Clover, Bluegreen Aphid And Red Legged Mite Screening, Medicago Murex Evaluation, D J. Gillespie
Experimental Summaries - Plant Research
Clover scorch: In spite of poor seasonal conditions, adequate levels of clover scorch developed in the test plots to readily identify susceptible clovers. Of the 333 introductions tested, 23% scored 3.0 or less indicating a high level of resistance. Bluegreen aphid screening: Two hundred and twenty four randomly selected subterranean clovers from all Western Mediterranean collections were tested for resistance to BGA in Nov/Dec of 1983. The susceptibility of annual legumes to Bluegreen aphid. Red legged earth mite screening: Results of two preliminary experiments to develop techniques for mass screening for RLEM resistance in subterranean clover were reported last year. …

84M5, 84M6, 84M7. Location: Merredin Research Station Merredin, Western Australia. Three experiments were conducted to measure the productivity and water use of alternative wheatbelt crop species on contrasting soil types in a dry mediterranean environment. Crop species investigated were wheat, barley, cereal rye, narrow leafed lupin and field pea. These were grown on three contrasting soil types, a red-brown earth, a sandy loam over clay and a deep loamy sand; all soils occurring within close proximity to each other. Detailed measurements were made of meteorological conditions, dry matter production, leaf area, root growth, soil water profiles, light interception and plant …

Soil Acidity And Legume Nodulation, J G. Howieson, M. A. Ewing
Journal of the Department of Agriculture, Western Australia, Series 4
Nitrogen is a basic constituent of protien and is essential to all forms of life. Many agricultural plants are legumes - a group of plants which, in co-operation with specialised soil bacteria, fix their own nitrogen from the air. When the legume dies, the organic matter breaks down anf the nitrogen becomes available to the following crops.
Soil acidity is a major factor limitimg the successful association between legumes and their beneficial soil bacteria in Western Australia.

Most soils of the high rainfall area of south-western Western Australia are naturally acis.
The most acid group of soils, the peaty sands. have been routinely limed before subterranean clover pastures were established since research in the 1950s showed that poor Rhizobium nodulation could be overcome with the application of about 2 tonnes per hectare of coastal limesand.

Wheat varieties with improved tolerance of acid soils cold increase yeilds be perhaps 20 per cent or more over a substantialarea ofWestern Australia's eastern wheatbelt.
Aluminium toxicity is probably the main cause of poor root growth and therefore reduced yields on these soils.
