To investigate management options which reduce the risk of failure when growing wheat on wheat, or barley on wheat stubble.

Barley can be successfully grown on retained wheat stubble, but it is advisable to burn wheat stubble when growing wheat on wheat. If stubble is retained then Yellow Leaf Spot can be a devastating disease in a wet winter. The most important management practices when growing a cereal on cereal are as follows:

• Select paddocks with low numbers of grass weeds.
• Retain wheat stubble for barley, burn the stubble for wheat.
• Control summer weeds to ensure summer rainfall can be used by the crop.
• Use varieties with good disease resistance such as Silverstar or Krichauff.
• Disease - select paddocks with low disease pressure (monitor the previous crop) and DNA test the paddock prior to sowing.
•  Apply sufficient nitrogen for a good crop (soil test to know how much to apply).
• Barley on barley can lead to serious problems with leaf diseases such as net blotch.
