Introduction Of The Red-Browed Finch To Western Australia, John L. Long Jan 1969

Introduction Of The Red-Browed Finch To Western Australia, John L. Long

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

THE Red-browed Finch (Estrilda temporalis) has been established probably since 1958 in orchard clearings in Darling Range gullies east of Perth.

Although some concern has been shown at the introduction of a new species to Western Australia, it appears to be of little economic importance.


Pig Husbandry Research In Western Australia, N W. Godfrey Jan 1969

Pig Husbandry Research In Western Australia, N W. Godfrey

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

IN the past it has not been possible to undertake research work with pigs on any appreciable scale in Western Australia.

A small herd has been maintained at Denmark Research Station for some years as a demonstration side-line unit, run in conjunction with the dairy herd.

A number of very useful trials have been carried out with the Denmark herd, but its size has limited the comprehensiveness of the type of research work that could be undertaken.

Wildflowers Of The Geraldton District, E M. Bennett Jan 1969

Wildflowers Of The Geraldton District, E M. Bennett

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

THE wildflowers of Western Australia which have aroused such interest throughout the world are found largely in the south western corner of the State.

Within this area, and indeed in the drier areas also, certain districts are richer than others.

One example of this concentration of wildflowers occurs to the north and east of Geraldton.


Shed Lambing In The Esperance Environment, T Marshall, F. F. Dixon Jan 1969

Shed Lambing In The Esperance Environment, T Marshall, F. F. Dixon

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

Neonatal lamb mortality is often high in Western Australia and losses as high as 33 per cent, have been recorded on private properties in the Esperance area. Surveys by Western Australian Department of Agriculture officers have indicated that more than threequarters of such lamb deaths occur after birth. About half these deaths result from the combined effects of weather and mismothering.

Work in Victoria has indicated that lamb mortality may be reduced by intensive lambing systems such as shedding and this trial was established to see if shedding could reduce lamb mortality in the Esperance environment.

Are Bactericides Necessary In Sheep Dips?, M R. Gardiner

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

THE OCCURRANCE of mycotic dermatitis in sheep in Western Australia, although rather unpredictable, is quite frequent throughout the higher rainfall districts.

Efforts have been made for several years to control infection by adding bactericides to dips.


The Use Of Pickled Wheat In Poultry Feeding, P Smetana Jan 1969

The Use Of Pickled Wheat In Poultry Feeding, P Smetana

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

FEEDING fungicides to poultry can result in harmful effects, to the birds themselves, and to their human consumers.

To prevent such effects it is advisable that wheat pickled with fungicides should not be included in poultry rations.


Superphosphate For Wheatbelt Pastures : Rates Of Application, Walter Jacob Cox Jan 1969

Superphosphate For Wheatbelt Pastures : Rates Of Application, Walter Jacob Cox

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

BECAUSE Western Australian soils are low in phosphorus, frequent applications of superphosphate are required for both crop and pasture production. The recommended rates are determined from the results of field experiments that test different quantities of super and measure the extra yield.

This article discusses the recommended rates of superphosphate in relation to soil type and superphosphate history. Methods of application and time of topdressing are also discussed.


Coccidiosis In Lambs On The South Coast, A J. Hadlow Jan 1969

Coccidiosis In Lambs On The South Coast, A J. Hadlow

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

Outbreaks of coccidiosis among autumn-born lambs on the south coast have approached epidemic proportions this year.

Lupins In Western Australia. 1. Species And Varieties, John Sylvester Gladstones Jan 1969

Lupins In Western Australia. 1. Species And Varieties, John Sylvester Gladstones

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

First in a series of articles on the varieties, cultivation and uses of lupins in Western Australia.

Lupins are ideally suited to the climate and soils of many districts of Western Australia and their cultivation here dates from the early years of the century.

However, although there were some 500,000 acres of lupins growing in the State in 1968, their cultivation in recent years has been largely limited to infertile sandplain soils where other legumes usually fail.


Breeding Better Pigs, B M. Goss Jan 1969

Breeding Better Pigs, B M. Goss

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

IN the past, pig breeders have tended to select animals on physical characteristics, many of which have little or no relevance to economy of production.

Selection techniques now available open up the possibility of improved pig production efficiency.


Lupins In Western Australia. 2. Cultivation Methods, John Sylvester Gladstones Jan 1969

Lupins In Western Australia. 2. Cultivation Methods, John Sylvester Gladstones

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

While lupins are by and large plants of lighter and less fertile soils, important differences exist among them in their soil preferences.

There may also be some differences in climatic requirements. Present knowledge of these differences is summarized in the Table below.

Wildflowers Of The Stirling Range, Alexander S. George Jan 1969

Wildflowers Of The Stirling Range, Alexander S. George

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

TWO hundred miles south-east of Perth, the Stirling Range rises abruptly from the surrounding plain. About forty miles long, it is a line of semi-isolated hills, rather than a continuous block.

There are many intriguing plants of diverse colour and form. Well over 400 species are known from the Range. A number of these are found no-where else, and some are restricted to one mountain.


Black-Leg In Cattle, F C. Wilkinson Jan 1969

Black-Leg In Cattle, F C. Wilkinson

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

BLACK-LEG is still a serious disease of cattle in the South West coastal region, causing deaths in young cattle.

The disease is characterised by hot swollen muscles, acute lameness and rapid death.

Cattle affected are usually 6 to 12 months old, in fat condition, and grazing on lush pastures.


The Control Of Weeds In Cereals, Geoffrey A. Pearce Jan 1969

The Control Of Weeds In Cereals, Geoffrey A. Pearce

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

PRACTICALLY all broadleaved weeds found in cereals can now be killed with herbicides and with most, the farmer has a choice of chemicals.

Two more new products are now available and these have several advantages over other herbicides.


Dormancy And Life Span Of Saffron Thistle Seeds, B J. Quinlivan, J. R. Pierce Jan 1969

Dormancy And Life Span Of Saffron Thistle Seeds, B J. Quinlivan, J. R. Pierce

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

RESEARCH in the Geraldton area has indicated that seeds of the saffron thistle (Carthamus lanatus) spread their germination over some seven years but most germinate in the first two years.

Factors influencing the rate of germination and the survival of seeds are the depth of burial and the presence of termites in the soil.
