In western Canada, Sclerotinia stem rot continues to be a serious disease of canola. Researchers at the University of Manitoba led a two-year study to assess the risk of sclerotinia stem rot disease on canola based on standard weather conditions and the canopy microclimate.
Early season phosphorus nutrition is critical for optimum crop yield. Researchers at Agriculture and Agri-Food Canada conducted a three-year multi-site field study to assess the impact of phosphorus fertilizer applied with and without phosphate-solubilizing inoculant Penicillium bilaii on the growth, phosphorus uptake, yield and quality of canola.
Researchers in Saskatchewan led a three-year study to assess the potential effects of increasing the frequency of canola in rotation on weed abundance, species distribution, community diversity and function in canola-inclusive rotations across western Canada.
Large harvest bags (silo bags) are becoming popular for on-farm temporary storage of grains and oilseeds in western Canada. Researchers at the University of Manitoba conducted a three-year study to quantify the changes in seed quality of canola during bag storage under Canadian Prairie conditions.
Management of stubble height is an inexpensive crop management technique that can have a potentially beneficial impact on seedling germination and emergence.
Growing canola in tighter rotations increases risks and can dramatically decrease yields. Researchers conducted two 6-year studies to determine the agronomic and economic implications of growing canola in "tight" rotations.
Wild oat continues to be the most economically important weed problem in Canada. Researchers conducted a study to determine if diverse rotation treatments combined with other cultural practices would reduce wild oat populations, and if diverse crop rotations would influence wild oat seed bank, soil microbes, and crop quality.
A four-year study initiated in 2010 was conducted in western Canada to investigate the differences in biology of two flea beetle species, Phyllotreta striolata (striped) and P. cruciferae (crucifer), in order to better target management methods.
Canola cropping systems harbour a diverse fauna of arthropods (insects, spiders, mites, and their relatives) at several trophic levels, and understanding their biodiversity can improve the ability to enhance the long-term sustainability of canola production.
Canola seed is a substantial input cost and poor canola stand establishment is a continuing concern for canola growers. On average, only 50% of planted seeds emerge; even when germination is above 90%.
A three-year study was initiated in 2010 by researchers with Agriculture and Agri-Food Canada to focus on developing novel assessment technologies and crop management tools for control of insects, weeds and diseases in canola.
Canola varieties with high oil content have predominantly replaced low oil content canola grown in western Canada. Researchers in Manitoba conducted a three year study to develop more reliable safe storage guidelines for high oil content canola.
