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 Australian agriculture experiences variability in its winter growing season (May–October): late starts, early finishes and 'dry seasons' with rainfall low enough to cause serious crop stres

  • The field establishment of grain crops is the percentage of the sown seed that goes on to produce established plants. At sowing, management and environment are the key issues.

  • There are many aspects to consider when seeding grain crops at the break of the season.

  • Climate change is putting pressure on wheat yields in south-west Western Australia (WA) in several ways: lower annual and autumn and spring rainfall; later starts to the growing season; higher temp

  • The potential yield tool uses seasonal rainfall and decile finishes, calculated from historical data, to calculate the maximum wheat yield possible in the absence of any other constraints.

  • Plant available soil water graphs show the amount of soil water accumulated from the start of summer (1 November) through the grain growing season and can be used as a tool in the seasonal decision

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