The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard

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

Harvest losses represent a significant reduction in lupin production and farm productivity.

Since 1984, the Department's Farm Machinery Research and Liaison Unit at the Dryland Research Institute has studied the lupin harvesting operation to improve its mechanical efficiency. An experimental and a prototype harvesting front were built and tested in the field. Guidlines for efficient lupin harvesting were produced, and commercial modifications developed.

Erosion Potential Of Phomopsis-Resistant Lupins, D J. Carter, Paul Findlater

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

During lupin harvesting, up to 20 per cent of the grain remains on the ground. This non-harvested or pilt grain is a valuable feed for sheep during early summer because the pods, leaf and stem generally provide little nutrient in the stubnbles. In addition, the more efficient the weed control, the less valuable are the stubbles.

The disease lupinosis caused by Phomopsis leptostromiformis restricts the amount of grazing from the lupin stubbles, and hence the risk of wind-erosion of stubble paddocks.

However, the introduction of lupin varieties moderately resistant to Phomopsis and with reduced potential to cause lupinosis means that …

Water Erosion On Vegetable Growing Land In South Western Australia, D J. Mcfarlane, N D. Delroy, H V. Gratte, J P. Middlemas, A M E Van Vreeswyk, I Mckissock

Resource management technical reports

The most serious erosion was found to be occurring in the Donnybrook area due to a combination of erosive winter rainfall, steep slopes and erodible soils. The most serious erosion was found to occur when storm runoff entered the vegetable plots from above, providing a transporting medium for the cultivated soil. A predictive model of erosion showed that soil texture, furrow slope, plot length, rainfall erosivity and canopy cover were significant factors affecting soil loss.

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.
