Abstract
In a field technological experiment on sod-podzolic sandy loamy soil, the agro-economic efficiency of various winter wheat fertilization systems was studied, depending on the method of basic tillage. The incorporation of straw without a compensating dose of nitrogen, both during traditional and surface tillage, did not adversely affect the uniformity of seedlings and the development of winter wheat plants on soddy-podzolic sandy loamy soil. On sod-podzolic soils in field experiments, on average for 3 years, due to the effective fertility of medium-cultivated sandy loam soil, 40,9 centners/ha of winter wheat grain was obtained, the most optimal on sod-podzolic sandy loam soil in the plowing block was a fertilizer system, including the application of N70+40+40P55K45 against the background of straw, which ensured the formation of a winter wheat grain yield of 68,6 centners/ha, with surface tillage of the soil, a fertilizer system that includes the application of N70+40+40P65K115 against the background of straw treated with the microbial preparation Zhytsen in a dose of 3 l/ha ensured the formation of a winter wheat grain yield of 733 centners/ha. Grain quality indicators are determined.
