Evaluation Of Annual And Short Term Rotation Ryegrasses., Tony Albertsen
Experimental Summaries - Plant Research
The increasing range of annual and short term rotation ryegrasses have been evaluated in the high rainfall regions of the South West since 1986. To date promising later maturing cultivars such as Concord (in particular), Progrow, Aristocrat have consistently outyielded the standard early maturing cultivar Wimmera during the early winter period and in spring. These later maturing varieties have the potential to more fully utilise the whole of the growing season and to be conserved as hay during drier spring weather, whilst still retaining digestibility, protein and metabolisable energy. Viable seed production for self regeneration from later cut hay pastures …

Persistence of AMV in annual medic swards.
In 1990, the fourth year of this trial, although the medic plants were numerous the burr medic swards at Avondale grew poorly and weeds were widespread in the plots, especially long storkbill, flatweed and grasses. Poor growth was due to nodulation failure caused by low soil pH (5.3 in water). Hardly any medic plants were left in the Zodiac medic plot at Avondale while a few remained at Mt. Barker.

Grass and broad leaved weed control in direct sown crops.
Location: Chapman Valley Research Station.
The low rate of sprayseed with diuron was not as effective on the grasses. It may indicate some antagonism within the mix as the same rate of sprayseed with metribuzin did not cause any drop in grass control. The addition of 2, 4-D amine may have boosted the mixes activity on capeweed as the sprayseed metribuzin mix was not very good on capeweed.

Waterlogging : How It Reduces Plant Growth And How Plants Can Overcome Its Effects, Tim Setter, Bob Belford
Waterlogging : How It Reduces Plant Growth And How Plants Can Overcome Its Effects, Tim Setter, Bob Belford
Journal of the Department of Agriculture, Western Australia, Series 4
Lack of oxygen is the major cause of limited plant growth in waterlogged soils. When soils become waterlogged less gas diffuses to and from the roots through the soil pores; there are changes in concentrations of mineral elements in soil solutions; and toxic products of roots and soil microorganisms begin to accumulate. These changes adversely affect germination, growth and development of plants.
Plant Growth And Survival In Saline, Waterlogged Soils, Ed Barrett-Lennard, Neil Davidson, Richard Galloway
Plant Growth And Survival In Saline, Waterlogged Soils, Ed Barrett-Lennard, Neil Davidson, Richard Galloway
Journal of the Department of Agriculture, Western Australia, Series 4
Waterlogged soils in Western Australia are often salt-affected. Recent research has shown that the interaction between waterlogging and salinity has a far greater adverse effect on plant groivth and survival than either of these two factors individually. The consequences of the combined effects of salt and waterlogging for most plant species are increased salt uptake, reduced growth, chlorosis (yellowing of leaves), defoliation, and death. Salt sensitive agricultural species (nonhalophytes) are more severely affected by this interaction than salt tolerant species (halophytes).

Economics Of Interceptor Drains : A Case Study, Andrew Bathgate, Ian Evans
Journal of the Department of Agriculture, Western Australia, Series 4
This case study determines the most likely rate of return to capital invested in constructing seepage interceptor drains to reduce the effect of waterlogging on crop and pasture yields. The analysis of a farm in the Denbarker region, west of Albany, determined what increases were needed in pasture growth to justify the cost of constructing drains across four adjacent paddocks. The benefits of changing rotations to include lupins were also determined, as growing lupins was unprofitable before the construction of drains.

Mechanisms controlling development in barley.
Location: Melijinup Field Station.
A range of barley varieties have been assessed for their level of adaptation to a range of sowing dates across the cereal growing region of W.A. This study aims to determine the mechanisms controlling development in cultivars which represent the range of development responses available. The relative importance of photoperiod and vernalisation response and inherent earliness will be determined for each variety.

Resource management technical reports
Legume herbage mass was maximized after two or three years application of 50 kg/ha double superphosphate for both Verano and Fitzroy on Red earth soils and for Fitzroy on Yellow lateritic soils. There was increased production of Verano up to the maximum fertilizer level. Both varieties responded in the second year to residual P following application in the first year but there were no responses in subsequent years.

Resource management technical reports
A study involving the documentation of the extent and floristic composition of patches of native vegetation left uncleared by agricultural development is described. Floristic regions were defined in the study area by detailed analysis of the floristic data. The concentration of the major conservation reserves in only a few of these regions left the floristic variation of most of these regions poorly represented conservation reserves. About 13 percent of the private property remains uncleared.

Integrated Control Of Soil Insect Pests Of Potatoes, Stewart Learmonth, John Matthiesson
Journal of the Department of Agriculture, Western Australia, Series 4
One of the more difficult aspects of growing potatoes in Western Australia is controlling soil insect pests. These pests have become more troublesome because the highly effective and persistent organochlorine insecticides previously used to control the main soil pests, African black beetle and whitefringed weevil, were deregistered for agricultural use in 1987. Entomologists from the Department of Agriculture and CSIRO in Western Australia are collaborating to develop new management strategies for these pests that rely less on the use of chemical insecticides

The long-term fertility and stability of the yellow, grey and white sands which make up 60% of the northern wheatbelt soils can only be safeguarded through strict adherence to conservation cropping practices: notably, direct drilling of both cereal and lupin crops.
