Canola

Western Australia is the major canola growing state in Australia producing about 40% of the nation’s 2.7 million tonnes each year.

The majority of WA canola is exported – generating about $0.6 billion for the state’s economy each year, with the Netherlands, Belgium, Germany and Japan WA’s largest export canola markets.

WA canola is renowned for its high oil content – with the state consistently achieving higher oil contents than the rest of the nation.

The Department of Primary Industries and Regional Development supports the WA canola industry through agronomic research and development; and pest and disease identification and management.

    Nitrogen deficiency is the most common nutrient deficiency in canola especially during cold, wet conditions and in sandy soils in high rainfall areas.

    Diagnosing boron deficiency in canola

    8 May 2014

    Boron deficiency is rare in most crops sown in Western Australia. However boron deficiency is likely to impact broadleaf crops such as lupin and canola before cereals.

     

  • Younger leaves develop interveinal paleness/yellowing, but veins remain green

    Diagnosing manganese deficiency in canola

    8 May 2014

    Canola is less susceptible to manganese deficiency than cereals but it has been seen more in recently heavily limed soils.

  • Pale plants with scorched leaf margins and interveinal chlorosis

    Diagnosing molybdenum deficiency in canola

    8 May 2014

    Many sandplain soils and gravelly sands in WA were molybdenum deficient in their natural state.

  • Deficiency most commonly shows as smaller plants with similar shaped leaves

    Diagnosing phosphorus deficiency in canola

    8 May 2014

    Nearly all soils in WA were phosphorus deficient but continual use of phosphorus fertiliser means acute deficiency in broadacre crops is rare, with the exception of Darling Range gravels.

  • Serrated leaf blades that extend further down the petiole become thickened and roll inwards showing purple undersides

    Diagnosing sulphur deficiency in canola

    8 May 2014

    Canola frequently shows early sulphur deficiency symptoms, but yield is often unaffected because plants access available sulphur reserves in the subsoil.

  • Stunted plants with pale younger leaves

    Diagnosing zinc deficiency in canola

    8 May 2014

    Although canola is moderately susceptible to zinc deficiency, it is rarely seen in the paddock because many fertilisers have trace zinc levels, canola appears to be more effective in using soil zin
