SAC C21-26 Spring Plant Density (45Y28 RR) locations
Aims

To determine optimum plant density for hyper yielding spring canola.

Key messages

 Yield was lower for the 15 plants/m² target population (15.6 plants/m² actual population) than the higher population targets of 30 to 75 plants/m².
 The penalty of the low population was close to 1t/ha.
 This is the second year with a similar response at the SA site, suggesting that plant population targets should be higher than other hyper yielding crops environments.
 Winter is relatively mild at Millicent (maritime environment with high minimum temperatures) and development is rapid but with short days and low light intensity during winter growth is slow. Increasing plant population from 15 to 30 plants/m² may be a useful
tactic to ensure enough vegetative biomass to reach full yield potential.
