The paper considers an experimental scarifier of legume seeds, which makes it possible to scarify the seeds of legumes, thereby increasing their germination. The article describes the theoretical basis for the movement of seeds along a conical surface, considers the method of discrete elements, which underlies the Rocky DEM software package, which allows modeling complex systems of models. Laboratory studies were carried out, during which the angle of repose was determined for two varieties of alfalfa seeds (Sarga and Vega) and eastern goat’s rue seeds. On the basis of the obtained modeling data, an experimental scarifier with a scarifying working unit was constructed and production experiments were carried out, during which the quality of processing and germination of seeds of oriental goat’s rue on the experimental scarifier were determined.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135828512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, only 12% of Russian regions (the leading group) are fully included in the innovation agenda. It is rather difficult to strategize innovative changes within a large country, since the regions are largely differentiated in the context of social and economic development, innovative activity, and the state of scientific and technological potential. The ability of each region to designate its own “window of opportunity” in priority activities, taking into account the imperatives of neo-industrial development, is especially in demand, as it will make innovation processes more manageable. This is especially important in the context of the tightening of sanctions restrictions and the actualization of the request to achieve sustainable technological sovereignty of Russia. The goal of decomposition of the factors of innovative development of ROPS implemented in the study is, in fact, a key preparatory stage for an integrated approach to the subsequent development of regional innovation strategies. The three-level hierarchization of factors and their substantiation by subject areas in the methodological aspect is universal both for local ROPS and for regional control systems. A detailed study of the indicated factors is the starting point for positioning the innovative profile of the ROPS and directly affects the effectiveness of the implementation of innovative scenarios in industries and the agro-industrial complex. The formation of a comprehensive understanding of the innovation situation in the regions contributes to focusing efforts on stimulating the innovation activity of the ROPS, taking into account regional specifics, which fully corresponds to the goal-setting of the Concept of Technological Development of Russia until 2030, which is scheduled to be approved this year. In the next three years, the state will allocate about 4 billion rubles to subsidize innovative technological entrepreneurship. 11 federal development institutions and 46 regional corporations of regional and interregional profile are involved in active support of the innovative development of the ROPS.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135894902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microplants with well-developed shoots and roots were planted in a mixture of peat and perlite (1:1) and grown at illumination of 2–3 klx, photoperiod duration of 16 h, temperature of 24 ± 2°C, air humidity of 70%. The frequency of adaptation of microplants, depending on the number of subcultivations, varied slightly and amounted to 83...100%. On the 60th day of adaptation, the length of the shoot was significantly higher by 21...28% in microplants after 8 subcultivations (206.73 mm) compared with 14, 15 and 16 passages. There were no differences in the length of additional shoots depending on the amount of subculturing. According to the number of nodes on the main shoot, a tendency to their decrease with an increase in the number of passages was observed. A significant increase in the content of chlorophyll a with an increase in the number of subcultivations on the 14th day of adaptation was revealed, however, later these differences leveled out. On average, the in vitro viability index for passages was 1.45 and increased up to 30 days of adaptation to 1.75. The revealed features of changes in morphometric and physiological parameters indicate a good adaptive ability of the analyzed plants, while micropropagation in vitro during 16 subcultivations did not significantly reduce their adaptive potential.

The study was conducted to assess the development of the agro-industrial complex and measures to stimulate its investment activity. The largest area of the agro-industrial complex is agriculture, the sustainable development of which is a priority for the state to ensure the country’s food security. Thanks to state support, the agro-industrial complex is demonstrating steady growth. However, problems remain in the industry, the solution of which will strengthen the role and quality of the main directions of the state agrarian policy of the country. Creating a favorable investment climate in the agro-industrial complex is an effective way to develop the industries included in its structure. Measures to stimulate investment activity include: modernization and replacement of production facilities; provision of preferential terms for lending and leasing for participants in the agro-industrial complex; tax incentives; grant support for agricultural producers, agricultural consumer cooperatives, peasants, farms, individual entrepreneurs producing agricultural products; creation of agro-industrial parks. The practice of applying the unified agricultural tax for 2011-2021 in Russia, including in the context of federal districts, showed that, despite the reduction in the number of those applying this taxation regime, there is an increase in the amount of tax calculated. For the development of the agro-industrial complex, it is necessary to introduce non-financial instruments of state support.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135828504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When implementing it, it is not necessary to completely crumble the surface layer of the soil, but only to break up its clods, which is achieved by introducing a spring into the design of the ploughshare. During translational movement, a force arises directed in the opposite direction, which compresses the spring. When the force acting on the ploughshare decreases, it expands, and when it increases, it contracts. The resulting vibrations are transmitted to the soil clods and, with sufficient force, their destruction occurs. Vibrations of the share lead to a change in its kinetic energy. Instantaneous energy increases and decreases, while the average energy remains constant. More complete information about the interaction of the ploughshare with the surface layer can be obtained through mathematical modeling. The purpose of the study is to determine the compression coefficient of the spring. The simulation is based on solving Lagrange equations of the second type in the Cartesian coordinate system with initial and boundary conditions determined by the design of the ploughshare. When compiling a mathematical model, the following were taken into account: – the gravity of the ploughshare; – gravity of the soil layer; – the elastic force of the spring, which creates additional vibrations; – cutting force of the soil layer; – the friction force of the soil layer on the surface of the ploughshare, – the normal reaction of the supporting surface of the ploughshare and the angle of its entry into the surface layer. Modeling made it possible to determine changes in the instantaneous value of kinetic energy, which ranges from 0 to 3.6 J. The optimal amplitude of oscillation of the share during forward motion at a speed of 6 km/h was 0.02 m. The spring stiffness coefficient for loamy soils of the Ryazan region should be in the range of 2200…3000 N/m.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135828508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It includes knowledge, skills, production experience, patents, databases, software, trademarks used in the activities of economic entities. Intellectual capital, first of all, is inherent in knowledge-intensive activities, in which a significant place belongs to the activities of universities. Despite the unfavorable geopolitical situation, universities in our country remain participants in Russian and international rankings, based primarily on data on their intellectual capital. At the same time, not only its financial, but also its image component depends on the place of a university in the ranking. In this regard, objective disclosure of information about the intellectual capital of universities becomes an urgent task. The formation of ratings is currently carried out under conditions of presentation of incomparable data, which is explained by the lack of an adequate information base for their formation. In this regard, in the presented study, the management accounting system of universities is positioned as an information base for preparing information about their intellectual capital. It is proposed to include the block “University Intellectual Capital” in the management accounting framework of Russian universities, which accumulates information about its components - human, client and organizational capital. The study substantiates a system of indicators to be included in this block both at the stage of formation of university management accounting and during its subsequent development. Adding the “University Intellectual Capital” block to the university management accounting system will not only increase the reliability of information about the university’s intellectual capital, but will also ensure greater objectivity in conducting rating assessments of their activities. In addition, this solution will allow reformatting existing information flows of universities, avoiding their repeated duplication.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135828691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work was carried out in 2020-2022 in the Republic of Mordovia. The scheme of the experiment provided for the study of the following options: basic application of mineral fertilizers (factor A): without fertilizers (0), N30P30K30, N60P60K60, N90P90K90; foliar top dressing with liquid complex fertilizers (factor B): without top dressing (0), housing 2 l/ha, housing 4 l/ha, housing 6 l/ha. The soil of the experimental site is alluvial medium humus (5.5 %), slightly acidic (pHKCl 5.3), in the arable layer was characterized by an average content of mobile (Kirsanov method, GOST 54650.) phosphorus (91 mg/kg) and manganese (53.7 mg/kg), high – potassium (170 mg/kg), zinc (1.6 mg/kg) and boron (1.9 mg/kg). During the growing season, the best weather conditions were in 2020 and 2022, and 2021 was less favorable for the growth and development of plants. The application of mineral fertilizers on average for three years increased the productive bushiness of plants by 0.38...0.66 pcs./rast. (by 19.0...33.0 %), the number of grains in the ear by 1.1...2.6 pcs. (by 6.8...16.0 %), grain weight per ear by 0.08...0.15 g (by 13.1...24.6 %), barley yield by 0.46...0.77 t/ha (by 15.3...25.7 %). The best parameters of the crop structure and grain yield are noted in the N60P60K60 variant. A further increase in the level of mineral nutrition to N90P90K90 did not lead to a significant change in the studied indicators. Non-root fertilizing of plants of the housing and communal services “Agris” of “AzotKaliy” brand did not have a significant impact on the productive bushiness of plants. Its introduction at a dose of 4 l/ha provided an increase in the number of grains in the ear by 7.3...12.8%, the weight of grain from the ear by 0.08...0.11 g (by 12.7...17.5 %), the yield of barley by 0.37...0.50 t/ha (by 11.7...15.9 %). A further increase in the dose of LCU to 6 l/ha did not lead to a significant change in the studied indicators.
