Abstract

Agroeconomical efficiency of mineral and organomineral systems of winter wheat fertilization with the use of cattle manure and straw is analyzed in the field technological experience. The most optimal for winter wheat on medium-cultivated sod-podzolic sandy loam soil was a fertilizer system, including the application of N70+40+40P65K115 on straw with a compensating dose of nitrogen, which provided a grain yield of 64.1 c/ha with a crude protein content of 14,24 %, gluten – 28,94 %, coefficients of compensation for the removal of nutrients by harvest: N – 1,4, P2O5 – 1,2, K2O – 2,5, conditional net income provided grain is sold as food – 455 USD/ha, the profitability of the use of fertilizers – 195 %, when used for fodder – 71 USD/ha and 31 %, respectively.
