Aim for uniform stands

Key practice: Uniform stands, with the same number of plants per square foot across the field and with plants at the same growth stage, are proven to increase yields. Key research: Angadi, S.V., Agriculture and Agri-Food Canada (AAFC), et al. “Yield Adjustment by Canola Grown at Different Plant Populations under Semiarid Conditions.” Crop Science 43...

Potassium deficiency shows first in cereals

Potassium deficiency symptoms will show up in cereals well before it shows up in canola. As you can see in this photo, potassium deficiency in barley looks a lot like leaf diseases. Soil tests and tissue tests may help identify the problem.
Most canola crops grown in Western Canada are not short of potassium because most Prairie soils have sufficient potassium levels. Sandy soils with low clay content are most likely to be short of potassium, especially if those fields have been in forages where a large percentage of the biomass is removed each year. Cereals in...

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...

Earlier seeding generally increases yield

Early spring seeding typically benefits canola yield and quality. An early planting date enables the crop to take advantage of good spring moisture, avoid some heat stress at flowering, and reduce the risk of fall frost damage. Key practice: Crops seeded early (in late April or early May, depending on the region) will out-yield 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,...
