This article contains information on the effect of soil salinization on quantitative indicators of photosynthetic pigments of plants. The hairy vicia plant (Vicia villosa Roth) was chosen as the object of research. This plant has been studied in conditions of weak, medium and highly saline soils. The results showed that an increase in soil salinity led to a decrease in the amount of chlorophyll (Chl) «a», an increase in the content of chlorophyll (Chl) «b» and carotenoids (Car). It was found that during the growing season, the leaves of plants in the blooming phase contain a large amount of pigments. In slightly saline soil, the content of chlorophyll «a» in plant leaves was 5.42 mg/g, and in highly saline soil -4.88 mg/g. The content of (Chl) «b» increased from 1.89 mg/g to 3.19 mg/g, respectively. This is exactly the result observed for carotenoids (Car), recording an increase of 1.69 mg/g from 1.45 mg/g. When determining the amount of photosynthetic pigments in plants in saline soil conditions, it was considered advisable to use leaves during the blooming period.
