Bedstraw Eradication Program 2021/22: Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Agriculture reports

Three-horned bedstraw is a competitive weed that can cause considerable yield loss in crops, and its seeds contaminate fodder and grain. To stop the weed becoming established in Western Australia and impacting production, WA grain/seed/hay growers (via the Grains, Seeds and Hay Industry Funding Scheme) fund the Bedstraw Eradication Program.

Grains Research And Development Science Highlights 2015-17, Department Of Agriculture And Food Western Australia

All other publications

Western Australian grain production and industry value has quadrupled over the past 30 years, despite declining winter rainfall, more frost and high temperature events, acidifying soils and increasing input costs. Strong evidence links this productivity growth to R&D that has delivered genetically superior varieties, better agronomic practices and more reliable farming systems. Western Australian grain growers are innovators that rapidly adopt new technology which is increasingly sourced from a wider pool of national and global science, research and innovation. Continuing to push the productivity frontier is not only critical to grower’s profitability, it underpins the international competitiveness of our exports …

Genetically Modified Canola Trials In 2009, Department Of Agriculture And Food, Western Australia

Research Reports

During 2009, just over 860 hectares of Roundup Ready® canola were grown in Western Australia enabled by an exemption order under the Genetically Modified Crops Free Areas Act 2003. The aim of the trials was to establish whether GM canola could be segregated from non-GM canola along the WA supply chain, and whether GM canola was agronomically viable for WA farming systems. This was the first time genetically modified canola had been grown on a commercial scale in WA - earlier exemptions for smaller trials had been for variety testing and scientific purposes.

Field Pea In The Great Southern, Ian Pritchard, Rodger Beermier, Mark Seymour

All other publications

Semi-leafless field pea like Kaspa have lifted the benchmark set by the previous conventional varieties such as Parafield and Dunwa. Semi-leafless field pea have the same traits as conventional field pea: adaptation to a range of soil types; wide selection of weed control options (including crop topping); nitrogen input; disease break; and reduction in root lesion nematodes. Semi-leafless pea is easier to harvest and is less prone to pod shatter.

Phosphorus And Nitrate Loss From Horticulture On The Swan Coastal Plain, Neil Clifton Lantzke

Agriculture reports

(En) The extent of nutrient loss from nine horticultural properties located on the sandy soils of the Swan Coastal Plain was examined. On three of the properties phosphorus (P) loss was measured by monitoring nutrient loads in shallow drains. On the other six properties networks of monitoring bores were installed and both P and nitrate nitrogen (NO3-N) concentrations were monitored. All of the properties except one were located on the low phosphate fixing Bassendean sands. The level of nutrient loss was depend l production areas. High to very high N03-N concentrations were found in the shallow groundwater beneath the production …

Analysis Of Black Point In Wheat, J M. Wilson

Technical Bulletins

Fungal staining (black point) of wheat can reduce the quality of grain. The most serious problem is a discolouration of products. Discolouration is a consequence of infection by microorganisms. The most likely cause in Western Australia is a species of the common fungus Alternaria. Infection and discolouration occur between flowering and grain maturity, and the optimum environmental conditions are probably consecutive days of high relative humidity together with warm temperatures.

Visions For Agriculture, Department Of Agriculture, Western Australia

Agriculture reports

This workshop grew out of a conversation between Maurice Barnes, a Trayning farmer and member of the Research Advisory Committee of the Dryland Research Institute, and Steve Porritt, the officer in charge of the Dryland Research Institute at Merredin. Maurice was interested in the idea of posing the question 'What would agriculture be like if we had known as much about this landscape in 1829 as we know now?', to a group of farmers and others interested in the central wheatbelt and its future. Maurice saw this question as a first step toward achieving some shared vision for the future …

Quest For Quality Operation Quality Wheat, Sue Bestow

Agriculture reports

Variations in the protein content of wheat are largely associated with growing conditions, particularly rainfall and soil type, which influence nitrogen supply and crop yield. Management to improve protein generally also improves yield, so in future both must be considered when comparing profitabilities of management options, particularly if payment for protein increases.
