To determine the correct maturity timing required in chickpea for successful crop topping practice.
Key messages
The wet season finish in 2010 favoured chickpea production, however this made timely
weed control through crop-topping very destructive.
There was little varietal response from crop-topping in 2010.
All varieties showed reduced yield when crop-topped at or before the recommended timing
for optimum ryegrass control (milky dough stage).
Crop-topping 2 weeks after the recommended timing was the only timing considered “safe”
for chickpeas in 2010, with only one variety showing reduced grain yield and one variety
having reduced grain weight.
These results emphasise the difficulty in employing this weed control method in chickpea.
