High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan Jan 1969

High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan

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

KIKUYU is one of the most valuable pasture plants on dairy farms in the South-West of Western Australia.

It combines well with subterranean clover and ryegrass if heavily stocked, and pastures managed in this way can be cut for legume-grass hay in the spring. However, relatively little is known of its carrying capacity or potential for production under grazing.


More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia Jan 1969

More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia

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

STOCKING rates on dairy farms are generally too low and can be substantially increased, but unfortunately there is no satisfactory measurement to indicate the potential of a particular pasture or environment.

A trial carried out on Denmark Research Station in 1966-67, to obtain information on carrying capacity of a dryland kikuyu-subterranean clover pasture.


A Comparison Of Methods Of Urea Application At Ajana, M G. Mason, R. J. Parkin, H. Patrick Jan 1969

A Comparison Of Methods Of Urea Application At Ajana, M G. Mason, R. J. Parkin, H. Patrick

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

Compared with urea application separate from the seed, urea mixed with wheat seed delayed and reduced wheat germination, and reduced wheat yields, especially at high rates of urea.

Yields were higher where the urea was topdressed immediately before seeding than where it was top-dressed either immediately after, or two weeks after seeding.


Maintenance Phosphorus And Sulphur For Pastures : Progress Report, Walter Jacob Cox Jan 1968

Maintenance Phosphorus And Sulphur For Pastures : Progress Report, Walter Jacob Cox

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

PASTURE IMPROVEMENT has been based on topdressing with superphosphate, which supplies sulphur as well as phosphorus.

In the past, all the benefit due to superphosphate was attributed to the phosphorus.

It is only in recent years that the importance of the sulphur has been appreciated.


West Midlands Development : Fertilizers For The West Midlands, Department Of Agriculture, Western Australia Jan 1968

West Midlands Development : Fertilizers For The West Midlands, Department Of Agriculture, Western Australia

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

FARMING the light lands of the West Midland area would be impossible without fertilisers.

Most light land areas are inherently very low in phosphate and also require nitrogen.

The nitrogen can come from fertiliser for cereal crops, or can be built up by growing appropriate legume pasture plants such as clovers and lupins.


West Midlands Development : Cereals For The West Midlands, Department Of Agriculture, Western Australia Jan 1968

West Midlands Development : Cereals For The West Midlands, Department Of Agriculture, Western Australia

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

THE sandplain soils and climate of the West Midlands area are primarily suited to grazing.

However, the place of cereals is receiving a great deal of attention in view of their advantages in the early stages of development, and the need for the diversification of farm production.


Fertiliser Responses With Newly Planted Apple Trees, N H. Shorter Jan 1968

Fertiliser Responses With Newly Planted Apple Trees, N H. Shorter

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

AN outstanding response to phosphate and a worthwhile response to nitrogen have been obtained in the Donnybrook area on a new orchard site on the property of Mr. A. Cross of Argyle.

Rates Of Superphosphate For Pasture And Crop Production In The Salmon Gums District, R N. Glencross, W. J. Cox

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

DURING the last few years large areas have been released for cereal and pasture production in the southern part of the Shire of Dundas and the northern part of the Shire of Esperance.

Changes in land use since 1962 are summarised in Table 1.


Rates Of Superphosphate For Cereal Grain Production In The Under 20 Inch Rainfall Areas, Walter Jacob Cox Jan 1968

Rates Of Superphosphate For Cereal Grain Production In The Under 20 Inch Rainfall Areas, Walter Jacob Cox

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

EVERY year farmers use large quantities of superphosphate with cereal crops to overcome the inherent phosphate deficiency of West Australian soils.

The increase in the average rate used by farmers reflects the increasing amount of new land being cropped.

Good seasons and favourable economic conditions may also have influenced super rates.


Fertilisers For The Wheatbelt, William John Toms Jan 1967

Fertilisers For The Wheatbelt, William John Toms

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

A review of fertiliser research findings and recommendations for fertiliser applications to crops and pastures in the 12 to 15 inch rainfall areas.

NOT long ago, fertiliser to the cereal grower meant only superphosphate for cropping. Today, phosphorus, sulphur, nitrogen, copper, zinc and molybdenum are all important, and the needs of improved pastures must be considered as well as those of cereals.


Cattle Stocking Rates In A Higher Rainfall Area, R Sprivulis Jan 1967

Cattle Stocking Rates In A Higher Rainfall Area, R Sprivulis

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

THE 1965 Pardelup cattle stocking rate trial was conducted with Hereford cross yearling steers on annual pasture of Mt. Barker sub. clover, Wirnmera ryegrass and various volunteer annual species.

This was topdressed with 186 lb. of superphosphate per acre in mid March.


Meadow Hay For The Dairy Herd, F E. Ryan Jan 1966

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.


Continuous Grazing On Rose Clover At Northampton, R J. Parkin Jan 1966

Continuous Grazing On Rose Clover At Northampton, R J. Parkin

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

BECAUSE of its upright growth habit, it is often thought that rose clover may require some form of specialised grazing management.

It has also been said that the sheep find the plant and in particular the seed head, undesirable in the dry stages.

However, more recent observations refute this (Bailey 1966). The present commonly-grown strains of rose clover are later flowering generally than the medics or Geraldton subterranean clover and stay green later in the season.


Stocking Rates On Cyprus Barrel Medic In The Northern Wheatbelt, R J. Parkin Jan 1966

Stocking Rates On Cyprus Barrel Medic In The Northern Wheatbelt, R J. Parkin

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

IN May 1963, some three weeks after germination, a 4th year stand of Cyprus barrel medic was stocked with Merino wethers.

These same sheep are still grazing the area after three years.

Dairy Farming In The Busselton-Margaret River District. Part 3. Fodder Conservation, R A. Bettenay

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

An analysis of fodder conservation indicates that farmers in the Busselton-Margaret River district are conserving less than half the amount of fodder considered desirable.—Third in a series reporting a survey of farm practices in the district.


Dairy Farming In The Busselton-Margaret River District. Part 4. Pasture Production, R A. Bettenay Jan 1965

Dairy Farming In The Busselton-Margaret River District. Part 4. Pasture Production, R A. Bettenay

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

If deteriorated pasture and underdeveloped pasture in the Busselton-Margaret River district could be improved to the standard of the present highly productive pastures stocking rates could be improved by more than 50 per cent.—final article in a series reporting the results of a survey of farm practices in the district.


Phosphate Requirements Of Rice In The Ord River Valley, Rijn P J Van, A. L. Chapman Jan 1964

Phosphate Requirements Of Rice In The Ord River Valley, Rijn P J Van, A. L. Chapman

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

A three-year experiment on the initial and maintenance phosphate requirements of wet-season rice was carried out at Kimberley Research Station between 1960 and 1963.

Application of 2 cwt. per acre superphosphate as the first application on new land, followed by annual application of 1J cwt. per acre is recommended.


Range Feeding Of Cotton By-Products In The Kimberleys, John Hubert Auty Jan 1964

Range Feeding Of Cotton By-Products In The Kimberleys, John Hubert Auty

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

Commercial cotton production has started in the Ord River area and by-products of the industry will soon be available for stock feeding in the surrounding pastoral areas.

Cotton seed and cotton seed meal will cause digestive upsets if fed in any quantity to horses, poultry or pigs.

Ruminants have no trouble in handling the material and the Kununurra ginnery could supply a useful protein supplement for Kimberley cattle.


Meadow Hay, Department Of Agriculture, Western Australia Jan 1962

Meadow Hay, Department Of Agriculture, Western Australia

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

rriHE nutritive value of pasture is high in early spring and remains so until early flowering.

After this the protein content falls rapidly, the fibre content rises and the plants become more lignifled and their digestibility reduced.

Fertiliser Trials With Potatoes, Manjimup : 1958-1959, T Wachtel

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

THIS experiment was the third of this type carried out in karri loam soils.

Significant yield responses were obtained from increasing rates of fertiliser applications.

The results appear to be generally consistent with those obtained previously in the area.


Fertilizers For Potatoes In Manjimup And Pemberton Areas, James P. Fallon Jan 1961

Fertilizers For Potatoes In Manjimup And Pemberton Areas, James P. Fallon

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

IN articles published in previous issues of the Journal each of a number of potato fertiliser trials carried out in the Manjimup and Pemberton districts has been discussed and results reported.

This article briefly summarises the results of these trials carried out over the past four years and makes definite recommendations to potato growers in these districts regarding quantities of fertilisers to be used on new Red Karri loam soils.


Tree Lucerne : A Fodder Crop With A Future, Laurence C. Snook Jan 1961

Tree Lucerne : A Fodder Crop With A Future, Laurence C. Snook

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

IN December, 1952, an article was published in this Journal drawing attention to the potential value of white flowered tree lucerne (Cytisus prolifer) as a source of nutritious green fodder during the dry summer months.

Figures were quoted to show that heavy yields could be obtained year after year with very little effort, and no outlay other than for fertiliser.

The advantages to be gained from the cultivation of this tree were made very apparent and many farmers set out to grow the shrub.


Studies In The Mulga Pastoral Zone. 2. Some Aspects Of The Value Of The Mulga Scrub, D G. Wilcox Jan 1960

Studies In The Mulga Pastoral Zone. 2. Some Aspects Of The Value Of The Mulga Scrub, D G. Wilcox

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

THE mulga pastoral zone is so named since most of its area is dominated by Mulga (Acacia aneura).

The mulga is found associated with shrubs and grasses in almost all plant habitats. In its various forms it can associate with spinifex (Triodia basedowi), Wandarrie Grasses (Danthonia, Eragostis and Eriachne spp.) and with low shrubs on flood plains, hills and breakaways. It may even attempt to become established in salty communities, though this is never completely successful.

The scene the area offers from its low hills is one of a succession of low undulations, occasionally scarred by creeks or breakaways and …
