Barley Breeding Update, P A. Portmann

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

Barley production in Western Australia has increased over the past few years, peaking at 1.42 million tonnes in 1984. The European Economic Community, however, has flooded world markets for barley and over half of ourbarley was sold for feed to Saudi Arabia last year. Current prices therefore have declined as has the total area sown to barley in this State.

Despite this, the potential to increase barley yields is most promising. The Department of Agriculture has cross-bred lines in advanced stages of field testing which could increase yield by 10 per cent across the agricultural areas.

Experiments were set up to screen a range of herbicides which might give improved control of Anguina agrostis over the currently recommended paraquat. Two experiments examined Roundup, Fusilade and Sertin at two rates and two experiments screened eight herbicides at five rates from two x "label recommendation" to 0. 99 x Standard treatment was paraquat at 550 ml. Plots were 3 m x 30 m in the first two experiments and 3 x 5 m (per dilution) in the second. The herbicides were applied on 4/9, 17/9, 24/9, 1/10 and 9/10 (Zadoks stages 32 - 58).

Skeleton Weed : How Serious A Threat In Western Australia?, F D. Panetta, J. Dodd

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

Skeleton weed is probably the most serious weed ever to threaten the Australian wheat industry. It interferes with wheat cropping at two stages: through competition with the growing crop, particularly for nitrogen and water during the crop's development: and later through the production of a tall, wiry flowering stem which tangles in harvesting machinery and can make harvesting difficult, if not impossible.

The weed is a major problem in eastern Australia although a combination of cultural, chemical and biological control programmes is helping to reduce its impact.

In Western Australia, skeleton weed is being contained mainly by eradication efforts. Weed …

The 1984 experimental programme was a continuation of that started in 1981. The programme was aimed at evaluating the major herbicides in current use for cereals as well as new herbicides against the recommended varieties at three main sites, these being Wongan Hills, Merredin and Mt Barker. In addition Stage 4 breeding lines were evaluated against the same herbicides but only at Wongan Hills. The herbicides used and their rates and time of application are presented in Table 1. Herbicides were applied at both the recommended and twice the recommended rates of application, except in the breeding line trial where …

These were grown on three contrasting soil types, a red-brown earth, a sandy loam over clay and a deep loamy sand; all soils occurring within close proximity to each other. Detailed measurements were made of meteorological conditions, dry matter production, leaf area, root growth, soil water profiles, light interception and plant …
