Abstract
Relevance. In conditions of low-fertile sod-podzolic sandy soils, they worked out the opportunity to obtain stably high yields of winter wheat grains of Moskovskaya 39 variety, many works are devoted to the effect of nitrogen fertilizer on yields in the scientific literature, and in the situation of radioactive pollution, the study of the role of potassium fertilizer and biological preparation in increasing the yield of winter wheat grains becomes especially important.
Results. It was found that the use of potash fertilizer on the background of high doses of nitrogen-phosphorus fertilizer was justified, a strong connection was found (r = 0.71), between increasing doses of potash fertilizer and yield, the use of the biological preparation Humistim strengthened this connection (r = 0.90). It was revealed that the highest grain yield of 5.54 tons/ha of winter wheat on sod-podzolic sandy soils with low content of exchange potassium was obtained using the organo-mineral fertilizer system, the payback of 1 kg d.v. of the introduced full mineral fertilizer in the norm N120P90K150 was 7.78 kg of the winter wheat grain yield increase.
