Early seeding usually improves canola yield potential and quality, in large part because earlier crops tend to flower before the hottest days of summer. But the yield benefits of early……

Very early seeding increases the frost risk and may not provide a yield advantage over your regular early seeding date. Early seeding usually improves canola yield potential and quality, but these benefits depend on survival of a sufficient plant population — ideally 7 to 10 plants per square foot, and a minimum 4 to 5. An early-seeded crop that is…

This graph shows that a higher seeding rate that will ensure a stand of at least 60 plants per square metre (6 per square foot) will mature a lot earlier than a stand with 20-40 per square metre. A higher seeding rate is just one way to reduce the days to maturity for a late seeded canola field…

It’s mid May, so put away the soil thermometer. When you get the chance to seed, then seed. Seeding into warmer (8-10°C) soils will improve seed survival and have more seed emerging at the same time (as shown in the graph) but this needs to be balanced against the benefits of early seeding. To improve seed survival and speed of…

Early weed control is an important step in profitable canola production. Research on preseed weed control showed that early seeding was less important to yield than early weed control. Pre-seed weed control will manage weeds that emerge ahead of seeding, reducing crop competition for light, moisture and nutrients…

Growers hoping to seed their final canola acres this week or next week may want to consider the following tips to deal with a shortened growing season…

Canola benefits from both early seeding and early weed control. The solution: Work through seeding and spraying operations simultaneously. Have the seeder working when it can. Meanwhile walk fields to get an indication of weed pressure. Fields with large numbers of winter annual and perennial weeds should get a pre-seed burnoff. While spraying that field and waiting 3 days to…

Seeding earlier increases the chance of a killing frost on seedlings but it also limits the chance of heat stress in summer. When seeding early, take steps to improve crop establishment by seeding shallow, aiming for at least 7 plants per square foot, and using seed-placed phosphate for faster pop up. If weeds are emerging and growers plan to wait…
