Is Hindmarsh really a poor weed competitor? locations
Aims

To determine the competitiveness of current and new barley varieties so management packages can be developed for growers to use.

Key messages

Wimmera had the greatest yield loss in the presence of weeds and produced the highest weed yield. Hindmarsh also produced the same weed yield. Both of these varieties should not be sown into weedy paddocks unless there is a good management strategy. Scope, Buloke and Compass were identified as very competitive varieties, with the least amount of yield loss and weed seed production. Generally, the presence of weeds reduced barley yields by 1.4t/ha on a 5.4t/ha crop (mean of all varieties).
