Trends In Wheat Protein/Yield Relationships, G B. Crosbie, Harry Fisher, Bryan Whan
Trends In Wheat Protein/Yield Relationships, G B. Crosbie, Harry Fisher, Bryan Whan
Journal of the Department of Agriculture, Western Australia, Series 4
The major concern of wheat breeders in WesternAustralia has been to increase grain yield while maintaining quality at an acceptable level. There has been no concious effort to select for protein content. It is of interrest, therefore, to compare the relationship between yield and protein of varieties which have been prominent in Western Australia at various times, to see what effects yield increases have had on protein content and the extent of any variation which might exist.

Variation In Wheat Protein Content : The Effect Of Environment, G B. Crosbie, Harry Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
Over the past 20 years, the average protein content of WesternAustralian wheat has ranged from 9.3 to 12.0 per cent, with a mean level of 10.4 per cent. At most grain receival points, in any one season, individual loads can often vary in protein content by as much as 5 per cent protein or more. Rainfall and soil fertility account for much of this variation.
The Potential For Skeleton Weed, John Dodd, F. D. Panetta
The Potential For Skeleton Weed, John Dodd, F. D. Panetta
Journal of the Department of Agriculture, Western Australia, Series 4
Since its introduction into Australia during the 900s skeleton weed has become one of the most economically significant weeds. Its presence in cereal crops in south-eastern Australia has caused suvere yield reductions and harvesting problems.
Skeleton weed was first found on a Western Australian farm in 963. Since then it has been the subject of an intensive eradication campaign organised by the Agricultural Protection Board and funded by an annual levy on wheat growers. Such campaigns, which rely mainly on volunteer searchers, do not exist in eastern Australia because the weed is so widespread it would be impossible to eradicate. …
Gypsum Use In The Wheatbelt, M R. Howell
Gypsum Use In The Wheatbelt, M R. Howell
Journal of the Department of Agriculture, Western Australia, Series 4
One of the limitations to crop productivity in the wheatbelt is the poor structure of heavy textured soils. Many years of clearing and cultivation have caused the loss of soil organic matter and breakdown of soil aggregates - particles of sand, silt and clay - in the surface layers. This has led to the development of unstable soils with poor physical properties.
Although loss of soil structure is a serious problem, it can be reversed by altering the tillage practices that caused the problem. This improvement in soil structure and return to productivity can be a slow process. However gypsum …
Wheat Payments And Protein Content, Department Of Agriculture, Western Australia
Wheat Payments And Protein Content, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
In recent years there has been increasing support from within the Australian wheat industry for the principal of wheat growers recieving payment for their grain according to market value.
Individual loads are now tested for quality characteristics such as hectolitre weight, unmillable material and moisture content.
At present, technology is not sufficiently advanced to enable rapid and accurate analysis of individual loads for all important quality factors.
A more practical system of quality assessment would be one based on allowances for various basic measures (such as hectolitre weight, unmillable material and moisture content), variety (to allow for genetic differences in …
Effect Of Agronomic Practices On Wheat Protein Levels, M G. Mason
Effect Of Agronomic Practices On Wheat Protein Levels, M G. Mason
Journal of the Department of Agriculture, Western Australia, Series 4
High grain protein levels are preferred for many end-uses of wheat. However, there has been little or no incentive for farmers to use practices which would increase protein levels, because wheat payments are made without a price differential for proteinlevel, except where wheat could qualify for the Australian Hard grade.
Broadacre Pest Control After Ddt, P J. Michael
Broadacre Pest Control After Ddt, P J. Michael
Journal of the Department of Agriculture, Western Australia, Series 4
DDT may no longer be applied to broadacre crops grown in Western Australia. It is being replaced by other more effective chemicals and with new methods of pest control. DDT was the most effective chemical for the control of several major broadacre pests in this State and farmers may well wonder why this change was necessary and how they will manage without DDT.
Increasing Protein Content Of Wheat By Breeding, B R. Whan, Graham Crosbie
Increasing Protein Content Of Wheat By Breeding, B R. Whan, Graham Crosbie
Journal of the Department of Agriculture, Western Australia, Series 4
The most efficient means of increasing protein content of WesternAustralian wheat is by breeding new varieties with higher inherent protein in their grain. But is this possible without sacrificing yeild or other desirable characteristics?
Field Peas In The Wheatbelt, R J. French
Field Peas In The Wheatbelt, R J. French
Journal of the Department of Agriculture, Western Australia, Series 4
Plantings of lupins in the Western Australian wheatbelt increased rapidly in the late 1970s and early 980s as improved varieties became available and farmers realised the benefits to be gained from growing grain legumes. Grain legumes are useful not simply as alternative cash crops. They provide 'fixed' atmospheric nitrogewn to following cereal crops and act as a cleaning crop to break cereal disease cycles. They are also valuable sheep feed.
In 1975, throughout the wheatbelt, the Department of Agriculture began a comparison of several alternative legumes. The crops included field peas, faba beans, chickpeas, lentills and various vetches. Field peas …
Peanuts In The Ord, D L. Mcneil, D. W. Bennett
Peanuts In The Ord, D L. Mcneil, D. W. Bennett
Journal of the Department of Agriculture, Western Australia, Series 4
The peanut industry on the Ord River Irrigation Area is expected to gross about $1.9 million at the end of the decade, a tidy return for an industry that only started truly commercial plantings some six yesrs ago.
At present the Ord River Irrigation Area produces about 2.5 per cent of Australia's total production, but it hopes to increase this to 7 per cent. High yields and plantings on non-staining soils make peanuts one of the most succesful crops grown on the Ord.
