A Land Resource Survey Of The Fall Point Coastline, Broome, W.A., P A. Hesp, P J. Curry

Resource management technical reports

The purpose of this study was to find a suitable location for a bird observatory and provide adequate coastal land resource data for the area. The main selection criteria and conditions were: the location was closely adjacent to major wader roosting and feeding sites; all-seasons access was required; the location provided a site of around 2 1/2 hectares to provide space for one or more buildings, camp ground and associated facilities ; anticipated access tracks, site developments and levels of use.

Fungicidal Control Of Wheat Leaf Diseases, A G P Brown

Experimental Summaries - Plant Research

In a further experiment on fungicides to protect wheat during flowering and grain fill from Septoria nodorurn at Badgingarra Research Station, rates below 1 litre and lower carrier volumes were compared for the fungicide Tilt applied at Zadoks stage 50. A few other fungicides were also included. At spraying there was a moderate infection by Septoria nodorurn (85% of leaf damage), Septoria tritici (10%) and Pyrenophora tritici-repentis (5%). Good control was obtained with most treatments (Table 1) with only Benlate at 1 kg/ha appearing ineffective when percentage disease was rated on October 10, 1985. At October 17 disease scores differed …

Eradicating Fruit Fly From Carnarvon, Kingsley Thomas Fisher

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

Late last year the Mediteranean fruit fly (Ceratitis capitata Weidemann) was eradicated from Canarvon, Western Australia by using an intergrated programme of sterile insect releases and bait spraying.

The eradication marked the end of a four-year study on the use and effectiveness of the Sterile Insect Technique, a biological control technique which uses an insect pest against itself. such a study can be used as a basis for treating other threatening insect pests, such as the serious cattle pest screw-worm fly, should they be found in Asustralia.

Being a biological control method, the Sterile Insect Technique is an exellent …

A Survey Of Drench Resistance In Sheep Worms, J R. Edwards, R. Wroth, G. C. De Chaneet, R. B. Besier, J. Karlsson, P. W. Morcombe, D. Roberts, G. Dalton-Morgan

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

Sheep worms which are resistant to chemical drenches have been detected with increasing freuency is Western Australia's south-western farming areas between 977 and 1980. These worms have anthelmintic resistance and such genetis resistance puts essential internal parasite control practices at risk.

This prompted veterinarians in the Esperance, Albany, Bunbury, Geraldton and Northam areas to survey farms to determine the prevalence of resistance to drenches and to define those sheep management practices which encourage its development.

This article describes the survey which was conducted to assess the extent of drench resistance, what causes its build-up and how it can be controlled …

The Economic Potential Of Cashmere Production, A T. Kelly

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

Although the cashmere industry has developed rapidly in eastern Australia, development in Western Australia has lagged behind because of local restrictions on the use of feral goats. However, recently the Agricultural Protection Board has eased these restrictions.

In Western Australia there are about 30 to 40 producers with commercial cashmere flocks, involving a total of 7,500 to 10,000 goeats. In most agricultural areas where sheep production occurs, cashmere production is also possible.

In the following article, A. T. Kelly, an adviser with the Marketing and Economics Branch, discusses the economic potential of cashmere production in this State and compares …

Interceptor Drains And Waterlogging Control, J W. Cox, T R. Negus

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

Department of Agriculture trials of seepage interceptor drains from 1972 to 1983 primarily assessed the effects of such drains on salt encroachment. Although these trials showed that the drains had little influence on salt storage within the topsoil, they did reduce waterlogging downslope.

To investigate this drainage effect further, the Department's Narrogin office surveyed 35 drains on 14 properties in the winter of 1981, followed by detailed crop measurements in December that year. Provided the drains were properly designed, surveyed and constructed, and well maintained, they could be expected to increase crop yields during a waterlogging year by about 1 …

Farm Debt In The Wheatbelt : 1984 Survey Results, R S. Kingwell

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

In recent years many farms in Western Australia's wheat-growing areas have experienced adverse seasons. For example, the 1983-84 season was characterised by a late start, dry spring and wet harvest which resulted in many farms suffering a combination of low yields and the downgrading or dockage of their grain.

Poor seasons and poor profitability prospects for wheat-growing caused some concern about farm indebtedness in these areas.

In late 1983, a Parlimentary select committee was appointed to inquire into rural hardship. The State Minister for Agriculture also announced that the Department of Agriculture would conduct a farm survey to determine the …

Camballin Irrigation Area : A Summary Of Cropping And Pasture Studies 1958-1970, Phongsak Yuhun

Resource management technical reports

The Camballin Irrigation Area was the first large scale rice growing area in Western Australia. It was hoped Camballin would develop into a highly productive irrigation area. The Department of Agriculture was directly involved in the area between 1958 and 1970. The report summarizes the research carried out during the period which paralleled the commercial operation. The trials were designed to solve the specific cropping problems encountered over the period.

A Preliminary Report On Work Conducted In 1985 To Evaluate Plantago Ovata As A Potential Crop In The Ord River Irrigation Area, D. L. Mcneil

All other publications

This paper reports on the first year of a 3 year programme aimed at developing P. ovata as a crop in the Ord River Irrigation Area (O.R.I.A.) of Kimberley region of Western Australia. The data from one year of trials indicate that Plantago ovata is highly suited to mechanisation and the Ord River Irrigation Area (ORIA). Machine harvested yields of up to 1.2 t/ha off 0.12 ha were achieved (after cleaning). The maximum hand harvested yield was 2.1 t/ha, 60 per cent higher than any other published value. Cununurra clays proved the best soil type for growth of the crop …

The Taarblin Experience : A Planned Approach To Soil Conservation, Greg Astbury, Owner/Manager Of Taarblin, Tim Negus

Bulletins 4000 -

Many farms in Western Australia were cleared and developed before there was a full and clear understanding of the effects of bush clearing - that is salinization of soil and water supplies, wind and water erosion, waterlogging and soil structure decline. The productive capacity and inherent problems of the different soil types was also largely unknown.

Modern-day Conservation Farm Planning aims to provide a blue-print for the redevelopment of properties to ensure long term soil fertility, to prevent soil erosion and degradation by waterlogging and salinity. It also provides for a spread of reliable stock watering points and more efficient …
