Abstract: In 2000 a hybrid canola seed harvest management study was undertaken to determine the potential use of a desiccant as a harvest aid treatment compared to the traditional method of swathing. Three treatments, two rates of desiccant (Reglone) and swathing, were applied to an argentine A line (female parent) of canola. The treated canola was then harvested at three moisture levels (15%, 12.5%, and 10%). Data collected were yield, seed vigor, germination, actual harvest moisture, and thousand seed weight. The desiccated treatments dried significantly faster than the swathed treatment suggesting harvest could commence earlier in the fall if farmers used desiccant on a commercial scale. A second study was conducted over an extended period of time to evaluate the effects of delayed harvest on germination and seed vigor. Delayed harvest depressed vigor more than germination.
