The article presents data from a field and laboratory experiment conducted on takyrodnyh soils and emergency conditions in southern Uzbekistan. The height of the breeder plant in the control was 84.0 cm, the number of boxes was 8.2 pieces, and in the experimental versions, the height of the plant was 82.0-90.1 cm, the number of boxes was 7.9-8.9 pieces.
