N canola seeding rate locations
Aims

To determine the effect of canola plant density on nitrogen (N) response.

Key messages
  • 2 kg/ha seeding rate produced a plant density of 37 plants/m2; 4 kg/ha seeding rate 68 plants/m2
  • Canola plant density had no effect on Nitrogen response
  • 2 applications of 80Kg/Ha NS41 increased yield from 1.34 to 1.70 t/ha
  • Plant test results showed low Boron (B) levels (about 14mg/kg) at the 6 leaf stage but there was no response to Bortrac 150 applied at early flowering.
  • Large number of ryegrass plants, particularly in 2kg seeding rate plots.
