  • Broadcast seeding in April

    Anticipating a very wet spring, some growers are wondering whether to broadcast canola seed while the ground is still frozen. That way, they at least have a chance of getting a crop if the ground stays wet into June. This might work, but beware the following risks: Expect a poor and uneven stand. Canola can […]


  • Blackleg and tight rotations

    A one in four or one in three canola rotation is still the best way to manage blackleg. A one in two year rotation, no matter how one manipulates it, is higher risk. For example, available evidence does not support that a crop sequence of canola-canola-wheat-wheat is better than canola-wheat-canola-wheat. Latest research indicates that blackleg […]


  • Budget for disease management

    Growers working on their canola budgets for 2011 should include disease management costs. Sclerotinia was widespread in 2010 (except in dry regions of the Peace) and sclerotinia spores will be around in big numbers in 2011. With the heavy snow pack, moisture will not be a limiting factor for sclerotia to germinate this spring and […]


  • 90% germ guaranteed for No.1 certified seed

    Growers testing their own wheat and barley seed for farm-saved use have seen some very low germination results — especially if those crops were harvested from regions with delayed harvest due to excess moisture. Some of those growers are wondering about the quality of canola seed. Be assured that No.1 certified canola seed must have […]


  • Larger seed requires higher seeding rate

      Hybrid seed often weighs 5 grams or more per 1,000 seeds. If a grower seeds a 5-gram hybrid at 4 lb./ac. (1,800 grams per acre), that works out to 8 seeds per square foot. At 60% seedling survival, the stand is only 5 plants per square foot. The ideal target is 10 plants per […]


  • Increase fertilizer rates to match yield potential

    In a recent survey on agronomic practices, the Canola Council of Canada found that, on average, growers were applying 79.5 lb./ac. of actual nitrogen, 25.8 lb./ac. of phosphate (P2O5), 4.9 lb./ac. of potassium (K20) and 13.6 lb./ac. of sulphur to their canola fields. This may not be enough for high yielding canola. Canola that yields […]


  • Quick hitters:

    Bins can still heat in cold weather. Based on an informal show of hands at grower meetings, a low percentage of growers have checked their canola bins over the past month while weather has cycled between very cold and unseasonably warm. With all the off quality canola in bins across the Prairies, one can never […]
