The accuracy analysis of the regression model developed earlier was tested using independent 3 years data sets. Grain yields were forecasted with simple linear model of type: Yd= a+b LAI in flowering. Grain yield and LAI from many points of experimental fields with highly variable soil suitability complexes were considered. The model forecasted the grain yield quite well for the considered years and soils without water and nutrition limitation
