  • Swath later for a big boost in yield

    Harvest and Storage

    Canola fields swathed at 60% seed colour change (SCC) on the main stem can yield 8% more than fields swathed at 30% SCC. That’s according to Canola Council of Canada research from the early 2000s. The yield difference could be even higher with lower plant populations because with fewer larger plants more of the yield will be in the side branches.

  • Scouting and field survey tasks for this week

    Harvest and Storage

    Pre-harvest scouting is a great opportunity to identify late-season insect threats, disease outbreaks and severity and weed escapes. While in the field, you can assess crop stage and harvest timing, and do an end-of-season plant count. Here are a few specifics to look for….

  • Harvest timing for an uneven field

    Harvest and Storage

    Canola fields with large areas at different stages lead farmers to ask the inevitable harvest timing questions: When do I swath? Should I leave it standing for straight combining?

  • Early, hot swathing can increase green counts

    Harvest and Storage

    The combination of swathing canola too early and swathing during a stretch of hot weather can lead to rapid curing that elevates harvest green counts.

  • Late-season hail: Yield and disease risk

    Harvest and Storage

    The later hail occurs in the season, the more damage it can do to yield. Crops not mowed down by hail can see some yield recovery.

  • How to reduce costly harvest losses

    Harvest and Storage

    Canola producers can lose up to five bushels or more per acre if the combine isn’t adjusted properly. Here are tips to measure combine losses and make adjustment to limit those losses, putting more canola in the bin and reducing the volunteer canola seedbank in your fields.

  • Harvest options for multi-stage crops

    Harvest and Storage

    Non-uniform maturation is a common issue at harvest. This issue may be more pronounced in those areas that experienced abnormally dry conditions and intense flea beetle pressure this spring. Swathing remains the best and least risky option to manage uneven maturity.

    Those set on straight cutting have three product options to consider as pre-harvest aids: diquat, saflufenacil (Heat LQ) and glyphosate.

  • Swath timing for higher yield

    Optimal swath timing for canola yield and quality is when at least 60% of seeds on the main stem are showing some colour change and when most (or all) side-branch seeds are “firm to roll.”

  • Time for a mid-winter bin check

    Harvest and Storage

    Extended moments of warmer weather in winter can increase air and moisture movement inside bins. Put a priority on canola with moisture above 8% or higher dockage or green seed levels but take a moment to check in on all bins.

  • Tough or damp canola: Storage risk

    Harvest and Storage

    Canola harvested at 15% moisture may not last long in storage before spoilage begins. How long is hard to predict. If warm, spoilage could start within a matter of days. If stored cool or cold, canola may last longer without spoilage, but this bin will become very unstable with any stretch of warm weather.

  • Snow on canola. What to do?

    Common scenarios growers face with the snow on canola are:
    1. Canola is immature when snow falls.

    2. Canola is ready to swath when snow falls.
    3. Canola left standing for straight combining is hit with snow.
    4. Canola in the swath was already dry and has been hit with snow.
    Here is a description of each scenario, along with some tips to help with decision making….

  • Slow harvest and storage risk

    Harvest and Storage

    When harvest is slowed by rainy, cool days, combining often occurs in short spurts. In those spurts, the first and last loads of the day are often tough. This can mean an increased storage risk. Condition these bins with aeration to even out moisture and temperature. Consider filling bins to only two-thirds capacity to allow for improved air flow.

  • Frost hits standing canola. What to do?

    Harvest and Storage

    You have two choices in this situation: Swath now or wait.

    Swathing now might prevent further seed loss if severe frost damage will soon cause pods to pop open and pedicels to snap. You could have shriveled seeds and high green counts, but that might be better than the potential losses from waiting. But if frost did not kill the plants, swathing early will halt any upside potential you’d have from leaving the crop standing to fill out more seeds and clear more green.
