GRDC Demonstration of legumes for reliable profitability in the Western Region - Chickpeas, Dalwallinu locations
Aims

1. To identify the optimal agronomy for chickpeas, grown in medium to low rainfall zones of northern
Western Australia.
2. To address the issue of adequate weed control that impacted the profitability of chickpea crops grown
in medium rainfall zones in earlier trials in this project.

Key messages

• The combined Simazine and Isoxaflutole (Treatment 1) resulted in the lowest early weed counts, with
less than 30 w eeds per m 2 at four weeks post emergence.
• Simazine and Isoxaflutole (Treatment 1) had a profound impact on inhibiting Medic growth relative to
other treatment styles.
• Application of Isoxaflutole & Terbuthylazine (Treatment 2) completely mitigated all weed species
except the medic.
