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 …

No-Tillage Seeders And Their Adoption In North America With Relevance To Western Australia, J K. Bligh
No-Tillage Seeders And Their Adoption In North America With Relevance To Western Australia, J K. Bligh
Resource management technical reports
The adoption of no-tillage seeders appears generally to be at a similar stage in North America as in Western Australia. One notable difference is the communication provided by several no-tillage farmers organisations, such as the Manitoba-North Dakota Zero Tillage Farmers Association. Since almost all development of no-tillage systems has been carried out by farmers, such associations have proven invaluable in directly providing communication with their peers.

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.

Stubble Retention For Control Of Wind Erosion, Dan Carter, Paul Findlater, Steve Porritt
Journal of the Department of Agriculture, Western Australia, Series 4
The surest way to control wind erosion in continuous cropping systems is to retain stubble. Over the past ten years, Western Australian research has focused on the amounts of stubble needed to prevent that erosion.

Domestication Of Rough-Seeded Lupins, Bevan Buirchell, Wallace Cowling
Journal of the Department of Agriculture, Western Australia, Series 4
Since the beginning of civilisation, humans have been domesticating wild plants such as wheat, barley and rice. They have both conciously and unconciously selected plant types suited to cropping.
Reccently, there has been an increasing effort to domesticate a greater variety of wild plants, especially legumes.
The Role Of Earthworms In Western Australian Agriculture, Tom Mccredie, Lex Parker
The Role Of Earthworms In Western Australian Agriculture, Tom Mccredie, Lex Parker
Journal of the Department of Agriculture, Western Australia, Series 4
Earthworms have a reputation as soil builders and renovators, particularly among 'organic' farmers and gardeners. They improve soil fertility through increased aeration, aggregation, water infiltration and release of nutrients from organic matter. However, the benefits of earthworms in the wheatbelt have been doubted for many years because of their poor survival in cultivated soils.
Since cropping began in the Western Auslmlian whealbelt over 1OO years ago, the physical condition of many soils has deteriorated. The primary causes of soil degradation were the European cultivation practices used by farmers and the trampling effect of introduced animals. in particular, sheep.

Stubble Handling Machinery, Greg Haydon
Stubble Handling Machinery, Greg Haydon
Journal of the Department of Agriculture, Western Australia, Series 4
Farming in Western Australia, and in Australia, has undergone a revolution over the past 15 to 20 years. Two significant changes have been the cessation of ploughing to kill weeds, that is, the change from discs to tines, and the reduction in tillage through the use of agricultural chemicals. These have been important changes that have had conservation benefits. However, to handle stubble to best effect, further changes in machinery, newer machinery and combinations of machines will be needed. In this article, the author discusses current and possible future practces.

Few farmers in Western Australia today would question the desirability of retaining crop stubble. The problem usually is how to manage stubble so that it does not interfere with other parts of the farming system

Few farmers would question the desirability of retaining stubbles, both for control of erosion by wind and water, and to return organic matter to the soil. While the present debate is focused on the short term management of stubbles, longer term effects also need to be considered.
The Department of Agriculture has several long-running trials intended to measure long term effects.

Retention of cereal stubbles can reduce leaf disease in lupins but increase leaf disease in cereals. The extent of cereal disease carry-over in stubbles depends on the locality and whether multiple cropping or crop rotation is practised

Opportunity Knocks : Sowing Wheat Early In The North-Eastern Wheatbelt, Nicole Kerr, Doug Abrecht
Journal of the Department of Agriculture, Western Australia, Series 4
Farmers consider many factors in deciding whether to start sowing wheat, but the most important are the amount of rain and time of year. In this study we assessed the chances of farmers in the north-eastern wheatbelt (less than 325 mm rainfall) receiving enough rain to sow wheat early. In low rainfall areas such as this, where an early finish to the season is likely, it is especially important that farmers take advantage of all early sowing opportunities. The potential benefits of sowing wheat early generally outweigh the associated risks, particularly in lower rainfall areas. However, early sowing depends on …
Wheat Quality And Wheat Variety Decisions, Mark Stevens
Wheat Quality And Wheat Variety Decisions, Mark Stevens
Journal of the Department of Agriculture, Western Australia, Series 4
The choice between which wheat variety to plant has always been a trade-off between yield and wheat quality. When wheat prices were higher and quality payments were less, quality considerations were of little importance and varieties were selected almost entirely on yield potential. Now, with low wheat prices and a greater emphasis on wheat quality from our customers, growers must place more importance on quality characteristics when selecting varieties. For example, should a grower select a higher yielding average quality wheat such as Spear, or a lower yielding, good quality wheat such as Machete? The important question a wheat grower …

Test Detects Resistant Green Peach Aphids In Lupins, Francoise Berlandier, Ian Dadour
Journal of the Department of Agriculture, Western Australia, Series 4
Confirmation of insecticide resistance in green peach aphid in Western Australia's lupin crops means farmers will have to choose insecticides much more carefully to control this pest. Resistance within an aphid population varies, and when resistant aphids are no longer exposed to insecticides, they may revert back to being susceptible in as little as one generation. Furthermore, when these revertant populations are exposed to the same insecticides in the future, resistance quickly reoccurs. In this article, the authors discuss a test to determine the extent of insecticide resistance in green peach aphid and how to manage it.

Managing Brome Grass In The Wheat:Lupin Rotation, Aik Hock Cheam, Gurget Gil, Christine Zaicou
Journal of the Department of Agriculture, Western Australia, Series 4
Some farmers and scientists are questioning the sustainability of the cereal:lupin rotation in the Western Australian wheatbelt.
Being a 'tight' rotation, its continuation is constantly under threat by disease, especially lupin root rots caused by Pleiochaeta (the brown spot organism) and Rhizoctonia fungi. To control disease, some farmers have lengthened the rotation to three years, such as wheat:wheat:lupins or wheat:barley:lupins. The longer cereal phase also helps to stabilise soil against wind erosion. However, such rotations can lead to a rapid buildup of brome grass during the two consecutive years of cereals. The implications of these rotations on the severity of …
On The Trail Of The Native Budworm, Kevin Walden
On The Trail Of The Native Budworm, Kevin Walden
Journal of the Department of Agriculture, Western Australia, Series 4
Native budworm, the worst pest of lupins, is a bit of a uiill-o-the-unsp. Some years the native budworm moths go virtually unnoticed. In others, they appear in plague proportions without warning - in these years, the cost to growers in lost yield runs into millions of dollars.
If an early warning system can be developed to predict the extent of moth flights into lupin crops, and this seems possible, major crop losses could be averted.
The Department of Agriculture has started research to develop a system of predicting the size of spring flights of native budworm moth. We need to …
