The article presents the studies conducted in the Tersko-Sulak sub-province of the Republic of Dagestan aimed at phytomelioration of medium-salted meadow-chestnut soils by cultivating varieties of grain sorghum. The following was revealed. The duration of the growing season of early ripe varieties ranged from 99-101 days, and mid-ripening - 113-115 days. When treated with growth regulators, a decrease in the growing season was noted. Higher values of photosynthetic potential were noted in Khazine 28 and Zernogradskoe 53 varieties. The applied growth regulators contributed to the increase of these indicators. Among the studied early ripe varieties, Khazin 28 provided the highest yield, and among the mid-ripening varieties - Zernogradskoe 53. The same varieties provided the maximum removal of harmful salts from the soil. Against the background of processing by growth regulators, an increase in the yield of grades of grain sorghum was recorded, which, in turn, led to an increase in salt removal.
