Stubble Retention And Leaf Disease In Lupin And Cereal Crops, Mark Sweetingham, Robert Loughman, Ron Jarvis Jan 1992

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


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.


Wider Spaced Rows For Lupins, Ron Jarvis Jan 1992

Wider Spaced Rows For Lupins, Ron Jarvis

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

In this farm scale trial at Wongan Hills, a lined combine was used to seed lupins into rows spaced 380 mm apart in wheat stubble.


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


Stubble Retention For Control Of Wind Erosion, Dan Carter, Paul Findlater, Steve Porritt Jan 1992

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.


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 …


On The Trail Of The Native Budworm, Kevin Walden Jan 1992

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 …


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.


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.

Revegetation Guide To The Central Wheatbelt, E C. Lefroy, R J. Hobbs, L J. Atkins, Department Of Agriculture And Food, Western Australia, Csiro, Division Of Wildlife And Ecology Sep 1991

Revegetation Guide To The Central Wheatbelt, E C. Lefroy, R J. Hobbs, L J. Atkins, Department Of Agriculture And Food, Western Australia, Csiro, Division Of Wildlife And Ecology

Bulletins 4000 -

The rapid development of the central wheatbelt for agriculture over the past century has produced a productive farming landscape, but one which is increasingly subject to degradation. Erosion, salinization, declining soil structure, waterlogging and acidification are all symptoms of this degradation and causes of lost agricultural production. In addition, most of the native vegetation and many of the native animals have disappeared, and the natural heritage of the area resides in small scattered patches that together make up only seven per cent of the wheatbelt region.

Many farmers now recognize that replanting trees and shrubs is an effective means of …

Propagation Of Yellow Bells (Geleznowia Verrucosa Turcz., Rutaceae) From Seed, Blakely Paynter, Kingsley Dixon Aug 1991

Propagation Of Yellow Bells (Geleznowia Verrucosa Turcz., Rutaceae) From Seed, Blakely Paynter, Kingsley Dixon

Grain and Other Field Crops Research Articles

Geleznowia verrucosa Turcz. (Rutaceae) is a commercially important, bush-picked wildflower that has no known commercial means of propagation. This study examined factors influencing seed dormancy and likely to restrict germination of the species. Germination of entire, untreated seed was low (less than 2%), but removal of a small portion of the testa at or near the radicle end of the seed improved germination. This response was affected by the temperature under which the seed germinated, but was unaffected by exposure of the seed to light while germinating. The percentage germination of nicked seeds 52 days after sowing increased from 8% …

Pasture Condition Guides For The Murchison River Catchment, A Fox, T R. Eckersley Jan 1991

Pasture Condition Guides For The Murchison River Catchment, A Fox, T R. Eckersley

Soil conservation survey collection

Knowledge of the pasture resource and its capabilities is essential to sustainable use of the rangelands. Rangeland managers must be able to recognise firstly the different pasture types, and secondly, the differences between present condition classes for each type. Both factors affect the stock carrying capacity, and appropriate pastoral management of a pasture. This guide has been produced for use by pastoralists to assist them to recognise and assess the condition of the perennial pasture resource of their own properties. The guide describes the condition states found in 10 of the most widespread pastures of the Murchison River catchment (Fig. …
