To determine the appropriate sowing time by variety combination to maximise the grain yield and quality of wheat in the WA.
• Match the maturity of a variety with sowing date to maximise the yield potential: – “If sowing early, sow long”.
• Sowing different varieties in order to target the optimum flowering period could minimise the impact of frost or ther end of season stressors. Consider using multiple varieties (with different flowering times and maturities) to target flowering throughout the optimal flowering period for your location.
• Use of long or mid-long varieties in April can increase the diversity of a wheat program that typically consists of >70% short-mid varieties and is geared towards May sowings.
• Performance of varieties with sowing date is compared for Mullewa, Merredin, Katanning and Gibson (EDRS) in 2017.
