EFFECT OF WATER-SAVING IRRIGATION TECHNOLOGY BASED ON USING HYDROGEL POLYMER COMPOUND ON GERMINATION AND PLANT THICKNESS OF WINTER WHEAT

The use of a highly swelling hydrogel polymer compound, synthesized from local raw materials, as a water-saving irrigation technology at different rates during the cultivation of the winter wheat variety “Starshina” on gray-brown, light sandy soils with a non-saline profile in the newly developed desert zone of the Bukhara region, affects the germination and seedling density of winter wheat. The results of this effect are presented. In the experimental works, the hydrogel was applied at the following rates: in the 1st option (control), no hydrogel was used; in the 2nd option, 50 kg ha-1; in the 3rd option, 75 kg ha-1; in the 4th option, 100 kg ha-1; and in the 5th option, 125 kg ha-
