Field Notes: Harvest Management

Straight cutting canola is gaining in popularity as the thought of eliminating one more operation on the farm seems attractive to most people. But what hybrids are best adapted to this practice? We tested L140P, Nexera 2022 CL and 75-65RR and wanted to determine the durability of the plant when left out in the field and/or treated with a harvest aid. Of the three hybrids tested L140P definitely had the least pod shattering, while the other two only had a few shatterings. We saw very little difference in whether the harvest aid was glyphosate + Heat or Reglone Ion. However, the use of a harvest aid certainly increased the speed of harvesting over the untreated, unswathed plot, especially with L140P and 75-65RR.

While each year and each unique situation can produce varying results, it’s suffice it to say that the practice of straight cutting canola is here to stay and we will continue to evaluate new hybrids and harvest management practices.
