Brush up on green-seed counting

2010 - Issue 19

Harvest

With uneven maturity and later canola crops, this will be another year to watch green counts.

Here are some tips to follow when testing for green seed:

  • Rather than start up the combine to take a sample, insert a scoop shovel underneath the swath and use your hands to thresh pods near ground level into the shovel. These plants will have cured more slowly and if any plants have higher green counts, it will be these ones.
  • Collect the seeds, put them into 100- or 500-count test strips and roll them out.
  • Do a few strips and come up with an average. Five green seeds out of 500 represents 1% green.
  • Repeat this a few times through the field, making sure to check hillsides and flats rather than hill tops and field edges, which tend to be thinner and more advanced.
