Estimation of predictability of agrophytocenoses productivity was made by comparing the results of
investigation of a mathematical model, field experiments and satellite measurements. The mathematical model of
the seasonal dynamics of agrophytocenoses productivity was built with account of air temperature. For model
investigation the coefficients were used that were calculated on the basis of the results of field experiments
conducted in the Republic of Khakassia. The objects of the research were agricultural crops (wheat, oats). The
results of satellite measurements (NDVI dynamics), and theoretical and experimental results of the seasonal
dynamics of plant total biomass proved to be quantitatively consistent
