Managing early sown wheat locations
Aims

To investigate the suitability of new and pre-release winter wheat varieties to the Wimmera and Mallee, and define their optimal time of sowing.

Key messages
  • March to April sown winter wheats performed comparably to main season spring wheats. Optimal time of sowing for winter wheats was late March to mid April.
  • Early sowing may present opportunities to increase overall farm profitability by spreading the sowing window without excessive risk of frost and heat.
  • Longsword (RAC2341) failed to perform at both sites due to unexplained sterility.
