1. Canola Planting
Brad True

2. Seed Bed Preparation Canola is very susceptible to soil crusting
Seedbed must be firm
Seed and soil moisture is critical for rapid seed emergence so seeding in dry soil is not recommended
Seedbed should be prepared in a way to prevent wind erosion since seedlings are easily damaged by drifting soil
Harrowing is not recommended

3. This is a pulvi mulcher

4. Seed bed cont’d Can be planted with a variety of equipment
Optimum planting depth is between ½ inch to 1 inch deep
Canola is typically seeded in 6 to 7 inch rows with a grain drill.

7. Fertilizer Application
Nitrogen and Sulfur are key elements for high yields
Nitrogen or potash shouldn’t be applied in direct contact with seeds but should be applied in a band at least 2 inches away from seeds
Soil test is recommended for proper needs
Low Sulfur can be the difference between having a crop and not having a crop

8. Fertilizer Cont’d
Canola takes up Sulfate-S and sulfur fertilizer may be ammonium sulfate or a blend of ammonium sulfate and degradable elemental S
Blend is recommended because in sandy soils, sulfur may leech during early season rains while elemental S may degrade during a moist season to supply needed S later in the year.

10. Seed Rates 5-8 pounds per acre for Argentine Type
5-7 pounds per acre for Polish type
There is a major difference in seeds per pound in varieties
Argentine contain 75,000-85,000 seeds per pound
Polish is 135, ,000 seeds per pound
Optimum plant population of 16 plants per sq. ft or 600,000 plants per acre w/o herbicide resistance
As low as 2 plants per sq. ft with herbicide resistance (uniformly spaced)

11. Dormant Seeding Defined as planting canola in cold, nearly frozen soil
Seed stays dormant until Spring
Plant when the top 2 inches of soil are or below 32 degrees
If soils warms to around 38 degrees the seeds germinate and will be killed once it freezes again
Very difficult to do

12. Planting Timing April to early May
Planting beyond May 15 will decrease yield potential
Planting in June will significantly reduce yield
Planting in May will reduce risk of heat and drought stress during flowering
Canola is frost tolerant and can tolerate temperatures as low as 24 degrees

13. Different Varieties Argentine Type Polish type Higher yield potential
Taller
Higher oil content
95 Days to maturity
Polish type
80 days to maturity
15-20% less yield than Argentine
More resistant to shattering
Yellow-brown seeds with less chlorophyll

14. Herbicide Resistant Canola
Clearfield Resistant-use Beyond herbicide at a 4 fl oz/A Post to Imi-tolerant canola from emergence until prior to bloom to control most annual grasses and broadleaf weeds
Liberty Resistant-34 fl oz/A Post from cotyledon stage to bolting stage controls most annual broadleaf weeds, controls or suppresses grasses, and may suppress perennial weeds.
Roundup Resistant- applied at 1 pt /A with no more than 2 applications from emergence to bolting. Controls most annual and perennial weeds.
