Abstract
This article contains the results of a study on the study of foliar feeding of potatoes with liquid polymer fertilizer Zelenit nitrogen micro at concentrations of 25, 30 and 35 mg/l. The provision of the plant with the main elements of nutrition contributes to good growth, accelerating its development, and also has a positive effect on the resistance of plants to negative influences. In the course of our research, it was found that it is effective to use foliar top dressing with Zelenit at a concentration of 30 to 35 mg / l, here the plants were better leafy and had the largest number of stems, which had a positive effect on the formation of the crop. The most productive of the studied varieties was the Belarusian variety Manifest, which ultimately had the maximum yield of seed material of the first field generation, which plays a paramount role for seed production. When studying the average coefficient of adaptability (Ka) in the conditions of the Pskov region, it was found that the most productive and promising varieties for growing in this region are Manifest and Lileya Belorusskaya with the highest coefficients of adaptability from 1.25-0.02 and with the use of liquid polymer fertilizer at a concentration of 25-30 mg / l.

Published: June 2022

Abstract
The article analyzes the results of using the plant growth regulator Biosil® to increase the resistance of peach to the main leaf diseases (peach leaf curl (caused by Taphrina deformans (Berk.) Tul.) and shot-hole disease (caused by Stigmina carpophila (Lév.) M.B. Ellis)). The studies were carried out for four years (2018-2021) in peach orchards in the zone of humid subtropics of the Black Sea coast of the Caucasus (Sochi, Russia). The degree of development of peach leaf curl in the control variant was 10.2-25.0%. The degree of development of shot-hole disease in the control variant was 9.2-29.8%. The use of Biosil in combination with fungicides in half doses and in pure form makes it possible to increase the resistance of the crop to the studied diseases. The maximum biological efficiency (up to 70%) in relation to leaf curl and up to 60% in relation to shot-hole disease was observed when Biosil was used in a tank mixture with fungicides. The use of the plant growth regulator Biosil makes it possible to reduce the dose of fungicides in peach agrocenoses while protecting against peach leaf curl and shot-hole disease by half. The use of the studied growth regulator for four years did not lead to a decrease in its biological efficiency.

Published: June 2022

Abstract
Annually, there is an increase in the cost of soybean components of feedstuffs, which negatively affects the profitability of poultry farming. The use of cheaper alternative feeds in poultry diets such as rapeseed flour, as well as sunflower kernels and seeds, brings novelty to fodder production and broiler feeding. The purpose of these studies was to determine the impact of unconventional fodder ingredients on meat productivity and the development of internal organs of broilers. The results of the experiment on the use of rapeseed flour in the diets of turkeys show that its introduction into the diets reduces their pre-slaughter living weight and the weight of the ripped carcass. Development of the internal organs of the experimental groups was comparable to those of the control group. The inclusion of sunflower kernel and seeds in the diet contributed to increased meat productivity and better development of internal organs in broiler chickens. Compared to the sunflower core, broilers receiving sunflower seeds and the enzyme preparation Ronozim tended to increase the weight of internal organs, while the greatest differences were established by the relative weight of the gizzard (when using 5% of fodder ingredients - by 0.05%, and when using 7.5% - by 0.03%).

Published: June 2022

Abstract
The studies were carried out in a fruit-bearing apple orchard of an intensive type in the steppe zone. The soil is ordinary chernozem, pHKCl 5.7-5.8; humus content 4.0-4.1%. The climate is temperate continental, with warm summers and moderately cold winters. The length of the growing season ranges from 184 to 190 days. Schemes of chemical and integrated protection of the orchard are presented. The use of an integrated protection system with the inclusion of growth regulators (epin-extra, zircon), fertilizers (siliplant, ecofus, cytovit, ferovit, etc.) provided an increase in apple harvest by an average of 33-45% over 2 years. The increase in yield is associated with an increase in the effectiveness of pesticides, an increase in the resistance of the crop itself to negative environmental factors, an increase in growth processes, and a supply of nutrients. Analysis of the obtained products showed the absence of residual quantities of used pesticides. The provision of the population with fruits is associated with their supply from other countries. An analysis of imported products for their safety showed that 10-12% of the amount received contained pesticide residues above the maximum allowable level (MAL). A list of insecticides and fungicides, the residual amounts of which were found in apples above the MAL, is given.

Authors: Barsukova G N , Yurchenko K A 
Published: June 2022

Abstract
The necessity of clarifying the boundaries of the most valuable productive agricultural lands represented as grape-suitable land is justified in connection with the reduction of the area of vineyards, their withdrawal from agricultural turnover. It was established that from 1982 to 2022 in the resort-city Anapa, the area of cultivated vineyards decreased by 10968 hectares or 76%. A method of clarifying the boundaries and determining the areas of grape-growing land using satellite images and data from the “Public Cadastral Map” service is proposed. The method established in 2007 provides the exclusion of forest strips, roads, outbuildings, swamps, plots from industrial land and were transferred for expansion of settlements and the assessment of obtained areas were made by ownership forms and by types of permitted use. The proposals were tested on the example of the Agricultural Production Cooperative named after Lenin of the resort-city Anapa, it was found that in addition, 1920 hectares of vineyards can be laid in this agricultural organization.

Published: June 2022

Abstract
The article presents the results of three-year field experiments on the application of compost of liquid poultry manure on sunflower crops in the conditions of southern chernozems of the Rostov region. The application of compost increased the yield of sunflower seeds by 0.21-0.67 t/ha, the oil content of seeds - by 2.3-3.5%. It has been established that the maximum yield of sunflower seeds was in the variant with the introduction of 20 t/ha of chicken compost in autumn during plowing, which significantly exceeds the maximum dose of N75P75K75 mineral fertilizers in terms of efficiency. A positive economic effect was after application of compost of liquid chicken manure. An increase in the level of profitability in the experiment compared to the control variant (fertilization) was with an increase in the dose of chicken compost to 10 t/ha, a further increase in the dose led to a decrease in economic efficiency.

Authors: Lyubov V K , Popov A N , Mukhamedzyanova E I 
Published: June 2022

Abstract
An effective way of using plywood by-products is burning to obtain energy required in the technological cycle of the production. The PRD 22000 boiler was operated on fuel mixture consisting of crushed plywood waste, birch bark, dry and wet veneer shorts, wood sanding dust and sawdust from line of plywood cutting, sufficiently high energy and environmental performances were obtained. However, periods of the boiler operation between shutdowns for cleaning of heating surfaces were short. Studies have shown that crushed plywood waste is the strongest contaminant of combusted fuel mixture since of its ash contains a very high amount of CaO, Na2O, K2O which cause the incrustation on heating surfaces. Wood sanding dust and sawdust from line of plywood cutting, which contain particles of abrasive material and binder resins used to fix it on sanding belts, as well as particles of glue used in the production of plywood occupy the second position in terms of pollution level. The exclusion of these components from combusted fuel mixture allows to multiply periods of boiler operation between shutdowns for cleaning of heating surfaces in six times.
Territory management based on the arrangement of agricultural landscapes
Authors: Nedikova E V 
Published: June 2022

Abstract
Currently, there is degradation of land, ignoring the system of scientifically based crop rotations, all this creates enormous damage to the productive potential of the country’s land fund. The paper presents a mechanism for making managerial decisions to preserve land productivity and sustainability of agricultural landscapes, which consists in collecting reliable information about the state of land, then assessing the quality state and land use. Management decisions to preserve land productivity and sustainability of agricultural landscapes are divided into different levels: operational, tactical, strategic). It is necessary to manage the territories based on the rational organization and arrangement of the territory of each specific land use, or, in other words, the management of the territories should be based on the solution of environmental and economic issues in the process of land management, and this, of course, affects the state of the ecosystem of a particular agricultural landscape. The developed mechanism for managing territories based on the arrangement of an agrolandscape consists of 3 stages: creating an agrolandscape structure, assessing its territory and analyzing options for optimizing the territory of each agricultural enterprise located on the territory. agrolandscape could be both collapsing and highly resilient. Different specific gravity of arable land can either soften or exacerbate the ecological state of agrolandscapes in different ways, which means that with the help of optimization indicators of various types of agrolandscapes, humanity has the opportunity to influence the stability of the territory. This system of formation of sustainable land use of agricultural organizations has already been worked out in the development of projects in the base farms of the Voronezh region and is a reliable basis for managing territories.

Published: June 2022

Abstract
The article shows the results of studying the influence of soil moisture, cellulose-decomposing activity of microorganisms and the amount of nutrients on the productivity of barley in crop rotations and monocrops in Orenburg region. The purpose of the experiment is to identify the effect of moisture, cellulosolytic activity of soil and macronutrients (nitrates, phosphorus, potassium) on increase of barley productivity in crop rotations and during its continuous growing. The following research methods are used: field, thermostatic-weight, application-weight, ionometric and method of Machigin. In average for 2002-2021 studies, it is observed that the yield of fodder and energy units of barley increases up to 2.10, 1.63 and 1.24, 0.96 t/ha on a fertilized background of nutrition in the second and fourth variants of the experiment. The yield of feed units increases due to the use of productive moisture by the plant during the growing season in the mount of 32.3, 32.2 mm nitrates - 4.20, 1.91 mg, phosphorus - 1.76, 0.50 and potassium - 2.47, 1.01 mg/100 g of soil with cellulose-destroying activity of microorganisms - 7.93 and 10.37%. For other variants of the experiment, various indicators of the studied factors and barley productivity are registered. The influence of moisture, activity of microorganisms, nutrients on increase of barley productivity due to influence of millet and peas in crop rotations after the application of mineral fertilizers was revealed. The dependence of the yield of energy fodder units of barley in a crop rotation with millet on the content of used nitrates in the arable soil layer has been established. The results of the study are of great importance for agronomy in the steppe zone of the Southern Urals.

Environmental effects of agricultural activity on the Crimean Peninsula
Authors: Nekrich A S 
Published: June 2022

Abstract
The article deals with agricultural loads occurring on the Crimean Peninsula. It was determined that distribution of agricultural lands shows a strong asymmetry in this region. At least ⅔ of the whole area is characterized by essential loads on the environment due to intensive agriculture development. Given the fact that the majority of agri-business and concentration of agricultural production can be found on territories with unfavourable natural features, it is getting obvious that the negative natural processes will rapidly accelerate and loads will increase. The study is focused on revealing the geographical distribution of environmental violations caused by agricultural activity. It is considered that variety of consequences caused by intensity of agricultural loads is strongly rooted with landscape features. It was found that the distribution of the contemporary agricultural loads reflects the ways of agrarian developed on the studied territory.
The impact of various factors on the population dynamics of Epipactis atrorubens (Hoffm. ex Bernh.) Bess. in the Middle Volga region
Authors: Fardeeva M B 
Published: June 2022

AbstractLong-term population dynamics, age and spatial patterns of Epipactis atrorubens (Hoffm. ex Bernh.) Bess. are identified in the Middle Volga region in the period from 1990 to 2017. The Population dynamics were mostly of a fluctuating type, there has been a marked reduction in its number, and also a Spatial and age structure disruption due to various factors. The E. atrorubens base spectrum is centered 0.5: 8.5: 55: 36 (j:im:v:g). The dependence of E. atrorubens on temperature (r = −0.55-0.62) and positive – on precipitation and air humidity was noted, especially for pregenerative individuals (r = 0.35-0.65). Landslides and erosion caused by anthropogenic and climatic factors cause irreversible degradation of biotopes.

Authors: Montile A A , Tishkina E A 
Published: June 2022

AbstractThe article is devoted to the study of the spatio-temporal structure ofAcer negundoL. in the forest parks of Yekaterinburg on the basis of population and organism indicators. Eight fragments of ash-leaved maple cenopopulations in the Uktussky and Southwestern forest parks were examined. For the first time, a quantitative characteristic of the manifestation of organismal indicators in each ontogenetic state of maple was obtained. A feature of the spatial structure of the habitats of Acer negundo is its active introduction into cenoses in the forest parks of Ekaterinburg. An identical expansion of the species in the studied forest parks was established, however, there are also distinctive features of its habitat. In the course of the analysis of variance, the dependence of the dimensional parameters of the maple crown on changes in two factors (forest park, ontogenetic state) and their interaction was shown. The ability of the species to successfully adapt in fragmented and urbanized areas affected by recreational impacts and other forms of pollution and survive in a wide range of environmental conditions has been established.

Published: June 2022

Abstract
Operation principles of cryogenic supply systems for power HTS systems have been examined. Two non-flow (autonomous) cryogenic supply systems have been described. Gas circuit of cryorefrigerator uses neon, rather than helium, what makes it possible to decrease several-fold the number of compression stages in compressors and losses of working fluid in the circuit when leakage occurs. The use of turbomachines and gas bearings allows for substantially increasing an overhaul period of cryorefrigerator (over 30 000 h).

When laying high-protein crops, the self-preservation method turned out to be ineffective.
Experimental study of heat transfer in tube-type radiator of hybrid cooling tower
Authors: Kharkov V V , Madyshev I N , Kuznetsov M G , Nikolaev A N 
Published: June 2022

Abstract
A hybrid cooling tower is a combined evaporative and dry cooling tower. The authors developed the hybrid cooling tower with inclined corrugated contact elements and the tube-type radiator for cooling the circulating water of industrial plants. The work aims to study heat transfer in the radiator of the cooling tower experimentally. It was found that an increase in the mass flow rate of cooled water in the radiator in the range of (6.43–37.84)10−3 kg/s leads to an increase in the ratio of the amount of heat transferred through the radiator wall to the amount of heat transferred in the evaporation part of the cooling tower by an average of 9.82 times. On the other hand, an increase in the average velocity of cooling air in the range of 1.73–4.09 m/s leads to a decrease in the proportion of heat transferred through the tube wall to the amount of heat transferred in the evaporation part of the cooling tower by an average of 1.55 times.
