To test the optimum sowing time for long season wheat cultivars uisng three target sowing dates.
Key messages
Early sown, long season material did very well in 2018 considering the season (Growing Season Rainfall was one of the lowest on record).
More options are available to growers who have the opportunity to sow wheat to coincide with earlier rain and the need to start earlier due to a large cropping program.
The trial is planned to run again in 2019 with the aim to test earlier sowing dates than 2018.
