Relevance. The concept of precision agriculture call for the use of physical and mathematical, technical and software tools for obtaining and processing information about agroecosystems, as well as for the implementation of agricultural practices directly in the field. To date, there are quite a few software products that can control the production of crops, in particular, the management of differentiated fertilization and compliance with elements of cultivation technology. The purpose of our research conducted over two years was to develop and test in real field conditions algorithms for the functioning of the module of the information and analytical system of crop management for specialized crop rotations involving flax.Methods. The objects of research were the elements of the information and analytical management system for resource-saving production of crop production "Vash urozhaj" (IASUR) and flax-long-lived variety Tonus (selection of the FSBI FNC LC). The experiment used an electronic field map in kml file format containing the coordinates of points, quantitative characteristics of indicators of the content of nutrients and chemical elements in elementary areas within the surveyed spatial object, a technological map of the cultivation of flax, developed specifically for this variety, task maps for the application of solid and liquid fertilizers in .csv file format.Results. Developed and formed in the information and analytical system "Vash urozhaj" electronic technological map of the cultivation of flax-long-legged variety Tonus, containing a list of technological operations, timing and quality characteristics of their implementation, including a possible set of machinery and equipment. The possibility has been tested and the effectiveness of the module for obtaining climatically secured flax yield has been determined — the planned estimated yield for this flax variety at the pilot site is 4.3 c/ha. When cultivated according to the technology adopted in the Federal Scientific Center of Bast Cultures, introduced into the agroplatform, a yield of 4.0 c/ha was obtained. The yield deviation by 6.98% relative to the calculated one is due to the weather features of the growing season of 2021.

The object of the research is the module of the Informational and Analytical Crop Management System with differentiated fertilization. The aim of the research was to study the features of the implementation of the functionality of the Information and Analytical Crop Management System (IACMS) with differentiated fertilization. The key element of using the capabilities of the Information and Analytical Crop Management System for is the digitization of fields and the creation of their electronic maps. Differentiated fertilization was carried out in accordance with electronic maps compiled during the agrochemical survey. Digital maps of the fields were entered into the on-board computer of the tractor, equipped with additional devices for the implementation of the differential fertilization mechanism. In accordance with the main goal of the research, the tasks of checking the automated calculation of fertilizer application rates were solved for fiber-flax on the field belonged to Federal State Budget Research Institution «Federal Research Center for Bast Fiber Crops», preparation of a task-map for differential fertilization in CSV-format files and containing the number of the elementary plot and the value of the applied fertilizers, compatibility of the task-map of differentiated fertilization with the equipment of LLC “Center of Precision Agriculture «Aerosoyuz» (LLC «CPA «Aerosoyuz»»), aggregation of equipment with Russian technologies, the interaction of the working bodies of equipment for applying fertilizers with (IACMS), the possibility of controlled passage of the equipment, differentiated fertilization in compliance with the norms of task-maps.

Relevance. The introduction of digital technologies into the flax industry is an integral part of increasing production efficiency. Competently adapted new digital solutions are prerequisites for expanding opportunities and strengthening of the competitive position of both individual economic entities and the industry as a whole. One of the main reasons of limitation of the introduction of new, including digital, technologies in flax cultivation is a high proportion of physically worn out, with depreciation up to 100%, and obsolete equipment, which often leads to critical deviations in technological operations, from pre-sowing tillage to post-harvest works. This is reflected in the effectiveness not only of the individual operations carried out (poor-quality performance, lagging behind the deadlines, etc.), but also on the efficiency of flax cultivation and, ultimately, on the profitability of the flax-growing business itself. Considering that many farms still use equipment manufactured in the 1970s initially there is a question of widespread introduction of complex mechanized and automated technologies, and then the transition to the use of digital technologies and automated control systems. In this regard, the task of scientists is to create conditions for the introduction of innovative technologies and the development of agricultural services for the digital transformation of agricultural production.Methods. The work used a wide range of analytical methods used to study economic phenomena in the agro-industrial complex, in particular, in flax growing.Results. The main advantages of digital transformation of agricultural production processes in flax growing are considered, scientifically grounded developments of the Federal Scientific Center for Bast Crops and JSC Scientific Research Institute of Information Technologies in the field of information and analytical system of crop production management are proposed, a model for managing business processes based on digital transformation and state support for the introduction of digital technologies at all stages of the production process is proposed.
