Published: December 2022

Abstract
The specific of the agrarian sector in the general system of the state manifests itself in relief in solving the problems of land and property relations. In the context of increasing intensity of land use there are processes that lead to a decrease in the efficiency of land use. In this regard the problem of sustainable development, organization of rational use and protection of land resources is particularly relevant. Large areas of land especially for agricultural purposes have been used for non-agricultural activities in recent years. This is of particular concern since the area of fertile land is very limited. The article discusses the main strategic directions in the field of land use in which decisions are needed which in the future will contribute to the sustainable development of not only agro-industrial production, but also rural areas in general. The role of the components of the land management system as interrelated links in the process of regulating land relations is revealed. The purpose of this research is to improve the theory and practice of the development of land and property relations in agriculture and rural areas. Research methods used in writing this work are methods of logical and comparative analysis, observation, systematic approach, review of information

Published: December 2022

Abstract
The purpose of the research is to provide for solving dynamic problems of course stability of a wide-width sowing and row-crop-tractor unit. For constructing a computational scheme for the generated problem applied the central finite-difference method with a second-order accuracy. When developing a machine algorithm, the fractional grid steps are converted by formulas and a vector equation is obtained. The results of scientific and practical research and testing to determine and evaluate performance of machine-tractor units (MTU) consisting of inter row spacing sowing and cultivators with four-wheel tractors were obtained. Studies on appropriateness of increasing coverage area of cotton units based on field size have shown that the shift productivity of eight-row units at planting was lower than that of four-row units when the field area was less than 3 hectares. When the field area was 3 hectares or more, the MTU’s productivity increased by 32–34%. A similar trend has been observed in the inter-row processing units. Field experiments have shown that it is advisable to maintain the existing four-row machine system on the basis of existing energy vehicles for 27-30% of cotton fields. Cauchy problem for finite-difference equations of dynamic problems of course stability of a wide-cut sowing and tilled-tractor unit was formed, in the form of algebraic equations. As a result, it was possible to build 6-, 8- and 10-row cultivator units based on four-wheel tractors.

Abstract
In Uzbekistan, soybean is planted as a main crop in early Spring and as a follow-up crop after wheat in Summer. In the conditions of Uzbekistan, the height of soybean grown as a main and repeated crop is 63-99 cm on average, depending on the species and cultivation techniques, the diameter of the stems in the lower part is 4.1-7.1 mm on average, and it is higher in “Oyjamol” and “Amigo” sorts planted in the early period, after wheat and it was lower in the Selekta-201 sort planted as a repeated crop. It was found that the pod placement height was higher than 15 cm in the “Oyjamol” and “Amigo” sorts, while it was 6 cm in the Selekta-201 species , and this indicated the need to set the combine harvester height lower. It was found that the average number of pods in one bush of soybean is 21.0 - 29.8 pieces, the number of grains in a pod is 2-3 pieces, and the ratio of grain to stem is in the range of 1:1 - 1:1.8. This showed that the “Oyjamol” and “Amigo” species planted in the early periods have more grain and stem content than the Selekta-201 sort planted as a repeated crop.
Development of a roadmap as an important step towards the sustainable growth of the cocoa sector in Nigeria
Authors: Gavrilova Nina G 
Published: December 2022

Abstract
In Nigeria, the decline in the efficiency of the cocoa industry in particular and of agricultural production in general began after the country gained independence. At that time, oil was discovered, and that stole the attention of the government in terms of financing. Over time, the country’s budget has become highly dependent on fluctuations in prices for petroleum products, and there emerged a critical need to diversify state revenues. Nigeria’s successive governments over the past 60 years have made repeated attempts to revive agriculture as an alternative to the oil sector, but all of them have proven unsuccessful. The author believes that the recovery of the cocoa sector can become the most important vector for strengthening the country’s food security. Increased foreign exchange earnings from the export of cocoa products will enable Nigeria to purchase more food to meet the needs of the population. The author considers the lack of qualified management and competent agricultural policy in the country as the reason for the degradation of the cocoa industry and puts forward a roadmap for the development of the sector in Nigeria, which takes into account its current problems and may return the industry to the path of sustainable growth.

Abstract
Nowadays one can observe the penetration of digitalization into almost all spheres of life: political, social, economic, educational. Agriculture is not an exception. Russian government considers digital transformation in general and agriculture in particular to be one of the indispensable national goals. The ultimate goal of introducing digital changes is guaranteeing the RF entry into the top five largest economies in the world. Agriculture in RF has various branches where animal husbandry plays and important role in ensuring food security. Consequently, the issue of introducing digitalization into livestock farming as a less advanced industry is rather relevant. Digital data is becoming a key factor in the livestock industry. This data can be obtained from various devices, in particular from biometric sensors, big data and blockchain technology. Precision Livestock farming (PLF) technologies enable non-invasive sampling, helping farmers and researchers to obtain realistic indicators to solve welfare problems. The received and processed data allow obtaining information having new quality characteristics, searching for and finding patterns and models for agricultural successful modernization, minimizing risks of losses, forecasting using modern methods of big data processing, optimizing production costs. PLF technologies can also contribute to a reduction in resource use. They will definitely facilitate individualistic approach and a more proactive to animal health. Such an approach will ultimately reduce the need for medicines, especially the use of antibiotics. The use of innovative solutions was noted, in particular, the use of automated technologies, robotic systems, computerized programs, applications that contribute to the growth of productivity and the production of livestock products.

Published: December 2022

Abstract
The article considers the issue of developing a meat and vegetable product from local raw materials. The meat part is sub-products (collagen-rich pig ears and liver with high nutritional qualities) – raw materials, usually with low cost, but with proper processing with high taste, technological and nutritional properties. Local plant raw materials are represented by a not yet widespread crop chickpeas, which perfectly forms a crop in arid conditions of the Volgograd region of the Russian Federation, rich in vegetable protein, other macro- and micronutrients, and in addition, because it is a legume, enriches the light brown soils of the region with nitrogen due to symbiotic microorganisms. The developed product has high taste properties, contains an optimal set of macro- and micronutrients and can be called functional because 1 serving of the product contains more than 15% of average daily needs.

Published: December 2022

Abstract
Experimentally confirmed the need for fractionation of safflower seeds into large (width more than 3 mm) and small (width less than 3 mm) fractions in order to collapse the former on a centrifugal roller with a directional i.e. oriented impact and crushing the latter on disc huskers. Rational technological modes of collapse of a large fraction of safflower seeds have been identified: the angular velocity of the rotor is 198.9-251.3 rad/s, air consumption is 0.45-0.57 kg/s, seed moisture is 6.5-7.5% and seed width is more than 3 mm.
Development of Picea jezoensis (Siebold & Zucc.) Carriere trees at virginal ontogenetic stage in the Korean pine-broadleaved forest of the Southern Sikhote-Alin

Published: December 2022

Abstract
We described growth of Picea jezoensis (Siebold & Zucc.) Carriere trees at the virginal ontogenetic stage as one of the dominant species of the Korean pine-broadleaved forests in the south of the Russian Far East, Sikhote-Alin Mountains. Using dendroecological approach, we reconstructed stand disturbance history and studied impact of the disturbances on development of the P. jezoensis virginal plants. We found that severe stand disturbances lead to synchronous transition to the next subgroup of virginal stage and thus lead to appearing of generations of plants that may differ in age but are on the same ontogenetic stage of their development. We determined duration of plants development in the subgroups of the virginal stage and its total duration. We conclude that despite alternating periods when radial increment increases and, conversely, decreases, in general, the growth of virginal plants is relatively uniform and slow. Therefore, if growth conditions become less favorable because of climate change, this will cause the plants to be unable to access canopy and reach a generative stage.

Published: December 2022

Abstract
The article deals with the issues of large-scale mapping methodology for various landforms of the modern Amudarya delta. In the first, a relief plastic map and maps of the Amu Darya were compiled. In addition, the internal structure of small deltas, uplands and sandy areas is described. When studying the structure of the Earth’s surface, question arises on how it is depicted on maps in space and time. The depiction of the space of the Earth’s surface requires a knowledge of its shape and metrics, i.e. the length, how one system is located with respect to another, and also how their components are located with respect to all the others. On this basis, we applied new method (plastics of a relief) of mapping the forms of the Earth’s surface when using space photographs.
