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 …

Understanding Crop Growth On Duplex Soils., R. Belford, Miles Dracup, D. Tennant

Experimental Summaries - Plant Research

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.

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.
