The object of the study was the municipal districts of Kirov region. Study period is 2011-2021 The study was carried out by analyzing the time series of crop yields with the allocation of the ecological component of its variability. To unite objects into classes, the method of pair-group association was used. As a result, 7 agroecologically similar territories were allocated to accommodate crops. The most favorable for the placement of barley crops is agroecologically similar territories 2, which is located in the central agro-climatic zone. Here, the maximum yield of barley (23.5 c/ha) is obtained with a minimum level of variation (16.5%). The cumulative influence of soil and climatic conditions provides a guaranteed crop yield in this area. The soil cover of agroecologically similar territories 1 and 3 is mainly represented by soddy-podzolic and podzolic soils with a high degree of cultivation. Moderate moisture and heat supply in these areas favor the cultivation of barley with a moderate level of variability (17.7-18.8%). In these agroecologically similar territories, the productivity of barley to a greater extent depends on the level of agricultural technology. The combined effect of soil and climatic conditions ensures moderate yields in agroecologically similar territories 5 and 7 with a high level of variation (22.0-24.1%). Therefore, in these territories, in order to obtain a guaranteed yield, it is recommended to use barley varieties that are more adaptive to local conditions. Excessive moisture in agroecologically similar territories 4 and 6 limits the production of high and stable yields. In these territories, the minimum yields are obtained (14.3 and 15.6 c/ha) with a high level of variation (26.8 and 24.6%).

As the methodological base of the study, general scientific methods, works of domestic and foreign scientists on crop production and products of its processing were used. The article considers tools for improving resource support as elements of the organizational and economic mechanism for the development of the industry. Tools for improving the resource support of crop production are an integral part of the organizational and economic mechanism and should be aimed at creating conditions for the reproduction process in the industry and import substitution of certain types of resources. The proposed tools are organized by groups corresponding to subsystems of the crop industry: technological, economic, social, environmental, organizational. The developed forecast for the development of the crop industry and the proposed measures of the organizational and economic mechanism were assessed by calculating structural shifts. Structural shifts make it possible to estimate the efficiency of shifts in the actual and predicted structure. The calculation of the shift efficiency indicates that the structure of commodity production in the forecast year within the forecast confidence interval will not change significantly, which indicates that the structure of crop production is balanced. The projected growth of crop production within the confidence interval will affect the growth of the industry's profitability by only 0.99% to 57.15%. Profitability growth is projected due to an increase in the share of oilseeds and a reduction in the share of other crop products in the structure of marketable products.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":"304 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":"135828685","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}

In the existing methods for assessing the erosion resistance of soils, the kinetic and potential energy of the water flow is studied. It is believed that the decrease in total energy in the process of flowing along the channel is associated with the work of the water flow in destroying and washing away the soil. However, this does not take into account the energy of capillary waves existing on the water surface during laminar flow. The frequency of the capillary waves is usually such that the waves are not visible to the naked eye and are therefore not taken into account, although their energy is, in order of magnitude, comparable to the energy of the flow. Refinement of the value of erosion resistance is associated with the ability to evaluate and take into account the energy of capillary waves. The work is related to the development of a methodology for accounting and evaluating the contribution of the energy of capillary waves to the total energy of a water microflow, which has a destructive and eroding effect on the soil of a sloping agricultural landscape. The paper developed a mathematical model for estimating the energy of capillary waves, on the basis of which an expression was obtained to determine the ratio of the energy of capillary waves formed on the surface of a water flow to the kinetic energy of the water flow. To experimentally study the process of development of capillary waves on smooth and rough surfaces and determine the operating parameters, an installation was created in the form of a rectangular-section tray with an adjustable inclination angle, adjustable intensity of water supply and replaceable working surfaces. The geometry of the microflow and the shape of its surface were determined from the results of video filming and the readings of the laser rangefinder. In the range of regime parameters studied in this work, the numerical estimation of the dependence of the energy of capillary waves on the kinetic energy of the water flow for the first time revealed a significant (up to 40–60%) contribution of capillary waves formed on the surface of microflows to the total energy of the water flow. The results obtained in this work indicate the need to take into account the contribution of capillary waves in the energy analysis of the initial stage of water erosion on slopes.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":"96 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":"135828690","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 searching for suitable enclosing structures for installing photovoltaic modules, the geometry and spatial orientation of buildings, their relative placement, and shading effects are taken into account. The purpose of the study is to develop a criterion for identifying prohibited and permitted areas of the territory of an agricultural complex for the installation of photovoltaic modules. By eliminating areas with uneven lighting conditions, the photovoltaic installation can operate at maximum efficiency. Prohibited areas for the installation of photovoltaic system modules can be considered those that are shaded during a typical summer day, as well as during the peak intensity of solar radiation on all characteristic days of the year. Permitted areas for the installation of photovoltaic system modules can be considered those that are illuminated during every day of the year. The remaining areas must either be excluded from the installation plan for photovoltaic system modules, or various methods must be used to reduce the impact of module shading on their efficiency (installation of bypass diodes, the use of various module connection schemes, etc.). Using the example of the territory of an existing agricultural processing enterprise, the possibility of installing modules on the roofs of industrial buildings was analyzed, taking into account changes in the illumination of the receiving surface of the building roof slopes for peak intensity during characteristic days of the year.

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.

Data on providing the dairy cattle breeding industry with breeding material (bull semen, breeding stock) show that the cattle breeding industry is largely dependent on import supplies. Thus, the share of imported breeding stock in the domestic market for 2021 in the Russian Federation amounted to 36.3%. An analysis of breeding business development on the example of the Republic showed that 47 certified breeding farms operate on the territory of the Republic. In total, these farms keep a little more than 183 thousand heads of cattle, of which more than 150 thousand heads, or 82%, are identified as breeding. In 2021, the breeding farms of the Republic sold livestock products (milk, offspring) in the amount of 11,693 million rubles. Not all breeding farms perform their main function - the cultivation and sale of breeding stock. So, in 2021, out of 47 breeding farms, 25 did not sell breeding stock, which means that they grow breeding stock only to meet their own needs, and not for sale. The remaining 22 breeding farms had about 2% of the proceeds from the sale of breeding young animals, while, in advanced farms, it reaches 28% of the total cash proceeds of cattle breeding, which shows a low level of raising commercial breeding young animals in the breeding farms of the republic. Of the 43 municipal districts of the republic, in 26 as of 2022, there were no breeding farms, which indicates a low provision of municipal districts of the republic with breeding farms. In these municipal areas, the average productivity of the dairy herd for 2017-2021. amounted to 4857 kg of milk, with an average productivity of cows in the republic of 5521 kg. The exception is the Aktanyshsky municipal district, where the average productivity was 6395 kg. About 60% of breeding farms operate on the territory of 5 municipal districts of the republic, in which the average productivity of cows over 5 years ranged from 7503 kg to over 8618 kg of milk per year.

Regression analysis of the dependence of the productivity of cows on the provision of breeding and farms in municipal areas shows a significant dependence of the productivity of cows in productivity groups, ranging from 4162-5275 kg to the productivity group over 8618 kg, on the provision of their breeding farms.
