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.

A combination of field, field enclosure, and germination chamber studies was used to evaluate the effects of methiocarb [3,5-dimethyl-4-(methylthio)phenol methylcarbamate] and thiram (tetramethylthiuram disulfide) repellent seed treatments on early corn performance. The thiram treatments used (0.08, 0.4,0.8,0.5,1.25, and 2.5% active ingredient by corn seed weight) had negligible effects on germination/emergence time or on com plant heights. The thiram treatments never reduced stand counts in comparison to controls, but apparently increased stand counts in some trials, particularly under wet conditions. The methiocarb treatments evaluated (0.5, 1.25, 2.5, and 5.0% active ingredient by corn seed weight) had only occasional effects on early …
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. …
Variation In Wheat Protein Content : The Effect Of Environment, G B. Crosbie, Harry Fisher
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.
