Experimental Summaries - Plant Research
Trial 86KA64, 86KA65 and 86KA66
Performance of annual legumes and their mixtures under different crop:pasture rotations.
Seed reserves, especially in the 1:1 rotation treatment, are on average below 100 kg/ha and in many cases below 50 kg/ha for all three soil types. Because of this the 1991 season will be used to fertilize, control weeds, and apply a grazing management system to favour legume production and seed set. No crop will be sown in 1991.

Evaluation Of Annual And Short Term Rotation Ryegrasses., Tony Albertsen
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.
