Thicker stands improve weed management

Key practice: Higher seeding rates mean a more competitive crop, which can translate into higher yields and lower in-crop weed management costs. Key research: Harker, K.N., Agriculture and Agri-Food Canada (AAFC), et al. “High-Yield No-Till Canola Production on the Canadian Prairies.” Canadian Journal of Plant Science. (2012). Harker, K.N., AAFC, et al. “Seeding Rate, Herbicide...

Reduce losses while combining

Key practice: Ground speed and mechanical adjustments to the combine can reduce harvest losses and increase yields. For growers who want to try straight combining, start with one field with uniform maturity and high yield potential. Key research: Gulden, R.H., University of Manitoba, et al. “Evaluation of Harvest Losses and Their Causes in Canola Across...

Seed at 1/2″ to 1″ deep

Key practice: Optimum seeding depth is ½” to 1″ below the press wheel furrow. This reduces days to emergence and improves plant population and uniformity, which produce season-long benefits. Key research: Harker, K. Neil, Agriculture and Agri-Food Canada (AAFC). “Seeding Depth and Seeding Speed Effects on No-Till Canola Emergence, Maturity, Yield and Seed Quality.” Canola...

Micronutrients: Take care of macros first

Key practice: Economic response to micronutrient applications is rare for canola in Western Canada. However, if growers apply recommended rates of nitrogen, phosphorus and sulphur and yields are not increasing, growers may want to check the micronutrient situation. Key research: Karamanos, R.E., Westco Fertilizers, et al. “Canola response to boron in Canadian prairie soils,” 2003,...

Store it, but don’t forget it

After escaping all the yield loss traps in the field, there is one more obstacle to overcome before delivering canola to the elevator: storage. Grain mismanaged in a bin can result in disappointing losses. Paying attention to the moisture and temperature of the grain as well as outdoors is critical to management. Canola storage was...
