Growers in many regions are reporting canola fields that just don’t look as good as usual. Many are thin stands with weak plants and variable stages of maturity. Here are 10 most likely reasons…

What happens to canola plants that are underwater for a few days? Here’s a detailed explanation from Murray Hartman, oilseed specialist with Alberta Agriculture and Rural Development…

Want to see how a foliar nutrient application helps a hailed crop? Leave a check strip. Want to see whether a novel treatment provided a return on investment? Leave a check strip. Growers can use strip trials on their own farms to test how a particular practice or product performs in a local environment. This information can then be used…

Wet soils cause an oxygen deficiency, which reduces root respiration and growth. Root failure reduces nutrient uptake, and plants will eventually die unless drowned areas dry out quickly… -
Early season hail rarely has an impact on canola yield potential. Hailed seedlings usually come back very well. If hail breaks off both cotyledons or snaps the stem, these plants usually do not survive. But even in these severe cases, while individual plants may die, a whole canola crop is fairly resilient to early season hail when it comes to…

The week after seeding is a good time to dig up seeds and seedlings to check for rots and blights. Disease damaged seed and seedlings die quickly, and may be gone within a few days, which is why this timing is important to an accurate diagnosis. While scouting for disease, also look for… -
Start counting a week after seeding and repeat a couple of times over the following two weeks. Here's how… -
Manitoba and eastern Saskatchewan, in general, have a lower percentage of canola seeded than other parts of the prairie. Canola seeded June 5 or even June 10 in those regions can still produce a good crop, and crop insurance deadlines reflect that. Here are the deadlines…

With an average seeding rate of 5 lb./ac., an average thousand seed weight (TSW) of 5 grams, and 50% seed survival rate, the result is only 5.2 plants per square foot. This doesn’t leave much margin for error — especially given the ideal target is 7 to 10 plants per square foot. Seed with a lighter TSW can improve your…
