Winter wheat seeded on soybean and lentil stubbles had high, stable yields compared to field peas, faba bean, canola, flax, and oats. Seeding into oat stubble resulted in lower and more variable yields. Crop diversity on the Prairies continues to expand, providing winter wheat growers with...
Winter wheat following late- or early-maturing canola hybrids had similar grain yields, but straight-cutting canola reduced the subsequent winter wheat yield. Applying pre-harvest herbicides while swathing with an on-board sprayer was effective in controlling weeds and maintaining winter wheat yields. Pre-harvest + pre-plant herbicides eliminated...
In susceptible varieties, a single foliar fungicide application at flag leaf reduced stripe rust severity and protected yield potential. A single fall foliar application was not effective. A moderately resistant variety did not require a spring foliar application. Stripe rust of winter wheat, caused by Puccinia...
In winter wheat cropping systems, pre-plant weed management combined with two in-crop fungicide applications optimized grain yield. An in-crop herbicide application proved to be unnecessary, however multiple applications of fungicides were needed to optimize grain yield and grain protein concentration. Winter wheat can offer substantial economic...
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...
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...
Cumulative NH3 loss (% applied N) from broadcast urea was highest with late-fall application at 16.4%, followed by 11.4% with winter applications and 2% with spring applications. Addition of NBPT urease inhibitor reduced losses by 65.6%. Broadcast urea is a practice that some winter wheat growers...
On the semi-arid plains, this 6-year crop rotation study found that increasing cropping intensity with spring wheat, pea or lentil could match annualized total grain yields of winter wheat-chemfallow, as long as winter wheat followed a cover crop or fallow. Winter wheat-fallow rotations are practiced to...
Researchers explored FHB management strategies focusing on a systems approach of Genotype (G) x Environment (E) x Management (M) interactions. They reviewed current literature, and included a recent western Canadian FHB research project as a case study of this approach. The results showed that a...
Three enhanced efficiency nitrogen (N) fertilizers applied at seeding or in split applications between fall and spring did not reduce nitrous oxide emissions compared to conventional urea or UAN fertilizer when applied at 80% of recommended rate. A split application of 30% N at seeding...
