It isn’t only luck that pushes a canola plot to 102 bushels. Nor is it only nitrogen.
It is the precise nutrient ration developed over five years of research.
The Canola 100 project exceeded 100-bu. canola in 2020 for the third time.
Although the nutrient package has been slightly different each time, it’s becoming clear to Canola 100 agronomist Troy LaForge that he is on the path to replicate the ingredient package that’s producing these yields.
LaForge said, “One hundred bu. canola has been achieved in single blocks of plots. It hasn’t been replicated yet, but it is becoming clear how we do it.

Some Manitoba oat growers are still using chlormequat chloride — the active ingredient in Manipulator —and sometimes to measurable success.
One irrigated block in 2020 at Broderick Sask., received the following management:
- Soybeans-wheat-canola rotation with no residual herbicides from previous years.
- Soil pH 6.8, tested medium for available phosphorus and adequate for potassium and available potassium.
- The variety Brevant 3010 seeded at seven plants per sq. foot, treated with Quickroots and Jumpstart.
- Plot was seeded with a Seedmaster air drill on May 29 at 1.25 inches.
- Fertilizer was broadcast before seeding with 100-50-10-14, using Amidas as nitrogen source
- Fertilizer was sidebanded at seeding using 60-60-50-40 0.5 B 0.5 Cu 1 Zn. Amidas was the nitrogen source. Conventional MAP, KCl and granular sources of micronutrients were available in the sulfate form. Four gallons per acre of Alpine G22 with 0.5 litres per acre of Mn, 0.5 litres per acre of Zn and 0.25 litres per acre of boron in seedrow.
- Fertilizer was broadcast at rosette stage with 100-0-0-14 using Amidas.
- Plot was sprayed with Liberty at the two- to three-leaf stage sprayed at 1.6 litres per acre plus Centurion and 2.0 litres Alpine G22 plus one litre per acre of Rogue 2.
- Crop was sprayed twice for sclerotinia at the 20 percent and 50 percent bloom stages.
- Yield 102 bu. per acre.
