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.


  • 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 plant and

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

  • The Crop Sowing Guide for Western Australia aims to provide information to support growers with decisions on the best choice of variety for each of the major crops for the upcoming season.

  • The aim of carbon farming is to sequester more carbon and reduce greenhouse gas emissions, as part of Australia's response to climate change.

  • This page contains information on the optimum sowing windows to maximise grain yield of canola, for 24 locations, three soil types and three canola cultivars, obtained from the APSIM-Canola model a

  • If you have bare paddocks or patches, you may be considering reseeding your canola.

  • The oat industry delivers nearly $200 million to the state economy each year through oats for human consumption and feed.

  • The aim of having minimum standards of maturity is to ensure consumer satisfaction and encourage repeat sales.

  • Unloading grain into a chaserbin

    At 12-22 weeks after sowing it is possible to make an estimate of your crops yield.

  • Before committing resources to late sown or emerging crops, carefully consider its yield potential and risks to achieving that yield. If the expected yield is greater than the variable cost breakev
