The aim of this trial was to compare the performance of very early sown wheat varieties, their early grazing potential and ability to recover from grazing.
Winter wheat (Rosella) sown in mid-March yielded 2.1t/ha, comparable to spring wheat sown in May (2.5t/ha). All varieties provided large quantities of excellent feed, and simulated grazing did not reduce grain yield. Sowing winter wheat in response to late summer and early autumn rain is a successful strategy for overcoming a drier April-May, but varieties adapted to the Wimmera and Mallee are needed
