Reservoirs provide an electricity generation, promote the development of water transport, municipal and industrial water supply, irrigation, fisheries, recreation and other economic and social needs. However, calls are increasingly being made to limit the creation of new artificial reservoirs and even to destroy existing ones. The reason for this is the significant and very real negative environmental consequences of their creation and functioning – flooding of large areas of valuable land in river valleys, relocation of large numbers of people to new areas, flooding of low and erosion of high banks of reservoirs, deterioration of river water quality due to stagnation and "blooming” and many others. The aim of this work is to analyze the peculiarities of reforming the shores of the Kaniv Reservoir under the impact of hydrological and morphological processes, measures for the coast protection from erosion, deepening the channel and alluvium of new lands by dredging (mainly in the upper part of the reservoir) are considered. The study of this problem in the reservoirs of the Dnieper cascade, including Kaniv, we started from 1993-1997. Therefore, research methods have changed significantly at different stages. Standard methods of soil science were used to study the impact of the reservoir on the coastal soils, primarily on flooding, waterlogging and soil erosion. Since 2010, more detailed terresrial and water expeditionary routes (land) studies have been started to study the overgrowth of the reservoir with hydrophytic and hygrophytic vegetation with the formation of hydromorphic soils on the islands of the reservoir and its coast. Remote sensing methods of the Earth for analyzing the series of space images Landsat-2, 4-5, 7 and 8 were used to study the temporal and spatial changes of landscapes, as well as geospatial positioning of observation points by GARMIN GPS receiver. The important role of the dams construction and pumping stations to protect the low shores of the reservoir from flooding was noted, which, however, created significant problems in the operation of the facility due to rising electricity prices. Attention is paid to the ecological consequences of the new alluvial lands development within the reservoir water area, in particular to “blooming” and deterioration of water quality, as well as to the limitation of the ability to pass extreme floods and the threat of adjacent territories submergence. The nature of erosion and abrasion of the high right bank was studied with the use of a quadcopter, mainly in the area from the village of Rzhishchiv to the village of Trakhtemiriv. The role of marl clays in weakening the abrasion of shores is emphasized and their vulnerability to destruction is shown. The role and development of ravines on the coast and their participation in the fragmentary formation of hydromorphic landscapes along steep cliffs are noted. On the low left bank there is a reformation of the shores in the area from the villa

This research is motivated because of increasing eutrophication problems in water bodies. This happens as a result of excess nitrogen and phosphorus. Too many of these nutrients can cause algae to grow, leading to blooms. Harmful algal blooms consume dissolved oxygen in water. As a result, the oxygen level decreases, affecting the aquatic ecosystem. The stenobiont plant, which belongs to the group of the most sensitive bioassays, is the small duckweed Lemna minor L. This plant is sensitive to increasing levels of nutrients and blooms of algae. This research aimed to determine the level of water toxicity using the bioassay of duckweed (Lemna minor L.) to establish dangerous concentrations of nitrogen compounds (NO2-, NO3-, NH4+) (CA) for higher plants of aquatic ecosystems with subsequent risk forecast for Dnipro basin. The research was carried out in accordance with DSTU 32426-2013 “Testing of chemicals of environmental hazard. Lemna sp. Growth Inhibition. Test”. The number of effects associated with nitrogen compounds (NO2-, NO3-, NH4+) on plant growth and development during the testing period was detected. The number of green layers is the main variable that was investigated in the experiment. Changes in the morphological features of duckweed were also studied, in accordance with the standard, the toxicity of water was assessed by changes in leaf colour, manifestations of chlorosis, the transformation of whole plants into individuals, the appearance of young leaves. To estimate the number of effects associated with the nitrogen compounds toxicity, the half-maximal effect (EC50) was studied. It should be noted that studies of water toxicity on NO2- content using the Lemna minor L. test showed that even at the lowest concentration of 0.1 mgNO2-/L aquatic biota will be significantly affected by the toxicity with possible subsequent death. Summarizing the results of the research of the Lemna minor L reaction to the toxicity of water with different concentrations of NO3- came to the conclusion that even the lowest concentration (0.1 mgNO3-/L) will have a negative impact on their growth and development of the plant. Generally, 40.0 mgNO3-/L is considered “safe” for fish farming. However, this is not a case for aquatic vegetation, as shown by this result – such concentration will be toxic and cause death. If we take into account NH4+ salts, the reaction was even more progressive, the deterioration of the leaf layers of duckweed began to occur immediately from the first days of the research, and the number of damaged duckweed was 30% more on day 24 than in salts NO3-, NO2-. For algae of aquatic ecosystems the highest level of toxicity is shown by nitrogen compounds in the form of NO3-, the median concentration of EC50 (96 hours) is 7.7 mg/L. Therefore, the regulation of pollution of aquatic ecosystems by nitrogen compounds should be based primarily on the content of NO3-. To avoid the negative effects of compounds such as NH4+ and NO2- it is necessary
由于水体富营养化问题日益严重，促使了本研究的开展。这是由于过量的氮和磷造成的。这些营养物质过多会导致藻类生长，导致藻类大量繁殖。有害藻华消耗水中的溶解氧。结果，氧气水平降低，影响水生生态系统。对生物检测最敏感的一组植物是小浮萍lena minor L.，这种植物对营养水平的增加和藻类的大量繁殖很敏感。本研究旨在利用浮萍(Lemna minor L.)生物测定法确定水生生态系统高等植物的水毒性水平，建立水体中氮化合物(NO2-、NO3-、NH4+) (CA)的危险浓度，并对该流域进行风险预测。该研究是根据DSTU 32426-2013“环境危害化学品的测试”进行的。生长抑制。测试”。测定了试验期氮化合物(NO2-、NO3-、NH4+)对植物生长发育的影响数量。绿层数是实验研究的主要变量。还研究了浮萍形态特征的变化，按照标准，通过叶片颜色的变化、黄化的表现、整株向个体的转变、嫩叶的外观来评估水的毒性。为了估计与氮化合物毒性相关的效应数量，研究了半最大效应(EC50)。值得注意的是，利用小扁豆试验对NO2-含量的水毒性研究表明，即使在最低浓度为0.1 mgNO2-/L的情况下，水生生物群也会受到毒性的显著影响，并可能导致死亡。总结了不同浓度NO3-水对小草草L毒性反应的研究结果，得出即使最低浓度(0.1 mgNO3-/L)也会对其植物生长发育产生负面影响的结论。一般来说，40.0 mgNO3-/L被认为是鱼类养殖的“安全”水平。然而，这不是水生植物的情况，正如这个结果所显示的那样-这种浓度将有毒并导致死亡。如果考虑NH4+盐，则反应更为渐进，从研究的第一天开始，浮萍叶层的退化就立即发生，第24天的浮萍受损数量比NO3-、NO2-盐多30%。对水生生态系统藻类毒性最大的是NO3-形式的氮化合物，其EC50 (96 h)的中位数浓度为7.7 mg/L。因此，氮化合物对水生生态系统污染的调控应主要基于NO3-的含量。为了避免NH4+和NO2-等化合物的负面影响，有必要考虑它们的毒性水平:EC50(96小时)NH4+ - 250 mg/L, EC50(96小时)NO2- - 720 mg/L。综上所述，自由漂浮的水生植物lena minor L.是一个很有前途的测试对象，因为它很容易吸收所有元素并迅速显示结果。它能够迅速积累有害物质，因为在生命的过程中，它的叶子绝对吸收了所有落入水中的元素。

Organizational production of agricultural products is used to preserve the natural environment and to preserve the quality of the products. The development of organic wines in the light of 100 years and over the course of the period has become insane, as for the correct organization of it, you can preserve ecological, social, and commercial transfers. The organizational structure has become a warehouse part of the bio-economy and circular economy, which is a priority for the economic development of the European Union, the USA, Great Britain, the Great Britain, the Republic of Korea, Japan, and the United States of America. For determining the prospects and problems of organic production of agricultural products, general scientific methods were used such as publicity, systematization, analysis, and synthesis, of the scientific literature and normative documents. For an additional analysis of regulatory documents, a procedure for certifying the authorities of the United States, the European Union and Ukraine has been established. Ukraine, in turn, began to take the first steps towards organic production in the late 1990s. It was at this time that she began to grow organic grain and opened export lines for its transportation to other countries, mainly Europe. Ukraine remains a leader in the production and export of organic cereals. Export competitive advantages of national agar products are lower production costs and logistics support. Ukraine continues to increase its organic production capacity - an increasing number of operators are appearing in this sector of agricultural production. As of 2019, the share of organic production of crop products in Ukraine is 1.4% (5th place in the world in terms of growth rate of organic agriculture), which is 467.9 thousand hectares of the total area of agricultural land in 32, 7 million hectares, as well as 470 operators of organic production. The dynamics of changes in organic agricultural production in Ukraine indicates a general trend of increasing their number, but in some periods, there is a decrease due to the economic and political situation in the country and changes in legislation in this area. Ukraine has significant advantages of organic production, which include a high level of soil fertility, favorable climatic conditions, traditional orientation as an agrarian state. Also, the price of Ukrainian products is lower than the minimum price of organic products of European countries. In the organic production of crops use methods that optimize the biological activity of soils, provide a balanced supply of nutrients to plants. At the same time, there are problems in Ukraine that hinder the development of organic production.

The quantitative indicators of land growth in the Ukrainian part of the Danube delta are considered. Comparison of Landsat satellite images in three key areas of the delta showed that for the period 1975-2020 the area of wetlands at the mouth of the Сhilia channel increased by 1448 hectares due to the accumulation of sediments between the Starostambul and Limba branches and their overgrowth with vegetation. In the area of the Bystroe channel, the area of new lands increased by 1037 hectares due to the artificial deepening of this channel for the Ukrainian ships passage into the Danube River and the deposition of sediments along the coast. A slightly smaller increase in land cover (797 ha) was found in the northern part of the coast of the Ukrainian part of the delta, where saline and carbonate soils are formed. In the future, active land growth is expected in the Musura bay between the mouths of the Starostambul and Sulina branches, ie at the contact of Ukraine and Romania. Some changes in these parameters are expected after a powerful flood in 2021, which will become known after the establishment of a relative equilibrium between the processes of accumulation and erosion after this extreme event.

Under market conditions, the increase in wool and lamb production should not only increase the livestock number, but also increase its productivity. The significant reserve is also to improve the quality of raw materials produced. The aim of the research was to identify the features of wool and meat productivity in young rams of the Taurian type Askanian fine fleece breed the taking into account an in-depth assessment of the washed fiber yield and subsequent use of the obtained data in the selection-breeding work with sheep. The young rams of the Taurian type Askanian fine fleece breed were used for research. The formed groups were characterized by low, medium and high yield of washed fiber. The results of the studies showed an advantage in all research parameters in young rams with an average yield of washed fiber. Therefore, it is proposed to direct the selection-breeding work to improve live weight and physical and mechanical properties of wool in young rams with high yields of washed fiber (more than 60.1%), which will allow to obtain more profits not only from the wool sale but from the sale of mutton, and to reject lambs with a low washed fiber yield to prevent the transmission of this trait to their offspring.

Artificial light, as an environmental factor, is crucial for the release of hormones that play a key role in a bird's life, growth, immunity and reproduction. For laying hens, light plays an important role in the development and functioning of the reproductive system, significantly affecting the age of laying the first egg, egg-laying and productivity in general. The source of artificial light of the latest generation in poultry farming is LED lamps. Compared to incandescent and fluorescent lamps, LEDs have a longer service life, specific spectrum, lower heat output, higher energy efficiency and reliability, as well as lower maintenance costs, so they are increasingly used by manufacturers. LEDs are a special type of semiconductor diode that can give monochrome light. However, information on the effect of monochrome light with different wavelengths of light on the physiological state of the hens’ body is quite contradictory. Therefore, the aim of the work was to study the efficiency of egg production using monochrome light with different wavelengths. For this purpose, in the conditions of a modern complex for production of food eggs in a poultry house with an area of 2915 m2, 4 groups of hens of the industrial herd "Hy-Line W-36" were formed, each of which was kept in a separate poultry house similar in area and cage equipment. Each poultry house was equipped with cage batteries "Big Dutchman" (Germany), consisting of 1176 cages with an area of 40544 cm2 (362 × 112 cm). The differences between the poultry houses applied only to LED lamps. Thus, hens of the 1st group were kept using LED lamps with a peak light wavelength of 458 nm (blue color of the spectrum), the 2nd group – 603 nm (yellow color of the spectrum), the 3rd group – 632 nm (orange color of the spectrum) and the 4th group – 653 nm (red color of the spectrum). Every day, for 44 weeks of the productive period, the number of eggs laid by the laying hens of each group and the intensity of their laying were determined. The number of hatched hens (due to death and culling) was also counted daily and the number of livestock was determined. Once a week, the weight of eggs and live weight of laying hens were measured from certain labeled cages according to a sample. The European egg production rate on the basis of productivity was determined. It was found that for the maintenance of laying hens of modern white-egg crosses in 12-tier cage batteries of classical designs, it is advisable to use lighting with a peak wavelength of 653 nm, that is with red light. This makes it possible for the 44-week egg-laying period to receive an additional 4.8–18.8 million eggs from each poultry house (0.4–1.6 thousand eggs per 1 m2 of its area) at the highest level of the European egg production rate at 1.0–3.8 units The decrease in the peak wavelength from 653 to 632 nm, which was manifested by a change in light from red to orange, was accompanied by a decrease in the preservation of livestock by 0.7% (3.8% ˂

For laying hens, light plays an important role in the development and functioning of the reproductive system, significantly affecting the age of laying the first egg, egg-laying and productivity in general. The source of artificial light of the latest generation in poultry farming is LED lamps. Compared to incandescent and fluorescent lamps, LEDs have a longer service life, specific spectrum, lower heat output, higher energy efficiency and reliability, as well as lower maintenance costs, so they are increasingly used by manufacturers. LEDs are a special type of semiconductor diode that can give monochrome light. However, information on the effect of monochrome light with different wavelengths of light on the physiological state of the hens’ body is quite contradictory. Therefore, the aim of the work was to study the efficiency of egg production using monochrome light with different wavelengths. For this purpose, in the conditions of a modern complex for production of food eggs in a poultry house with an area of 2915 m2, 4 groups of hens of the industrial herd \"Hy-Line W-36\" were formed, each of which was kept in a separate poultry house similar in area and cage equipment. Each poultry house was equipped with cage batteries \"Big Dutchman\" (Germany), consisting of 1176 cages with an area of 40544 cm2 (362 × 112 cm). The differences between the poultry houses applied only to LED lamps. Thus, hens of the 1st group were kept using LED lamps with a peak light wavelength of 458 nm (blue color of the spectrum), the 2nd group – 603 nm (yellow color of the spectrum), the 3rd group – 632 nm (orange color of the spectrum) and the 4th group – 653 nm (red color of the spectrum). Every day, for 44 weeks of the productive period, the number of eggs laid by the laying hens of each group and the intensity of their laying were determined. The number of hatched hens (due to death and culling) was also counted daily and the number of livestock was determined. Once a week, the weight of eggs and live weight of laying hens were measured from certain labeled cages according to a sample. The European egg production rate on the basis of productivity was determined. It was found that for the maintenance of laying hens of modern white-egg crosses in 12-tier cage batteries of classical designs, it is advisable to use lighting with a peak wavelength of 653 nm, that is with red light. This makes it possible for the 44-week egg-laying period to receive an additional 4.8–18.8 million eggs from each poultry house (0.4–1.6 thousand eggs per 1 m2 of its area) at the highest level of the European egg production rate at 1.0–3.8 units The decrease in the peak wavelength from 653 to 632 nm, which was manifested by a change in light from red to orange, was accompanied by a decrease in the preservation of livestock by 0.7% (3.8% ˂ ","PeriodicalId":362367,"journal":{"name":"Naukovì dopovìdì Nacìonalʹnogo unìversitetu bìoresursiv ì prirodokoristuvannâ Ukraïni","volume":"60 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133524107","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 article investigates the influence of the application of different systems of basic tillage on the quality of winter wheat grain in short crop rotations of the Southern Steppe of Ukraine. It is established that the grain quality of winter wheat in the Southern Steppe of Ukraine is mainly determined by the genetic characteristics of the variety, but also largely depends on the conditions and technologies of cultivation. In winter wheat grain, which is used for food purposes, reserve proteins are important, which in winter wheat determine the baking properties of flour. In drought conditions, when the yield of winter wheat decreases, the protein content in its grain tends to increase. In wet years, on the contrary, there is a reverse pattern. According to experimental studies, wheat varieties have a negative correlation between grain protein content and yield. It is established that during 2016–2020 research shows almost the same pattern of action of different predecessors and systems of basic tillage on the formation of grain quality of winter wheat in arid conditions. It was found that, on average, according to all variants of research, only with the use of the system of tillage-free tillage received grain of winter wheat with a protein content of 12,5%, which met the requirements of the 2nd class. It is recorded that on average over five years of research on all tillage systems, grain of winter wheat with gluten content was obtained, the quality of which corresponded to the 3rd class. Different tillage systems caused a slight impact on the gluten content, which ranged from 20,6% to 21,1%. It is determined that the precursors have a certain effect on the protein content in the grain of winter wheat. The analysis of qualitative indicators showed that on average in five years of research, when growing winter wheat after a pair of black and a pair of green wheat with winter vetch, grain was formed, which in terms of protein content corresponded to the 2nd quality class. More protein was accumulated in winter wheat grain after a pair of black, which was 12,9%. After peas for grain, as well as a pair of green with a mixture of white mustard and peas, received a grain of winter wheat, which was the 3rd quality class. It was found that on average in five years of research, all variants of winter wheat were grown with gluten content, which met the requirements of the 3rd class. Black vapor and green vapor with winter veneer caused the accumulation of gluten at almost the same level with a small increase in the version with winter vetch up to 21,8%. The lowest level of gluten was obtained in the grain of winter wheat after peas per grain, which was 19,7%. In all variants of the experiment, sidereal steam with winter tillage and the use of tillage-free tillage had the best effect on the growth of winter wheat grain quality indicators.

Among a number of antibacterial drugs, the share of fluoroquinolones used to treat bacterial infections is 25 % of the total number of pharmaceuticals available on the world market. Because fluoroquinolone antibiotics are low in toxicity, have a broad spectrum of antimicrobial activity and favorable pharmacokinetic properties. In particular, danofloxacin – belongs to the fluoroquinolone antibiotics and has no natural analogues, because it is made by artificial synthesis, and therefore does not cause addiction to pathogenic microorganisms. Danofloxacin mesylate (danofloxacin) is the main active ingredient of the new veterinary drug Danoxan-50, used in veterinary medicine for the treatment of respiratory and gastrointestinal diseases of cattle, pigs and chickens. However, poultry meat contains residues of antibiotics that change its microflora, which leads to negative effects on the end user. Scientists have proved that the products of poultry slaughter raised on poultry farms in Ukraine contain residual amounts of antibiotics: penicillin series, tetracyclines, streptomycin and some feed antibiotics – grisin, bacitracin and nisin. However, the increased demand for chicken food has led to the creation of crossbred broiler chickens with an increase in slaughter weight. This had a negative effect on the genetics of these animals, for example, on the occurrence of spontaneous idiopathic muscle abnormalities. In addition, the quality of poultry meat is affected by the age and period of molting, the use of feed additives in poultry feeding and chronic heat stress and oxidative stability of muscles. All of these factors can affect the quality of poultry. At the same time, the most important indicator of food quality is biological value, as an integral expression of their various properties: chemical composition, nutritional value, safety, biological activity, and determines the degree of compliance with optimal human needs. In the context of expert confirmation of the safety of meat with the use of antibiotics in the treatment of poultry is the level of its biological value, the amino acid composition of proteins. Thus, scientists have found a reverse trend in the ratio of essential to essential amino acids in the studied muscles (respectively – 25.2% and 6%), as well as identified an amino acid that limits the biological value of the protein - methionine. The aim of the study was to investigate the amino acid SPEED of broiler meat during experimental feeding of the antibacterial drug Danoxan-50.

One of the main directions of fodder production intensification is the cultivation of fodder crops and fodder harvesting from them at the lowest cost of energy and labor resources, the maximum yield of fodder products per unit area, and 1 UAH of production costs. To successfully perform this task, it is necessary, first of all, to increase the productivity of forage crops, the use of cost-effective and energy-saving technologies and increase the efficiency of fertilizer application. One of the most valuable perennial legumes is sainfoin, which is characterized by high fodder value, unpretentiousness to growing conditions and has great agronomic value. At the same time, the existing technologies for growing sainfoin for fodder purposes remain energy- and resource intensive. The aim of the research was to determine the influence of mineral fertilizers and seed inoculation on the economic and energy efficiency of the sainfoin growing technology on green fodder. Experimental studies were conducted during 2016-2018 on the research field of the Department of Forage Production, Land Reclamation and Meteorology, located in the NULES of Ukraine "Agronomic Research Station" on typical low-humus chernozem. Experimental research was conducted during 2016-2018 on the research field of the Department of Forage Production, Land Reclamation and Meteorology, located in the NULES of Ukraine "Agronomic Research Station". The scheme of the experiment included the following factors: factor A - varieties of sainfoin: Amethyst Donetskyi, Adam, Smaragd; factor B - fertilizer, inoculation: 1) without fertilizers, 2) N45R60K90 + seeds inoculation, 3) P60K90 + seeds inoculation. As nitrogen fertilizer was used ammonium nitrate 34%, phosphorus - simple superphosphate 19%, potassium - potassium salt 56%. Method of sowing - row, spring, coverless. Inoculation was performed by Rhizotorphin. Economic evaluation of the results of field experiments was carried out in accordance with generally accepted methods developed by the Institute of Cereals NAAS, the Institute of Feed and Agriculture of Podillya NAAS, NSC "Institute of Agrarian Economics" and other research institutions. Calculations of energy efficiency of growing sainfoin for green fodder were calculated according to the "Methodology of bioenergy assessment of technologies for the production of livestock products and feed." According to the economic assessment, the calculations of monetary and material costs are performed taking into account the full mechanization of works. The costs for them are calculated according to the technological maps developed in the process of research. The cost of seeds, fertilizers and fuel was taken at wholesale prices as of January 1. 2019, 1 ton of fodder units of sainfoin was equated to the cost of 1 ton of feed grain. According to the results of research, it was found that when setting up an experiment with different varieties of sainfoin, both with the introduction of mineral fertilizers
