Cereal response to stubble treatments in Central Western NSW locations
Aims

To investigate the impact that stubble treatments (burning, cultivation, harrowed/flattened or standing stubble) imposed towards the end of the fallow have on the yield of winter crops.

Key messages
  • Burning or cultivating 2015 stubbles tended to produce higher yields, however this was only significant at Ungarie.
  • High rainfall and a soft finish removed the benefit of stored soil moisture that stubble retained systems may have provided.
  • Nitrogen was the limiting factor for both yield and protein for 2016.
  • Growers cannot let stubble negatively impact on weed control and timely sowing.
  • Growers should use crop rotation to their advantage by aiming to sow the right crop into the least antagonistic stubble.
  • Stubble retained systems can require more nitrogen due to increased nitrogen tie-up.
