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...
Using a cultivar with greater disease resistance and applying a fungicide reduced leaf spot diseases in winter wheat. Fungicide application resulted in a 3.3 to 13.2% (2 to 8 bu/ac) yield increase over the untreated check. Leaf spot diseases are commonly seen on winter wheat in...
Barley silage and pea stubbles were identified as high-yielding alternatives with higher protein and greater stability compared to canola stubble in the Black soil zone. Barley grain stubble was identified as intermediate stubble option while oat stubble was a poor option. Research was conducted to investigate...
Split applications of N usually provided the maximum yield and protein, particularly with Agrotain or SuperU. This study consisted of two experiments each conducted at five sites across western Canada at Brandon, Manitoba, Hallonquist (south of Swift Current), Saskatchewan, and Lethbridge and Lacombe, Alberta to assess...
Two research studies investigated best management practices for winter wheat stand establishment at 26 sites over three years across western Canada. A strong, integrated agronomic system with high seed rate near 40 plants per square foot, a dual fungicide/insecticide seed treatment, and vigorous seed provided...
Field trials found pyroxasulfone (Focus), pyroxasulfone + flumioxazin (Fierce), and pyroxsulam (Simplicity) provided effective control of Japanese and downy brome in winter wheat. Trials were established at Lethbridge and Kipp, Alberta, and Scott, Saskatchewan, over three growing seasons to compare herbicides for control of downy and...
