Three New Late-Midseason Subterranean Clovers Released For High Rainfall Pastures, Phil Nichols, Donald Nicholas

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

Three new subterranean clovers - Denmark, Gou/bum and Leura - have been released in 1992 by the National Subterranean Clover Improvement Program. These subterranean clovers are black-seeded, have low oestrogen levels and improved disease resistance. Their release offers the potential for substantial improvements in pasture productivity in areas of southern Australia that have long growing seasons.

This article outlines some of the testing procedures and subsequent selection of these varieties and describes their characteristics and potential role in Western Australia.

Breeding Field Peas : Screening Pea Lines, G H. Walton

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

The early use of field peas in Western Australia was as a green manure crop or to feed stock be grazing the mature crop. Varieties which produced a large bulk of green material were sown. There was no control over insects or diseases.

In 1985, the Feseral Government recognised that to realize the potential of grain legumes grown throughout Australia, more research was needed.

One of the Grain Legume Research Council's (GLRC) priorities is species evaluation and variety improvement.

Since 1983, the Western Australian Department of Agriculture has screened advanced crossbred lines from the South Australian breeding programme for its …

Barley Breeding Update, P A. Portmann

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

Barley production in Western Australia has increased over the past few years, peaking at 1.42 million tonnes in 1984. The European Economic Community, however, has flooded world markets for barley and over half of ourbarley was sold for feed to Saudi Arabia last year. Current prices therefore have declined as has the total area sown to barley in this State.

Despite this, the potential to increase barley yields is most promising. The Department of Agriculture has cross-bred lines in advanced stages of field testing which could increase yield by 10 per cent across the agricultural areas.

In the longer term, …

Subterranean Clover In W.A. 1. The Current Situation, B J. Quinlivan, C. M. Francis

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

From small beginnings some 50 or more years ago subterranean clover has come to dominate the pasture scene in Western Australia. Of the 7 000 000 hectares of sown pasture all but some 500 000 are sown to subterranean clover. Further, it is estimated that there remains an area of similar size still to be sown, although in some instances these future sowings will be possible only if suitable varieties are available.

Clearing and pasture development within the various agricultural regions of the State took place, as a rule, within quite clearly defined time intervals and the varieties selected for …

Trikkala, A New Safe Clover For Wet Areas, C M. Francis

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

Trikkala is a new low oestrogen subterranean clover cultivar which has been released to seed producers this year. It should be available in quantity to farmers in 1977 and is recommended as an alternative to Yarloop for winter-wet situations.

Grain Crop Varieties For Western Australia, H M. Fisher

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

Recommendations for grain crop varieties grown in Western Australia are based on the results of field trials carried out each year by the Department of Agriculture at some 50 sites throughout the agricultural areas.

New varieties are tested directly against existing commercial varieties in large scale field trials for several years. Yield and quality results are analysed and market requirements are studied before recommendations are formulated.

This article gives information on the varieties of a range of crops now recommended for growing in Western Australia.

Breeding Better Rape And Lineseed For Western Australia, N N. Roy, J. Reeves

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

Rapeseed and linseed—the main oil seed crops grown in the south-west of Western Australia—have both been beset by problems which have limited farmers' interest in them.

Rapeseed was first grown commercially in 1970, when wheat quotas and low prices for other cereals forced farmers to seek alternative cash crops. The area sown to rapeseed increased rapidly, but disastrous outbreaks of the disease blackleg caused rapid decline, and little rapeseed is now sown.

Linseed has been grown in W.A. for more than 30 years. Linseed rust proved disastrous but was overcome by the introduction and breedbreeding of rust-resistant varieties. In recent …

A New Look At Sweet Lupins In Western Australia, C M. Francis, M. L. Poole, M. H. Chopping

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

BECAUSE they have a seed protein content of 30 to 45 per cent., sweet lupins are playing a growing role in animal feeding, particularly in the poultry industry. Their value as a protein supplement should ensure a continued local market as at current prices they are highly competitive with soya beans in cost per unit of protein.

Commercial Production Of Egg-Plant, James P. Fallon

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

The egg-plant or aubergine (Solarium melongena) is a sub-tropical plant which is not only very tender to frost and low temperature, but requires a long growing season.

Growing Barley For Grain In Western Australia : Varieties And Production Methods, H M. Fisher

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

BARLEY is an adaptable crop which can be grown successfully throughout the cereal areas of Western Australia. It is more suited to the wetter areas than wheat and tolerates the drier, shorter season of the eastern cereal districts better than oats.

Lupins In Western Australia. 1. Species And Varieties, John Sylvester Gladstones

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

First in a series of articles on the varieties, cultivation and uses of lupins in Western Australia.

Lupins are ideally suited to the climate and soils of many districts of Western Australia and their cultivation here dates from the early years of the century.

However, although there were some 500,000 acres of lupins growing in the State in 1968, their cultivation in recent years has been largely limited to infertile sandplain soils where other legumes usually fail.

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.

Papaw Varieties For Carnarvon, Michael Gregory Hawson, D. W. Thomas

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

Wheat Diseases In Western Australia, W A. Shipton, W. R. Tweedie, K. J. Locke

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

DISEASES caused by pathogenic organisms can seriously affect the yield of wheat. Some diseases are comparatively rare whereas others occur over a large area of the wheatbelt year after year.

Stem Rust Of Wheat, H L. Harvey

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

STEM RUST is one of the most serious diseases of wheat and is of world-wide importance.

Fortunately, widespread epidemics are rare in Western Australia because the general climatic conditions are usually unfavourable to the disease.

Nevertheless, localised outbreaks of stem rust are quite common on the Esperance Plains and around Geraldton where seasonal conditions are frequently mild and humid.

Recommended Wheat Varieties, 1965 : State Wheat Advisory Committee Recommendations For Wheat Varieties For 1965 Plantings, Department Of Agriculture, Western Australia

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

State Wheat Advisory Committee recommendations for wheat varieties for 1965 plantings.

THE wheat rust epidemic of 1963 has directed attention to resistance of varieties to this disease, new races of which have recently appeared in Western Australia.

However, last year was one of abnormal seasonal conditions, with late summer rains followed by a mild winter, and spring conditions which favoured rust.

Wheat Breeding And Variety Trials, 1963-64, J T. Reeves

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

A review of the wheat breeding and pedigree seed production by the Department of Agriculture.

Yields from the wheat variety trials at agricultural research stations during the 1963-64 season are presented and discussed.

The 1963-64 Wheat Stem Rust Epidemic, J T. Reeves

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

Comments on the 1963 epidemic and the current situation regarding rust races and resistant varieties in Western Australia.

THE 1963-64 harvest included 12 million bushels of undergrade wheat, representing 25 per cent, of the total harvest.

The average yield was reduced to only 11.3 bushels per acre. Although these adverse effects were due to a number of causes, the principal one was stem rust.

The economic loss due to this disease in the 1963-64 harvest probably exceeded £10 million.
