When growers have canola stands of fewer than 4 plants per square foot — due to low seeding rates, poor seed survival, insects, crusting, frost, wind, etc. — they grapple with the question whether to reseed. An established canola stand with as few as 1-2 plants per square foot generally has higher economic potential than if were to reseed that… -
After a frost, it can take a few days to accurately determine how many plants survived, and whether the stand is still uniform. Be patient before making any decisions. Check the whole crop the day after a frost and then again 3-4 days after a frost to assess the situation… -
Canola is quite susceptible to water logging and shows a yield reduction after only 2-3 days in excessive moisture. Wait to see how the crop recovers before making decisions on reseeding or fertilizer top ups… -
Growers will learn a lot from two field checks during the first few weeks after emergence. Scout fields 5 to 10 days after seeding when canola starts to emerge, looking for early threats. Then go back again two to three weeks after seeding to assess the stand… -
Residue management to improve canola seed placement is best done in the fall with a well set combine and, if necessary, with harrowing. Residue issues in spring are more difficult to manage, given that straw tends to be cool and tough. Waiting for sunny and warm conditions will allow straw to break up and spread, improving results from harrowing… -
While growers wait to hit the fields, this is a good time to pull out the drill and give it a good inspection. A large flat concrete pad is ideal for leveling… -
How to get the drill ready for spring: Level side to side and front to back, check each opener for wear, check shank trips, inspect all moving parts, inspect electronics, and do a sock test to make sure the air delivery system is not cracking seed… -
An important factor in canola stand establishment next spring is the crop residue situation this fall. An even mat of cereal residue is preferable to clumpy distribution that can affect drill performance, seed survival and overall crop uniformity next year. Fall is the best time to make sure residue is spread evenly. A properly adjusted combine straw chopper and spreader…
