The article describes the effect of soil salinization on the level of correlations between quantitative indicators of photosynthetic pigments in vetch varieties. The objects of the study were the varieties of wiki Mirzachul-1 ( Vicia villosa Roth) and Mirzachul-3 ( Vicia angustifolia . L.). It was found that in highly saline soils, compared with weak ones, the amount of chlorophyll Chl «a» in the Mirzachul-1 variety decreased by 308 mg/g, the amount of chlorophyll Chl «b» and carotenoids (Car) increased by 0.11214 and 0.1300 mg/g.There was a strong positive correlation between Chl «a» and Chl «b» in all variants of the study. The similarity of correlation matrices is studied. At the same time, the similarity of correlation matrices between weakly and strongly saline soils was noted in the Mirzachul-1 variety by more than 90%, in the Mirzachul-3 variety by 69.1%. This indicates that the Mirzachul-1 varieties are stable in terms of the level of correlations according to the studied characteristics, which indicates a tendency to soil salinization.
