Seeding date decisions are often driven more by historical frost risk than present conditions. That is why many growers will not seed canola before May 1, even if their area had what seemed like favourable seeding conditions in April. Historical frost risk can be interpreted differently based on the crop’s frost tolerance and the grower’s appetite for risk…

If you have perfect seeding conditions in late April, should you seed canola? Early seeding usually improves canola yield potential and quality, but these benefits depend on survival of a……

If perennials, winter annuals and early emerging weeds — like this stinkweed — are growing, there is no benefit to waiting for later emerging weeds such as lamb’s quarters or redroot pigweed to show up. Weeds present now will have a greater impact on yield than weeds that emerge with or after the crop…

In dry soil conditions, growers may be tempted to seed deep enough to reach moisture. This is not necessary from April to mid-May. The common recommendation to seed no deeper than 1” still applies in dry conditions. Here’s why…

Growers with dry soil conditions may be tempted to reduce fertilizer rates. After all, if crops do not reach yield potential, reducing the cash outlay at seeding may mean that a lower-yielding crop could still be profitable. However, when it comes to canola in particular, fertilizing for average or target yields in spring is often the most economic practice —…

Make sure soil is cleaned off any used equipment recently purchased from areas known to have clubroot. This is good biosecurity practice. Ideally, this should be done at the purchase location before bringing it home…
