Linseed Production Survey : Esperance, 1968, R J. Guyton
Linseed Production Survey : Esperance, 1968, R J. Guyton
Journal of the Department of Agriculture, Western Australia, Series 4
A SURVEY conducted after the 1967 linseed season found that although most farmers understood the requirements of linseed growing there were several crop failures. These were associated with time of planting, soil type and insect control measures.
The Esperance district office of the Department of Agriculture conducted a second survey during December, 1968 and January, 1969

The Agricultural Potential Of Owingup Swamp. 1. Soil Survey Of Owingup Swamp. 2. Comparison Of Owingup And Grasmere Swamps, L T. Jones, C V. Malcolm, James P. Fallon, Department Of Agriculture And Food, Western Australia
Technical Bulletins
The two swamps, Owingup and Grasmere are practically identical with regard to soil conditions. Grasmere swamp however has been cleared and used for agriculture for some 60 years while Owingup swamp is as yet unalientated. Soils on both swamps consist of mainly organic diatomaceous clay. Findings of the survey indicate that some 2000 acres at Owingup swamp would be suitable for vegetable growing following clearing and draining.

Time Of Application Of Solid Nitrogen Fertilisers., M G. Mason
Time Of Application Of Solid Nitrogen Fertilisers., M G. Mason
Experimental Summaries - Plant Research
The current recommendations for time of application of soild nitrogen fertilisers such as urea, ammonium nitrate and sulphate of ammonia are:
Zone A: These fertilisers should be applied as close to seeding as possible.
Zone B: As for zone A except on very sandy soils which are very prone to leaching, where application can be delayed 2-3 weeks.
Zone C: Applications should be delayed about 3 weeks after seeding.

No meaningful conclusions can be drawn until the multiple regression analysis comparing soil and plant parameters with level of response has been completed. Similarly it is extremely dangerious to extrapolate results obtained from any one experiement in a particular district to the general farm situation. In addition these results represent only 1 rather atypical season and so need to be verified by additional calibration trials. in 1973 (40) and 1974 (20).

Nitrogen Use On First Crops After Legume Pasture, M G. Mason
Nitrogen Use On First Crops After Legume Pasture, M G. Mason
Experimental Summaries - Plant Research
Apart from the normal factors affecting response of cereals to nitrogen fertilizers, i.e. length of growing season, rainfall, soil type etc, there are other factors which affect the response after a legume pasture. these factors include length of the previous legume phase and how good was the stand of legumes. Unfortunately for most of the trials in the past, involving the use of nitrogen on first crops after legumes, this information is not available.

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

Journal of the Department of Agriculture, Western Australia, Series 4
RESULTS of a survey on water storage capacity in the South Stirlings area indicate that farm water storage has not kept pace with increased clearing and stock numbers.
This has resulted in many farmers requesting advice on water conservation projects following two consecutive years of low rainfall runoff.

Pasture Improvement In South Western Australia, J W. Malcolm
Journal of the Department of Agriculture, Western Australia, Series 4
"There is no doubt that Australia's enhanced prosperity in the last 30 years has been dependent in no small measure on the use of legume-based pastures." E. M. Hutron, June, 1968. *
THE LAST 30 years have seen an increased interest in pasture improvement which has transformed much of Western Australia. Large areas have been sown to new and improved pasture species—as a result productivity of both livestock and cereal enterprises has risen.

Ammonium Nitrate Vs Urea, M G. Mason
Ammonium Nitrate Vs Urea, M G. Mason
Experimental Summaries - Plant Research
Ammonium nitrate is a source of nitrogen containing half
its nitrogen in the ammonium form and half in the nitrate form.
Some properties are set out in comparison with urea in the
following table.
Ammonium nitrate has an advantage over urea in that it can
be topdressed onto the surface of the soil and left uncovered
without a danger of loss of nitrogen to the atmosphere. When urea
is left uncovered on the surface of the soil losses of nitrogen occur
through volatilisation of ammonia during the hydrolysis of the urea.
Such losses with ammonium nitrate are only likely to …

History Of The State Vermin Barrier Fences, Formerly Known As Rabbit Proof Fences, J S. Crawford
Research Reports
There is evidence of rabbits arriving in Australia as far back as 1788, and it is well known that others were liberated on islands around the coast, including some off the coast of Western Australia. However, they remained localised and it is now generally accepted that the rabbits which did spread originated from a small shipment of the wild type brought on the Clipper “Lightning” in 1859. They were released on “Barwon Park”, the property of Thomas Austin, near Geelong in Victoria, and within three years, had reached pest proportions

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.
Pastures For The Pastoral Areas, D G. Wilcox, K. Fitzgerald
Pastures For The Pastoral Areas, D G. Wilcox, K. Fitzgerald
Journal of the Department of Agriculture, Western Australia, Series 4
The pastoral areas lie generally outside the zone where cultivated crops are grown.
The rainfall is erratic and the basic pastures for sheep and cattle consist of native plants.
In some favoured areas however, and in particular situations, sown pasture species are becoming increasingly important.
Flora And Fauna Conservation : A Plea To Landholders, Clee Francis Howard Jenkins
Flora And Fauna Conservation : A Plea To Landholders, Clee Francis Howard Jenkins
Journal of the Department of Agriculture, Western Australia, Series 4
MUCH of the recent discussion on conservation has centred around the importance of wild flower reserves and the necessity for protecting one of the State's most important tourist attractions.
Although less important to visitors than the flowers, many of our wild animals hold equal interest for nature lovers and scientists, and they also need protection.
Pasture Establishment In The Wheatbelt, M L. Poole
Pasture Establishment In The Wheatbelt, M L. Poole
Journal of the Department of Agriculture, Western Australia, Series 4
The value of legume based wheatbelt pastures is so great that considerable care is warranted during their establishment. Without such care patchy establishment or even complete failure is likely to occur.
IN THE WHEATBELT too many farmers still put less effort into their seeding of pasture species than their seeding of crops.
This may be because both compete for the farmer's time in the busy seeding period and it is the cereal crop which possesses the obvious cash value.
However, the total value of a good pasture has to be assessed over a period of several years because of its …
Continuous Cropping Trials, M G. Mason
Continuous Cropping Trials, M G. Mason
Experimental Summaries - Plant Research
The aims of the trials at Binnu, Chapman, Wongan Hills, Avondale and Merredin were:
- To determine whether the application of nitgrogen and fertilisers can maintain yields under a "continuous cropping" system
- To compare the merits of three sources of nitrogen for this purpose.
- To determine the maintenance dressing of superphosphate under this system and the need for supplementary fertilisers.
Trial 61A2
There have been no great problems with this trial. for a number of years the plots have required chemical spraying to control wild oats which had built up. In 1968 and 1969 some plots were soil sampled to determine …
Honey Plants In Western Australia, F. G. Smith
Honey Plants In Western Australia, F. G. Smith
Bulletins - 3000 - 3999
Successful honey production depends, among other things on a good knowledge of the plants which produce nectar.
Every apiarist needs to know which plants are of importance to honey-bees, where those plants occur, and when they flower. He also needs to know which plants produce nectar which will result in the production of good quality honey, and which produce unpalatable or unmarketable honey. To maintain the strength of his bee colonies he also needs to know which plants produce nutritious pollen.
The object of this bulletin is to provide the basic information on these subjects in the main beekeeping areas …
