The Effect Of Soil Acidity On Barley, P J. Dolling, T. D. Haines
The Effect Of Soil Acidity On Barley, P J. Dolling, T. D. Haines
Experimental Summaries - Plant Research
Three liming experiments were established to confirm previous estimates of the critical soil acidity level for barley. Two experiments studying the effect of depth of incorporation on the effectiveness of lime, established in 1986, were continued in 1987.
The results from the three liming experiments established this year supported the conclusion that barley is affected by soil acidity at pH's around 4.2 and 4.3 (CaC12) and that depth of this acid layer is important.
Significant lime responses were obtained at the Katanning depth of lime incorporation site but conclusions can not be made because of possible mixing of …

Manipulation Of The Soil Seed Reserves Of Bromus Diandrus And B. Rigidus By Enhancing The Breakdown In Seed Dormancy., A H. Cheam
Experimental Summaries - Plant Research
Location: South Perth Field Plots
Previous studies on the seed bank of Bromus diandrus indicated that shallow burial of newly shed seeds enhanced the breakdown in seed dormancy over the summer period. To bury the Bromus seeds one practical approach is to introduce sheep into the paddock.
This study is a repeat of the previous work but included B. rigidus, another species of Bromus, that is commonly ground growing in association with B. diandrus.

The Demography Of Doublegee. Ecological Studies On Arum Lily., F. D. Panetta
Experimental Summaries - Plant Research
3.1 Growth of doublegees under summer irrigation. (87A40)
The weevil, Perapion antiquum is a potential biological control agent of doublegee. However, it exhibits large population crashes during the summer months in the summer-dry areas of the Western Caped of South Africa, where it is native. It has been suggested that one means of successfully establishing Perapion in Western Australia could be to maintain populations in 'oases' over the summer months. The aim of this experiment was to determine how readily doublegee could be maintained in a non-senescent phase under irrigated and shaded conditions.

Effect Of Different Chemical Treatments On Capeweed Control And Crop Yield., J. R. Peirce, B. J. Rayner
Effect Of Different Chemical Treatments On Capeweed Control And Crop Yield., J. R. Peirce, B. J. Rayner
Experimental Summaries - Plant Research
Trial 87WH60
Control of capweed was obtained using post-emergence in-crop herbicides. Good control was on most of the treatments applied before seeding.
Most products showed good ryegrass control are not usually effective, assume some other factor operating. Treatment usually associated with good ryegrass control have higher ryegrass densities than the treatments using herbicides with only broadleaved variety.
Although large reductions in density of silvergrass were obtained none was significantly better than the unsprayed. Some treatments particularly those favouring grass dominance allowed silvergrass density to build up.
Bromegrass appears to be very sensitive to competition from capeweed. Where there was high …
