canolacalculator.ca will help farmers find plant densities and seeding rates that minimize risk and maximize profit potential. The tool depends largely on farmer-funded research.
With a change in machinery, Red River Valley farmer Brad Erb had to give up his time-of-seeding nitrogen banding. So he opted for the next best thing to reduce losses for his soil type: Fall banding.
Grower-funded research at the University of Alberta has helped CPS bring new clubroot-resistant (CR) canola hybrids to market. These and other sources of CR canola has kept the crop economically viable in clubroot-infested areas.
One bertha armyworm per square metre can reduce canola yield by 0.058 bu./ac. So, 17 of them per square metre will drop yields by around 1 bu./ac. This information helps growers assess the threat and spray only when numbers are sufficient to provide a return on investment. How do we know these thresholds? Research.
