It should be noted that most fields in Missouri are unlikely to need sulfur or boron for canola production. Canola is generally planted between late August and mid-September in Missouri. Sept. 15 appears to be an optimum planting date in central Missouri. Date of planting is critical for canola, because the plant must reach the eight to 11 leaf stage before a killing frost to develop winter hardiness, yet it must not grow excessively. Existing small grains equipment can be used to plant canola, but the seedbed must be more uniform and trash-free than for wheat.
Excessive trash can cause uneven germination and weed problems.
Canola is a small-seeded crop and should be planted shallow. A seeding rate of 6 to 8 pounds per acre is recommended. Row spacing is usually 7 to 10 inches. The narrow rows and high seeding rate allow the plant canopy to cover the soil quickly and provide better competition for weeds. When a good stand of canola is established, the dense growth of leaves usually makes the crop a strong competitor against weeds.
