Plant density for hyper yielding spring canola locations
Aims

To determine optimum plant density for hyper yielding spring canola

Key messages

 There was no significant effect of plant density on grain yield, oil concentration or seed size.
 20 plants/m2 is enough to achieve similar yield to high seeding rates.
