Symptoms Of Nutrient Deficiencies In Rape, M G. Mason, J. W. Gertrell

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

Rape is a relatively new crop in Western Australia and this investigation was undertaken to produce visual symptoms of nutrient deficiencies so that they could be recorded and used for diagnosing deficiencies in the field. The appearance of mineral deficiency symptoms can vary considerably with growing conditions, so that symptoms produced in a glasshouse are only a guide to the probable symptoms in the field.

Bulletin No 3768 - Submitting Plants For Disease Identification, M D. Marcley

Bulletins - 3000 - 3999

THERE are several important points to remember when submitting plant material for disease identification by the Department of Agriculture's Plant Pathology Branch.

Firstly it is very important to collect a suitable sample because it is very difficult to determine the cause of a plant disease by looking at a completely dead plant. The sample should include the entire plant (before it is completely dead) including roots and soil. Then all the effects of the disease can be seen. For example leaf yellowing, dead areas of the stem, collar rot, root rot, eelworm damage, and disease of the water and food …

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.

Barley Staining, J A. Parish, G. B. Crosbie, A. G. P. Brown, P. A. Portmann

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

GRAIN discolouration or "staining" is a quality defect in W.A. barley which substantially reduces the marketable value oi the crop. It also causes heavy losses to individual growers whose grain is docked or rejected.

Rapeseed. 4. Grain Quality, G B. Crosbie, M. L. Poole

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

RAPESEED is capturing an increasing share of the world edible oilseed market.

It competes with other oilseeds such as soyabeans, peanuts, sunflower and safflower seed.

If Western Australia is to share in these markets it is essential that only high quality seed is produced.

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 Establishment In The Wheatbelt, M L. Poole

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

The value of legume based wheatbelt pastures is so great that considerable care is warranted during their establishment. Without such care patchy establishment or even complete failure is likely to occur.

IN THE WHEATBELT too many farmers still put less effort into their seeding of pasture species than their seeding of crops.

This may be because both compete for the farmer's time in the busy seeding period and it is the cereal crop which possesses the obvious cash value.

However, the total value of a good pasture has to be assessed over a period of several years because of its …

Linseed Production Survey : Esperance, 1968, R J. Guyton

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

A SURVEY conducted after the 1967 linseed season found that although most farmers understood the requirements of linseed growing there were several crop failures. These were associated with time of planting, soil type and insect control measures.

The Esperance district office of the Department of Agriculture conducted a second survey during December, 1968 and January, 1969

OVER ONE MILLION acres of oats are grown yearly in this State, making the crop next in importance to wheat.

Pathogenic organisms are responsible for considerable reductions in yield, yet losses can be minimized if control measures are taken.

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.

Deferred Grazing Improves Soft Spinifex Association, H Suijdendorp

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

THE Pastoral region in Western Australia where Triodia pungens (soft spinifex) makes up most of the vegetation, covers an area of about 17,000 square miles in the Forrest and De Grey pastoral areas.

On the deeper granitic sands in much of the region, plant associations revert to a pure stand of soft spinifex after about five or six years' grazing. It is common practice to burn at this stage, to encourage the re-establishment of other species and the production of palatable spinifex regrowth.

Lupins In Western Australia. 3. Cultivation Methods Continued, John Sylvester Gladstones

Long Term Rotation Trials, Ian Rowland

Experimental Summaries - Plant Research

The object of these trials is to attempt to determine the best rotation for each area or at least give some guidelines for recommendations as to the optimum rotation. Also to determine the effect of various pasture phases on the performance of the following crops and the number of crops required to utilise any accrued benefit from the pasture. In addition the trials on the Salmon Gums Research Station (68SG5) will attempt to compare cereal rotations on both volunteer and barrel medic pastures. It is also hoped to be able to get some estimate of grazing production from barrel medic …

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.

Barley Yellow Dwarf Virus In Western Australia, W A. Shipton

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

Cereal Eelworm : A New Disease Of Cereal Crops In The Geraldton Area, R J. Parkin, Olga M. Goss

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

CEREAL eelworm (Heterodera avenae) is a potentially serious disease of crops which was seen in the Geraldton area for the first time in the 1966-67 season.

It was first identified in this State at Beverley in 1958 and later near Northam in 1963.

The Geraldton region has been the only area found to be affected since.

The disease was identified on eight properties in 1966-67, and a further ten properties in 1967- 68. There are indications that many more properties could be affected in varying degrees.

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.
