Toward Better Minimum Tillage For South-Coastal Sandplain Soils, W L. Crabtree
Toward Better Minimum Tillage For South-Coastal Sandplain Soils, W L. Crabtree
Resource management technical reports
Seventeen farmers compared their conventional cropping practices with some form of minimum tillage cropping. The minimum tilled crops yielded 21 percent less grain than the conventionally sown crops. The reasons for these decreased yields were in most cases related to inexperienced management. The minimum tilled treatments usually had very poor weed kill strategies which often resulted in large weeds at sowing, very cloddy seed-beds, and numerous insects in the young crops.

Coping With Brown Spot And Root Rots Of Lupins, Mark Sweetingham
Coping With Brown Spot And Root Rots Of Lupins, Mark Sweetingham
Journal of the Department of Agriculture, Western Australia, Series 4
There is increasing concern that brown spot and root diseases may limit the long term viability of lupin cultivation in close rotations in the agricultural areas of Western Australia. Research has found several useful strategies to reduce the impact of brown spot and Pleiochaeta root rot so that losses can be kept to a minimum. Rhizoctonia has proved more difficult to combat. Although less widespread than Pleiochaeta, it has caused severe losses and appears to be increasing in incidence, particularly in the northern wheatbelt. Research has vastly expanded our knowledge of the strains of Rhizoctonia present in our soils and …

Cucumber Mosaic virus in lupins.
A testing service for lupin growers was provided by the Seed Testing Station. The level of CMV in seed was determined in a 1000 seed sample using the ELISA (Enzyme Linked Immunosorbent Assay) technique developed by Dr. R.C. Jones.To speed up processing of samples levels greater than 1.2% were not determined - to do so would have required repeating the test at a different level of grouping. Growers were charged $114 per sample tested. The service was advertised as being available for samples received up until 28 February.
