The key harvest management issue with snow on standing canola concerns not so much the precipitation (although heavy snow can cause lodging) but the frost that comes with it. The common scenarios growers face with the snow on standing canola are: 1. Canola is immature when snow falls 2. Canola is ready to swath when snow falls. 3. Canola left…

The ideal swath timing is when 60% of seeds on the main stem are showing some colour change from green to brown. However, various factors complicate the swath timing decision, including frost and uneven crops due to hail. A few other scenarios surfaced this week, including late starts, disease and lodging (shown above)…

Growers have three steps to assess combine losses: 1. Measure the losses. Drop pans are required, given that combine loss monitors are not always accurate or calibrated properly. How to measure losses. 2. Determine whether those losses are acceptable. 3. If not acceptable, take measures to reduce the losses. Les Hill is the manager of technical services and business development…

An important factor in canola stand establishment next spring is the crop residue situation this fall. An even mat of cereal residue is preferable to clumpy distribution that can affect drill performance, seed survival and overall crop uniformity next year. Fall is the best time to make sure residue is spread evenly. A properly adjusted combine straw chopper and spreader…

Excess moisture has caused some canola to sprout inside pods. There is not much growers can do to avoid this, and combining early is not an option — given the storage risk. Sprouted seed is categorized as “damaged” seed, which is a grading factor. No.1 canola can have a maximum 5% damaged seed. No.2 can have up to 12% damaged…

Swathing too early and in hot windy conditions can contribute to high levels of green seed. Cutting canola in hot conditions leads to rapid dry down and desiccation, which doesn’t give chlorophyll time to clear from immature seed. Waiting until less mature seed is at least firm to roll between thumb and forefinger will help minimize yield reductions from early…

The swath decision becomes more difficult in crops with plants at multiple stages of growth. For example, if some plants are at 60% seed colour change (SCC) on the main stem and other plants are still flowering, growers may want to hold off on swathing. Or if plants are large with many secondary stems, the main stem may be at…
