Effect of sowing date, seeding rate and irrigation pre-sowing on grain yield of two canola varieties - Condoblin 2015 locations
Aims

To determine which management factors for canola improved the efficiency of using stored water.

Key messages
  • The combination of extra stored water (20mm) and early sowing (17 April) resulted in the highest grain yield in this experiment.
  • Early sowing without extra stored water gave a higher yield than late sowing (4 May), regardless of teh irrigation treatment at the later sowing date.
  • The extra grain yield from early sowing and irrigation was due to increased biomass accumulation and imprved harvest index.
  • Oil concentration was low overall, but was higher from the early sowing (33.6%) than th elater sowing (30.5%).
