Abstract
This research aims to study the process of stimulation and the choice of optimal modes of seed treatment by ultrasonic exposure. Agricultural production faces providing the population with high-quality and affordable agricultural products, raw materials, and food. It is also an important task to provide livestock breeding with a full-fledged feed base. Barley is one of the high-protein cereals with 8-15% protein content in the grain. According to several scientists, field germination of barley seeds averages 65.8% [1]. In most cases, this is due to insufficient moisture during the growing season in difficult soil and climatic conditions. In most cases, this is due to insufficient moisture during the growing season in difficult soil and climatic conditions.It is necessary to conduct exploratory studies to determine the intensity of ultrasonic radiation and its duration, to determine the influence of the selected ultrasonic effect on the process of swelling and oxygen penetration into the seeds.

Published: December 2021

Abstract
Winter wheat varieties sown in the Rostov region are characterized by varying degrees of resistance to pests. The size and quality of the wheat harvest are threatened not only by weather conditions, but are reduced by various pathogens, among which yellow and dark brown spots have recently played a large role. Therefore, the aim of the research is to search for sources of resistance among varieties and samples of winter wheat to the causative agents of pyrenophora (Pyrenophora tritici-repentis) and dark brown spot (Cochliobolus sativus). Resistant varieties serve as an ideal factor inhibiting epiphytotics and improving the ecological environment in general. Disease monitoring was carried out in research and production teams of the Federal State Budgetary Scientific Institution Agrarian Research Center “Donskoy”. Laboratory research - in the laboratory of mycology and phytopathology of the All-Russian Institute for Plant Protection. The object of research is 226 varieties and samples of winter soft and durum wheat obtained from the department of selection of winter wheat of the Federal State Budgetary Scientific Institution of the ANC “Donskoy”. It was established: in laboratory conditions (VIZR), 15 varieties and samples showed high resistance to yellow spot in soft winter wheat of intensive type. In studies on resistance to dark brown spot out of 155 samples of winter soft wheat, no highly resistant ones were found.

Abstract
The article presents data on the effect of phytopathogenic fungi of the genus Fusarium on the expression of genes responsible for the synthesis of various enzymes and other protein molecules involved in the induced immunity of Triticum aestivum plants (Pathogen Resistance protein, PR - proteins). The effect of suspensions containing conidia of phytopathogenic fungi in various concentrations (104,106,108 conidia per 1 ml per 100 grams of seeds) was evaluated under the conditions of a model experiment. The data on the effect of Fusarium fungi on the morphometric parameters of winter wheat are also presented. During the work, it was found that the treatment with a conidial suspension has the greatest effect on morphometric parameters, and over time the difference with the control becomes the most noticeable; and that in the presence of fungi the expression of pathogenesis-associated protein PR-1, chitinase PR-3 and inhibitor of proteinases (PR-6) is the most active.

Abstract
The results of research on the effectiveness of the fungicide Comissar are presented, EC (active agents propiconazole, 300 g/l and tebuconazole, 200 g/l) against rice Pyricularia, in the conditions of laboratory and vegetation experiments. The experiment was conducted in 2016-2017 in the Primorsky Territory. The fungicide was used at the consumption rate of 0.3 l/ha and 0.4 l/ha one time. In the primary laboratory tests on pure culture Pyricularia oryzae a high inhibitory activity of the drug against the coastal population of rice Pyricularia was revealed. It is noticed that Comissar significantly inhibits the growth of fungal colonies in all tested concentrations. Treatment of the nutriculture medium with solutions of the drug provides a significant preventive effect on the development of P. oryzae compared to an untreated control. The effectiveness of the drug was 100% on the 7th day and 89.3-90.4% on the 14th day. It was found that the use of the drug as a fungicide for the treatment of vegetative rice plants significantly reduces the development of Pyricularia. Comissar has a high biological efficacy against the pathogen at 47.4% (0.3 l/ha) and 62.7% (0.4 l/ha). The use of the fungicide contributed to the active growth of plants and it increased the main productivity indicators: the length of the panicle by 2.08-32.17 cm, the number of filled grains by 3.0-4.5 pcs. and their mass by 0.21-0.24 g per plant, as well as the mass of 1000 grains by 4.91-5.51 g. The maximum reliable increase in grain yield by 3.77 g/vessel was obtained in the variant using a fungicide at the minimum consumption rate.

Authors: Mishchenko L , Terekhin M , Terekhin N , Muratov A 
Published: December 2021

Abstract
The meteorological conditions in which organogenesis stages take place and hydrothermal regime can determine the phenotypic manifestation of quantitative signs, such as, for example, the activity of alpha-amylase. The purpose of our work was to determine what factors (temperature, precipitation, heterothermal coefficient) affect the enzyme activity, at what time of the vegetation, and in what way this influence is evident. The analysis of weather conditions and falling number (FN) for the period from 2011 to 2020 was carried out. Analysis of the FN value over 10 years showed that it can vary from 90 s to 429 s, and at that, the nature of its change is the same, regardless of whether we are considering one variety or the average value for a group of varieties. The correlation coefficient between the FN of a group of varieties and individual FN is 0.94-0.98. Generally, during the vegetation season, the alpha-amylase activity was influenced to a greater extent by the amount of precipitation than by temperature. This dependence is negative - an increase in precipitation leads to a decrease in the FN, and, consequently, to an increase in the enzyme activity. However, it was found that in different phases of ontogeny the influence of temperature and precipitation can be diametrically opposite.

Published: December 2021

Abstract
Currently, despite of the active development of agriculture and the cultivation of many species, the use of wild food plants is relevant. Ferns also belong to such plants. Eight species of edible ferns grow in the Amur Region, of which 6 species are widespread and form large thickets. The population of the Amur Region uses 4 species for food, the most common is Pteridium japonicum, rarely –Athyrium sinense, Athyrium monomachii, Dryopteris expansa. The literature data on bracken harvesting on the territory of the Amur Region from 1970 to 2019 are presented. It was revealed that the collection takes place spontaneously and unsystematically. Irrational harvesting of raw materials leads to a decrease in yield and quality of harvested products. To restore bracken thickets after collecting, a recovery period of 4-8 years is required. Schemes for the use of fern populations are proposed, taking into account the period of their recovery. For a reasonable recommendation for the use of Athyrium sinense, Athyrium monomachii, Dryopteris expansa, Onoclea interrupta, Diplazium sibiricum in food, it is necessary to conduct research on their chemical composition, nutritional value, methods of preparation and storage.

Published: December 2021

Abstract
The morphological characteristics of the endocrine pancreas of nutria in female and male nutria at the age of 1 day, 2 months, 4.5 months, 7.5 months and 12 months have a number of sex and age characteristics and differences. The number of islets in pancreatic lobules at 1 day of age in males is 3–6, and in females – 2–3. At 2 months of age, their number in males decreases to 2–4, and in females it increases to 5–6. From 4.5 months of age, the number of islands in females and males ranges from 2 to 3. At 1 day and 2 months of age, in nutria, islet division is recorded due to the cleavage and formation of new cell groups. The area of endocrine islets in females and males of nutria changes in a wave-like manner with age, having minimum values in 1-day and 4.5 months of age, and the maximum at 12 months of age. The nuclear-cytoplasmic ratio of endocrine islet insulocytes in nutria increases from 1 day to 2 months of life to their maximum values, and in subsequent age periods decrease and by the age of 12 months reaches its minimum.

Authors: Nikolaev Nikolay 
Published: December 2021

Abstract
The article deals with the influence of technologies for carrying out transport operations in the preparation of rough feed (hay, as well as valuable varieties of straw) on their quality and efficiency indicators of the entire technological process. To improve the quality of these operations, a combined transport technology has been proposed. During its development and research, the methods of simulation modeling, experiment planning and correlation-regression analysis were used. Regression equations were obtained in the form of the Cobb-Douglas function. The proposed innovative technology for combined transport of forage has proven its effectiveness during production tests in private conditions of agricultural enterprises. Evaluation of economic efficiency through the cost of transporting one ton showed an effect of 7-15%, depending on the quantitative and brand composition of the complex. This technology makes it possible to increase the efficiency of forage procurement, which affects the efficiency of animal husbandry and food security of the country.

Abstract
The article presents the results of studies conducted on the inclusion of Presan and Selko pH feed additives produced on the basis of organic acids in the feeding diets of Ross-308 cross broiler chickens. Organic acids and their salts are used in poultry farming as an alternative to feed antibiotics, and also has the ability to prevent the development of intestinal bacterial infection, increase the resistance of the body, thereby improving the absorption of feed nutrients and increasing poultry productivity. The largest preslaughter weight was in the groups of cockerels getting the T6 diet without antibiotics adding, which is 1.92% more than the groups getting the T1-control diet. In addition, the output of the pectoral and femoral muscles was higher by chickens getting a T6 diet by 0.5 and 0.3%, in contrast to groups getting a standard diet. Thus, it has been experimentally proven that the tested feed additives Presan and Selko pH do not reduce the slaughter performance of broilers.

AbstractThe study of the taxonomic structure of the southern chernozem under influence of microbial preparations and various farming systems in the conditions of the southern steppe zone has been carried out. Metagenomic analysis of the microbiome of southern chernozem showed the presence of 174 genera representatives of prokaryotes, among which 17 are dominant, representing more than 1%. Farming systems cause changes in the taxonomic structure of the microbiome in comparison with virgin soil in the steppe zone. The influence of microbial preparations of complex action on the qualitative and quantitative composition of the microbiome of southern chernozem and increasing under no-till farming system has been established. The maximum content of water-soluble organic matter was found in virgin soil, which has higher amount of plant residues, up to 491 mg/kg of soil. Under the influence of farming systems its amount decreased in 4.2-8.5 times. The use of a complex of microbial preparations in the southern chernozem contributed to an increase in the amount of water-soluble fraction of humus depending on the farming system: 1.7 times with the conventional farming system and 3 times with no-till compared to the control without CMP.

Abstract
The purpose of the research is differentiation of valuable for breeding sunflower lines by resistance to Phoma rot. The promising constant sunflower lines were estimated by their resistance to Phoma rot using methods of artificial inoculation in the greenhouse and laboratory conditions. In greenhouse conditions, there were used two methods of artificial inoculation with a fungus Plenodomus lindquistii in the bottom of leaf petiole of a sunflower plant at a stage of the first true leaf pair. Application of the pieces of agar nutrient medium with mycelium, pycnidia and picnospores (unbroken) allowed to identify resistant and mid-resistant sunflower lines (VK 900, L 86 and L 107, L 132). At inoculation with 0.2 ml of a fungus spore suspension (concentration of 1 × 106 spores/ml), five susceptible and one very susceptible sunflower lines (L 2385, L 103, L 136, L 131, L 128, and L 82) were determined. In laboratory conditions, the quick test for estimation of susceptibility to Phoma rot (dose of infection – 12 g) allowed to reveal more than 50 % of plants with healthy root system and two constant sunflower lines L 116 and L 136 with the affection degree of one point. Estimation of susceptibility to Phoma rot infection of the different organs (stem and root system) at artificial inoculation showed a possibility to differentiate sunflower lines by resistance of roots and stems and to select the most promising for the further work in breeding.

Published: December 2021

Abstract
The need to protect the environment makes it necessary to significantly change the general approaches to environmental efficiency of production, to minimize the impact on nature at the present level of productivity and quality. Today instead of the temporary measures aimed at overcoming the effects of pollution, the long-term measures are being taken more and more often at the design and construction stages to nullify the causes of pollution in advance rather than to have its effects in the future. The processes and devices that have been previously used to collect and dispose the industrial waste are now considered a passive approach to environmental protection. The matter is that the amount of waste generated during the production process remains almost unchanged, and this does not meet the new environmental requirements. The active approach involves creating the modern low-waste and non-waste technologies that can efficiently use raw materials in production processes, as well as converting the waste into easily recyclable components that are least harmful to the environment. The article considers the conceptual principles that show the essence of the active approach to improving the industrial technologies in order to protect the environment. It is mainly focused on studying the features of recycled water supply and water purification.

Published: December 2021

Abstract
In modern complex engineering-geological conditions of cities, the growth and scale of development of dangerous natural processes and phenomena can be traced. In many ways, the reasons for this are not only technogenic load on the soil, but also changes in climatic factors. Buildings and objects exposed to hazardous factors of hydrogeological processes are becoming increasingly vulnerable to their impact, which can lead to catastrophic consequences. One of the main conditions for increasing the stability of objects is the adaptation of existing methods or approaches to assessing natural hazards that have a negative impact on the physical state of such objects. The authors of the article propose an adaptation of the international INFORM approach in order to assess the hazard level of natural processes and phenomena in built-up areas. The task is also to develop a methodology for assessing the physical state of objects exposed to such processes and phenomena. To solve this problem, the study examines the practical aspects of applying the principles of the Weber-Fechner law in determining the state of the structural parameters of buildings that are under the influence of negative factors of hazardous natural processes and phenomena. The study is based on the principle of changing the category of the physical state of objects from changes in the level of exposure to hazardous factors of natural processes and phenomena.

Published: December 2021

Abstract
The dissolved oxygen (DO) is one of the most important parameters in lakes ecosystem. Variability of DO in lakes is associated with the absorption of oxygen due to the decomposition of organic matter and chemical reactions and the release of oxygen as a result of photosynthesis. The DO concentration also depends on seasonal changes in water temperature and mixing regime. The aim of this work is to assess the influence of seasonal thermal and density stratification on the DO stratification in a small mesotrophic lake and to develop a regression DO model, with water temperature and density and characteristics of wind regime as independent variables. Long-term measurements of water temperature and DO in small Karelian Lake Vendyurskoe in 2007-2020 were used. At the stage of spring-summer heating, three periods are considered when the water column was in the state of homothermy (May 15-June 15), weak stratification (July 15-August 15), and strong stratification (July 15-August 15). The wind load (number of days with wind speed more than 3 m/s for each period) was analysed based on the weather station Petrozavodsk data. As a result of multiple regression analysis, taking into account the wind load, dependences of DO stratification on water temperature stratification (R2 = 0.51) and water density stratification (R2 = 0.61) are found. Obtained regression DO models can be used for solving various environmental tasks.
