Abstract
Incorporation of effective crop rotations for supplemental weed control has been shown to reduce the growth and establishment of annual weeds and deplete the weed seed bank in broadacre cropping systems. Long term rotational trials were established in 2014-2018 to quantify the impact of strategic management practices upon weed infestations, with a focus on key winter annual and summer fallow weeds, in the moderate rainfall zones of the Riverina in NSW. Trials were designed with grain, dual-purpose and pasture crops to determine if weed management is facilitated through successful manipulation of crop rotational and cultural practices by evaluating weed seedbank dynamics over five growing seasons. Weed seedbank dynamics were assessed by sampling the soil seedbank, and recording weed emergence in a glasshouse over an 18 month period following collection. Weed suppressive rotations included a series of cereal and break-crops, while the weediest rotation contained dual purpose and pulse crops.

| Other | The theme of the conference is System Solutions for Complex Problems. The theme underpins the need to strengthen collaborations between practitioners and researchers from a wide range of disciplinary backgrounds to address increasingly complex problems and uncertainties. So, the question is not If, but when and how, multidisciplinary collaborations will be developed. The 20th Australian Agronomy Conference will feature leading international and national speakers addressing issues such as the need to foster soil biology for enduring profitability, carbon sequestration, herbicide resistance, and the interwoven relationships between food production, energy and the environment. We will discuss and share our latest research findings amongst circa 300 agronomists from Australia and the world, as well as farmers, consultants, agribusinesses and farmer peak bodies. |
