Weed competition - determining best management practices in durum wheat locations
Aims

To identify the most effective alternate techniques and discover the impacts they have on weed control, yield and grain quality

Key messages

DBA Aurora and Mace showed similar ability to compete with weeds in 2014. Using higher seeding rates improved weed control. Increased crop seeding rate resulted in reduced crop screenings in 2014
