Methodology

    Double seeding did not appear to achieve the desired benefits of narrow rowspacing. A great majority of all canola plants came from the second seeding operation.

    Tissue analysis were taken at the early bloom stage and submitted to the Saskatchewan Soil Testing Laboratory for analysis. The results indicated that small deficiencies in micronutrients can be created by the use of extremely high rates of macro fertilizer elements.

    The maturity of Westar was not notably effected by the high fertilizer rates. The Westar appeared to flower longer but the differences in maturity disappeared at swathing time. However, at both locations the Tobin required 4 to 6 days longer to mature with the high fertilizer treatments. Under high fertility both varieties of canola didn't appear to grow much taller but were considerably denser.
