To test the grazing recovery of three milling oat varieites, Bannister, Durack and Yallara
Bannister had the highest grain yields with 9.00 t/ha.
Grazing did impact on yield in Bannister, but not Durack or Yallara.
Additional N above the control did not increase grain yields. Based on the trial results, Bannister nitrogen requirement was 25 kg N/t, whereas Yallara and Durack required 35 kg N/t.
Dry matter harvested (simulated grazing) at around GS31 ranged between 0.81 and 0.99 t/ha (NS)
