The number one risk: Neglected bins. Growers are busy enough at harvest just getting the crop off, but take time to check all bins within the first two weeks after filling, and then again a couple more times until the canola is cool and winter sets in. Canola seed continues to sweat during the first 4 to 6 weeks after…

Cutting canola hot can lead to fast dry down, which can trap green in the seeds. If canola green counts are still high (No.1 canola requires 2% or less) and seed moisture levels have dropped below 10%, further green clearing is unlikely...unless conditions change. Canola seed moisture needs to get back up to 20% with temperatures remaining at 15°C or…

Swathing canola when temperatures are hot can cause two potential problems for the crop: 1. Rapid dry down due to hot conditions does not give the green-clearing enzymes enough time to reduce chlorophyll levels in the seed, and green counts can be elevated. 2. Very dry pods can shatter if swathed on a hot day…

Canola binned hot, even if it has low moisture, low dockage and low green, should still be put on aeration. This will even out the temperature throughout the bin, and help remove some of the moisture from respiring seed. Even at low moisture, air movements within the bin could concentrate this moisture…

Research conducted by the Canola Council of Canada over approximately 28 site-years indicates that significant yield increases can be achieved by waiting until 50-60% seed colour change on the main stem before swathing. Swathing at 50-60% SCC resulted in 8% more yield than swathing at 30-40% SCC, 12% more yield than at 10-20% SCC, and 19% more yield than swathing…

Canola destroyed by hail could be harvested as forage, replaced with a short-season barley silage crop, or turned under for green manure…

Growers can plan at this time of year to make sure they have enough seed purchased to achieve the target plant stand of 7-10 plants per square foot, which will provide a more uniform-maturing stand and a lower green count. Also, take note of the maturity ratings for each variety…

Growers with dry canola and high green counts are wondering whether to leave the swathed crop a while longer or combine now and accept the grade loss. When making that decision, ask: Is moisture in the forecast? How green is it? What's the price discount? These and other considerations will help with the decision…

Canola with high chlorophyll content is less stable in storage, even if the canola is dry and cool. The safest bet is to deliver sooner than later. If that is not an option, proper conditioning and frequent monitoring for heating and spoilage are crucial until it can be delivered…
