Abstract
Weed seed head trimming or cutting weeds above the crop prior to weed seed maturity may be useful in reducing the number of weed seeds set if the weed seed is above the crop canopy and the cutting height is controlled. Indian hedge mustard (Sisymbrium orientale) seed collected in the 2005 chickpea harvest samples was reduced by around 35% with all trimming treatments. In 2006 the late flower trimming reduced the seed number of wild oats and volunteer wheat in chickpeas. Lupin and chickpea grain yield was slightly reduced by trimming in 2005 but with better height control did not reduce yields in 2006. Given the difficulties in controlling weeds by the growers due to widespread development of herbicide resistance in these weeds within the WA wheat belt, this novel non-chemical way of weed control is a viable promising option to reduce the soil weed seed bank.
