The purpose of the present study is to show the usefulness of the satellite data and the data derived from unmanned aerial vehicles (UAVs) for estimating the relationship between cereal grain crop yield and the amount of nitrogen fertilizer applied. The study was conducted on the land of the Kuraginskoye Research Farm. The study material was spring barley cv. Biom. Three test plots were studied; mineral fertilizer, urea, was used in different quantities for foliar application in June; applications were performed at equal intervals. Multispectral images were based on PlanetScope satellite data, with the 3 m spatial resolution, and the data derived from the DJI Phantom 4 Multispectral UAV, with the 10 cm resolution. The satellite and UAV data were used to calculate spectral vegetation index (NDVI) (Normalized Difference Vegetation Index). A high correlation was obtained between the NDVI values calculated using satellite data and UAV data. The satellite data provided the basis for assessing barley crop yield as dependent on the amount of foliar-applied urea during the growing season. Maps of the spatial distribution of barley NDVI were constructed using the Phantom UAV data; they showed that the third foliar application of the fertilizer was not economically justified.

Published: October 2021

The study was conducted between 2018 and 2020 in the arid zone of Stavropol Territory to determine the yields of different varieties of winter wheat cultivated using direct seeding technology, based on weather and climatic changes. The work was carried out on the basis of «Agrokhleboprodukt» JSC agricultural enterprise. The precursors were sunflower, chickpea; soft winter wheat varieties - Zustrich (st.), Bagira and Bagrat. It was found that growth, development and productivity of winter wheat depended on abnormal weather-climatic conditions. It was noted that annual average rainfall tended to decrease while annual average temperature and vegetation index NDVI tended to increase. The average variation of indicators for sprouting of different varieties and precursors was 9 %. The seedlings emerged 19-20 days after sowing. The rates of variation reflected the high heterogeneity in plant development in all phases. The variation of sprouting density was homogeneous in all varieties and precursors. Reduction of the index was observed from the phase of sprouting to earing and for all the precursors. Winter wheat yields were 3.01-4.50 t/ha for sunflowers and 3.26-4.68 t/ha for chickpeas. The variety Bagrat showed the best results for chickpeas and the variety Zustrich for sunflowers.
Dependence of apple yield on soil parameters in the conditions of the north of the Central Black Earth Region
Authors: Zakharov V L , Zubkova T V
Published: October 2021

The purpose of our research was to establish the correlation between individual soil parameters and the apple yield on low-growing rootstocks. Of the studied soils the gray forest soil was distinguished by the smallest thickness of the humus horizon, while the largest was leached chernozem. The upper line of the typical chernozem carbonate site was closest to the soil surface, while on gray forest and chernozem-moist meadow soil carbonates were the deepest. The lowest bonitet score belonged to gray forest soil (bonitet class 7), the highest – to leached chernozem (bonitet class 9). Typical chernozem podzolized, meadow-chernozem, chernozem-meadow, chernozem-moist-meadow and meadow-chernozem soils belonged to the 8th class of bonitet. Only the gray forest soil was of average quality, the rest of the soils were the best. Apple varieties grafted on semi-dwarf rootstocks 62-396 give the highest yield when grown on typical chernozem, and varieties on medium-sized (54-118) and vigorous (seed) stocks - on podzolized chernozem. Of the three given rootstocks the seed rootstocks suffer the most from the proximity of groundwater, while the semi-dwarf rootstocks - the least. As the groundwater approaches the soil surface, apple yield decreases in varieties grafted on medium-sized rootstocks 54-118. This is due to the vigor of the rootstock growth. The higher the vigor of growth, the more dangerous soils become with similar groundwater levels for rootstocks. Apple seed stocks are less demanding on soil fertility than 62-396 and 54-118. With an increase in the amount of exchange bases in the soil, absorption capacity, degree of saturation with bases, total porosity and bonitet, the yield of apple varieties on stocks 62-396 and 54-118 increases. The varieties on the stock 62-396 prefer soils with close carbonates sites, and on seed ones - with a deep one.

Published: October 2021

Recently, the focus has been on the introduction of raw materials with a low glycemic index into the food industry, among which buckwheat and rice flour occupy a special place. The use of apple pomace in the bread recipe improves the organoleptic and physicochemical properties of the product. It also allows you to make adjustments to the traditional technology of bread production: to reduce the fermentation process by increasing the rate of formation of acids in the dough. The duration of the technological process for the production of bread with the addition of rice flour is increased by increasing the duration of soaking apple pomace in vegetable oil for better binding capacity in the future with rice flour and reducing the moisture content of the dough. In order to adjust the chemical composition, recipes for wheat bread were developed with a partial replacement for buckwheat and rice flour (sample No. 1 and sample No. 2, respectively) and the addition of 9.43% apple pomace. The introduced components will improve the structural and mechanical properties of the dough. The use of apple pomace and flour of cereal crops (buckwheat and rice) in the food industry makes it possible to enrich the chemical composition of bread with dietary fiber, vitamins of group B, K, mineral components (magnesium, calcium, iron, phosphorus, manganese, selenium). Vitamin B2 helps to absorb iron and, together with vitamin B1, helps to maintain the level of this trace element in the blood. From the results of the analysis of the vitamins, it follows that the finished product contains vitamins B1, B2, B5, B6 and K, which can be used for preventive nutrition. The use of food additives of plant origin in the formulation of wheat bread leads to an increase in the biological value of the product and a decrease in its calorie content.

Published: October 2021

In modern conditions, there has been a sharp drawdown of small and medium-sized businesses. The formation of the production potential of small and medium-sized businesses in the agro-industrial complex requires special attention from the state and regional authorities. The development of small and medium-sized businesses is necessary in order to create jobs, replenish the local budget and develop the economy as a whole. As practice shows, the development of entrepreneurship is not possible without the support of the state in its various manifestations. However, in 2019, in the Krasnoyarsk Territory, there is a decrease in the effectiveness of the implementation of the subprogram “Development of small and medium-sized businesses” to the medium-efficient level. There are several reasons, in particular, against the general background of a decrease in funding, the level of availability of the state support is decreasing, which serves as a deterrent to the formation of production potential in small businesses.

The EU countries, Russia and Ukraine have become participants in the global division of labor in an environment of increasing environmental requirements. In the EU, legislation provides for compliance with the conditions for a harmonious relationship between the number of animals and the size of the land plot. In Ukraine and Russia, every year the number of enterprises is decreasing, and the concentration of animals is concentrated on huge farms, whose activities do not fit into any environmental standards. In terms of the density of the conditional livestock per 1 hectare of agricultural land, in 2017 Ukraine moved to the 183rd place among the countries of the world, and Russia to the 190th place. The countries of the world are divided into those that supply raw materials – cereals and oilseeds and their processing products, and others – engaged in subsequent refinement, re-export or processing, the production of compound feed, livestock products and the export of finished products – meat, dairy products, highly productive animals, etc. In 2019, compared to 1992, grain exports in Ukraine and Russia increased by 39.5 million tons, and 39.8 million tons, respectively. As a result of the implementation of the strategy associated with the reduction of the sown areas of labor-intensive crops and the increase in the export of fodder resources, the employment of the rural population compared to 1991 decreased by more than 10 times. Russia and Ukraine are not capable at the present stage of exporting pork of meat high-performance genotypes.

Published: October 2021

Active and activated carbons are adsorbents, which are used to solve a wide range of tasks to improve the quality of drinking water, alcoholic beverages, including vodka. The traditional active coal used in distilleries in Russia is BAU-A coal, which has recently been obtained of poor quality due to the fact that not only dense wood species (birch, oak, beech) are used in the production, but also soft tree species. The study of new adsorbents showed that the best indicators for abrasion strength, micropore volume and adsorption activity are activated carbon MEX and crushed anthracite sorbent (CAS). MEX activated carbon and pine nut shell activated carbon contain less ash impurities. After filtering through the studied adsorbents in water-alcohol solutions, the mass concentration of acetic aldehyde increased (which confirms their catalytic activity); the hardness determined by calcium and magnesium cations increased to acceptable limits, which allowed to soften the taste; the optical density decreased, the oxidability increased, and the organoleptic parameters improved, which indicates the effectiveness of cleaning with the studied adsorbents. The best results were noted for water-alcohol solutions treated with activated carbon MEX and CAS.

In the conditions of market relations, the production and sale of meat, especially beef, are becoming one of the main sources of monetary income for private and collective farms in the Republic of Sakha (Yakutia). However, the technology of meat production was complicated by the limitedness of concentrated feed - previously the main productive feed, which occupied up to 20-25% in terms of nutritional value in the structure of the feed balance of cattle. Under these conditions, the traditional hay-pasture type of livestock feeding again acquires a leading role in the rearing of heavy meat young with good qualities. One of the most important issues related to the organization of industrial production is the choice of the most rational and economically sound technology arising from the specific conditions of each zone. Improving the system of planning amalgamations is one of the central issues of radical restructuring of the system of management of sectors of the national economy. One of the directions for improving planning is the development of a scientifically grounded forecast of the development of the association, and on its basis - a draft plan. Moreover, in conditions of constantly developing inter-farm relations, when due to the peculiarities of production technology. The issue of economic assessment of the efficiency of the work of not only individual links, but precisely the technological chain as a whole, is acquiring especially important national economic significance. The country’s invaluable national treasure is its domestic scientific potential. The article describes the relationship between the participating farms, on the one hand, and the established inter-farm enterprises and associations, on the other, certain economic relations arise, the relationship of cooperating farms is considered, which are aimed at creating and strengthening joint interest in the development of an inter-farm enterprise or association.

Published: October 2021

The article considers one of the key aspects of transformations taking place with modern cadastral systems in the context of globalization, integration and digitalization of the surrounding space and economy. It is revealed that the transformation of existing functions of national cadastral systems in the transition to digital economy will obviously lead to the emergence of new properties of cadastral systems, in particular to the emergence of properties of adaptability. The study shows the regular stages of development of the functions of cadastral systems for each time stage, proving that the functions performed by the cadastral system are not static; they change as the economic system of society changes. From the point of view of system conceptions, the development of cadastral system follows a logistic curve and includes the stages: emergence of cadastral system and functions, stabilization of functions, their qualitative development, specialization of functions. Each stage is accompanied by the process of function deployment (winding up) under the influence of the processes taking place in the economic system and society. The emergence of the property of adaptability in the near future of cadastral systems will contribute to the emergence and development of a whole bundle of functions of national cadastral systems, aimed at adapting these systems to the environment of their functioning. The emergence of this new feature is necessitated by the ongoing digital transformation of land-use systems as a response to the challenges facing the global land-use system.

The article considers the influence of resource-saving technologies in agricultural production during tillage. The possibilities of zero tillage in the conditions of agriculture ecologization are determined. The necessity of using soil protection technologies in connection with the use of tank mixture in the processing of the reference area is justified. The quantitative content of total organic carbon (Sorg), as well as alkaline-soluble and water-soluble organic matter, was estimated. Their share in the structure of Sorg is determined. For the first time in the agricultural zone of the Krasnoyarsk Region, the long-term effect (9-10 years) of zero technology on the dynamics of organic carbon content and its mobile forms was determined. Chemical and physico-chemical indicators relative to seasonality are presented. The degree of mobility of the organic matter of the soil treated by zero technology is determined and the reasons for this fact are revealed. It is shown that the zero technology reduces the degree of mobility of organic matter.

The study results on using macro- and micronutrients in the cultivation of white lupine (Lupinusalbus L.) in the soil and climatic conditions of the Central Black Earth region of Russia are presented. Field trials were carried out in 2018-2020 at the Department of Plant Growing, Breeding and Vegetable Growing in Belgorod State Agrarian University. The object of research is a high-intensity variety of white lupine Degas. The subject of research is the Aquamix microfertilizer of two brands – Aquamix-T (for seed treatment) and Aquamix-TV (for foliar dressing), macrofertilizers – potassium sulphate (K2SO4) and potassium monophosphate (KH2PO4). The weather conditions during the years of the experiments were unfavorable for the growth and development of lupine, since during the entire growing season of the plants an increased temperature regime was observed with a deficit of precipitation. The soil cover of the experimental field is represented by typical chernozem with an average content of basic nutrients. The accounting area of the plot is 18 m2, the replication is fourfold, the placement is systematic. The experiment included seven options: 1) control (without fertilizers), 2) seed treatment with Aquamix-T micronutrient fertilizer, 3) seed treatment with Aquamix-T micronutrient fertilizer and foliar fertilization with Aquamix-TV micronutrient fertilizer, 4) seed treatment with Aquamix-Tilist micronutrient fertilizer solution potassium sulphate, 5) seed treatment with microfertilizer Aquamix-Tilist feeding with potassium monophosphate solution, 6) seed treatment with micronutrient Aquamix-Tilist fertilizer with a mixture of Aquamix-TV + potassium sulphate, 7) seed treatment with micronutrient fertilizer Aquamix-Tilist fertilization with potassium monophosphate mixture. Analysis of the data obtained showed that the highest yield of white lupine seeds was obtained on the variants with seed treatment with Aquamix-T micronutrient fertilizer together with foliar dressing with Aquamix-TV micronutrient fertilizer in combination with K2SO4 or KH2PO4 macrofertilizers, which was 3.64 and 3.62 t/ha, respectively, which is 0.64 and 0.62 t/ha or 21.3 and 20.5% above the control variant.

Lipid oxidation is one of the leading indicators that determine the storage duration of emulsion fatty products. To protect fat and oil products from oxidative spoilage, antioxidants are widely used, the mechanism of action of which is to terminate the reaction molecular chains. As a result of the studies carried out, it was found that physical modification of protein products from sesame seeds (full-fat flour, protein concentrate), used in the production of mayonnaise as a structurant and stabilizer, by treatment with electromagnetic fields of extremely low frequencies, makes it possible to increase the resistance of the finished product to oxidation.

The research was carried out in order to establish the effect of mineral fertilizers on the nutrient’s dynamics in corn crops. The experiment was carried out from 2016 to 2018 in Zavodoukovsky district of the Tyumen region. The experimental scheme provided for the option without using mineral fertilizers and with the introduction of NPK for the planned yields from 4.0 to 6.0 t/ha of corn grain. In the experiment, a hybrid Obsky 140 was sown; the seeding rate was 70 thousand plants per hectare. It was found that the introduction of mineral fertilizers provides an increase in the content of nitrate nitrogen by 20-25 mg/kg of soil; mobile phosphorus by 9-48 mg/kg. The studies revealed that one kilogram of the active ingredient of nitrogen fertilizers increases the NO3 content in the soil by 0.17 mg/kg; a kilogram of phosphorus fertilizers in the active ingredient increases P2O5 by 0.30 mg/kg; a kilogram of potash fertilizers in the active ingredient increases K2O in the soil by 0.33 mg/kg. During the growing season of maize, the content of nitrate nitrogen, mobile phosphorus, and potassium in the soil in the control decreases to 5, 58, and 93 mg/kg, respectively. On fertilized options, the decrease in nitrate nitrogen and phosphorus is less – 12-14 and 59-69 mg/kg. Whereas potassium decreases more significantly – 69-92 mg/kg.

Published: October 2021

The purpose of the study is to identify the municipalities of the Altai region, which is one of the leading agrarian regions of Russia, with the development potential for cooperation of small forms of farming in dairy cattle breeding. It was found that in conditions of a decrease in the number of cows in all categories of management, the proportion of municipalities in the region that have the highest and high potential for the development of consumer cooperation increases (in 2007 this group included 54.0% of all municipalities of the region, then in 2020 more than 69.8%). However, this potential has not been realized, which significantly reduces the possibility of stabilizing and increasing milk production in the region. It was concluded that consumer cooperation develops only with government support and by proactive entrepreneurs. In the areas with suitable agrarian infrastructure for the pooling non-profit associations of milk producers, the necessary infrastructure, organizational and educational conditions should be developed.

Published: October 2021

The agribusiness sector has great importance in the economy, and in order to remain competitive, the number of investments in disruptive technologies and concepts, such as Internet of Things, Physical Cyber Systems, Artificial Intelligence, among others, grows. These concepts are often applied by agribusiness startups, known as Agritechs. To help these startups spread their technologies, and mitigate their high mortality level, the use of a maturity model is a good tool, as maturity models help to identify factors that need to be worked on and improved. The creation of a maturity model for Agritechs is innovative, which makes the definition of possible maturity models to be used as a basis challenging. Thus, this article seeks to present the core constructs related to Agritechs in order to identify possible maturity models that can be used as a steppingstone in creating a new maturity model, specific to Agritechs. To reach this goal, the bibliometric analysis software, SciMAT, was used, to define the most relevant themes for the area of Agritechs, so that, based on these themes, it is possible to more properly research maturity models relevant to the definition of dimensions, basis of an Agritechs maturity model. The results showed that maturity models in sustainability, industry 4.0 and startups should be combined and adapted to develop a maturity model specific for Agritechs. The initial dimensions developed for this model were: Change management dimension, Strategic dimension, Technological dimension, and Sustainability dimension.
