Weed Control Research Pays Dividends, G R W Meadly Jan 1970

Weed Control Research Pays Dividends, G R W Meadly

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

On my bookshelf is a handbook entitled "War on Weeds" or "How to Double our Food Supply."

In many of these countries experiments have been made to ascertain as far as possible the exact damage done by weeds to crops.

Result: In all the experiments, whether made in England or abroad, the mean loss was over 50 per cent.

The level of loss is equally true today, but the methods at our disposal for handling weeds have improved tremendously.

Lupins In Western Australia. 6. Future Prospects, John Sylvester Gladstones

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

PREVIOUS articles in the series have discussed available lupin varieties, their cultivation, and the feed value of the seeds and crop residues.

This final article for the series deals with future prospects for lupin varieties and markets, and how lupins might fit into Western Australian farming systems.


Growing Barley For Grain In Western Australia : Barley Quality, J A. Parish Jan 1970

Growing Barley For Grain In Western Australia : Barley Quality, J A. Parish

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

Plumpness and absence of pinched grain are desirable for both malting and feed barley.

This is a brief discussion of various Quality standards in barley and how they may not be met.


Urea Drilled With Seed Affects Germination And Yield, M G. Mason, A. Loutit, J. A. C. Smith, D. Highman, P. Stallwood Jan 1970

Urea Drilled With Seed Affects Germination And Yield, M G. Mason, A. Loutit, J. A. C. Smith, D. Highman, P. Stallwood

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

Trials in 1968 at Burracoppin and York again showed it is safer to topdress urea just before seeding than to drill a mixture of seed and urea.

At all but the lowest urea rates, urea drilled with the seed reduced the number of plants emerging and surviving, and reduced final wheat yields.


Linseed : An Alternative Crop For The South Coast. 2. What Is The Future For Linseed?, R J. Doyle, R. J. Guyton Jan 1970

Linseed : An Alternative Crop For The South Coast. 2. What Is The Future For Linseed?, R J. Doyle, R. J. Guyton

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

In a preceding article* we stated that the expansion of linseed in Western Australia was due primarily to the ability to sell on the export market at current ruling prices.

This is necessary because Australia's domestic needs are likely to be supplied in most years by Eastern States producers.


Recommended Crop Varieties, Department Of Agriculture, Western Australia Jan 1970

Recommended Crop Varieties, Department Of Agriculture, Western Australia

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

RESULTS of variety trials carried out in 1968 by the Department of Agriculture were considered by the State Wheat Advisory Committee and the State Coarse Grains Advisory Committee in making recommendations on leading varieties of wheat, oats and barley.

Details of the recommendations are set out below.

Recommendations on linseed varieties have been included in view of the growing significance of the industry and representations from farmers for consideration of this crop along with the cereals.


Nitrogen Fertiliser Survey, Department Of Agriculture, Western Australia Jan 1969

Nitrogen Fertiliser Survey, Department Of Agriculture, Western Australia

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

THE DECEMBER, 1968 issue of the "Journal of Agriculture" included, as part of an article on the economics of nitrogen fertiliser use, a lift-out section for farmers to complete and return to the Journal.

In the lift-out, farmers were asked to calculate their fertiliser costs and answer a series of questions about the use of nitrogen on their farms.


Simple Treatment Will Protect Farm-Stored Grain, Department Of Agriculture, Western Australia Jan 1969

Simple Treatment Will Protect Farm-Stored Grain, Department Of Agriculture, Western Australia

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

WITH unusually large quantities of grain likely to be stored on farms this season, 1970 will be an important year for the control of pests in stored grain.

Infested grain from farms is responsible for almost all outbreaks of infestation in bulk storages, leading to costly treatment by the grain handling authority. Effective control on the farm would eliminate most of this.


Weed Control In Pastures : A Practical Approach For Sheep Areas, Geoffrey A. Pearce Jan 1969

Weed Control In Pastures : A Practical Approach For Sheep Areas, Geoffrey A. Pearce

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

IN the past, chemical treatments for the control of weeds in pastures have been costly and severe on pasture, and have had to be repeated over a number of years. The method outlined in this article overcomes nearly all these disadvantages.


Costs Of Grain Storage On Farms, P J. Hackett Jan 1969

Costs Of Grain Storage On Farms, P J. Hackett

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

GRAIN storage on farms has been commonly practised for intensive livestock production, for feed reserves, for seed purposes, and more recently to store excess grain.

For most of these purposes permanent storage facilities are required.


Linseed : An Alternative Crop For The South Coast, R J. Doyle, R. J. Guyton Jan 1969

Linseed : An Alternative Crop For The South Coast, R J. Doyle, R. J. Guyton

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

IN the over-17 inch rainfall zone of the south coast region of Western Australia animal production is the main farm enterprise.

Although farmers in the main cereal growing regions of W.A. crop about one-third of their cleared land each year, farmers in the south have been reluctant to crop more than about 12 per cent, of their cleared area.

Rollins Adams Emerson (1873-1947) Horticulturist Pioneer Plant Geneticist Administrator Inspiring Student Adviser, Rosalind Morris

Department of Agronomy and Horticulture: Faculty Publications

The vigorous and highly productive life of Professor R. A. Emerson spanned 74 years and 7 months. His birth and death took place In New York State, but Nebraska nurtured his early development and schooling. He spent 15 years of his professional career at the University of Nebraska, followed by 33 years at Cornell University.

Rollins Adams Emerson, son of Charles David and Mary C. Adams Emerson (a direct descendant of Henry Adams), was born May 5, 1873 at Pillar Point, New York State on the eastern shore of Lake Ontario. In 1880 his family moved to Nebraska and settled …


Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson Oct 1968

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson

Bulletins - 3000 - 3999

Interest in the development of light lands in the south-eastern wheatbelt was spurred by the many ex-servicemen seeking farms after the 1939-45 World War.

Previous attempts to develop this area had been frustrated by poor crop yields, and by the poor carrying capacity of those volunteer pastures which developed on cleared land.

Research into reasons for the poor crop results was begun in 1948-49 with trials sown by Messrs Smith and Halpin between Borden and Lake Grace. The results clearly showed the important role played by copper and zinc in successful crop growth. Since then, field trials have been conducted …


Nitrogenous Fertilisers For Cereal Production, M G. Mason Jan 1968

Nitrogenous Fertilisers For Cereal Production, M G. Mason

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

THE greatest responses to nitrogenous fertilisers can be expected in areas with a relatively long growing season.

In such areas light soils with a low nitrogen status provide the best prospects for addition of nitrogen—provided adequate moisture is available.


Wheat In Development Programmes For New Esperance Farmers, R J. Doyle, G. D. Oliver Jan 1968

Wheat In Development Programmes For New Esperance Farmers, R J. Doyle, G. D. Oliver

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

IN the December, 1967, issue of the Journal of Agriculture, we reported on five development budgets for the Esperance region.

The aim of the exercise was to find out if a new settler concentrating on sheep, with $20,000 available for development after acquisition of land, could make a reasonable living for himself and his family while developing his farm.


New Strains Of Subterranean Clover : Prospects And Problems For The Seed Producer, B J. Quinlivan Jan 1968

New Strains Of Subterranean Clover : Prospects And Problems For The Seed Producer, B J. Quinlivan

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

THREE new strains of Subterranean clover—Daliak, Seaton Park and Uniwager—have been released.

In Western Australia, in other States and perhaps some overseas countries, the next few years will see many farmers or graziers summing up the merits and demerits of these strains and subsequently making a decision to change or not to change their present strains.


Trials With Urea And Anhydrous Ammonia For Wheat Growing, M G. Mason Jan 1968

Trials With Urea And Anhydrous Ammonia For Wheat Growing, M G. Mason

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

THE recent subsidy on nitrogenous fertilisers has greatly reduced their price to farmers. This, and farmers' increasing awareness of the benefits of application of nitrogen to cereals, has led to a substantial increase in the use of these fertilisers.


Wheat Weevil And The Farmer, Clee Francis Howard Jenkins, G. D. Rimes Jan 1968

Wheat Weevil And The Farmer, Clee Francis Howard Jenkins, G. D. Rimes

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

INSECT pests have been taking toll of mans' crops and herds since very early times and despite modern control techniques the annual loss is still very high.

It has been estimated that damage to stored grain alone may average 10 per cent, per year, or, in terms of the West Australian harvest, a loss by weevils of about twice the capacity of the large Midland Junction bin.


The Changing Fertiliser Industry, Edgar Noel Fitzpatrick Jan 1968

The Changing Fertiliser Industry, Edgar Noel Fitzpatrick

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

Background to current developments in the Australian fertiliser industry.

FOR many years superphosphate was the basic fertiliser used by most farmers in Western Australia.

During the 1950's some farmers began to use sulphate of ammonia, and recently urea and anhydrous ammonia have become important.


Sources Of Nitrogen For Cereals : Their Characteristics And Costs, M G. Mason Jan 1968

Sources Of Nitrogen For Cereals : Their Characteristics And Costs, M G. Mason

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

Generally similar results may be expected from all the sources of nitrogen available for cereal growing.

The unit nitrogen price and the convenience of use of each fertiliser in the particular situation should be taken into account in deciding which fertiliser to use.

THE first point to consider when deciding which nitrogen fertiliser to use for wheat growing is the effectiveness of the nitrogen source in increasing crop yield. Second, the cost per unit of nitrogen must be considered.

The convenience of using a particular source in a particular situation is also important and greater convenience may offset some cost …


Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture Jan 1968

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Rivers flowing to the Gulf of Carpentaria and the Timor Sea have been estimated by hydrologists to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes which, together, comprise the highly settled agricultural areas of South Eastern Australia.

In 1945, the North Australian Development Committee recommended research in the Ord-Victoria rivers region as a first step toward ultimate agricultural development of this Northern potential and, in 1946, the Kim- berley Research Station commenced operations under the joint control of the Commonwealth Scientific and Industrial Research Organization and the Western Australian Department …

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.


Drilled Versus Topdressed Superphosphate For Cereal Production, A Loutit, P. Stallwood, W. J. Cox Jan 1968

Drilled Versus Topdressed Superphosphate For Cereal Production, A Loutit, P. Stallwood, W. J. Cox

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

CEREAL growers in Australia usually use a drill or combine to apply their seed and superphosphate in one operation.

However, during the last few years, there has been a rapid increase in the amount of super broadcast bafore seeding.

Which Cereal Gives The Best Return?, H M. Fisher Jan 1967

Which Cereal Gives The Best Return?, H M. Fisher

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

IN 1966 farmers in the cereal areas of Western Australia sowed approximately 6.5 million acres of wheat, 1.2 million acres of oats, and 0.4 million acres of barley (mainly six-row).

The extent to which these cereals were grown in the various statistical divisions of the State, together with the average yields is summarised in the Table below.


Varieties And Time Of Sowing, H M. Fisher Jan 1967

Varieties And Time Of Sowing, H M. Fisher

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

THE extent to which seasonal conditions favour the various stages of plant development has a marked effect on cereal yields. Because varieties differ in their development they react in different ways to a particular seasonal pattern.
