Frost Tactics 2 Trial 2: Cereal moderate frost risk locations
Aims
  • To improve understanding the relationship that frost timing has on varietal phenology and time of sowing
  • To determine the relative risk of growing wheat compared to barley in high and moderate frost risk areas. 
  • The plan is to combine with data collected in 2022 and 2023 to determine EP x frost risk tool
  • To determine if there is any benefit in mixing varieties of differing phenology as a tool of evading frost 
Key messages

Choosing varieties with a phenology that shifts flowering away from when a frost is likely to occur, can reduce frost damage/risk.

Tooligie Hill 2024 Barley

Sow date Not specified
Harvest date Not specified
Plot size Not specified
Plot replication Not specified
Other trial notes

With very small differences in varietial tolerance to frost, one of the easiest management decisions a grower can make in a frosty area is to plant a variety that will flower outside the tradtional frost window. However there is still need to understand the drivers of phenology with the latest varieties and differing sowing times.
