Wheat

Wheat production accounts for 70% of total cereal production in Western Australia with about seven million tonnes generated annually in a rain-fed system across four million hectares of land.

About 80% of WA wheat is exported - predominantly to Asia and the Middle East - generating $2 billion in annual export earnings for the state.

Yields of WA-bred premium wheat varieties have risen by 1% per year during the past 30 years, a rate higher than world average.

The Department of Primary Industries and Regional Development has a strong research, development and extension focus on wheat production through its long history in wheat breeding (now privatised through Intergrain) and the development of wheat variety management packages for the state’s grain production zones.

  • Western Australia has seen major changes to the agronomic system, including a drying climate, more intensive cropping rotations and the widespread adoption of no-till.

  • Management of weeds, disease and nitrogen nutrition are ongoing challenges that limit yield potential.

  • This trial examines the positive impact of crop competition, crop type rotation and the mouldboard plough on weed management.

  • Wild radish (Raphanus raphanistrum) is highly competitive in crops and can cause a yield loss of 10-90%.

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

  • 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%.

  • In an integrated weed management program, control of weeds should occur in the fallow, pre-sowing, early post-emergent and in pasture phases.
