Breeding Wheat Varieties For Acid Soils, I R. Barclay
Journal of the Department of Agriculture, Western Australia, Series 4
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.

Crop Variety Testing And Recommendations, H M. Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
From 1984 onwards, the Department of Agriculture's crop variety recommendations for Western Australia will be set out in a new format directly related to the 18 variety testing areas into which the South-West has been divided. These divisions should enable growers to more readily identify the recommendations which apply to their area. In addition, yield data on the varieties are provided for each area.
The recommendations are the culmination of a lenghty process of breeding, selection and testing of crop varieties. This article gives the background to the tests and how the results are used as the basis for the …

The Stripe Rust Threat, B R. Whan, T. N. Khan
Journal of the Department of Agriculture, Western Australia, Series 4
The wheat disease stripe rust caused crop losses estimated at $20 million in New South Wales during an epidemis in 983. Economic crop losses were reported in neighbouring States and as far westas Ceduna in South Australia. In some States large areas were sprayed with fungacide at considerable cost to control disease spread.
Wheat stripe rust has not been found in Western Australia yet, but all current evidence indicates that it will eventually reach this State.When it does, it has the potential to cause considerable crop losses every year, unlike the spasmodic losses from stem rust, and it will greatly …
Molybdenum Deficiency In The Wheatbelt, M M. Riley
Molybdenum Deficiency In The Wheatbelt, M M. Riley
Journal of the Department of Agriculture, Western Australia, Series 4
The trace element molybdenum is needed in very small amounts in nitrogen metabolisms of crops and pastures. One of the projects that started as a result of the overall soil acidity research programme was the examination of molybdenum deficiency on acid soils throughout the South-West of Western Australia.
