Yield and cost implicatios of seed size in shallow planted canola locations
Aims

To confirm if seed size has any significant effect on yield in shallow seeding (15-20mm) situations that are common in WA's sandy soils Determine the economic implications on seed size assuming yield is the same.

Key messages
  • Seed size did not have a significant effect on Canola yield when planted 15-20mm deep.
  • Cost differential of establishing a Canola plant stand can be substantial.
