 t/ha, or 8.2–43.3%. The application of restricted drugs Tseron (0.5 L/ha) and Architect (0.5 L/ha) contributed to the growth of oil content by 3–8 and 4–6 percentage points.","PeriodicalId":23422,"journal":{"name":"Ukrainian Journal of Ecology","volume":"11 1","pages":"106-116"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67601256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental animals were divided into three groups according to the standard deviation value of 0.67 from the average concentration of cortisol in the studied group of animals of the same age during the calving. Blood for the study of cortisol concentration in cows was taken in the morning hours before feeding after a stress load. The stress load was a complex of technological factors associated with blood sampling, fixation of animals for one hour, and the presence of veterinary specialists and support personnel. Among 117 experimental cows, groups of 12 animals were formed to study the cheese suitability of milk and cheese quality. The method of balanced analog groups was applied. The animals were of the same breed, peers in age, average body condition, gentle-dense constitution type, and the intergroup difference in body weight were not reliable. The need for these studies arose due to the constant technological stresses that animals experience in the conditions of their operation, and the effect of the type of stress resistance on the cheese suitability of milk and the quality of rennet cheese produced from it remains an insufficiently studied issue, which determined their scientific novelty and relevance. It was found that milk, which was obtained from cows with high and medium resistance to stress, meets the requirements for raw materials for cheese preparation and has high technological properties, in contrast to peers with low-stress resistance, in which milk according to the fermentation test was attributed to the third class and found unsuitable for the production of rennet cheese. This is evidenced by the twice lengthened phases of milk coagulation under milk-clotting enzyme and double quality of rennet fermenter for its coagulation, which led to a decrease in the quality of the finished product - rennet cheese \"Lyubitelskiy\", which, according to the results of the examination, had a bitter taste and a rubbery consistency. However, the yield of finished products did not depend on the group of cows differing in stress resistance. It is concluded that milk obtained from cows of the first two groups can be used for the production of cheese according to a reduced technological process, as a result of which the energy costs for the production of finished products will be reduced and the cost of cheese will decrease.
