Wesreo : A Blackleg Resistant Rapeseed, N N. Roy

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

A new rapeseed variety, Wesreo, has recently been released after an unusually rapid and successful breeding programme by the Department of Agriculture.

Wesreo has fairly good resistance to the disease blackleg, which virtually halted the expanding rapeseed industry in 1973.

How Efficient Are Seeding Operations : Kondinin Work Study, E J. Roberts, C. R. Lester, J. E. Young

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

The efficiency of machinery and labour during seeding operations was studied in 1977 by the Kondinin and Districts Farm Improvement Group and the Department of Agriculture. The aim was to find what influenced efficiency during cropping.

Time spent on activities during the working day was measured, and it was found that repairs, maintenance, meals and other incidental jobs considerably reduced the time spent driving the tractor.

Each farmer participating in the study was given the results of his own farm compared to the group, indicating tasks most needing improvement.

Bulletin No 3573 - Wheat Diseases In Western Australia, A. G. P. Brown, G. C. Mac Nish

Bulletins - 3000 - 3999

Diseases caused by pathogenic organisms can seriously affect the yield of wheat. Some diseases are comparatively rare whereas others occur over a large area of the wheatbelt year after year.

it is important to be able to identify diseases correctly so that the appropriate control measures can be applied, In the following article the diseases of wheat caused by pathogenic organisms are illustrated, with their symptoms described, and where possible, the control measures given.

Trials Indicate Best Lupin Seeding Rates, G H. Walton

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

Trials on the seeding rate of lupins have shown that for most crops, at least 80kg of seed per hectare gives best yields. However the yields varied considerably, and in higher yielding situations, lower seeding rates were better.

Seed yields of early maturing subterranean clovers. A brief description of weather conditions in 1977, site details and results of germination counts and growth ratings were included in the Summary Report for 1977. Drill-sown trials - Seed yields from the trials varied from good in the southern wheatbelt to very poor in the northern areas. Test samples were taken from trials 77GE32, 77GE40 and 77GE41 in the Pindar and Tardun districts, 77ME22 at Koorda and 77TS25 at Perenjori but the quantity of seed did not warrant yield assessment. Trial 77M022 at Gabalong was not sampled. Seed yields from the rest …
