Published: February 2023

Abstract
The article discusses the issues of improving the planning of land reclamation activities in rice irrigation systems due to the increasing shortage of water resources. Rice is the most important crop in ensuring Russia’s food security. The modern stage of rice production involves large expenditures of resources, including water. The main “tool” of rice production is rice irrigation systems. Optimization of rice production should be based on taking into account the factors and parameters of rice cultivation, the best practices of leading rice-growing countries and the level of scientific and technological progress. The main difficulty of developing new resource-saving technologies lies in the balanced management of available resources. Such management is possible only when taking into account all the connections and relationships of factors and parameters that affect the final result - yield. Therefore, to solve the problem of obtaining guaranteed rice yields, it is necessary to solve equations with a number of constraints and several objective functions. The solution of such issues requires a progressive and multilevel approach using statistical analysis of the available monitoring data, using a mathematical apparatus implemented in a simulation-optimization mathematical model. Therefore, the presented studies are relevant, and their solution will strengthen Russia’s food security. The main and major task of resource allocation is to reduce the cost of agro-reclamation activities. The achievement of this task is implemented by the developed ecological-adaptive methodology, including optimization of land reclamation measures, taking into account the uncertainty of the initial information to ensure the effectiveness of management decisions on the rice irrigation system. This approach will allow employees of the agro-industrial complex to make management decisions in a timely manner, receive guaranteed yields of high-quality rice grains, and rice crops rotation.

Authors: Kobulova B B , Tashpulatov Y Sh 
Published: February 2023

Abstract
The most complete state of the aquatic ecosystem can be assessed by the composition of communities of aquatic organisms. The intensive supply of nutrients reduces the diversity and productivity of water bodies and increases the production of a limited number of species. In this article, the ecological state of the lake and its influence on the abundance and biomass of the phytoplankton composition of this lake are carried out. In the study of the shallow Lake Hadicha, a massive vegetation of the cyanobacterium Spirulina tenuissima Kütz was found. Large reserves of raw spirulina biomass in summer make it possible to use the lake as a source of valuable biological raw materials. Suburban reservoirs perform an important function of the regulator of the water regime of landscapes, they largely maintain its balance and redistribute moisture. At the same time, suburban water bodies are characterized by a high level of vulnerability, not only in case of excessive use of water resources, but also in the development of the adjacent territory.
Interaction of the fluid film with the oncoming steam flow in the thermosiphon transport zone
Authors: Yuldashov A A , Dustova D Kh , Duskarayev A N , Rustamov E T 
Published: February 2023

Abstract
If the liquid film flows from the wall of the channel down and the core of the flow consists of one wind mixture of steam and small liquid drops, then this is called the flow mode of the steam-water mixture. In this case, a one-phase flow theory can be used, which provides the easiest way to study two-phase flows. Steam is a mixture of water, perceived as a quasicontinuum, for which the average properties of the flow are determined. The liquid film reacts with the approaching flow in the opposite direction of the phases with high humidification on their surfaces. In this case, external and internal problems of the flow of the hydrogen vapor mixture along the wall of the channel and the flow of the film will be considered. They can be expressed through the movement of velocities and phases on the surface of the film due to the increase in the interference between them.

Authors: Tokarev K E , Lebed N I 
Published: February 2023

Abstract
The problem of recognizing the state and visualization of problem areas of crops in precision farming includes agrobiological, optical-spectral, mathematical-algorithmic and other aspects. The difficulties arising in the process of analyzing and classifying images of remote monitoring of crops necessitate the development and adaptation of methods of their computer analysis using neural network algorithms. The results of the study showed that the most effective approach to image classification is a combination of preprocessing methods followed by recognition by neural network algorithms for the rapid identification of defective areas of various nature.
Modes of operation of network pumps with shielded asynchronous motors in small irrigation systems with artificial pressure
Authors: Chernykh A G 
Published: February 2023

Abstract
The paper proposes a scheme and describes the operating modes of pumping equipment for a finely dispersed irrigation system with artificial pressure for the operating ranges of the performance of sprinklers in terms of flow. For the accepted ratio, which determines the kinetic energy of a drop per unit area, the law of drop motion in air under the action of gravity is obtained. The above network diagram in the process of regulation provides water supply for irrigation, taking into account the measured values of the sprinkler performance over time. Regulation using a centrifugal pump with a shielded asynchronous motor of the current values of water flow in the distribution pipeline connected to the sprinkler provides the technical possibility of implementing the mode corresponding to the inverted (turbine) mode of operation of the pump. The transfer of the engine to the generator mode of operation, allows you to get an autonomous three-phase source of electrical energy for the system’s own needs.

Published: February 2023

Abstract
The efficiency of vegetable production in closed ground structures is directly dependent on the costs associated with creating artificial, controlled conditions for growing plants during the period when cultivation of them in open ground due to climatic conditions is impossible. One of the indicators of the economic efficiency of vegetable production in protected soil structures is labor costs and funds per 1 hundredweight, per 100 rubles of gross production, as well as energy costs, including thermal energy. Usually, solar, biological, electric and other types of heating are used to supply thermal energy to cultivation facilities, each of which has its own disadvantages. The bio-vegetation complexes structurally distinguished by the fact that cultivation beds are located on various foundations make it possible to create an active underground heating system. The paper presents the development of a design for an active subsurface system for thermal energy supply to the bio-vegetation complex and calculations of the main parameters of the system for autonomous operation of the object at negative outside air temperatures. The design of the active subsurface system for thermal energy supply to the bio-vegetation complex is proposed in the form of a heat-accumulating sand-gravel mass, inside of which there are heat supply circuits with a heat carrier closed with a concrete screed on top. The calculation of energy consumed by the active sub-ground thermal system providing optimal parameters of the growing medium corresponding to biological rhythms of plant development at low outside air temperatures is also presented. The study determines the area of the photovoltaic unit and the number of photovoltaic modules for generating electric energy in order to cover the spent thermal energy and the effective functioning of the active subsurface system for thermal energy supply to the bio-vegetation complex.
Ozone pest control of grain

Abstract
Grain insect pests impact adversely on the agrarian industry. Insects make a significant portion of crops to become unusable. During storage, lacking proper monitoring and control, different pests tend to grow in grains. In the laboratory conditions, grain cereal heaps are most often infested by grain weevils and flour beetles. Since pests are growing very rapidly, it is necessary to immediately apply pest control actions. Ozonation can effectively destroy a large proportion of insects. However, the recommended ozone concentrations for disinfection are excessive and very hazardous for humans. Therefore, lower ozone concentrations should be applied for treatment. To this end, concentrations of ozone ranging from 1.4 to 5 mg/m3 with an exposure interval of 5 hours is found to be sufficient to completely exterminate the grain weevil. It is very difficult to maintain a constant dose of the used gas mixture, so one should focus on the concentration of ozone above 1.0 g·min/m3. To completely exterminate the flour beetle, it is necessary to ozonize under the given conditions for more than 8 hours. In this situation, the ozone concentration should surpass 1.8 g·min/m3. Ozonation is carried out until the death of 40… 50% of insects, the remaining part dies over the next day.

Published: February 2023

Abstract
The successful development of the HoReCa segment, which is intensively developing in the Russian Federation, requires continuous innovations to ensure high demand for the goods and services offered by them. The promotion of healthy nutrition seems quite relevant. Now it has become necessary not only to cook deliciously and quickly, but also to show that the products meet the requirements of healthy nutrition. In this regard, producers seek various methods to increase the nutritional value of traditional foods. A promising direction is the introduction of unconventional vegetable raw materials into the formulations, which contain a high content of certain essential food components. The paper proposes to replace part of wheat flour in such bakery products with gram flour as an enriching ingredient. This first of all will improve the biological value of the protein in finished products. To optimize the recipe components, various indicators were studied during dough fermentation, and quality indicators of the finished products were also determined in accordance with regulatory documents. The obtained innovative products were characterized by increased biological value, high quality and organoleptic properties. The technological documentation was developed for such bakery products with increased nutritional value.

Abstract
This article presents the results of studying the dynamics of the nutritive regime for leached black soil during the vegetation period of apple trees depending on the dosage and application times of compound fertilizers, as well as combinations of organic and mineral fertilizers. We detected a positive influence of fertilizers on the accumulation of liable forms of nitrogen, phosphorus, and potassium in the soil of the fruit orchard. The highest average content of ammonia absorbed during vegetation was observed in section N180P180K180 – 40.6 mg/kg, which was 10.4 mg/kg higher than in the unfertilized ref-erence section. The content of nitrates in the reference section was 8.9 mg/kg of the soil. The application of N60P60K60 increased their content by 2.3 mg/kg (25.8%), N90P90K90 - by 3.1 mg/kg (34.8%), N120P120K120 - by 4.8 mg/kg (53.9%). The application of mineral fertilizers at various rates had a significant impact on the content of liable phosphorus in the 0-40 cm layer of soil: its average content per vegetation period was 101.8 mg/kg of the soil for section N60P60K60 and 129,1 mg/kg for section N150P150K150. The content dynamics for exchangeable potassium in the fruit orchard soil was at the maximum at the beginning of the vegetation period and the minimum during fruit formation. Later on, the content increased during the harvesting stage but it was lower than the original level. The highest average content of exchange-able potassium per vegetation period was observed in section N150P150K150 – 184 mg/kg, which was 44 mg/kg higher than in the reference section. Out of the two sections treated with manure, the Manure 20 t/ha+N30P70 (with NPK reaching up to 120 kg/ha) section was deemed more efficient. The content of exchangeable potassium in it exceeded the reference section by 41 mg/kg.

Abstract
The paper considers land and water resources use and quality of return flow and its re-use for irrigation of salt tolerant crops in conditions of the Republic of Karakalpakstan. The article considers land and water resources use and quality of return water and its reuse for irrigation of salt-tolerant crops in the Republic of Karakalpakstan. The volume of the return (collector) flow and its quality in the Republic entirely depend on water availability, i.e. water availability in the Amu Darya River. In high-water years, such as 1992, 2005, 2010 and 2017, the return flow volume reached 3.0 billion m3, which constituted 35-38% of the total water withdrawal used for crop irrigation. In high-water years, almost 65% of the total water withdrawal has a salinity of 3.0 g/l, which is quite suitable for some food crops. Under conditions of fresh water deficit in the Republic of Karakalpakstan, multi-year (2000-2018) experimental-production research on collector-drainage water use for irrigation of salt-resistant forage, vegetable-gourd crops, pasture-hayfields, as well as for liman irrigation of wild forage crops (reed and others), was conducted. Based on the findings of the research, the article offers practical and scientific recommendations for solving these problems.

Published: February 2023

Abstract
Geoinformation systems (GIS), regime and technological software complexes (RTSC), Outage Management System (OMS), Computer-Aided Engineering (CAE), Supervisory Control And Data Acquisition (SCADA), automated information and measurement systems of power control and accounting (AIMS ECA) and other systems are widely used in the electric-power engineering. All systems have different ways of representation, storage, transformation of information and solve different problems, but initially use the description of the same objects of rural electric networks. A rural electric networks object is described as a set of graphical and semantic information. The information systems duplicate the information about the rural electric networks objects. Thus, the relevance of integration of information systems is obvious. The article considers representation of initial information about rural electric networks objects; variants and expressions describing the integration; application of exchange formats. The solution to integration problems lies in applying a universal format for exchanging the same type of data between different applications. All applications must support the Common Information Model (CIM). CIM is an object-oriented data description using XML terminology and methods. This model will solve the issue of integrating applications from different vendors and ensuring the independence of application users from its developer.
Comparative evaluation of the photosynthetic photonic efficiency of white LEDs

Published: February 2023

AbstractWhite LEDs are an effective solution for light culture due to the presence of the green emission spectrum, which has a positive effect on growing plants in the artificial environment. However, the assessment of the effectiveness of the application of the white LEDs for photoculture is complicated by the lack of information in the technical documentation for LEDs about their photosynthetic photon flux in the range of photosynthetically active radiation. In this regard, the purpose was to measure the photonic and energy characteristics of popular white LEDs in various operating modes and to evaluate their photosynthetic photonic efficiency. High-demand brands of LEDs of the rated power of 0.5W in SMD2835 and SMD3030 housing were selected to be studied. The luminous flux of LEDs was measured using a luminous flux meter using the “integrating sphere” method, and then their luminous efficiency and photosynthetic photonic efficiency were calculated. The highest photosynthetic radiation efficiency (more than 2.7 μmol s−1) was registered for LEDs of the color temperature of 4000K and 5000K in the SMD3030 housing, manufactured using flip-chip technology. LEDs of the color temperature of less than 3000K have the lowest photosynthetic photonic efficiency, which is primarily associated with the energy losses in the phosphor and the presence of radiation in the far-red spectrum region, which is not included in the region of photosynthetically active radiation. White LEDs can be used both separately and in combination with the red and blue LEDs, which will allow selecting the spectral composition of the radiation for the specific species and variety of plants.
Energy-saving installation for heating and cooling livestock premises using geothermal energy
Authors: Trunov S S , Tikhomirov D A , Khimenko A V , Kuzmichev A V 
Published: February 2023

Abstract
The article considers the calculation of the main design parameters of a geothermal air cooling system in livestock premises, which, unlike traditional systems, do not use fossil fuels to generate heat. They simply take energy from the soil, while, as a rule, electricity is used only for the operation of fans, compressors and pumps. The purpose of the study is to reduce energy consumption when creating the technologically necessary temperature and humidity conditions in premises by using the cold of the earth’s strata. The calculation of the heat exchanger installed inside the livestock premises is reduced to the choice of design and energy parameters of the surface heat exchanger of the cooling unit, as well as to the determination of the flow rate of water passing through the heat exchanger. Water cooling is done in a heat exchanger buried vertically in the soil (the so-called probe). The probe is a plastic pipe lowered into the well and filled with a special filling with good thermal conductivity. The article presents the calculation of the probe length, since this parameter of the heat exchanger-probe is the main parameter of the installation.
Justification of the traction resistance of the coulter of the onion planter for ecological production of products

Published: February 2023

Abstract
Modern agricultural technologies of onion cultivation should follow high requirements for their planting. The construction of the onion planter coulter determines the quality of planting. The authors designed the drill coulter for sowing onions, which qualitatively prepares the planting furrow by leveling and compacting the surface of the furrow bottom. The use of skid coulters allows to hold them on a single row, that, including protection against damage during leveling and compaction of the furrow bottom in a single row unit, reduces the metal consumption of the coulter and increases its compactness. When determining the parameters of the coulter, considering the condition of stability of its movement when planting onion row units, a theoretical substantiation of the traction resistance was carried out. When determining the parameters of the coulter, taking into account the conditions of stability of its movement when planting the onion-sowing, a theoretical justification of the traction resistance was performed, with the possibility of regulating the pressure force of the coulter on the soil with a row spacing of 0.20 m, for the range of the speed of the sowing 3.6 …5.4 km / h, the depth of the coulter 30…50 mm when planting the onion-sowing. The design of the coulter and its theoretical justification are proposed, which makes it possible to reduce the traction resistance, as a result of which the emission of exhaust gases into the atmosphere is reduced. As a result of the uniform distribution of nutrition over the area and the uniformity of onion shoots, weeds are decline, which reduces the use of herbicides, and therefore increases the environmental friendliness of the products produced.
