Growers will be eager to seed with the return of warm weather but early weed control also remains a priority — especially for fields that have not received any yet. Spraying those fields now and seeding three days later will have an economic benefit given that weed competition remains a major factor in crop yield potential… -
Seeding early May versus late May or early June, providing that crop conditions allow for it, is a relatively low cost way to increase yield and profit from the crop… -
Yield potential for canola seeded in late May is not as high, generally, as canola seeded in early May, but it is still pretty good and better than for canola seeded in June. Given the current date, the argument in favour of reseeding a crop clearly thinned out and set back by frost or any other issue may have more…
