Efficiency of mineral fertilizers, trace elements and humic-based preparations application in the cultivation of winter wheat

Abstract

The introduction of a carbamide­ammonia mixture to­ gether with trace elements of copper and manganese and humic­based preparations Gumidar and Gumistim contribut­ ed to an increase in winter wheat grain yield by 0,5–5,9 c/ha, gluten content – 4,7–4,6 %, profitability level – 10,7–3,1 per­ centage points, bioenergetic coefficient – 1,4–1,9 units com­ pared with the control variant. The best options are where the carbamide­ammonia mixture was introduced together with copper and manganese, and humic­based preparations Gu­ midar and Gumistim against the background of N25P50K110, since the yield of winter wheat was in the range of 71,3– 71,9 c/ha. At the same time, the level of profitability and the bioenergy coefficient amounted to 64,6–62,3 % and 4,8 units, respectively.
