Plant density for hyper yielding winter canola locations
Aims

To determine optimum plant density for hyper yielding winter canola

Key messages

 Plant densities achieved were generally within 10% of target plant densities.
 Vegetation assessments (NDVI) showed little differences in vegetative biomass of the two higher plant densities, with the 30 plants/m² density also coming close to the two higher densities by late winter.
 The low density (15 plants/m²) treatment was always lower on vegetative biomass than the three higher treatments.
 Yield of the 15 plants/m² target treatment was 0.73t/ha lower yielding than the 30 plants/m² target treatment.
 There was no impact of plant density on any grain quality parameter.
