Production & postharvest

The Department of Primary Industries and Regional Development contributes to the productivity, profitability and sustainability of plant-based agriculture. From broad scale dryland cropping systems to intensive irrigated production, we work with industry and business to address challenges in plant production through research and development, knowledge transfer and government policy settings.

    3 February 2015

    Manganese toxicity is rare in WA, but may occur on acidic heavy soils with high manganese levels.

    Diagnosing nodule dysfunction in narrow-leafed lupins

    19 January 2015

    Nitrogen deficiency from nodule dysfunction can be caused by lack of Rhizobia, soil conditions, herbicide toxicity, or molybdenum or cobalt deficiency.

    Diagnosing poor quality seed in narrow-leafed lupins

    19 January 2015

    Lupin has large seeds that are prone to mechanical damage during harvesting and subsequent handling, which may reduce seed viability.

  • Seedlings have deformed roots and shoots.

    Diagnosing allelopathy in cereals

    28 November 2013

    Allelopathy is an uncommon disorder of germinating plants caused by a toxins in the soil that have leached from plant residues.

    Monitoring pulse nodulation

    15 April 2014

    All pulse plants require healthy root systems in order to maximise growth and yield.

  • Smaller less developed tillers on the left

    Monitoring cereal tiller counts

    15 April 2014

    The ability of a cereal crop to tiller is an indication of the crop’s ability to maximise crop yield. An inadequate number of tillers will limit the number of heads and yield potential.

  • Flowering canola paddock

    Monitoring flowering in broad-acre crops

    15 April 2014

    The time of flowering can be critical in determining final yield in all crops. Frost or hot, dry conditions during flowering in cereal, canola and pulse crops can dramatically reduce yields.

    Windrow assessment for canola

    15 April 2014

    The aim of this check is to ensure that the crop is at the right stage of maturity for windrowing. This will ensure that seed yield and oil content are maximised.

  • Flowering kaspa crop

    Monitoring head and pod density

    15 April 2014

    The number of tiller in cereals establishes the yield potential of the crop for the season. The branching of legumes and canola largely determines the yield potential in these crops.

    Crop productivity on raised beds in Western Australia

    18 February 2011

    The costs of installing a system of raised beds should be recovered through a cropping program.
