Results from the two years of trials are shown in Figure 1. The 2014 trial, sown on 30 April, showed a significant increase in yield of 200kg/ha at the largest seed size compared with both the small and medium-sized seed.
The 2015 canola sown on 16 April did not show any significant differences, due to high variability within the trial. However, the medium and large seeded canola sown on 29 April yielded significant more than the small seed. The yield increase with large-size canola over the small-seeded canola was 310kg/ha.
The results on vigour have also been consistent and remarkable in the trails, with visual differences evident (Figure 2).
