The article is devoted to the use of models of formation of a crop in the management of agricultural production. The authors emphasize that the use of modeling approach is particularly effective if it is combined with the use in precision agriculture. The article provides a brief overview of the models of the production process, developed over the past 40 years. The classification models of formation of a crop reflecting the current state of the question. According to the destination model can be divided into two basic classes: dedicated to theoretical studies and to solve practical problems. Models for research purposes are used for accumulation and integration of knowledge, implementation research and testing hypotheses, student learning, interdisciplinary information exchange. Models for practical purposes, allow solving a wide range of technological, economic and environmental objectives. By their nature, and the formal description of the model can be divided into heuristic (static) and causal (dynamic). The basis of the heuristic models laid different approaches and concepts: black box, feedback and transfer functions, finding and description of statistical regularities in the observed or experimental data and other methods to link the response or reaction of the simulated object to an external stimulus. In terms of process visualization model can be divided into numerical (2D), structural (3D) structural and functional models. The authors conclude that the methodology of simulation objects plant deserves wider application of research and development in environmental and agro-biological systems. Using models of plant growth and development in the management of agricultural production in the area of economy and technology is one of the most effective means of improving productivity and sustainable use of natural resources.
