Optimization of soil water and N addition is essential to improving wheat drought resistance. Overall, the results showed that moderate drought priming along with nitrogen application can improve drought resistance, yield, and grain quality in spring wheat. One of the significant challenges for crop production is...
Intercropping chickpea and flax resulted in eight to 22 per cent of biologically fixed nitrogen being transferred from chickpea to flax during the growing season. This resulted in reduced soil nitrogen depletion compared to monocrop flax. The land equivalent ratio was at or above 1...
In a grain legume-wheat rotation, belowground residue consisting of roots, rhizodeposits, residual fertilizer and soil-N contributed 70 to 91% of wheat N uptake, with 66% of N uptake from the indigenous soil N pool. Wheat yield was statistically highest following lentil and pea, which were...
A two year study found that the alternate nitrogen (N) fertilizer sources ammonium sulfate nitrate and calcium ammonium nitrate did not perform any better than urea N fertilizer. Treatment with a urease, nitrification or dual inhibitor had few benefits. A two-year field study assessed the impact...
On Dark Brown soils, the use of a dual-inhibitor EEF resulted in increased grain yield and delivered improved net return benefit compared to urea. Other EEF sources tested yielded similarly in the Dark Brown soils. However, in the Black and Grey soils, the EEFs tested...
Nitrification-inhibitor products – either alone or in combination with an urease inhibitor – reduced N2O emissions by 38% to 43% compared to untreated urea in spring wheat in southern Manitoba. However, there were few yield or grain protein benefits to using the EEFs products. Environment and...
Canola yield increased by up to 40% with increasing N rate up to 134 lbs/ac (150 kg/ha) pre-plant (i.e. close to seeding) application via broadcast or banding. There was no significant difference in yield between pre-plant only N application and a split pre-plant plus top-dress...
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...
