Sowing date effect on flowering and grain yield of eight canola varieties – Leeton 2019 locations
Aims

This experiment was designed to increase the understanding of:
• canola yield potential in the high yielding irrigated zone of southern NSW
• the effect of climatic stress at different canola growth stages.

Key messages

• In a season characterised by low frost severity, Nuseed Diamond was the highest yielding variety for all three sowing dates.
• In a low frost severity season, earlier sowing on 27 March and 11 April achieved a higher grain yield compared with the later sowing on 30 April.
• Triazine tolerant varieties were generally lower yielding compared with other varieties with a similar phenology.
• Winter type canola yield and oil performance were comparable with spring types when sown before mid April and could be worth considering as a dual-purpose crop due to the additional value generated from grazing.
