Visions For Agriculture, Department Of Agriculture, Western Australia Oct 1992

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 …

Distribution And Ecological Significance Of On-Farm Bushland Remnants In The Southern Wheatbelt Region Of Western Australia, F Mollemans, G Beeston Jul 1992

Distribution And Ecological Significance Of On-Farm Bushland Remnants In The Southern Wheatbelt Region Of Western Australia, F Mollemans, G Beeston

Soil conservation survey collection

The Southern Wheatbelt Region Remnant Vegetation Survey was funded by the Save the Bush program, and aimed at surveying pieces of on-farm remnant vegetation in the "Great Southern" of Western Australia. At the outset a total of 13 shires were selected for survey, namely: Broomehill, Corrigin, Dumbleyung, Katanning, Kent, Kondinin, Kulin, Lake Grace, Narrogin, Tambellup, Wagin, Wickepin, Woodanilling. However, time constraints (available funding indicated a time frame of 40 weeks for the project to be completed) meant that subsequently Kent and Lake Grace shires (two of the largest) had to be dropped from the survey to allow for proper completion …

No-Tillage Seeders And Their Adoption In North America With Relevance To Western Australia, J K. Bligh Apr 1992

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.

Quest For Quality Operation Quality Wheat, Sue Bestow Mar 1992

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.

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 Jan 1992

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 Jan 1992

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.

The Pros & Cons Of Retaining Stubble, Department Of Agriculture And Food, Western Australia Jan 1992

The Pros & Cons Of Retaining Stubble, Department Of Agriculture And Food, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

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


Results Of Stubble Research In Western Australia, Michael Perry, Ron Jarvis, Mel Mason, David Tennant Jan 1992

Results Of Stubble Research In Western Australia, Michael Perry, Ron Jarvis, Mel Mason, David Tennant

Journal of the Department of Agriculture, Western Australia, Series 4

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.


The Impact Of Red Kangaroos On The Rangelands, Grant Norbury, Dale Norbury Jan 1992

The Impact Of Red Kangaroos On The Rangelands, Grant Norbury, Dale Norbury

Journal of the Department of Agriculture, Western Australia, Series 4

Kangaroos and other native animals should be maintained across their natural range, including areas set aside for pastoral use. But the added grazing pressure on native vegetation from sheep, cattle and feral animals, together with unnaturally high numbers of kangaroos, has seriously degraded much of our rangelands. Cattle and sheep numbers are relatively easy to control. The same cannot be said for kangaroos. Access to widespread man-made watering points has allowed kangaroos to continue breeding when normally a shortage of water would suppress reproduction.

Pastoralists complain that commercial kangaroo shooting is not always effective in preventing damage caused by kangaroos. …

Stubble Retention And Leaf Disease In Lupin And Cereal Crops, Mark Sweetingham, Robert Loughman, Ron Jarvis

Journal of the Department of Agriculture, Western Australia, Series 4

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


Wheat Quality And Wheat Variety Decisions, Mark Stevens Jan 1992

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 Jan 1992

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.
