The article reveals the influence of different doses of potash fertilizers in the prevention of the disease “black smut” in winter wheat, on the development of plants and wheat yield. It enhances the outflow of sugars from the leaves to other parts of the plant, increasing the activity of enzymes involved in the metabolism of carbohydrates, including amylase. Due to potash fertilizers, it is possible to obtain up to 6.0 c / ha of additional yield. The potassium efficiency of post-cotton wheat is increased to some extent, but the economic efficiency is reduced. We have conducted scientific research on the use of various standards of potash fertilizers for the prevention of black smut disease in the “Chillaki” wheat variety on the light gray soils of the Andijan region.
