Abstract

• Both barley varieties out yielded wheat by approximately 1000kg/ha in all treatments

• Barley yields responded to the highest rate of early post emergent nitrogen (75kgN/ha) with wheat yields plateauing at the 50kgN/ha rate

• Ryegrass biomass was two to three times higher in wheat than barley, and this may have significantly reduced wheat yield
