This paper presents an original information system supporting the management of an agricultural holding codenamed AGMS (Agro-Management System). This system was created in C# language, using ASP. NET MVC programming technology. The application database layer was supported by SQL Server and Entity Framework technology. The creation of the program's views enabled such languages as HTML 5, CSS3 along with Bootstrap library and Javascript with dedicated Knockout.js library. The development of the system was preceded by an analysis of requirements, in accordance with software engineering procedures. The documentation created at this stage in the form of UML diagrams was prepared in Microsoft Visio. The AGMS program presented in this article is a developmental version, so all its functionalities are not yet fully implemented. The user can use the current version of the software to map fields, manage events related to individual fields and, among other things, obtain information on pests and weeds. The article also describes the concept of the final version of the program, which should include modules implementing simple methods of artificial intelligence in the field of image recognition and decision support.
