Effect of wild oats on grain yield of barley locations
Aims

To measure the impact of increasing wild oat (Avena fatua) densities on the grain yield and quality of barley.

Key messages
  • 20 to 25 wild oat plants per square metre caused a 50% loss in barley grain yield.
  • High wild oat densities significantly reduced barley grain size from (43 to 28 mg).
