To determine optimum plant density for hyper-yielding spring canola
• For the third consecutive year there was no response to plant density ranging from target densities of 15 to 75 plants/m² (achieved density in 2022 of 17 to 82 plants/m²).
• There was no significant lodging in 45Y28 RR even at the highest plant densities.
• There was no effect of plant density on grain quality.
• Plant density achieved was higher than targeted. The assumed canola establishment was 65% but establishment achieved was just over 70%.
