Aims

In 2012 the UNFS attempted to validate this early work conducted by the CSIRO. Seed of a long season variety Eaglehawk was sourced. This variety is Prime Hard Quality in NSW and so would be AH in SA.The aim was to conduct a time of sowing trial using three varieties at three times of sowing:- an early maturing variety (Axe), mid season maturing (Frame) and late maturing (Eaglehawk). Ideally the three sowing times were to be 1) mid April 2) early to mid May and 3) early to mid June.

Key messages
  • Slow maturing varieties sown early have potential to increase profitability, even in low rainfall areas.
  • The late break to the season in 2012 in the UN, did not allow the long season variety to perform.
  • Dry sowing of wheat 5 weeks before the opening rains produced equal or higher yields to wheat sown on the break.

Other trial notes

The time of seeding trial was sown after good falls of rain in January and March had increased soil moisture levels in the top 40 cm. Soil testing completed after harvest showed that the earlier establishing dry sown crop had about 7mm less residual water in the soil profile. This is likely due to greater root development allowing increased exploitation of the soil water reserves.
