This article summarises the results of precision planting technologies at Hart for canola between 2018 and 2021
• Data collected across four years of trials suggest that precision planting of canola provided an average yield benefit of approximately 10% compared to conventional sowing.
• Yield benefits from precision planting tended to be greater at low plant populations.
• Precision planting significantly improved the uniformity of canola stands, although it was still well below the ideal uniformity of a perfect placement.
• Precision planting of canola could allow a reduction in plant density without a loss of grain yield, with potential savings on seed costs of $24/ha, confirming grower experiences to date.
