[Evaluation of seasonal dynamics of crop yield in agrocenoses on the basis of satellite data and mathematical model].
An integrated approach based on satellite remote sensing data and the results of mathematical model analysis was tested for applicability in evaluating the crop yield and total of phytomass of agrocenosis and identifying its type. The dynamics of the normalized difference vegetation index (NDVI) and the total aboveground phytomass of agrocenosis proved to be qualitatively similar. An analysis performed using the mathematical model and taking into account air temperature showed the possibility of making and refining prognosis of crop yield. In this course, the vegetative and generative parts of the agrocenosis were distinguished, and it was found that the model data matched the ground survey data under optimal environmental conditions.
