Optimising cultivar and time of sowing in wheat locations
Aims

To investigate time of sowing for individual wheat cultivars with different maturities.

Key messages
  • Despite damage from frosts, the highest wheat yield in this trial came from Trojan sown in late April at Hart.
  • Based on two years of trial data across SA, Trojan complements Mace in a cropping program and allows growers to sow earlier and achieve higher yields (0.7 t/ha) than could be achieved with Mace alone.
  • Across nine trials in SA (2014 and 2015) there was an average yield penalty of 28 kg/ha per day for every day sowing is delayed past the end of the first week of May.
