In 2015-2017, in the context of the Tersk-Sulak subprovince of the Republic of Dagestan on irrigated saline lands, studies aimed at the study of adaptive potential of amaranth varieties (Kizlyar (standard), Valentine, Iriston) with the use of growth regulators were conducted. As a result, it is revealed that the applied growth regulators contribute to the reduction of the vegetation period of the studied varieties. In addition, the regulators have increased the area of the leaf surface and net productivity of crops. In the analysis of the harvest data found that the higher the data provided a variety of Iriston and lows of Valentine's day. Applied growth regulators increased the yield on average by 13.4-15.3% for varieties.
