Effect of lime and herbicide on the control of annual ryegrass in a wheat-wheat-lupin-barley rotation locations
Aims

A four-year study has investigated if lime applied in a low pH soil could enhance the efficacy of herbicides on weeds (ryegrass and barley grass) and improve crop performance in a wheat-wheat-lupin-barley rotation at the Wongan Hills Research Station, Western Australia.

Key messages

Three years after application of lime, soil pH (CaCl2) increased by 0.68–1.45 units at 0–10 cm depth, 0.20–0.47 units at 10–20 cm and 0.08–0.18 at 20–30 cm depth. • Lime reduced density of ryegrass by 42% and barley grass density by 67%, improved barley crop vigour by up to 13%, and increased barley grain yield by up to 7% in 2013. • Boxer Gold in 2013 season together with Sakura and simazine in previous seasons reduced annual ryegrass density by 96% and barley grass density by 99%, improved barley crop vigour by up to 15%, and increased barley grain yield by up to 16%. • Lime effect on efficacy of herbicides in controlling weeds was not evident.
