Trial 89AB12
Great Southern Agricultural Institute - Paddock B15
This trial was of similar design to the single row evaluation, except four replications and pesticide treatments were also included.
However the trial had to be abandoned due to severe phytotoxic responses seen in the medics due to repeated spraying of 'Lorsban' (used at recommended rates).
Intended to repeat this work in 1990, bulk seed where possible and to eventually assess these lines, under such conditions, in large plots.

Pasture Deterioration Trial, J. W. Bowden, R. J. Lunt
Experimental Summaries - Plant Research
Trial 89NA61
Location: Duranillin
In this site we would expect a very large response (40 to 50% ) to phosphorus.
History:
The site was chosen because of the patchy and poor pasture production. The poor areas tend to have more suckling clover than the good areas. The pasture was legume dominant.
Treatments were applied on April 16, 1989.

Location: Dumbleyung.
Current recommendations for pasture species in the medium rainfall zone has not included species mixtures for paddocks with varying soil types. These trials (three in total) are designed to test the hypothesis that legume species mixtures are more productive and persistent in the long term than monocultures, across three soil types and three different cropping/pasture rotations (continuous pasture, 1 year pasture : 1 year crop rotation, 2 years pasture : 1 year crop rotation).

Finishing Kimberley Cattle In The South-West, Brian L. Mcintyre, Bill Ryan, Neville Macintyre
Finishing Kimberley Cattle In The South-West, Brian L. Mcintyre, Bill Ryan, Neville Macintyre
Journal of the Department of Agriculture, Western Australia, Series 4
The idea of integrating the Kimberley cattle industry with that in the south-west of Western Australia is no new, but until recently it had not been critically evaluated.
Over the past eight years the Department of Agriculture's Beef Cattle Branch has been assessing the performance of Kimberley cattle transported south for finishing in the agricultural areas.
This research has show that Kimberley weaners can be finished in the south, and that under the present (December 1988) economic conditions it is more profitable than running breeding cattle in the south-west and comparable with fattening store steers.
The Effect On Farm Profit Of Conserving Stubble To Prevent Wind Erosion, A D. Bathgate
The Effect On Farm Profit Of Conserving Stubble To Prevent Wind Erosion, A D. Bathgate
Journal of the Department of Agriculture, Western Australia, Series 4
Over-grazing of stubbles is a major cause of winf erosion on WesternAustralian farms. Stubble contributes to the 'roughness' of the paddock; as the roughness is reduced, the risk of winf erosion is increased.
The risk of lupinosis in sheep has previously reduced the likelihood of lupin stubble being over grazed, but the development of Gungurru, a phomopsis-resistent variety of lupin, has increased the potential for over-grazing and hence the probability of wind erosion.
This article describes the economic benefit (or cost) of conserving stubble at the conservation standards.
Planning For Horticultural Expansion On The Swan Coastal Plain, P Coghlan, Geoff Moore, Jim Dixon
Planning For Horticultural Expansion On The Swan Coastal Plain, P Coghlan, Geoff Moore, Jim Dixon
Journal of the Department of Agriculture, Western Australia, Series 4
Horticulture is an intensive, high value form of agriculture highly dependant on the availability of good water supplies for the year-round production of fresh produce. Production increase in Western Australia and the encouragement and development of export markets has caused rapid expansion if the industry in recent years.
Expansion is expected to continue, placing severe pressure on available water supplies and suitable land close to markets. At present' 90 per cent of the Stase's horticultural land is on the Swan Coastal Plain and minor selected hills areas around Perth.
