To test the target population for irrigated Durack Oats

Key messages

Population had no effect on yield. Populations as low as 130 plants/m2 had similar yields to that of 180 plants/m2.

Plant establishment varies greatly with conditions post sowing. The long term average for cereals at the ICC Trial Block is 70%, but colder soil temperatures and soil moisture can see establishment fall to 50%.
