Stocking Rate And Rate Of Superphosphate In A Higher Rainfall Area, P P. Mann, B. J. Gorddard, R. N. Glencross, E. N. Fitzpatrick
Stocking Rate And Rate Of Superphosphate In A Higher Rainfall Area, P P. Mann, B. J. Gorddard, R. N. Glencross, E. N. Fitzpatrick
Journal of the Department of Agriculture, Western Australia, Series 4
In its virgin state the area carried a forest association of red-gum and jarrah, and the soils are typical of large areas in the south-west of Western Australia.
These gravelly soils have a high requirement for phosphate during their first years under pasture, and this trial was designed to investigate the relationship between rate of phosphate, stocking rate and pasture production over a number of seasons.
Summer And Autumn Rainfall In Relation To Epidemics Of Wheat Stem Rust In Western Australia, W A. Shipton
Summer And Autumn Rainfall In Relation To Epidemics Of Wheat Stem Rust In Western Australia, W A. Shipton
Journal of the Department of Agriculture, Western Australia, Series 4
High summer and autumn rainfalls, followed by rust infection of volunteer plants and favourable conditions during late winter and spring, lead to rust epidemics.
WIDESPREAD outbreaks of wheat stem rust are rare in Western Australia.
The Recent Story Of Skeleton Weed : A Menace To Our Wheat Industry, G R W Meadly
The Recent Story Of Skeleton Weed : A Menace To Our Wheat Industry, G R W Meadly
Journal of the Department of Agriculture, Western Australia, Series 4
SKELETON WEED was first found in Western Australia at Ballidu in 1963.
No further recording was made until December of last year when a small area was located near Esperance, but, within a brief period, plants were reported from Geraldton and Kwinana.
Cereal Variety Testing : A New Approach, H M. Fisher
Cereal Variety Testing : A New Approach, H M. Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
One hundred and twenty large scale trials will be planted at 38 centres in the Department of Agriculture's expanding cereal variety testing programme.
ACCORDING to statistical returns West Australian farmers grow well over 100 varieties of cereals. More than 80 of these are different varieties of wheat.
Only a few varieties are widely grown so one might ask why farmers continue to grow so many of the less popular types.
The obvious answer is that they believe such varieties to be both suitable and profitable for their particular conditions.
Meadow Hay For The Dairy Herd, F E. Ryan
Meadow Hay For The Dairy Herd, F E. Ryan
Journal of the Department of Agriculture, Western Australia, Series 4
CONSERVATION is the basis of progress in dairy farming and the major form is meadow hay, but unfortunately relatively few dairy farmers give enough attention to the quality and quantity of this important feed.
Pasture Seed Production, 1966 : Statistics And Comments, B J. Quinlivan
Pasture Seed Production, 1966 : Statistics And Comments, B J. Quinlivan
Journal of the Department of Agriculture, Western Australia, Series 4
THE marketing of pasture seeds differs from that of some other primary products in that there are no guaranteed prices.
A knowledge of potential supply and demand for the various species and strains is just as important to the seed producer as good production techniques.
Black Spot Of Peas, Department Of Agriculture, Western Australia
Black Spot Of Peas, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
THIS fungous disease of peas causes "black spot" and "stem rot" on affected plants. During the wet winter months the disease is often so severe that it is difficult to grow garden pea varieties satisfactorily; but in summer when hot, dry conditions usually prevail the disease is of little consequence.

Agriculture In Williams-West Arthur : Report Of A Survey Of Farm Practices, A W. Hogstrom
Journal of the Department of Agriculture, Western Australia, Series 4
THIS article summarises the results of a survey of 81 farms in the Williams and West Arthur Shires, carried out by officers of the Department of Agriculture at the request of the Central South Zone Development Committee.
Field work for the survey started in 1961.

LARGE scale irrigation in the south-western part of Western Australia is confined to the coastal plain, west of the Darling Range where the three irrigation districts of Waroona, Harvey and Collie have been established.
Rose Clover, E T. Bailey
Rose Clover, E T. Bailey
Journal of the Department of Agriculture, Western Australia, Series 4
Description, use, and varietal differences of rose clover in Western Australia.
ROSE CLOVER is a native of Asia Minor and the Mediterranean region.
Until recently, it was used only as a sown pasture in California.
Its commercial use dates back to 1949, after five years of range plot trials (Love and Sumner), but even though the species has been in commercial use for 16 years, no attempt seems to have been made to develop uniform lines from the very mixed seed in common use.
Early Spraying Esential For Webworm Control, J A. Button
Early Spraying Esential For Webworm Control, J A. Button
Journal of the Department of Agriculture, Western Australia, Series 4
Results of trials conducted during the last two seasons have emphasised the need for very early treatment of webworm infested crops.
Where heavy infestations occur every effort should be made to apply treatments during the first fortnight after crop emergence
Strains Of Stem And Leaf Rust On Wheat In Western Australia Since 1951, I A. Watson, W. P. Cass Smith, W. A. Shipton
Strains Of Stem And Leaf Rust On Wheat In Western Australia Since 1951, I A. Watson, W. P. Cass Smith, W. A. Shipton
Journal of the Department of Agriculture, Western Australia, Series 4
THE most important wheat rust in Western Australia is stem rust,
Leaf rust occurs infrequently and has not been known to cause serious damage.

NET BLOTCH is the most prevalent disease of barley in Western Australia, and is capable of reducing yields considerably.
It is caused by the fungus Pyrenophora teres Drechsl.

Journal of the Department of Agriculture, Western Australia, Series 4
THE financial results of 18 cotton growers in the Ord River Valley during the 1965 season were obtained during a survey conducted in August, 1965.
All farmers who have been allocated blocks and who grew cotton in 1965 were included in the survey.*
Cultivation : Does Haste Mean Waste?, H M. Fisher
Cultivation : Does Haste Mean Waste?, H M. Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
Many farmers believe that increasing the speed of cultivation and seeding implements will cause deterioration of soils and reduced crop yields.
In a three-year trial on clover ley land at Wongan Hills higher cultivation speeds tended to increase rather than decrease wheat yields. There was some deterioration in the physical structure of the soil.
