Core Ideas Spring wheat did not respond to additional nutrients beside recommended nitrogen. Seed inoculation with Trichoderma spp. did not impact yield or protein. Additional P, Cu, Zn, and S did not change grain protein.Nutrient management is critical for improving spring wheat ( Triticum aestivum L.) yield and protein content. During 2014 to 2016, field experiments were conducted to determine the potential of nutrient applications with recommended nitrogen (N) to improve wheat production near Glyndon, MN. Treatments were additions of phosphorus (P), sulfur (S), copper (Cu), and zinc (Zn), alone or in combination, and inoculation with growth promoting bacteria ( Trichoderma spp. ) in addition to recommended nitrogen (N) fertilizer on grain yield and protein content. Growing year had a significant effect ( P < 0.05) on yield and protein content. Applications of mono ammonium phosphate (11–52–0) at the rate of 40 lb P 2 O 5 /ac and combined applications of Cu, Zn, and S increased grain yield over the recommended treatment and check, in 2015 only. There was no significant impact on grain protein content by the applied treatments. In this study, supplemental additions of nutrients did not increase spring wheat yield and protein content.
