Seeding uniformity and canola yield locations
Aims

To determine if spacing canola plants more uniformly within the row can improve yield in the WA Northern Region.

Key messages
  • There was a trend of more yield from evenly spaced plants compared to unevenly spaced plants with a 5% improvment at lower plant densities, however this was not statistically significant.
  • Spacing plants more evenly did affect some aspects of plants growth.
  • Canola yields were above 2.5t/ha from low plant density, 10 plants per square metre
