Santiago Extends The Range Of Burr Medics, Clinton K. Revell, Michael Ewing

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

The release of Santiago follows an extensive Department of Agriculture testing programme conducted primarily in the 325 to 425 mm rainfall zone. Santiago substantially outperformed both Serena and Circle Valley and was the best amongst the large number of non-commercial medic varieties tested. About 500J000 ha were sown to burr medic between 1983 and 1988 and the Department of Agriculture expects that the release of Santiago will result in additional new plantings from

New Initiatives In Processing Australian Sheep Skins, P G. Frapple

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

Australia's exports of 313 million preserved sheep and lamb skins were valued at $A261.2 million FOB (free on board) in 1986-87. Just over 40 per cent (13.1 million) of these skins went to France for fellmongering, which is the process of removing wool from skins, leaving a bare pelt suitable for tanning. The balance went to other countries including Yugoslavia, Spain and West Germany, mainly for tanning with the wool on.

New Wool Prices Beg Higher Stocking Rates, K M S Curtis

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

In the past few years, increases in wool prices have varied, depending on fibre diameters. In 1987-88, fine wools (19 micron) were selling for as much as twice the price paid for coarse wools (26-27 micron). A wool producer can alter the fibre diameter of the wool produced through breeding and by management. This article discusses the effect of changing stocking rate on wool production, using WOOLMODEL to do the calculations (Curtis, 1986,1988). WOOLMODEL can also be used to examine the effect of changes in phosphorus application rates.

Improving Lupin Pod Setting And Yield, R J. Delane

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

Western Australia's lupin production has grown twenty-fold since 1977. Lupins are now a valuable seed, feed and rotation crop on light-textured neutral and acid soils throughout southern Australia. Nevertheless, both experimental and commercial yields have been variable over sites and seasons. A major cause has been excessive flower and pod abortion on the main stem. Farmers have often commented on well grown lupin crops which appear to carry few pods

Diseases Of Native Flowers, Peter Mcr Wood

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

The native flora of Australia has evolved in such a way as to render it resistant to many of the fungi and bacteria that commonly infect exotic cultivated flower crops. Many of our native plants have tough sclerophyllous foliage which makes it difficult for pathogenic organisms to gain access, particularly in their natural undisturbed habitats. Root tissue of these plants also tends to be woodier than that of exotic plants, thus making it less accessible as a food source for common rootattacking fungi such as Rhizoctonia and Pythium.

Post-Harvest Research On Ornamental Plant Material, Daryl C. Joyce

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

The rapid growth of commercial enterprises servicing overseas demand for native cut flowers and foliage from Western Australia has created a need for research and extension to support the industry. Post-harvest handling is a particularly important area because cut flowers and foliage are highly perishable and Western Australia is a long way from major markets. Markets such as The Netherlands, Japan and California demand high quality products

Btec Campaign Ends In 1992, Carole A. O'Dwyer

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

BTEC, the national brucellosis and tuberculosis eradication campaign, is funded jointly by cattle producers and the Commonwealth and State Governments. When the campaign was launched on July 1,1970, its aims were to remove a potential export trade barrier and to improve the level of herd health. The campaign should be substantially completed by the end of 1992.

The Kimberley region of Western Australia was declared free of brucellosis in April 1980, and the entire State was declared free in 1985, the first mainland State to achieve this status.

All parts of Western Australia south of the 20th parallel were declared …

Cereal Straw And Stubble For Sheep Feed, E M. Aitchison

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

Many farmers in Western Australia run sheep in addition to their cropping programmes. The resulting cereal straws and stubbles are therefore important as sheep feed during summer and autumn. During this period the diet must provide sufficient energy to maintain liveweight, but additional energy and protein may be required for young stock and pregnant or lactating ewes, and to reduce problems from tender wool.

Rehabilitation Of Mined Areas And Control Of Dust At Kalgoorlie And Boulder, A E. Peterson

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

One of the lesser known roles of the Department of Agriculture is advising on aspects of managing and rehabilitating non-agricultural land. This advice and research is directed mainly at minimizing the effects of land degradation and providing land resource data and land capability assessment maps to assist regional planners.

Grazing The Rangeland : Towards An Understanding, Alec Mcr Holm, Donald Burnside

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

Western Australia's rangelands are those parts of the State, excluding deserts, where inadequate rainfall prohibits their development for a cultivated agriculture. About 980,000 sq. km of these rangelands are held as pastoral leasehold land, with a total of 450 individual station businesses. These native pasture lands support about 2.5 million sheep and 850,000 cattle. The rangelands can be divided into three main natural regions, each of which has a distinct climate and vegetation. These are the Kimberley region; the north-western spinifex region, which includes the Pilbara; and the Acacia shrubland region of the Gascoyne, Murchison, Goldfields and Nullarbor areas. This …

An Evaluation Of Cattle Types For The East Kimberley, David Pratchett, Mick Carrick, Stuart Young

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

The first cattle to be introduced to Western Australia's Kimberley region arrived at Ord River Station in 1884, after Nathaniel Buchanan had walked 4000 head of Shorthorn cattle overland from Queensland, on behalf of the owners, Osmond and Panton.

In the early years of the Kimberley pastoral industry the virgin pastures allowed stock numbers to increase rapidly. Little consideration was given to stock or rangeland management, or to whezther other types of cattle could be raised for improved production.

The Department of Agriculture started a comprehensive trail at Ord Regeneration Research Station (previously Ord River Station) in 1980 to evaluate …

The Western Australian Sheep Skin Industry, P G. Frapple

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

Sheep skins are a by-product of livestock production and slaughter. Their supply is determined largely by the demand for meat, rather than the demand for leather and leather products. As a result, skin prices fluctuate widely, as happened from April to June, 1988.

1080 Does Not Threaten The Northern Quoll, D R. King

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

The poison 1080 is used in baits to control animal pests such as dingoes, rabbits and, indirectly, foxes. There is always the risk that some "non target" animals, particularly our native animals, might eat the baits and die, although investigations indicate that many southern native mammals are tolerant of 1080. The compound 1080 is found in many native plants growing in southern Western Australia, in the genera Gastrolobium and Oxylobium, and over the centuries native animals have built up resistance to its effects. Until recently the tolerances to 1080 of only a few animals from the pastoral areas were known. …

Control Of Caprine Arthritis-Encephalitis In Goats, T M. Ellis

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

Caprine arthritis-encephalitis, CAE for short, is the name given to a disease complex in goats, one form of which, 'big knee', has been recognized in dairy goats in Australia since the late 1950s. There are many forms of this progressive disease, all of which result in premature culling in milking goats

Fox Attacks On Cashmere Goats, John L. Long, Peter Mawson, Peter Hubach, Neville Kok

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

Since the fox arrived in Western Australia from South Australia in the early 1900s it has preyed on our native animals and domestic livestock, traditionally lambs and poultry. With the establishment of a Cashmere goat industry in the State, the potential exists for the fox to become an even greater problem.

Pests Of Native Flowers, W M. Woods

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

For millions of years native insects have used Australia's native plants for food and shelter. Today, we wish to cultivate these plants to produce beautiful flowers and foliage for export. However, the insects that live on the plants in the wild will attack those plants grown in cultivation, and these insects themselves will be attacked by their own predators and parasites. The challenge in floricultural entomology is to use this natural biological control as part of a cheap and effective pest management system.

Murex Medic : A New Pasture Species, Dennis J. Gillespie

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

Murex medic (Medicago murex) is a new species of medic not previously used commercially anywhere in the world. The first variety, Zodiac, was developed by the Western Australian Department of Agriculture and released to seed producers throughout Australia in 1988. Other varieties are being evaluated and further releases are likely in a few years.
