Crop rotations significantly influence canola yields, showing a 7.5% yield reduction in continuous canola rotations compared to canola grown after a cereal crop. Conversely, canola yields increased by 3.8% when grown after lentils and 4.7% after peas compared to canola grown after a cereal crop. In...

Fall application of Zero Grind limestone performed similar to spring applied hydrated lime. Generally, both products applied at 10 t/ha increased soil pH, reduced disease severity, increased yield and reduced spore density of P. brassicae in the soil. Clubroot, caused by Plasmodiophora brassicae Wor., is well...

For both early- and late-maturing hybrids, straight-cutting canola at 10% seed moisture produced high, stable yields. While seeding at 18 seeds/ft2 produced the highest yield, it also had the lowest net returns due to high seed costs. Seeding at 12 seeds/ft2 provided a balance between...

When strip tillage was combined with a disc-hoe opener, a high and stable canola yield was achieved. No-till improved water conservation and helped to mitigate yield losses in rainfed conditions of southern Alberta. Strip tillage has been adopted for planting crops in wider row spacing because...

Safflower and sunflower demonstrated potential as trap crops to reduce Lygus damage to faba beans. The Lygus pest complex in the Canadian Prairies is dominated by L. lineolaris, L. keltoni, L. elisus, and to a lesser extent, L. borealis. While Lygus have a broad host range,...

Swede midge was not detected in canola grown in the Northern Great Plains between 2006 and 2021. Monitoring continues in North Dakota and western Canada to ensure early detection of swede midge if it continues to move northwestwards. The swede midge, Contarinia nasturtii (Kieffer) is an...

In addition to genetic, physiological, and environmental factors, farming practices such as harvest timing, and tillage regimes can influence secondary dormancy of volunteer canola seed. Given the documented high heritability of secondary dormancy, it is feasible to reduce secondary dormancy in canola cultivars through plant...
