wheat crop maturity

Catalogue: GRDC Media
Pioneering Western Australian research into techniques to control weed seeds in grain paddocks at harvest time has received international recognition... Dr Walsh said the research, funded by the Grains Research and Development Corporation (GRDC), proved that a high level of weed seeds is retained at wheat crop harvest time, providing further evidence of the effectiveness of harvest weed seed control (HWSC) in preventing weeds from replenishing the seed bank... "The research demonstrated that the four dominant annual weeds of Australian cropping systems - annual ryegrass, wild radish, brome grass and wild oats - retain 77 to 95 per cent of their seeds above a harvest cut height of 15cm at wheat crop maturity," he said...

With harvest in full swing, many growers are putting into practice harvest weed seed control (HWSC) systems to help tackle weeds - which are at high levels this season... Many growers are probably already familiar with the HWSC options of narrow windrow burning, chaff carts, the Harrington Seed Destructor and the Bale Direct system (baling all chaff and straw material as it exits the harvester)... The chaff deck places the chaff exiting the sieves of the harvester on to permanent wheel tracks, and it is estimated that up to 70 of these units are being used across WA's South Coast region this harvest...
