Cereal variety x weed competition – Trangie 2014

Abstract

Key findings • The barley varieties Compass [PBR], La Trobe [PBR] and Scope CL [PBR] were the highest yielding varieties in this trial in the presence and absence of weed pressure. • Increasing the plant population of La Trobe [PBR], and Scope CL [PBR] improved their relative yield where weeds were also present by 15% and 6%, respectively and further reduced weed seed‑set. • La Trobe [PBR], Scope CL [PBR] and Compass [PBR] were the most competitive varieties and provided greatest suppression of weeds. • Barley was generally more competitive with the mimic weed than wheat but large differences were apparent between varieties.
