Simulated hail damage led to reductions in height, biomass, NDVI, grain yield, and kernel weight in wheat, field pea and dry bean. Average yield losses from heavy hail damage were up to 35% in wheat and dry bean, and 45% in field pea. Hail damage...
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...
Research found that foliar fungicide application at early anthesis for Fusarium Head Blight control also provided adequate control of leaf spotting diseases. While leaf spotting diseases were slightly higher at this timing, yields were similar. In years when environmental conditions are favourable, leaf spot disease can...
All cultivars in spring wheat classes CWRS, CWSWS, CPSR, CWSP and CNHR had similar yields between the 2C and 8C trigger planting temperatures. However, the ultra-early planting date had improved grain yield stability and improved growing system stability. Research from 2015 to 2018 by Collier et...
The most profitable practices were applications of propiconazole (Tilt 250E0), benzovindiflupyr and azoxystrobin (Trivapro A+B) at BBCH 39-45 (flag leaf) or prothioconazole and tebuconazole (Prosaro XTR) at BBCH 61-63 (early anthesis) -- when environmental conditions were conducive for disease development. The objective of this study was...
In this study, foliar phosphorus (P) application was unable to substitute for seed-placed P. Overall, foliar P had a marginal effect on grain yield, P uptake and seed nutritional value. Generally, little research has been conducted in western Canada to assess the potential of foliar-applied phosphorus...
Seed wheat as soon as feasible after soil temperatures reach 0C, and prior to soils reaching 7.5–10C, with an optimal seeding rate of 40 seeds/ft2, and at a shallow seeding depth. Ultra-early seeded wheat increased grain yield and stability compared to current seeding practices. Using...
Wider row spacing in wheat is possible – up to 16 inches – but producers need to monitor their plant density to ensure they are reaching an adequate stand establishment to achieve optimum yield, especially since all seeding equipment may not maintain separation of seed...
After seven years of pre-seed glyphosate application in a wheat-wheat or wheat-pea rotation, in min-till or no-till, there were few effects on the wheat rhizobacterial communities. Due to widespread adoption of no-till management and use of glyphosate-resistant transgenic crops, glyphosate is the most widely used herbicide...
[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...
