Field Peas In The Wheatbelt, R J. French

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

Plantings of lupins in the Western Australian wheatbelt increased rapidly in the late 1970s and early 980s as improved varieties became available and farmers realised the benefits to be gained from growing grain legumes. Grain legumes are useful not simply as alternative cash crops. They provide 'fixed' atmospheric nitrogewn to following cereal crops and act as a cleaning crop to break cereal disease cycles. They are also valuable sheep feed.

In 1975, throughout the wheatbelt, the Department of Agriculture began a comparison of several alternative legumes. The crops included field peas, faba beans, chickpeas, lentills and various vetches. Field peas …

Peanuts In The Ord, D L. Mcneil, D. W. Bennett

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

The peanut industry on the Ord River Irrigation Area is expected to gross about $1.9 million at the end of the decade, a tidy return for an industry that only started truly commercial plantings some six yesrs ago.

At present the Ord River Irrigation Area produces about 2.5 per cent of Australia's total production, but it hopes to increase this to 7 per cent. High yields and plantings on non-staining soils make peanuts one of the most succesful crops grown on the Ord.

Grazing And Management Of Saltland Shrubs, C V. Malcolm, J. E. Pol

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

areas of bare saltland on farms need not be unproductive etesores. Many Western Australian farmers are now successfully growing salt-tolerant or halophytic shrubs such as bluebush (Maireana brevifolia), saltbushes (Atriplex spp.) and samphires (Halosarcia spp.) on these areas.

Department of agriculture trials and farmers' experience indicate that if saltland is planted with recommended shrubs, it can provide two months' valuable grazing for sheep during autumn and early winter, a time when paddock feed is scarce. Research by the Department has also identified a range of salt-tolerant shrubs suited to the various types of saltland.

Laser Levelling Land For Flood Irrigation, M D. Green, J. P. Middlemas

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

Since the introduction of laser levelling to Western Australia's South-West irrigation area five years ago, many farmers have benefited from this new and precise method of land-forming.

The use of lasser controlled earthmoving equipment to redevelop irrigated paddocks has led to improved irrigation efficiency and drainage. Less water is used for each irrigation, water is applied more evenly and less labour is needed. many older, grass-dominated paddocks have been reseeded to improve pasture species.

Algal Growth And The Phosphorus Cycle, Arthur J. Mccomb, K. S. Hamel, A. L. Huber, D. K. Kidby, R. J. Lukatelich

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

Larger algae and microscopic phytoplankton foul the waters of the Peel-Harvey estuarine system, upsetting the fishery and polluting the beaches.

These aquatic plants grow in response to phosphorus runoff from drainage, trapping phosphorus in the estuary and using it in their growth. When they die this phosphorus remains in the system to be recycled for further plant growth.

Algal pollution in the estuary can be lessened by reducing the amount of phosphorus entering the system, increasing phosphorus losses to the ocean, or in some way blocking the trapping and recycling processes.

Alternative Pasture Species For Deep Sands, D A. Nicholas

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

Although the climate of the swan coastal plain between Perth and Bunbury is suitable for growing a range of pasture species, some soil types greatly limit this range.

Pasture species commonly grown in the South-West, such as subteranean clover and annual ryegrass, can only be grown successfully on the better soils of the coastal plain - the loams, yellow sands and Joel sands. On the freely drained, deep, infertile Gavin sands such species rarely persist because of the soil's poor water holding capacity, and its water repellency and its poor ability to retain nutrients.

Research On Declared Plants And Other Weeds, G. A. Pearce

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

Knowledge about weeds is necessary to assess their significance, devise control measures and to select those which are to be declared for the purposes of the Agricultural and Related Resources Protection Act.

Once a plant has been declared in Western Australia, all landowners must control and prevent its spread to new areas and work towards eradicating known infestations. The Act also declares plants which are prohibited from entering the State.

It is becoming more and more important to provide specific reasons for the declaration of a weed and its placement in a certain category. Such decisions require appropriate action to …

Annean Station Management Plan, A A. Mitchell

Resource management technical reports

Annean Station's carrying capacity has been estimated at 8,340 sheep on its 168,539 hectares. The halophyte pastures of Carnegie Land System were in good condition while those of Mileura Land System were in poor condition. The wandarrie pasture of the Belele Land System was in fair to poor condition. This system comnprises 34 per cent of Annean's area and is estimated as capable of presently carrying 2,900 stock.

The Place For Annual Brome Grass, G W. Anderson

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

Grasses in the anual pastures of southern Australia are particularly important early in the growing season.

The main grass sown, has been annual rygrass, but concerns are emerging with 'annual ryegrass toxicity' and and 'in crop' competition.

This work looks at the role of annual brome grass in pastures.

Erosion Risks With High Stocking Rates At Kojonup Trial, Department Of Agriculture, Western Australia

A pasture grazing trial at Kojonup dramatically illustrated the effects of Cyclone Alby. Severe erosion was evident on the heavily stocked plots while the more lightly stocked plots showed little damage.

Serradella : A Pasture Legume For Sandy Soils, John Sylvester Gladstones, N. R. Mckeown

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

French serradella grows well on many of the sandy soils along the west coast where other species such as sub clover often fail, and produces excellent feed both when green and in the dry state.

Establishment is easy because of its soft seedednedd. However the same characteristic, together with its erect growth habit, means that persistence under grazing has been poor.

This paper looks at work being done to understand the requirements to maximise results from serradella and develop better varieties.

Native Plants : Water Savers In The Garden, K S. Cole

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

The climate of Western Australia may be one of the best in the world for people but it is a difficult one for many of our imported, and common garden plants. as a consequence, some 70 per cent of our summer water usage is for gardens and lawns.

This is not the sort of statistic that we should accept easily or happily.

There is a solution to this problem: a new approach to home gardening is required.

The new garden is based on W. A.'s own colourful native plants, which are adapted to mild winters, hot dey summers and poor …

Progress In The Nursery Industry, W J. Heggers

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

The demand for ornamental plants in Western Australia is sat an unprecedented level, making the nursery industry a relatively prosperous branch of horticulture.

One reason for the continued demand for nursery lines is probably that people are concerned about the environment - "green survival", as it is often refered to in promotional literature.

In rural areas, farmers are becoming increasingly aware of the value of planting windbreaks, shade and ornamental trees, while mining companies and the Forests Department are actively engaged in re-afforestation.

As a result the nursery industry is in a healthy situation and can continue to develop in …

Water Economy For Lawns And Gardens, K S. Cole

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

Much of the summer water consumption occurs because it is widely believed that heavy summer watering is necessary. Householders often mistakenly water heavily to keep their gardens green and growing. Many may not realise that gardens can be kept vigorous and healthy with much less water than is commonly applied.

Some Concepts In Rangeland Management, R B. Hacker

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

The arid and semi-arid zones of Australia occupy about 75 per cent of the land mass. The pastoral industries are located within these zones and, although productivity per unit area is low, the region nevertheless constitutes one of the nation's valuable renewable resources.

If properly managed, such a resource may be maintained as a productive asset indefinitely.

Samphire For Waterlogged Salt Land, C V. Malcolm, G. J. Cooper

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

For non-waterlogged and mildly waterlogged salt land a number of salt-tolerant shrubs may be used for forage production.

Areas which are highly saline and regularly waterlogged are not suited to these shrubs. However, during trials with shrub species, samphires (Arthrocnemum spp.) were found to volunteer and grow well on these sites.

Research into the use of samphires has shown that it is possible to harvest seed and obtain a seed sample suitable for sowing through a drill. Established samphire stands provide useful grazing in many parts of the Western Australian wheatbelt.

Forage Production From Shrubs On Saline Land, C V. Malcolm

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

In the first volume of the Journal of the Department of Agriculture in the year 1900, the results of experiments at Tulare Experiment Station in California on the growing of Australian saltbushes are reported.

Seed was first sent from Australia by Baron von Mueller in June, 1881. Three species of saltbush (A. semibaccata, A. numularia and A. vesicaria) are all reported to have grown well.

Although C. A. Gardner in 1929 suggested the growing of saltbushes for forage, the earliest and clearest recommendations are those of Teakle and Burvill in 1945.

Early research tended to concentrate mainly on the possibility …

Nitrogen For Pastures, Department Of Agriculture, Western Australia

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

The use of nitrogen (N) fertilisers on cereals has long been recognised and accepted as an economic farm practice. It is only more recently that the use of fertiliser nitrogen has been considered for pasture and fodder production, mainly on wholemilk and butterfat farms in the South-West. The high quality feed produced may be substituted for concentrates or conserved fodder. Large increases in seasonal production have been reported.

Because nitrogen fertiliser is expensive, has a short-term effect, and can affect the clover content of pastures, a series of field experiments were conducted in 1973 to examine the role of nitrogen …

Potassium For Pastures, Walter Jacob Cox

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