Introduction. Processing of grain raw material with influence on starch or albumens by application of heat treatment creates the variety of functional properties of a product and is perspective in the modern terms vital functions of man. Research methods and methods. The flour obtained from wheat of the Ascanian wheat and from wheat of the soft varieties: Sophia ("sweet wheat"), Blond (soft) and Chornobrova (enriched with micro- and macronutrients) were used in the study. Thermal modification of flour samples was carried out in a convective manner. The control sample for determining the quality indicators is obtained in industrial conditions, extruded wheat flour produced by LLC "AS groups, LTD". Research results. The obtained kinetic dependence shows the gradual loss of moisture standards with different speed which accordingly influences on duration of drying. The moisture content of the drying agent most affects the intensity at the initial stage of the constant drying rate. With an increase in the moisture content of the coolant, the period of constant drying increases and the amount of evaporated moisture increases during this period. With the subsequent removal of moisture from raw materials, the degree of influence of this parameter on the intensity decreases. The nature of the drying curves is the same and the recommended process for obtaining modified flour is the process duration of 300 minutes or 5 hours. It was determined microscopically, that the samples of dried wheat flour have a purpose and are partially destroyed by starch granules and amorphization of biocomposite materials. Based on the data on the kinetics of drying flour samples, the kinetic coefficients and values of the critical moisture content for drying wheat flour were calculated, which is 1.18-1.30 %. It was determined that for the sensorial indicators the obtained samples have indicators characteristic of the varietal characteristics of wheat, from which the flour was taken. In terms of physical and chemical parameters, the modified wheat flour samples are not inferior to the well-known industrial sample of extruded flour. Conclusions. Use of flour, obtained from the wheat with different correlation of amilose and amylopectin, positively influences on a technological process and allows to extend the assortment of modified starch products, and accordingly, food products. Kinetics of the convective drying standards of the flour is investigated. Researches showed that a it is physically modified flour obtained from the different sorts of the soft wheat is not inferior in quality to the extruded wheat flour.

Authors:   Institute of Technical Thermophysics of the NAS of Ukraine, Kyiv, Ukraine, Sheiko Tamila
Published: July 2021

During the processing of frozen and thawed sugar beets, invert sugar, in particular glucose and fructose, accumulates in them. This is due to the process of hydrolysis of carbohydrates. As a result of temperature fluctuations, beets lose elasticity, and tissue walls become soft. The activity of microorganisms intensifies on damaged beets. In the sugar industry, harmful microorganisms enter the production with raw materials, water, unwashed soil and air. Under improper storage conditions of raw materials the rapid development of microorganisms begins leading to sugar loss. The microflora of raw materials in sugar production is due to spore-forming and non-spore-forming bacteria, as well as micromycetes. Processing in the production of such raw materials is complicated. This leads to non-rhythmic operation of the sugar factory, technological processes and metal corrosion of technological equipment. Sugar yield and quality are significantly reduced. An important factor is the protection from the formation of microbial biofilms. The article considers the problem of formation of microbial biofilm in the process of obtaining diffusion juice in the sugar industry. The structure of the biofilm and its stability over time are considered. Under the conditions of active biofilm formation, uncontrolled unaccounted losses of sucrose are observed. Under conditions of low-quality beet processing, biocides and enzymes must be used in the production. They reduce the contamination of intermediate products by microorganisms, greatly facilitate the technological process. They also allow you to predict unaccounted sugar losses and improve its quality and yield. The article considers the effect of different types of biocides on dextran, which is an example of the formation of microbial biofilms. The comparative characteristic of influence of biocides on dextran is given and their resistance is noted.

Cheeses produced using traditional technology usually contains 45 % 50 % of milk fat in dry matter, therefore they are classified as high-calorie foods and are not recommended to be included in the diet of people who need dietary nutrition. In the European countries, dietary low-calorie rennet cheeses are widely represented in the trade network, and in Ukraine such products are quite rare, expensive and usually of foreign production. Milk fat is an important structural and flavoring component of rennet cheeses and a significant decrease in its content in milk leads to a product of low consumer quality with problems such as unexpressed taste, coarse, rubbery consistency. In proportion to the decrease in the mass fraction of fat in the cheese, the disadvantages are more pronounced. The solution to this problem requires an integrated approach, which consists in the correction of technological methods for the production and maturation of cheese and the optimization of the composition of fermented microflora. It is possible to improve the sensorial characteristics of low-calorie cheeses by introducing into their structure exopolysaccharides (EPS) – high-molecular polymers synthesized by some strains of lactic acid bacteria (LAB). Research subject: biological and technological properties of LAB. The aim of this work is to search for strains of LAB with given physiological and biochemical characteristics for further use in the production of dietary rennet cheeses with a reduced mass fraction (MF) of fat. The common microbiological and technological research methods were used in the work. Research results. The expediency of using sucrose as the only source of carbohydrate nutrition for screening LAB with EPS-activity has been shown. Six strains of LAB identified as Streptococcus thermophilus, Lactobacillus bulgaricus, Lactobacillus plantarum and Leuconostoc mesenteroides were withdrawn from non-commercial fermented milk products and studied for their technological properties. In laboratory conditions, the expediency of using LAB with EPS-activity for the production of cheese with a reduced MF of fat has been confirmed. The use of new cultures LAB in the composition of the starter culture allowed increasing the moisture content in the cheese by (6.5 8.3)% compared to the control and to improve its texture and taste. Scope of research results application. The use of LAB-producers of EPS will improve the consumer characteristics of rennet cheeses with reduced fat content, expand the domestic range of these products, increase their biological value, will have a positive effect on the health of people who need dietary nutrition, as well as all population groups.

The subject of research - socio-economic, political and economic-mathematical models. The aim of the article is to study the theoretical and methodological principles of determining the content of categories and areas of application of socio-economic, political, economic and mathematical models in Ukraine and the world. The article analyzes the process of formation of the socio-economic model of the state and the factors that affect it, as well as compares the main types of modern socio-economic models: welfare state, minimal state, developmental state). The advantages and disadvantages of these models, their characteristics, examples and results of their application in different countries at different stages of development were identified. It is shown that the success of state-building processes depends on the type of socio-economic model used by the country. It was found that in the modern world there are no socio-economic models in "pure" form and "classical" models contain elements of other models. The thesis is confirmed that periodic adjustment or even change of models is justified. The main models of political and managerial relations in the system of public administration are analyzed. The political model inherent in Ukraine has been determined. The necessary preconditions for the stable development of political relations have been established. The article analyzes the modern economic and mathematical apparatus for modeling and forecasting the performance of the state budget and macroeconomic indicators of the country. Econometric methods that are quite common in the practice of modeling and forecasting of financial and economic activities are directly considered and compared; normative balance methods (model of inter-sectoral balance); expert systems, among which we can distinguish systems based on fuzzy logic; artificial neural networks; simulation models (Monte Carlo method, system-dynamic modeling); models of general economic equilibrium. Based on the research, the advantages and disadvantages of the methods used in this area are highlighted, and a number of proposals for their application in the economy of Ukraine are formulated.

Authors: Zhuravlov O. V. , Shatkovskyi A. P. , Vasiuta V. V.
Published: July 2021

Based on the results of observations, it was specified that when decreasing soil moisture there is a disproportionate decrease in the average daily evapotranspiration (ET). Thus, in the range of soil moisture of 94-80% minimum moisture-holding capacity (MMHC) ET was 9,76 mm a day, and in the range of 70-62% MMHC - its value decreased by 3 times. When the soil moisture reached 58,5% MMHC, the value of ET did not exceed 0,5 mm a day, which is 20 times less than the initial one. It was determined that the decrease in soil moisture by 10% in the range of 90 - 70% MMHC occurs during 3 days, and from 70 to 60% MMHC and from 60 to 58% MMHC - during 8 days. When soil moisture is 70% MMHC and below, the actual evapotranspiration is less than ETo that proves the effect of water stress on soybeans ET. When calculating water stress coefficient (Ks), a mathematical model based on the dependence of Ks on soil moisture as a percentage of MMHC was obtained. The average absolute percentage error (MAPE) is 8,6%, which corresponds to the high accuracy of the obtained dependence. In the range of soil moisture from 58 to 80% MMHC, the water stress coefficient is calculated by the formula Ks =-0.0011·FC²+0.1925·FC-7,4541. When having soil moisture as 80% MMHC and above, Ks = 1. A comprehensive comparative assessment of existing methods for calculating waster stress coefficient Ks was taken and it was found out that the actual values of Ks when having soil moisture as 80-70 and 60-65% MMHC by 8-14 % and 72-32 %, respectively, less than Ks FAO 56, and by 35-40 % larger than those determined by Saxton method. It was proved the need of taking into account the reduction in evapotranspiration when calculating water balance under water stress of plants. The calculation of evapotranspiration (ETs) by the Penman-Monteith method, without taking into account the water stress coefficient, showed that the value of the actual and calculated water balance coincides only when soil moisture does not exceed 62% MMHC. With a further decrease in soil moisture, the estimated soil moisture was 20% less than the actual, which led to the errors in determining soil moisture after irrigation, because its actual value was almost 100% MMHC, and the estimated one was only 60% MMHC. It was proved that the determination of water balance by calculation methods without taking into account the water stress coefficient leads to significant errors.

Cultivation of nightshade family crops (Solanaceae) requires sufficient amount of moisture and heat. In Ukraine, the most available conditions for that are in the southern regions: Kherson, Mykolaiv, Odesa, Zaporizhia and AR of Crimea, where the average yield of tomatoes is about 30 t/ha, and planting area is about 470 thousand hectares. Tomatoes are the main host plants for the South American tomato moth. Leaves, fruits and vegetative buds damaged by these pests, become a kind of «gateway» for the infection of plants by fungal pathogens. Feeding of phytophagous on the fruits of tomato leads to their falling off. Yield losses can reach 100%. This pest has high adaptability to climatic and natural conditions, capable for reproductive activities throughout the year. Among the factors contributing to the spread of these pests at the intercontinental level, the most important is the uncontrolled trading of infected fruits with plant particles, and the local spread from one field to another due to the ability of adult moths to fly. The searching of scientifically grounded methods of control of South American tomato moth, in particular, the study of the effectiveness of modern insecticides by means of spraying and drip application along with applying irrigation against this pest in the Steppe of Ukraine is very actual.

During the phytosanitary evaluation of experimental plots of tomatoes before treatment with insecticides, a high number of larvae of South American tomato moth was found, which in the check plots averaged 3,1-7,0 number/plant before the first application of insecticides, and 9,1-20,6 number/plant before the second one. Insecticide Exirel, SE (cyantraniliprole 100 g/l) with the consumption rates of 1,0 l/ha and 1,5 l/ha when providing double spraying in a small-plot experiment on open ground tomatoes provided the effectiveness against tomato moth caterpillars at 91,1% and 99,5% on the 3rd day after application, and the duration of its toxic effect exceeded 14 days. In the conditions of protected soil when applying the insecticides along with drip irrigation the insecticide Verimark CS (cyantraniliprole, 200 g/l) with the rates of 0,5 and 0,75 l/ha provided the effectiveness against tomato moth caterpillars in 3 days after application on the average by 92,4-100,0%, and the duration of its toxic effects was more than two weeks. Applying insecticides along with drip irrigation due to their local application provided high efficiency of insecticides against phytophagous larvae, having a rather long duration of toxic effect, compared with spraying.

Authors: Riabkov S. V.
Published: July 2021

According to the results of previous studies it was specified that the soils of the research areas in south of Ukraine are not provided with the optimal content of nutrients for normal growth and development of fruit crops. As a result of that, a long-term field experiment was set up, which aimed at increasing soil fertility, yield and fruit quality of intensive plantations of peach and apple trees under drip irrigation as well as at improving soil management principles. The field experiment was set up in 2009 on the perennial plantations in Kherson and Mykolaiv regions on the soils with different properties using the water of different quality when applying traditional cultivation technology in the south of Ukraine. It was observed the positive effect on the yield of perennial plants when applying the following fertilizer systems: organic-mineral ("Rost-concentrate"), mineral (N120P30-90K75-120), and organic ("Gumoplant") when irrigating with water of different quality. Thereat, the soil moisture in the layer of 0-60 cm was in the range of 75–90% of MMHC depending on the soil grading. The highest increase in peach yield (33%), in comparison with the check plot was observed on sod sandy soils in SE "DAF named after Solodukhin" in Kherson region when applying mineral fertilizers. The higher dry matter content in fruits by 2,6% and nitrate content by 29% were also observed when using mineral fertilizers on this farm. The highest yield increase up to 21,16 t/ha on dark chestnut medium loam soils in private joint stock company "Radsad" in Mykolayiv region in apple orchards was obtained when using organic-mineral fertilizers and irrigating with partially suitable water. The yield increase up to 26,81 t/ha was obtained on chornozem southern heavy loam soil in private joint stock company "Kamyanskyi" in Kherson region when irrigating with water suitable for irrigation and up to 32,62 t/ha of yield increase was obtained on dark chestnut medium loam soil in "Bilozerskyi" state farm in Kherson region when irrigating with water suitable for irrigation. Higher dry matter contents were recorded under mineral fertilizers, higher sugar content - under organic-mineral and mineral fertilizers, nitrate content under organic fertilizers. The content of nitrates under different fertilization systems for all fruit trees did not exceed the maximum concentration limit of 60 mg/kg. It was also found out that the highest effect on the yield of perennial plantations had organic-mineral fertilizers with a correlation coefficient of 0,75.The results of mathematical data processing showed that the fertilizers applied along with drip irrigation (fertigation) had a positive effect on the yield of peach and apple trees and the quality of their fruits.

Authors: Vyshnevskyi V. I. , Demianov V. V.
Published: July 2021

The relevance of research is the lack of actual parameters of the Dnipro Сascade. 

The purpose and objectives of the study are to specify the actual parameters of the Kamianske Reservoir, which is the part of the Dnipro Cascade.

Methods and techniques. The study was based on using the actual Navigation map of the Kamianske Reservoir. The available data were processed when using AutoCAD program. The satellite images were used as well.

Results and main conclusions. It was identified that the main parameters of the Kamianske Reservoir, which is the part of the Dnipro Cascade, significantly differ from those obtained earlier, in particular, which are given in the operation rules of the Dnipro Сascade. The most important parameters of the Kamianske Reservoir to keep normal retention level (64.0 m) are as follows: water area (water surface) – 537 km2, total volume – 2636 million m3, useful storage capacity – 495 million m3. A small increase in the total volume compared to the project one is supposed to be the result of significant extraction of construction raw materials from the bottom of the reservoir. The reservoir length, depending on the ways of measuring, varies from 119 to 137 km. It was determined that the actual maximum depth of the reservoir (23 m) is significantly larger than it is indicated in reference books. The actual average depth of 5.8 m is significantly larger as well.

Some parameters of the reservoir, which were previously ignored by researchers, are given as a result of the study. This parameter, in particular, is the area of the islands, which is 48.9 km2. The area of shallow water with depths less than 2 m is 152.4 km2. This area is mainly located in the upper and middle parts of the reservoir – mainly near the left bank. An important parameter is the cross section of the central reach of the reservoir, where the main movement of water is observed. Depending on the length of the reservoir, this cross-section varies in the range of 17,900–20,600 m2. The smallest cross-section is a characteristic feature of the upper part of the reservoir that causes an increase in flow velocity above 1.0 m/sec. It was concluded that the existing operation rules of the Dnipro Сascade does not correspond to the present and require the radical improvement. A mandatory requirement for the new rules is specifying the modern parameters of the reservoirs, built on the Dnipro River. Perspectives. There is need to specify the parameters of all reservoirs of the Dnipro Сascade. It is a basis for the development of new operation rules for the Dnipro Сascade.
Water consumption and irrigation regime of seed alfalfa under the conditions of regional climate change in the southern Steppe of Ukraine
Authors: Holoborodko S. P. , Dymov O. M.
Published: July 2021

The article presents the results of scientific research to specify the seed productivity of alfalfa grown on irrigated and rainfed lands of the southern Steppe of Ukraine. It is proved that obtaining stably high yields of conditioned alfalfa seeds under the conditions of regional climate change is possible only providing an optimal supply of productive moisture in the soil, since in recent years the crop has been grown under high temperature conditions and insufficient precipitation. It was established that irrigation of seed alfalfa throughout the growing season regardless of cultivar and mowing, should be conducted in two interphase periods: "the beginning of regrowth (shoots) – early budding" and "the beginning of budding – beginning of flowering". In the first interphase period, it is necessary to create conditions for optimal growth and development of plants that is achieved by maintaining the level of pre-irrigation humidity in 0-100 cm layer in the range of 70-75% MMHC on dark chestnut soils and 55-60% – on sandy loam chernozems. In the second interphase period, it is necessary to provide optimal conditions for the development of production processes and the formation of conditioned seed yields that is achieved by inhibiting growth processes, since alfalfa tends to grow up. Therefore, the level of pre-irrigation humidity of the calculated layer on medium and heavy loamy soils should be maintained within 60-65% MMHC and 45-50% MMHC – on sandy loam chernozems. The analysis of changes in natural and climatic conditions carried out over the past years shows that in the subzone of the southern Steppe, alfalfa cultivation for seeds is possible only by providing the developed irrigated agriculture. Getting the deficit of natural moisture solved, combined with high availability of heat resources and fertile dark‑chestnut soils and southern chernozems, is an objective natural prerequisite for further growth of seed productivity of alfalfa and reducing its dependence on extreme weather conditions and, above all, in medium‑dry (75%) and dry (95%) precipitation years.

Published: July 2021

The balance method of determining the share of Kryvyi Rig Basin enterprises by the accumulated volume of mine water in the storage pond was considered. The balance method of participation of mining enterprises by the shares of mineral substances was formalized. An integrated approach of the control of water removal into the storage pond when using linear convolution of two balance equations by both the share of water volumes and the mineralization rate in the water discharges of enterprises was developed. It takes into account the choice of equity participation in mine water removal by economic and environmental criteria.

The algorithm of equity participation of mining enterprises of Kryvyi Rih Basin on the principles of equality of two criteria was substantiated. The calculations of the share of discharge water accumulation in the storage pond of the Svistunov gully were carried out. The estimated price for water removal of one cubic meter of water into the storage pond by two criteria was considered. The estimation criteria are the volumes of pumped water and mineralization rate. Graphical dependences of the estimated price on the ratio of discharges concentration of different enterprises to the mixture concentration were built. Different estimation coefficients were used: paid water removal by water volumes; assessment of water removal only by mineralization rate; equal approach by the volumes (50%) and mineralization rate (50%). The calculations showed the efficiency of the algorithm, the applicability of its use by enterprises for integrated control of mine water removal by the criteria of volume and mineralization rate.

The proposed balance method can be easily generalized when using other indicators of water quality (chlorides, sulfates, etc.), which are considered to be the most relevant for determining the equity participation of enterprises. In the future it is necessary to develop a theory of paid water use and water removal in conditions of unsatisfactory water quality, taking into account the integrated approach by different indicators that means multi-criteria assessment of water removal and accumulation of mine water.

Published: July 2021

The influence of plant nutrition area and mineral fertilizer rates on the productivity of St. John's wort (Hypericum perforatum L.) by using transplant reproduction method in the conditions of drip irrigation was studied. It was proved that the transplant method of cultivation of St. John's wort under drip irrigation is a very effective method of reproduction of this crop. Four variants of  planting density per unit area were studied: 42 thousand plants / ha (cultivation scheme 60x40 cm), 56 thousand plants / ha (60x30 cm), 83 thousand plants / ha (60x20 cm) and 167 thousand plants / ha (60x10 cm). Yield recording of raw materials (air-dry tops) was carried out in the phase of mass flowering. In the first year of vegetation this period was in the first decade of August, in the second year – in the second decade of June. It was found that the increase in the number of planted plants of St. John's wort per 1 ha contributed to the increased plantation productivity. When having a cultivation plant density of 42,000 plants / ha, the yield of dry grass in the first year of vegetation was 3,02 t / ha. Increasing the number of plants to 56 thousand plants / ha provided 3,26 t / ha of raw materials. The highest yield of dried St. John's wort – 3,76 t / ha in the first year of vegetation was obtained in the variant with the largest number of planted plants per unit area - 167 thousand plants / ha. In the second year of vegetation of St. John's wort in the variant with the lowest plant density of 42 thousand plants / ha, the yield was 3,65 t / ha. The most productive plantation of the second year of vegetation was in the variant with a plant density of 83 thousand plants / ha, where the yield of dry raw materials was 3,96 t / ha. A further increase in the number of plants per unit area led to a decrease in crop yields. The influence of four variants of the main application of mineral fertilizers on the productivity of St. John's wort was also studied: N0P0K0 (reference), N60P60K60, N120P120K120 and N180P180K180. It was found that with increasing fertilizer application rate, the yield of dry raw materials increased. The most favorable conditions for growth and development of plants of St. John's wort developed in the variant with the maximum rate of fertilizer application - N180P180K180, where the yield of dry raw materials in the first year was 3,31 t / ha, and in the second year – 4,15 t / ha, which exceeded the reference result (without fertilizers) by 0,61 t / ha and 0,84 t / ha, respectively.
Prospects for international integrated research of the carbon cycle in the system "soil-plant-atmosphere"
Authors: Tarariko Yu. O. , Lukashuk V. P.
Published: July 2021

Ukraine is located about at the latitude of France, the northern part of the United States and southern Canada and has similar to these countries natural conditions. Different in terms of soil and climate conditions, the regions of agriculture in Ukraine can be considered as analogues of similar natural conditions of agricultural areas in other parts of the world. Soils with a high carbon content are more productive and able to better filter and purify water. Water contained in the soil serves as a moisture source for 90% of world agricultural production. One of the main areas of research is the study of the ratios of main products and by-products of yield, as well as root and plant residues when having different soil fertility and using promising varieties and hybrids of crops.  The use of optical express methods should be carried out according to the stages of organogenesis of field crops, which will enable to specify the relationships between them, to develop criteria and indicators for effective regulation of nitrogen and carbon cycle in the system "soil - plant - atmosphere", to develop models of formation and transformation of root and other plant residues taking into account changing agrometeorological factors, crop rotations, features of the branch structure of agricultural production, varieties and hybrids of field crops. In the future, this will enable to determine the areas in the selection aimed at accumulating root mass and achieving garanteed deficit-free balance of organic carbon in the soil. The research will enable to purposefully and effectively regulate the cycle of carbon and nitrogen, both at the level of individual agricultural production systems and on the scale of the same type of agricultural areas and regions, taking into account the whole set of variables, including features of the sectoral structure of production, climate change, etc.

Relevance of research. In the area of ​​irrigated agriculture, one of the most difficult as to developing flooding processes is the area of ​​terrace drift within the ancient delta of the Lower Dnieper in Kherson region. The terrace area is located on a flat area within a large drainless bowl about 40 km long and up to 5-10 km wide. On the surface of the bowl there are large drainless depressions (Chornyanske, Novomayatske, Podokalynivske, Tarasivske) and many small ones.

The purpose of the work is to establish the patterns of developing flooding processes and substantiate a system of reliable protection of the territory against that in difficult natural and water conditions.

Methods and objects of research. The research was conducted at the research and production site located near Tarasivka village, Oleshkiv district, Kherson region. The results of the research were based on the data of reconnaissance surveys, long-term observations on the depths of the groundwater table (GWT), precipitation, space images, etc. In addition, it was assumed that the area is considered to be flooded if the depth of the GWT exceeds the critical limit, which for the study region is defined as 2 m.

Research results and main conclusions. In modern conditions, part of the village and adjacent lands are subject to constant groundwater flooding and periodically  surface water flooding. In the central part of the village, groundwater depths exceed the critically acceptable depth, which for the study region is defined as 2 m. The water and ecological situation in the village is significantly exacerbated in wet periods. Current development of flooding within the terrace requires the development and implementation of a more effective protection system. One of the important options for protecting the village territory is the construction of a horizontal drainage system, which is set up in the village and its surroundings. The depth of drainage is 3.0-3.2 m. The runoff is discharged into the North-Crimean Canal by means of a pressure pipeline. The surface drainage system should be represented by a network of trays and ditches arranged in the streets of the village and a collector, which provides self-flowing of excess water into an artificial reservoir - pond. Options for the reconstruction of the NCC, which provide for using the drainage capacity of the canal and the construction of a regional self-flowing reservoir, were addressed. The modernization of irrigation and drainage systems and implementation of the developed proposals will significantly increase the protection level of the ancient terrace of the Dnieper River against the harmful effects of water. The decision on a proposal is made on the basis of feasibility study.
Modern aspects of scientific support for the restoration of drainage systems in the humid zone of Ukraine

Modern aspects of scientific support for the restoration (reconstruction and modernization) of drainage systems in the humid zone of Ukraine were determined, which were established based on the results of the analysis of the current state and features of drainage systems functioning. One of the priority areas is the development of a scientific justification of improving water supply for drainage systems. The most effective and economical technological method of increasing the water supply in reclaimed areas is the accumulation of local drainage runoff. Given the shortage of local drainage and surface runoff, increasing the water supply in reclaimed areas is provided by withdrawing and supplying to reclamation systems extra water volumes from existing reservoirs, rivers, ponds, lakes, located both within and beyond the systems. The current structure of agricultural use of drained lands in the humid zone is subject to both climate change and export market conditions. In agricultural production such crops as grain corn, sunflower, rapeseed, soybeans are cultivated. Changes in the use of drained land should be taken into account when justifying the reconstruction or modernization of drainage systems. This will enable to develop and implement a set of measures for technical re-equipment and reconstruction of drainage systems, introduce advanced resource-saving technology for growing economically attractive crops and ensure effective water regulation on drained land sin accordance with the requirements of agricultural production. The technical state of modern drainage systems in the humid zone is mainly characterized by two conditions: satisfactory, when the systems are under operation (operational) and can perform their functions keeping the design mode, and unsatisfactory, when the restoration of drainage systems is only possible provided modernization measures. Given climate change, the priority measures for the modernization of drainage systems should include work to expand their functionality to regulate soil water regime throughout the growing season. In view of the cost of modernization to expand the functionality of different types of systems (drainage, drainage and irrigation, polder and water circulation) by constructing irrigation systems on them is much lower compared to modernize them to drainage and irrigation ones when  using sluice technology, preference should be given namely to the construction of irrigation systems.

The article presents the results of the research on soil bulk density and permeability as well as weediness of maize crops at the beginning and end of growing season on average for 2016-2019, applying different basic tillage and fertilizer systems. The goal of the research was to determine the effect of different methods and depth of basic tillage and fertilizers on agrophysical properties of soil and crop productivity in grain-row crop rotation when irrigating in the south of Ukraine. The objective of the research was to determine the effects of different methods and depths of basic tillage as well as fertilization on the agrophysical properties of dark chestnut soil and the productivity of corn in short crop rotation. During the experiment, field, quantitative-weight, visual, laboratory, calculation-comparative, mathematical-statistical methods and generally accepted in Ukraine methods and methodical recommendations were used. The research was conducted in the research fields of the Askanian SARS IIA NAAS of Ukraine.

Based on the research results it was established that, both at the beginning and at the end of grooving season when applying the tillage up to 28-30 cm within the system of differentiated tillage bulk density was the smallest as 1,14 g/cm3 when using green manure and 1,19 g/cm3 without its use. When applying subsurface different depth tillage, bulk density increased up to 1,18 g/cm3 when using green manure and up to 1,26 g/cm3 without its use. Maximum bulk density of 1,28 g/cm3 was observed when no tillage applied without using green manure and 1,31 g/cm3 when using it that is by 12,3 and 10.1% higher compared to the reference area, respectively. The highest corn productivity was observed when applying subsurface different depth tillage, where the average values by the factor A were about 10,93 t/ha that is higher than those obtained in the reference area by 0,52 t/ha, or 5,0%. The use of zero tillage caused the obtaining of the lowest yield in the experiment as 8,71 t/ha that is less compared to the reference area by 1,7 t/ha, or 19,5%.
