A brief analysis of the results of the main published works on the problem of "digital agriculture" in the Russian Federation is presented and it is noted that in general, the lack of basic elements of digital agriculture and the corresponding infrastructure hinders the introduction and development of these technologies, equipment, materials and does not contribute to the development of digital agriculture in Russia; a comparative analysis of well-known digital models of growth and productivity is presented (E.A. Mitscherlikh, V.G. Griguletsky). Based on a new digital model of the growth and productivity of agricultural crops, calculations were carried out for different plants and soil and climatic conditions, showing good agreement between the experimental and calculated (predicted) yield values. For the first time, on the basis of numerical calculations, the values of the coefficients of action of various factors were determined and the nature of changes in plant growth curves was substantiated: the initial stage of normal plant development occurs according to an exponential law, then a phase of direct proportional dependence of plant growth (weight) on the amount of active nutrients begins, a further increase in the amount of nutrients substances reduces the growth rate and slows it down.
