Agronomic adaptions to a changing climate locations
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.
