Ripper idea to engineer soil fix
Issue 153, July-August 2021 - 2021-07-02T09:00:00+10:00Dreaming big, researchers and a machinery manufacturer have developed a ripper that can ameliorate soils at depth, an important part of a transformational soils project

Barley breeding lines gain crown rot resistance
Issue 153, July-August 2021 - 2021-07-01T09:00:00+10:00Three different sources of resistance to crown rot have been combined in barley elite lines destined for each grain growing region, with a fourth in the works and more resistance gene discovery work underway

Multi-pronged trials road test intercropping
Issue 153, July-August 2021 - 2021-06-30T09:00:00+10:00New research is examining the potential for intercropping – the age-old backyard practice of growing two or more crops together – in broadacre cropping systems across the southern grains region. The statewide Victorian study is road testing the productivity and profitability of several approaches to intercropping compared with monoculture cropping as part of the Victorian Grains Innovation Partnership (VGIP).

Researchers refine tactics to slow feathertop Rhodes grass spread
Issue 153, July-August 2021 - 2021-06-29T09:00:00+10:00Feathertop Rhodes grass seeds are 10 times lighter than annual ryegrass seeds, which explains why the weed has spread so quickly across Australia, prompting regional research and the development of locally relevant management packages

Wild wheat relative leads to crown rot gene discovery
Issue 153, July-August 2021 - 2021-06-28T09:00:00+10:00Wheat lines containing a crown rot resistance gene have arrived in Australian quarantine, with pre-breeders standing by to test the resistance and combine it with four other sources previously identified in Australia

Hay enterprise underpins crop expansion
Issue 153, July-August 2021 - 2021-06-22T09:00:00+10:00A sophisticated export hay enterprise has provided a profitable, low-risk foundation for a South Australian family’s cropping expansion at Lameroo in the southern Mallee region. Grower, agronomist and GRDC southern region panelist Lou Flohr says the total farm area, including owned and leased land, has more than doubled from 2000 to 4500 hectares in the past five years.

Disease tool to inform growers’ variety choices
Issue 153, July-August 2021 - 2021-06-16T09:00:00+10:00A project is developing a ‘yield loss to disease’ tool that draws on five years of Australian field trial data and statistical analysis. The tool will be used to determine likely yield responses to various disease loads for wheat varieties with different resistance and tolerance ratings.
