Trial 88EB18
Location: East Beverley Research Station
Impeded early root growth.
Using aerial photography and crop growth data from previous seasons we identified areas on the site where crops grow well or poorly. One of the factors implicated in the poor growth areas is impeded early root growth (see Belford et al. and Tennant et at., 1990 Experimental Summaries, this section). Here we describe the problem and outline possible causes.

Trial 87A19, 87MT50
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.

Effect of depth and degree of soil disturbance on root and shoot growth of wheat on wind erosion prone sandy soil.
Location: East Chapman Research Station.
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. Work by R. Jarvis has shown a 10 - 15% yield advantage due to cultivation of sandplain soils, and data suggest that it is cultivation depth (degree of soil loosening) rather …
