Liquid UAN with an urease inhibitor in a split application optimized N use efficiency, grain protein, yield and yield stability. EEFs did not affect greenhouse gas emissions. With the development of enhanced efficiency fertilizers (EEF), winter wheat growers have the opportunity to improve nitrogen use efficiency...
Average faba bean nitrogen (N) uptake was 205 pounds per acre (230 kg N/ha) and phosphorus (P) uptake was 23 lbs/ac (26 kg P/ha). Overall, faba bean fixed 88% of its nitrogen from the atmosphere. Faba bean is a high-protein pulse crop that has the potential...
On dryland sites that have low to moderate productivity, winter wheat growers should band all N at planting to ensure maximum grain yield and protein content. For irrigated winter wheat production or in dryland areas with high yield potential, a split application of fall banded...
Under relatively dry conditions of this study, grain yield was not influenced by rate, source or timing. Split application of N resulted in higher grain protein. The application of a PGR increased grain yield but resulted in lower grain protein. When high N rates were...
Management strategies such as split N application and the use of a plant growth regulator can help reduce lodging while maximizing yield and protein in spring wheat production. Farmers are achieving higher wheat yields today than in the past; however, there remains a gap between yields...
Moving to a high seeding rate increased DM and TDN yields and decreased CP and P concentrations in forage corn. Using a high nitrogen fertilizer rate increased yields of DM, TDN and CP, increased soluble protein concentration, and reduced P concentration. However, when net returns...
Low plant density, split nitrogen, and PGR application all showed potential to reduce lodging risk without reducing grain yield or protein concentration. Today’s high yielding spring wheat varieties bring with them the potential for lodging under high nitrogen inputs. The objectives of this study were to...
A nitrogen fertilization rate of 44.5 lbs N/ac maximized canarygrass seed yield. Foliar fungicide application increased seed yield by 8.5%, and is important in areas where septoria leaf mottle is prevalent. The fungicide application did not improve the responsiveness of canarygrass to N fertilizer, so...
Starter nitrogen (N) up to 75 lbs. N/ac broadcast and incorporated before planting a Maturity Group 00 soybean cultivar found no differences in biomass, grain protein, or oil content. There was no yield response for treatments receiving starter N fertilizer relative to the unfertilized control...
[Editorial Note: This 26-site research study was conducted across the Prairies 20 years ago, but results and lessons learned are still applicable today.] In-crop application of 14 lbs. N/ac of broadcast ammonium nitrate or foliar-applied UAN were generally equally effective at increasing grain protein content in...
