The effect of agrotechnical methods on productivity of new winter wheat varieties on ordinary blackearth

The current study was conducted in the pre-Azov agricultural area of the Rostov region in the stationary trial of the FSBSI FRARC in 2020–2023. The purpose of the study was to establish the effect of elements of cultivation technology methods, such as methods of basic tillage, seed sowing rates and a level of mineral nutrition on productivity of new winter wheat varieties in the conditions of ordinary blackearth in the Rostov region. The objects of the study were two new winter wheat varieties ‘Bylina Dona’ and ‘Akapella’ developed in the FSBSI FRARC. The scheme of the trial included three factors for each variety. The experiment was repeated three times. When conducting the study, there was used the generally accepted methodology of a field trial. The effect of different rates of mineral fertilizers and seed sowing with different methods of basic tillage affected the grain productivity of new winter wheat varieties. As a result of three-year study, there has been found a positive effect of moldboard plowing and a seeding rate of 5 million pcs./ha against the background of N120Р80К80 kg/ha of active substance for both varieties, which provided the best productivity of 6.66–7.02 t/ha. There has been established a tendency for changes in productivity of new winter wheat varieties under the effect of the studied elements of agricultural technology, for which there have been identified individual factors and calculated the mean productivity independently of the other two factors, taking into account the experimental options for each of them. The largest mean grain productivity of the winter wheat varieties ‘Bylina Dona’ and ‘Akapella’ with 5.77 and 6.05 t/ha, respectively, was provided by the highest level of mineral nutrition, with a norm of N120Р80К80 kg/ha of active substance, which made it possible to improve productivity by 48.3–49.4 % compared to the control without fertilizers. There has been determined an optimal background of mineral nutrition N80Р60К60 kg/ha of active substance, which ensured the maximum feedback of grain due to fertilizers. The variety ‘Akapella’ in all experimental variants produced grain on 4.5–5.1 % higher than that of the variety ‘Bylina Dona’.

Winter barley productivity in the southern part of the Rostov region when sowing sunflower as a forecrop with different seeding rates

The current study was conducted in the southern part of the Rostov region in the agrotechnical crop rotation of the laboratory for cultivation technology of grain and row crops of the FSBSI Agricultural Research Center “Donskoy” in 2021–2023. The purpose of the study was to determine the effect of seeding rates on productivity of various winter barley varieties sown after sunflower. The conducted study allowed identifying the response of winter barley varieties to different seeding rates. The winter barley variety ‘Marusya’ on average over the years of research formed the mean maximum grain productivity of 6.43 t/ha when sowing with the lowest seeding rate (3 million pcs. of germ. grains per 1 ha). For the varieties ‘Vivat’ and ‘Foks 1’, the optimal seeding rate was 4 million pcs. of germ. seeds per 1 ha, and the obtained productivity was 6.31 and 5.81 t/ha, respectively. The response of the studied winter barley varieties to seeding rates was different through the years, but the effect of this factor was 4.6–10.5 %. Reliable differences in the experiment were obtained only for the variety ‘Vivat’ for all seeding rates. The winter barley productivity was determined by the choice of a variety, and the effect of this factor ranged from 32.5 to 78.1 %. There was determined that when sowing with the lowest seeding rate (3 million pcs. of germ. grains per 1 ha), all winter barley varieties in the trial had the largest number of grains per ear and grain weight per ear with 36.3–43.2 g and 1.62–2.10 g, respectively. There was established that in the variant with this seeding rate, the varieties formed a heavy, large-size grain (nature weight of 637–660 g/l) with ‘1000-grain weight’ of 42.1–43.8 g and 10.8 to 11.3 % of protein in grain. There has been established an economic efficiency of cultivating the varieties ‘Vivat’, ‘Marusya’ and ‘Foks 1’ when sowing them with the lowest seeding rate of 3 million pcs. of germ. grains per 1 ha. With a low cost price of produced grain (5405–6136 rubles/t), in this variant of trial, the varieties obtained the maximum conditional net income (34378–45499 rubles/ha) and production profitability (108–147%).

Physicochemical properties of grain of promising winter durum wheat varieties and lines in the south of the Rostov region

The most important thing in the production of durum wheat is to obtain high-quality grain. In this regard, in the Rostov Region, there has been studied the physical and chemical properties of this crop and identified several sources for high-quality grain breeding. The objects of study were 30 winter durum wheat varieties and lines of our own breeding, with the standard variety ‘Kristella’. Large grain (1000-grain weight over 40 g) was formed by 12 winter durum wheat samples. According to the GOST, 26 varieties and lines (770–809 g/l) belonged to the 1st class of grain. In 2021–2023, grain hardness varied from 69 % to 93 %. This trait was influenced by weather conditions during the years of study, grain with large hardness (100 %) was formed in the favorable 2022, in 2023 the grain was floury (51 %). The protein percentage in grain varied over the years from 13.70% in 2022 to 14.91 % in 2021. The mean gluten content of winter durum wheat samples was consistently high over the years and ranged from 28.0 % (2022) to 30.1 % (2021). The mean carotenoid content over the years varied significantly from 472 μg/% (2023) to 718 μg/% (2021). There were significant fluctuations among the samples. Due to the diversity of weather conditions during the years of study, there have been identified 6 winter durum wheat varieties and lines ‘Diona’, ‘Dinas’, ‘Pridonie’, ‘691/20’, ‘390/20’, ‘1377/20’ according to the complex of physical and chemical properties.

Combining ability of new maize lines according to grain productivity and its components

The most important indicator of the initial material’s value in breeding for heterosis is its combining ability. The purpose of the current work was to study the combining ability of new self-pollinated maize lines according to grain productivity and its main components. The study was conducted at the FSBSI “ARC “Donskoy”, located in the southern part of the Rostov region with unstable moisture, in 2021–2023. The objects of the studies were 9 new constant self-pollinated maize lines and the line ‘RD 329’, used as a standard. The objects of the studies were also 3 testers, simple maize hybrids ‘Kros 1’, ‘Kros 2’, ‘Kros 3’ and 30 new test-cross hybrids of maize. There have been identified new highly heterotic maize hybrids of practical interest ‘Kros1×Sl 303’ (5.05 t/ha), ‘Kros1×Sl 308’ (4.75 t/ha), ‘Kros1×Sl 309’ (4.84 t/ha). There have been identified new self-pollinated lines ‘Sl 303’ (gi = 0.56), ‘Sl 308’ (gi = 0.43) and ‘Sl 309’ (gi = 0.47) with high combining ability according to the trait ‘grain productivity’ and are recommended for use in programs of hybridization. Self-pollinated lines with high GCA according to grain productivity, as a rule, had higher GCA for such productivity traits as ‘a number of grains per ear’, ‘one ear weight’ and ‘a number of ears per plant’. This contributed to the formation of a large number of grains per ear in test-cross maize hybrids (623–655 pcs.), the formation of ears with a large weight (131–147 g), and the absence of sterile plants in dry conditions. The combining ability according to the trait ‘1000-grain weight’ had no effect on productivity of test-cross hybrids in dry conditions. The use of self-pollinated lines with high values of productivity traits and transmitting high values to hybrids made it possible to develop new productive hybrid combinations.

Developing Statistical Thinking in Schoolchildren: From Theory to Practice

Since 2022, the school course «Probability and Statistics» has been taught as a compulsory subject in all schools in Russia, and questions on it are included in the Unified State Exam. However, international experience in teaching the basics of statistics shows that this is not an easy task. It includes not only teaching students how to prove the theorems of mathematical statistics and explain the calculation of the median and variance, but also contributes to the development of statistical thinking in them – the ability to make decisions based on the analysis of empirical data. According to the authors, the statistical community cannot and should not replace teachers who promote the teaching of statistics at school, but it has the opportunity to make a significant contribution to this process.The article presents the experience of the All-Russian School competition on statistics «Trend», the All-Russian teacher competition for the best practices in teaching statistics «We train the best!», with the support of the territorial bodies of state statistics in St. Petersburg, Kirov and Rostov regions; master classes for hundreds of teachers teaching statistics in grades 7–11. In addition, the article presents plans for organizing a competition on civil statistics aimed at developing skills in working with statistical data, as well as teaching the basics of statistical analysis, the use of visualization tools, and the formation of citizenship through familiarity with objective statistical information

The influence of climatic factors on the effect of growth regulators in agrocenoses of spring barley

Relevance. In recent years, under the conditions of climate change, there has been a tendency to reduce the acreage of spring barley, reduce the quantity and quality of grain. From the point of view of ensuring the stability of gross grain harvests and ecology, it is necessary to manage the agrocenosis.Methods. The experiments were conducted in 2021–2024 agricultural years in the conditions of the Azov sea zone of the Rostov region. Objects of research: Leon spring barley variety and growth regulators “Artafit” (0.3 l/ha), “Biodux” (3 ml/ha), “Obereg” (60 ml/ha), “Trainer” (3 l/ha), “Fulvohumate” (0.4 l/ha).Results. The climatic conditions in 2024 were extreme in terms of low rainfall and high amounts of spring temperatures. The year 2023 was the most favorable from this point of view. The yield level correlates with the level of moisture in the spring period, the highest indicators were observed in 2023, and the lowest in 2024. In the current market conditions and annual price increases, unit production costs are increasing. Thus, in 2024, the cultivation of spring barley turned out to be unprofitable. Moreover, the use of biological products did not allow us to gain a plus. In 2022 and 2023, the use of the drug “Trainer” turned out to be unprofitable due to the high cost of the drug. “Biodux” and “Obereg” showed the highest profitability.

Index of development of transport infrastructure as a factor of sustainable development of the coastal zone of the Sea of Azov, Russia

As a zone of interaction between land and sea, coastal zones are becoming a strategic area for achieving a sustainable expansion of economic space. The object of study is the coastal zone of the Sea of Azov (Rostov Region and Krasnodar Territory). The subject of the study is an assessment of the dynamics of transport infrastructure development index as a factor in the sustainable development of the coastal zone of the Sea of Azov.Methodological approaches to assessing the sustainable development of the territory were based on a methodology based on methods of system analysis, mathematical modeling, and GIS technologies. An indicator has been formulated that considers the area of the territory, the population, the length of public roads of local importance, the shipment of goods of local production, the work and services performed on their own, in order to measure the ‘economic’ load on the transport infrastructure.The analysis of the state of the transport infrastructure of the regions of the coastal zone for the period from 2015 to 2021 was carried out. Based on an analysis of the transport infrastructure index, it was concluded that the attraction of municipalities to the Rostov agglomeration, together with the strengthening of social, trade and infrastructure contacts with megacities will lead to a further increase in the anthropogenic load on the territory. The areas studied of the Krasnodar Territory belong to the Northern Economic Zone – a territory with a diversified economy, characterised by cross‐border links with neighboring regions.Highways are the most important link in the transport and logistics system. The level of development and the technical condition of the road network have a significant and diverse impact on the economic and social development of both the state as a whole and it individual regions.

Economic and biological assessment of a new medium-ripened variety of soft winter wheat Priazovye

Relevance. In the Russian Federation, winter common wheat is the main food and strategic crop. Permanent improvement of productivity and quality of wheat grain, reducing its production costs is the main task of agricultural production. To solve this problem, the leading place is given to the continuous and constant creation and introduction into production of new competitive wheat varieties, highly adapted to stress factors, with guaranteed high yields and high grain quality.Methods. The research was carried out in the southern zone of the Rostov region at the experimental sites of the Federal State Budgetary Scientific Institution ANTS “Donskoy” in 2021–2023 in order to create a new variety of soft winter wheat capable of forming not only high yields, but also having high frost resistance, drought resistance, resistance to leaf diseases, possessing high rheological and technological properties of grain and flour.Results. The winter common wheat variety Priazovie was developed by stepwise hybridization using the varieties Voyazh and Tanya. This is a highly productive variety. On average, over three years (2021–2023) of study in the competitive variety testing, the productivity of the variety laid in green manure fallow was 9.88 t/ha, exceeding that of the standard variety by 1.56 t/ha. The variety is capable of producing high yields after various forecrops. The maximum productivity of the variety (12.23 t/ha) was obtained in green manure fallow in 2022. The variety forms a high stem capacity (up to 800 pcs/m²), and is characterized by high resistance to the main leaf diseases, such as powdery mildew, brown and yellow mildew, loose smut, leaf blotch, etc. According to the main indicators of grain and flour quality, it belongs to valuable wheat, in terms of frost resistance (73.3%) it surpasses the standard Ermak variety (69.2%).

Влияние минеральных удобрений на содержание микроэлементов в агрочерноземе при использовании технологии No-till

The article presents the results of studies on the effect of mineral fertilizers on the content of Zn, Cu in the soil and winter wheat plants using the No-till technology. In the field experiment, ammonium nitrate (N12P52) and potassium magnesium oxide (K32Mg12S20) were applied during sowing against the background of two additional fertilizing with ammonium nitrate (N34) - N30 at the tillering stage, N70 - at the tube emergence stage. Low content of mobile Zn and Cu compounds was found in the agrochernozem of the southern zone of the Rostov region. The application of ammonium nitrate, ammophos, potassium magnesium oxide does not replenish the reserves of biomicroelements in the soil. The balance of Zn and Cu for all experimental variants was negative: Zn - 115–154 g/ha; Cu - 39.0–56.0 g/ha. The obtained results indicate a violation of the microelement cycle in winter wheat agrocenoses and prove the need to use micronutrient fertilizers to obtain stable grain yields of good quality. Keywords: AGROCHERNOZEM, ZINC, COPPER, WINTER WHEAT, FERTILIZERS, NO-TILL TECHNOLOGY

Nosological Pattern of Diseases Accompanied by Chronic Cough in Dogs

Introduction. A practicing veterinarian usually faces difficulties in both diagnosing and treating coughing in dogs. The unsolved problem in diagnosing entails doubts in the efficacy of the prescribed therapy. This is especially relevant for small dog breeds of middle and old age that often suffer from the chronic respiratory diseases and mitral insufficiency due to endocardiosis, and each of these diseases can lead to chronic cough. The aim of the research is to reveal the nosological pattern of the diseases accompanied by chronic cough in dogs.Materials and Methods. The research was based on the analysis of the medical records of 145 dogs with chronic cough that have attended to the network of veterinary clinics “Vita” (Rostov region) in the period from September 1, 2021 to July 31, 2024. The research was carried out using the following equipment: Karl Storz video bronchoscope (PAL colour system, working channel 2.3 mm, gaze direction 0°, aperture angle 120°, up/down deviation 180°/100°, depth of field 3–50 mm, working length 61 cm, outer diameter 6.2 mm); premium ultrasound scanner with improved image quality on the ZST+Mindray Vetus 9 platform; Maxivet 400 veterinary X-ray digital DR system; Poli-Spectrum–8/B computerassisted electrocardiograph; automatic hematology analyzer Idexx ProCyte Dx; automatic biochemistry analyzer Idexx Catalyst One; digital microscope Celestron.Results. The conducted research allowed us to find out the main causes of coughing in dogs. The most common cause of chronic cough found in these animals was chronic bronchitis, including that occurring simultaneously with the collapse of the upper respiratory tract. The rarest revealed cause of chronic cough was endocardiosis.Discussion and Conclusion. Coughing in dogs is not a characteristic sign of endocardiosis: even when the disease was clinically evident, coughing was observed only in the cases of lung congestion and interstitial pulmonary edema. As a rule, dogs with endocardiosis that have a pronounced loud cough intensifying after exertion, have a concomitant disease of the upper respiratory tract. Coughing in dogs with endocardiosis and upper respiratory tract lesion does not go away upon getting merely a specific endocardiosis treatment.

Causes and Diagnostic Significance of Coughing in Dogs with Endocardiosis

Introduction. Endocardiosis is the most widespread acquired cardiac disease in small dog breeds, characterised by the valvular degeneration leading to mitral insufficiency. Progression of mitral regurgitation leads to cardiac remodeling, increased left ventricular filling pressures, pulmonary hypertension and, eventually, myocardial dysfunction. Decreased exercise tolerance, dyspnea, anorexia, and coughing are the most often reported signs in dogs with endocardiosis. Coughing is often reported as the primary clinical sign of congestive heart failure in dogs with endocardiosis. The concomitant respiratory tract disease and compression of the left mainstem bronchus by the giant left atrium have also been suggested as the potential causes of coughing in these patients. However, the absence of relief from cough in dogs with endocardiosis when treated with calcium sensitizers and the registered improvement in systolic cardiac function makes doubtful the cardiogenic nature of coughing in endocardiosis. In other words, the clinical and diagnostic significance of coughing in dogs with endocardiosis has not been sufficiently studied. The aim of the present research is to determine the frequency of cough incidence in dogs with endocardiosis and to establish the pathognomonic nature of this symptom in endocardiosis, its clinical significance.Materials and Methods. The medical records of 49 dogs that have attended to the veterinary clinics of the “Vita” network (Rostov region) for cardiological examination in the period from September 1, 2021 to July 31, 2024 were analysed. The research was carried out using the following equipment: premium ultrasound scanner with improved image quality on the ZST+ Mindray Vetus 9 platform, Maxivet 400 veterinary X-ray digital DR system, and Poli-Spectrum–8/V computerassisted electrocardiograph.Results. The research allowed us to find out the following: although the cardiomegaly and the increase in the size of the left ventricle in endocardiosis can aggravate and intensify the clinical manifestation of coughing in dogs with degenerative diseases of the upper respiratory tract, they are not the necessary condition for the occurrence of coughing. Coughing in dogs with endocardiosis should be considered as a clinical sign of the concomitant inflammatory or degenerative disease of the upper respiratory tract, which should be taken into account in therapy and in the attempt to improve the quality of life of these animals.Discussion and Conclusion. We have found that only 57% of the dogs with clinically evident endocardiosis suffer from coughing, whereas it does not have the uniform nature. In dogs with cardiogenic pulmonary edema, a cough is not loud, is usually acute and is associated with the flow of fluid into the medium and large-sized bronchi. The chronic loud, hoarse cough, intensifying in the morning, is typical for dogs with endocardiosis and chronic bronchitis: these animals at the same time have the non-specific inflammatory lesion of the bronchial tree and lesion of the mitral valves. Most severe coughing, with the characteristic loud sound, is observed in dogs suffering from the elements of the upper respiratory tract collapse and cardiomegaly due to endocardiosis.

Formation of the Industrial Police on the Territory of the Donetsk Coal-Mining Basin (Pre-Soviet Period)

Introduction. Development of the industrial production in the regions becomes possible on condition of attracting the labour resources and creating the appropriate socio-economic conditions, acceptable living, training and leisure opportunities for employees. Solving these tasks results in formation of the industrial clusters and development of the settlements with the city-forming industrial enterprises. The settlements that have emerged as an evidence of the technological progress and as a result of formation of the economic relationships differ from the settlements and cities formed under the dominating influence of the agricultural and commercial sectors. First of all, the differences refer to the intensity of migration flows, quick emergence of the agglomerations consisting of the class-homogeneous labour collectives represented by the proletariat (including the stratum of engineers and craftsmen). For this reason, during formation of the industrial sector in the Russian Empire in the second half of the XIX century, a special kind of internal affairs authorities called the “industrial police” had evolved, which were partly funded at the expense of the extrabudgetary funds of the served enterprises. These practices had spread throughout the Donetsk coal-mining basin, which included an immense territory from the city of Shakhty, Rostov region (former Aleksandrovsk-Grushevskii, Province of the Don Cossack Host) – in the east to the city of Donetsk, Donetsk People's Republic (former Yuzovka, Yekaterinoslav province) – in the west. Nowadays, a scientific study of the industrial police formation process on the territory of Donbass is relevant and especially valuable due to the fact that from 2022 the coal-mining basin has become an integral part of the Russian Federation and because it possesses the vast historical and industrial-production experience of joint development and cooperation of its constituent regions, including in the field of law enforcement activities. Therefore, the paper targets to investigate the process of formation of the industrial police on the territory of the Donetsk coal-mining basin (at the pre–Soviet period).Materials and Methods. The objects of the study were the legal relations referring to the formation and development of the industrial police on the territory of the Donetsk coal-mining basin in the second half of the XIX – early XX centuries. The study was carried out based on the empirical analysis of the history of the law enforcement authorities on the territory of the Donetsk coal-mining basin. While preparing the article, the principle of historicism was applied, historicallegal, dogmatic legal and system-structural methods of scientific research were used. Along with the specific scientific methods of jurisprudence knowledge, the general scientific methods of synthesis, induction and deduction, as well as the comparative, systemic and cognitive methods were used.Results. A scientific concept of the Donbass law enforcement system, which had existed at the turn of the XIX– XX centuries within the Province of the Don Cossack Host and had represented a specific subject of the Russian Empire in the pre-Soviet period, was formed. The regulatory legal acts, which had been the basis for the emergence and development of the industrial police, ensuring protection of the public order and safety, were identified and studied. The historically justified key dates of the Donbass industrial police formation were distinguished and might be used in the moral, psychological and memorial work, demonstrating the unity of the population living on the territory of the Donetsk coalmining basin in the past and future.Discussion and Conclusion. Enforcement of the law is an important part of the law enforcement function of the state and is being ensured across the whole territory of the Russian Federation, including the “new regions” of Russia, which had been previously detached from it in 1991 due to undoing the USSR. Therefore, the research in the historical and legal development of the industrial police of the Donetsk coal-mining basin demonstrates the historical unity of the peoples of Donbass throughout the single state. The conclusions drawn by the authors upon the conducted research directly refer to ensuring the national ideological security of the Russian Federation.

Социальная тревога российского студенчества: территориальный аспект

Relevance. The article is focused оn the analysis of social anxiety and social phobia of modern Russian students of six regions of the Russian Federation in the context of a Special Military Operation and the sanctions pressure of the collective West on our state and its citizens. Research problem. The purpose of our research is to study the manifestations of social anxiety and sociоphobia caused by military actions among Russian students as a special socio-demographic group of people of the younger generation exposed to social risks. Methods. The total number of respondents was 991 people. All respondents are students of higher educational institutions. The research methodology is the Questionnaire of social anxiety and sociobia (OSTiSF). The article analyzes the data of psychological testing (face-to-face and online) of the large-scale interregional socio-psychological study “Russian students: assessments and patterns of the present and future as a basis for the formation of civic and value attitudes”. Research results. It was determined that the dominant type of social anxiety is post-situational rumination. The highest level of social anxiety was observed among young people living in the new Russian territories. Respondents from the newly annexed territories of the Russian Federation have a statistically higher level of social anxiety and sociоphobia than respondents from Belgorod and the Rostov region. Also, social anxiety is higher in women than in men. Conclusions. Psychological correction of social anxiety and sociophobia among modern youth is an important sphere of implementation of university youth policy. Its solution is the prerogative of specialised units of university psychological services.

Юрий Жданов – гений места (genius loci): Ростова, Дона и Северного Кавказа

The article highlights the main events of the Rostov period of the life and work of the outstanding organizer of science, socio-political figure and scientist I.A. Zhdanov in the context of the concept of the “genius of the place”. The analysis made it possible to identify, using the example of his biography, common objective and subjective factors, the combination of which makes it possible to transform the individual activity of the genius of the place into positive effects of the city of Rostov-on-Don, the Rostov region, and the North Caucasus region. The key positions of understanding Zhdanov's personality as the genius of the place are considered: regional ideological identification, contribution to the development of the territory, socio-cultural identity, historical reconstruction of the main events. It is shown how the scientific and social activities of Yu.A. Zhdanov contributed to the process of changes in the local Don and North Caucasian communities. An attempt was made to correlate the substantive aspects of the works of the genius of the place and his biography with the basic, fundamental elements of the history and culture of the Don and the North Caucasus. Data collection was carried out through the analysis of scientific periodicals, media materials and publications on social networks, memories of residents and representatives of regional authorities, as well as personal observations of the author.

Территориальное общественное самоуправление: новый взгляд на возможности и перспективы влияния на создание городской среды

The article considers the institution of territorial public self-government as a form of direct implementation by the population of local self-government in the administrative-territorial framework of the Rostov region as a whole and the municipalities included in it, in particular. Territorial public self-government currently has the makings for a new round of active development, both in the changing system of Russian local self-government as one of the hierarchical levels of its organization, and in the field of the urban environment, in which it acts as an important actor of change, as well as a tool in consolidating and implementing these changes.

Влияние биологических и гуминовых препаратов на динамику подвижных форм азота в черноземе обыкновенном при возделывании нута

The results of a field experiment to study the influence of biological preparations on the dynamics of mobile forms of nitrogen in 2021-2023 are presented. The tests were carried out in the conditions of the Rostov region, on ordinary carbonate chernozems. The experimental design included bacterial (“Planriz”, “Geostim”) and humic (“BIO-Don 10”, potassium humate) preparations, as well as different nutrition levels (without fertilizers and azofoska 250 kg/ha). Mineral nitrogen is characterized by high mobility; data on hydrothermal conditions and the dynamics of ammonium and nitrate nitrogen by year and nutrition level are presented. It has been established that the use of humic preparations stimulates plant nutrition, which is expressed in negative dynamics compared to the control; this effect is enhanced by the combined use of bacterial and humic preparations. As a result, an increase in yield up to 28.0 % compared to the control and up to 24.9 % compared to the background.

Трансформация гражданственности студенчества в «переломное время» (на материалах фокус-групп и эссе студентов вузов Ростовской области в 2022 и 2024 гг.)

The article analyzes the opinions and civil positions of students of the Rostov region universities in the context of a Special Military Operation and a destructive ideological war of the collective West against the Russian Federation. Based on the materials of the focus group and essays of the Don students in October – November 2022 (8 groups) and in April 2024 (6 groups, 203 essays), the life-forming factors of student youth are described: life, peace, humanism, family and immediate environment, collectivism and mutual assistance, historical memory, small homeland, patriotism. The events and factors that influenced the moral and social state of the Don students are identified: confrontation with existential problems of war and peace, life and death; uncertainty of the future in the context of the inevitability of a Special Military Operation, cultural isolation of Russia, geopolitical risks and transformation of the world order. In the face of an existential choice, there is a rethinking of the value of family, an increase in the role of the immediate circle and small homeland. A targeted state policy of memory, glorification and memorization of the Special Military Operation participants creates the ground for an increase in the role of historical memory, the values of patriotism and citizenship, trust in the authorities and approval of political decisions. The perception of Western values becomes more critical; the severity of anxiety about the cultural, economic, political isolation of Russia is erased. The hypothesis about the existence of two models of citizenship of Russian students was confirmed: a) the first (civic consciousness as public-state patriotism) is associated with factors of sociocentrism, where there is an identity with one's family, ethnic group, small homeland, and civic identity with the Russian state is strengthened, associated with a sense of duty, responsibility and obligation to it; b) the second (global citizenship) is based on the principles of anthropocentrism with guarantees of observance of constitutional rights and freedoms, humanistic values and global citizenship, but without the individual's obligations to the state.
