Over the period 1996 to 2020, the farm level economic benefits from genetically modified crops increased global farm income by $261.3 billion US dollars. In Canada, the average farm income increase from growing herbicide tolerant canola was $23.49/ac ($58.01/ha). Genetically modified (GM) soybean, corn, cotton and...

A research review of 89 canola studies found that the potential on-farm monetary loss from uncontrolled weeds in canola was about $2.21 billion on the Prairies, $0.16 billion in North Dakota, and $2.37 billion in both countries combined. Potential yield and financial losses from weed competition...

In small plots and greenhouse conditions, blackleg severities on 2 canola hybrids were generally higher when Leptosphaeria maculans was co-inoculated with Verticillium longisporum than when L. maculans was applied alone. Blackleg disease, caused by L. maculans, has been an important disease in western Canada for many...

A research study reviewed factors affecting nitrogen, sulphur and water use efficiencies, and found that 4R stewardship of nutrients and some agronomic practices provided the greatest improvements. Economic and environmental sustainability of canola production is gaining more scrutiny in this era of emissions reductions and climate...

Research shows that the highest plant densities and yields were produced at a narrow row spacing of 9 inches compared to those of 12, 18 and 24 inch spacings in a no-till production system. Increasing seeding rates of 2.8, 5.7 and 8.5 pounds per acre...

Mechanical wounds on canola cotyledons, simulating flea beetle feeding, allowed infection of the blackleg pathogen while no infection occurred on un-injured cotyledons. Wounds that were 8 hours or older before inoculation had lower levels of infection. Temperature, leaf wetness and relative humidity also played a...

The application of hydrated lime to bring an acidic soil up to pH 7.2, and/or weed control of cruciferous weeds did not affect clubroot severity on a clubroot resistant variety. The yield of a susceptible canola variety almost doubled with the application of hydrated lime,...

Under  irrigated and high-precipitation conditions, canola yield from 12 inch narrow-row precision planted canola was 10% higher than canola seeded with a 12 inch row air drill. However, under more water-limited conditions, yield from air drill seeded canola was equal or higher than the precision...
