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.

Progress In Research On Noxious Weeds, Geoffrey A. Pearce

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

RESEARCH on noxious weeds has enabled the development of many practical methods for the control of these weeds.

Where the recommended treatments have been accepted by farmers, large scale operations have reduced the areas infested and stopped spread into new paddocks.

Establishing Pastures Under Wheat Crops, M L. Poole, J. W. Gartrell, D. A. N. Nicholas

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

RECENT surveys indicate that in the medium and high rainfall cereal and sheep areas as much as half the new pasture sown is sown with a crop.

In the drier wheatbelt areas the figure is 20 to 30 per cent.

The Making Of A New Pasture Variety, Department Of Agriculture, Western Australia

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

FARMERS who attend field days at Department of Agriculture research stations are reasonably familiar with the procedure for producing a new cereal variety. It involves a painstaking and tedious process of crossing, followed by many years of segregation, selection and testing for yield, disease resistance, and other characters.

Although there are many pitfalls, the procedure for the creation of a new cereal variety is at least fairly well systematised.

Until recently the making of a new pasture variety was far from a systematic undertaking.

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.

Recommended Cereal Varieties : 1969, H M. Fisher, J. T. Reeves, J. A. Parish

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

Cereal varieties widely recommended for growing in 1969 are Gamenya and Falcon wheats, Dampier and Beecher barleys and Swan oats.

Other varieties include the new wheat Darkan, which is recommended only for the higher rainfall areas, the rust resistant wheats Mengavi and Gamut, and Irwin oats for late sowing in northeastern districts.

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.

Weed Control In Linseed, J G. Paterson

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

In 1967, almost 7,000 acres of linseed were planted in Western Australia. The area increased to more than 25,000 acres in 1968 and it is expected that some 40,000 to 50,000 acres will be planted in 1969.

FOR MANY years linseed has been a comparatively unimportant crop, recently been highlighted both as a "cleaning" and as a "cash" crop. Its value has

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.

The Control Of Weeds In Cereals, Geoffrey A. Pearce

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

PRACTICALLY all broadleaved weeds found in cereals can now be killed with herbicides and with most, the farmer has a choice of chemicals.

Two more new products are now available and these have several advantages over other herbicides.

Chemical Ploughing, Geoffrey A. Pearce

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

PROGRESS in the field of chemical weed control has been spectacular in recent years. One field that is attracting interest is the idea of replacing cultivation with chemical sprays.

Wren Wheat Unimpressive In West Australian Trials, Department Of Agriculture, Western Australia

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

WREN WHEAT, the subject of current controversy in the Eastern States, has been tested in trials in Western Australia and the results have indicated that it is not likely to yield well in this State.

Lupins In Western Australia. 2. Cultivation Methods, John Sylvester Gladstones

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

While lupins are by and large plants of lighter and less fertile soils, important differences exist among them in their soil preferences.

There may also be some differences in climatic requirements. Present knowledge of these differences is summarized in the Table below.

The Long Term Effects Of Frequent Cropping, Stanley Thomas Smith

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

AGRICULTURALLY speaking, few Western Australian soils are more than 50 years old. We have the responsibility of preserving them for farming—not for one man's lifetime, but for centuries.

The aim of this article is to demonstrate that cropping and cultural practices do have some effects on the soil, and that these effects should be considered when choosing a farm rotation.

Fertility Build Up Under Northern Wheatbelt Pastures, M L. Poole

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

Experiments on two farmers' properties demonstrated that legume pastures increase the fertility of northern wheatbelt soils.

Crops on legume pastures had higher yields than crops on volunteer pasture.

The experiments also indicated the most productive legume species for each situation and demonstrated that nitrogen added by legumes has a residual effect in the soil.

Pasture Seed Production In Western Australia, B J. Quinlivan

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

Pasture seed production in Western Australia is an industry with a somewhat turbulent past. Booms and slumps have been the rule rather than the exception.

However, during the past few years there has been some degree of "stability"—if not in price, at least in terms of total production.

How Important Are Wild Oats?, J G. Paterson

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

WILD OATS tend to grow best on heavy, fertile land. They can be a particular problem in wheat crops where soils of this type predominate.

Trials have shown that wild oat competition is more important in a high yielding wheat crop than it is in a low yielding one. The extent of this competition is described in this article.

The Certified Strains Of Subterranean Clover : Their Origin, Potential Use And Identification, B J. Quinlivan, C. M. Francis, M. L. Poole

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

SUBTERRANEAN CLOVER originated in the countries surrounding the Mediterranean Sea and in parts of Western Europe.

Therefore it is not surprising that it grows well in the agricultural districts of Western Australia, for these regions have a typically Mediterranean climate with cool wet winters and hot dry summers.

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.

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.

New Varieties Top 1967 Yield Tests, H M. Fisher

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

LARGE gains can result from using improved cereal varieties and in recent years activity in breeding varieties adapted to local conditions has increased.

The varieties available and their suitability for different areas and conditions need constant review.

Snail Investigations : A Progress Report, G D. Rimes

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

Experimental baits and sprays have given promising control of snails in cereals and pastures in the Geraldton-Dongara districts.

The problem of harvesting infested wheat crops has been overcome by attaching a specially designed rake in front of the header ccmb to remove snails from the plants.

A Descriptive Model Of The Sweet Corn And Pea Processing Industry Of Southern Minnesota, David P. Brennan

All Graduate Theses, Dissertations, and Other Capstone Projects

This research project was initiated to construct and test a model of the sweet corn and pea processing industry of Minnesota. The model is a composite abstract consisting of several basic theories of general application and several hypotheses which were formulated to consider the unique properties associated with sweet corn and pea processing. These are related to the agricultural and industrial factors which are inseparable parts of sweet corn and pea processing. Testing the model concerned the evaluation of the theories and hypotheses with regard to the real life situation. The basic concepts used in the model were refined and …

BUSSELL is a new high yielding 2-row barley variety named early in 1967.

An early maturing variety, with white grains of good quality, Bussell has short and extremely strong straw.

It has yielded more than any other variety under test in areas of Western Australia which receive more than 18 inches of annual rainfall.

It has yielded more than Prior in all areas.

Subterranean Clover Establishment In The Wheatbelt, M L. Poole

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

Care and attention to detail will greatly increase the chances of establishing good subterranean clover pastures in the wheatbelt.

PASTURE ESTABLISHMENT usually takes second place to cropping in the wheatbelt, with many farmers "bunging in a bit of clover" and hoping for the best. The worst often transpires, with either patchy stands or complete failure resulting.

Using "cheap" methods of establishment is a short-sighted approach and a waste of energy and resources.

Grasshoppers And Locusts In Western Australia, Clee Francis Howard Jenkins

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

GRASSHOPPERS and locusts are among the most ancient enemies of the farmer, for they figured prominently in Biblical times, and periodically throughout the ages have devastated crops in all parts of the world.

Legume Inoculants For 1967, W A. Shipton

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

PERIODIC changes are made in the strains of rhizobia released for the inoculation of various legume groups.

These changes are made when it is evident from experimental data that better strains of rhizobia are available, or that the old ones are no longer effective.

New strains of rhizobia may give improved nodulation of legume seedlings or increase dry matter yields.
