INTRODUCING A NEW OIL SEED CROP TO OHIO -- WINTER CANOLA.

- Abstract
Winter canola (Brassica rapa L.) is a potential new crop for Ohio. Grain yields may be affected by stand establishment problems and/or winter survival. 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 at two Ohio sites (near Custar and Fremont) in the fall of 2005 and 2006. Experimental design was a two-factor randomized block replicated six times. Treatments included three seeding rates of 6.7, 10.1 or 13.4 kg ha-1 with or without a commercial fungicide, HELIX XTRA. In 2006, yields were 4477.3, 4431.4, and 4297.1 kg ha-1 at Custar and 2414.2, 2481.5, 2556.8 at Fremont for the 6.7, 10.1 or 13.4 kg ha-1 rates, respectively. Only the Fremont site, which had grain yields of 2263.9, 2353.1 and 2270.2 kg ha-1 for the 6.7, 10.1 or 13.4 kg ha-1 rates, respectively, survived the winter in 2007. In 2006, yields from fungicide-treated seed were 4399.6 kg ha-1 and 2505.2 kg ha-1 and yields from untreated seed were 4404.3 and 2463.1 kg ha-1, at Custar and Fremont, respectively. In 2007, yields were 2281.1 for treated seed and 2311.6 for untreated seed at Fremont. An ANOVA test (p=0.05) showed yield means were not statistically different among the three seeding rates or between the means of treated and untreated seed. Results suggest that Ohio producers should not expect an increased yield response to larger seeding rates or the use of fungicide-treated seeds.
