Grains Research & Development

The Department of Primary Industries and Regional Development has grains research and development connections across Australia and with more than 25 countries worldwide – ranging from collaboration with Japanese flour millers involved with the udon noodle industry through to seeking out barley genes tolerant of acid soils on the Tibetan Plateau and commercialising department-bred lupin varieties for use in the Chilean salmon industry.

These research, development and extension linkages and partnerships underpin the department’s capacity to tackle grains issues of national and regional agricultural importance and deliver profitable management solutions to the state’s 4000 grain producers.

The department is committed to leading and contributing to specific priority areas of research and development through the Grains Industry National Research, Development and Extension (RD&E) Strategy.

The Grains Research and Development Corporation (GRDC) – a national organisation coordinating research and development of behalf of Australian grain growers is a key funder of the department's grain research, development and extension activities.

Major initiatives being undertaken through the GRDC-DPIRD partnership include developing solutions to frost and soil constraints, which together can cost the Western Australian grains industry hundreds of millions of dollars in lost production each year.

  • In 2023, the Department of Primary Industries and Regional Development (DPIRD) is conducting more than 250 research trials across the state.

  • The term 'residual' applies to a number of herbicides that have a long lasting activity in the soil. These herbicides are often applied directly to the soil prior to planting crops, pre-emergent.

  • One-off soil inversion results in the complete burial of the water repellent topsoil in a layer typically at a depth of 15 to 35 cm, and brings to the surface a layer of wettable subsoil.

  • Windmill grass (Chloris truncata) is a native species and is the tenth most common summer weed species in the Western Australian wheatbelt.

  • Annual ryegrass (Lolium rigidum) is one of the most serious and costly weeds of annual winter cropping systems in southern Australia.

  • Brome grasses (Bromus spp.) are highly competitive weeds, most problematic in wheat crops.

  • The Weed Seed Wizard is a computer simulation tool that uses paddock management information to predict weed emergence and crop losses.

  • ‘Risk-aware’ growers can implement strategies to reduce and avoid unnecessary introduction and spread of weeds.

  • The most accurate way to estimate the weed population of a paddock is to count the number of plants in an area of known size at a number of locations.

  • In Western Australia, competition from 7-90 capeweed plants per square metre in a wheat crop can reduce crop yield by 28-44% and net return by 25-76%.
