Birchip, VIC
Aims
To trial and demonstrate two possible agronomic adaptations to a changing climate:
to sow wheat varieties earlier to reduce the possibility of heat shock events during grain fill whilst taking into account the frost risk, and
to sow more than one variety in the one paddock as a mix to ensure that the whole crop is not susceptable to frost and heat shock at the same time.
Key messages
Sowing too early exposes a crop to a high frost risk at flowering.
Sowing too late exposes a crop to heat shock during grain fill.
Use Yield Prophet to determine the least-risk sowing window for the varieties you are planning to sow in 2011.
