Crops

The Department of Primary Industries and Regional Development continues to support the growth and international competitiveness of all crop industries in Western Australia.

With a 2400 kilometre span from its tropical north to its temperate south, WA supports a broad range of cropping industries from rain-fed winter cereals through to irrigated horticultural crops.

In the 2012/13 year the WA cropping industries exported a total of $3.9 billion which comprised: $3.1 billion of cereals, $859 million of pulses, pastures and oilseeds, $142 million of horticultural crops. The major contributors to these exports were wheat ($2.7 billion), canola ($756 million), barley ($377 million), lupins ($42 million), carrots at $48 million, oats ($12 million), and strawberries at $5.5 million.

    All winter grains susceptible to frost. Wheat is more susceptible then barley at flowering, but it is not known if barley and wheat have different frost susceptibilities during grain fill.

  • Department of Primary Industries and Regional Development (DPIRD) Research Officer Ben Biddulph was interviewed by reporter Debra Bishop for a Grains Research and Development Corporation (GRDC) Gro

  • Wheat is highly susceptible to frost damage between ear emergence and flowering – often termed reproductive frost.

  • In September 2017, six department research officers presented at the biennial Australian Agronomy Conference in Ballarat, Victoria.

  • Mottled pods

    Of the pulses, field peas are more vulerable to frost due to thin pod walls and exposure of flowers to frost. 

  • Young pods abort or are poorly filled

    Canola is most susceptible to frost damage from flowering to the clear watery stage (approximately 60% moisture). Plants frequently recover from frost at early flowering by producing more flowers.

  • Growing oaten hay on frost-prone paddocks minimises the frost risk as it is cut soon after flowering, avoiding the frost-sensitive period.

  • Through targeted grains research and development (R&D), the Department of Primary Industries and Regional Development's (DPIRD) Boosting Grains Research and Development project aims to increase

  • Plants affected at flowering develop wilted upper foliage

    Narrow-leafed lupins tolerate frost in early growth stages but are susceptible when growing rapidly from flowering to early pod fill.

  • The cool Mediterranean conditions of the South-West of Western Australia are sub-optimal for avocado production which can impact on the reliability of cropping.
