Abstract
All cereals (wheat, barley, oats) displayed the ability to recover from extreme frost events at stem elongation through re-tillering.
Match phenology to sowing dates to begin flowering when the frost risk has passed is critical to yield formation.
However, stem elongation exposure to frost is also important to yield development.
Urambie barley was consistently higher yielding than all other varieties from all sowing windows.
Sowing fast varieties (LaTrobeA, Emu RockA, ScepterA) later increased yields compared to early sowing.
Oat varieties benefitted from later sowings through increases in both yield and grain quality.
