Digging into Research
Wheat midge parasitism was found to be as high as 71% in the Peace River region of Alberta. Parasitism was primarily by Macroglenes penetrans, the main parasitic wasp species that attacks wheat midge on the Canadian Prairies. A parasitic wasp species, Inostemma walkeri, was newly...
Wheat, canola and chickpea yield and the overall average water use efficiency increased linearly as stubble height increased to 18 inches (45 cm) compared to cultivated stubble. Water use was independent of stubble height. Previous research on the semiarid Prairies found that seeding into 12 inch...
FHB status updateFusarium head blight incidence increased steadily after 1995, peaking in the epidemic year of 2016, but with low levels since then. Severity has remained relatively low over time, and not always correlated to incidence levels. Fusarium head blight (FHB) emerged as a serious disease...
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...
A long term rotation study at Swift Current, Saskatchewan found that a diversified crop rotation with wheat-canola-wheat-pulse produced more grain and protein yield than traditional cereal or fallow systems. The rotation was more stable over the years, and had high nitrogen use efficiency (NUE). To meet...
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...
Fall applications of flumioxazin, pyroxasulfone, and combinations of flumioxazin and pyroxasulfone to manage weeds emerging the following spring is a safe and effective weed management program in ultra-early seeded wheat. Ultra-early planting of wheat with a soil temperature trigger of 0-2.5 C has been shown to...
A long-term study at Indian Head, Saskatchewan evaluated the effect of medic on grain yield, N and P of flax, wheat and oats with three different N treatments. Overall, medic had the greatest impact on crop productivity at the low N rate of 20 per...
The gap between actual wheat yield and potential wheat yield has remained relatively stable since 1960 in the top 10 wheat producing countries. Understanding yield gaps between actual and potential yield is a tool to help increase wheat production around the world. Estimates indicate that an...
