Winter canola is a new crop for the northern regions of the
Eastern Corn Belt. Fall establishment has been a problem, which may contribute
to lower grain yields. It was hypothesized that management practices, such as
increased seeding rate or the use of fungicide-treated seed may increase grain
yields. To test this hypothesis, the variety ‘Wichita' was established in two
northern Ohio sites and one northern Indiana site in the fall of 2005 and 2006.
Experimental design was a two-factored randomized block replicated six
times. Treatments included three seeding rates of 6.7, 10.1 or 13.4 kg
per ha with or without a commercial fungicide. Even though there were three
significantly different populations, yields were not affected by seeding rate
or the use of fungicide-treated seed.
