WAN00021 - Dry Seeding in Western Australia
Project WAN00020 highlighted that dry seeding in Western Australia can increase productivity, predominately, in low to medium rainfall years but also increases risks with weed control, frost and heat stress. Three key research and extension priorities were identified that will benefit growers that adopt the practice of dry seeding in terms of risk management and productivity gains:1. Setting up the paddock: Management of soil water availability through fallow management, rainfall through autumn and summer and weed control. Weed seed bank management through long term integrated weed management strategies and herbicide efficacy pre seeding.2. Survival and Establishment of dry seeded crops: Crop seed viability and longevity in marginal soil moisture, early seedling survival under prolonged water deficits.3. Late season Risks: Agronomy of dry seeding to avoid heat stress, frosts and to maximise water use efficiency. Guidelines will be developed around these areas through field applied research and modeling outputs.
