Organic Matter As A Source Of Nitrogen, N Delroy, R Deyl
Experimental Summaries - Plant Research
The trials can be put into three groups: 1. Plus and minus ripping by species by bag nitrogen. This trial had a number of different species grown in 1982 and half of the trial was ripped in 1983 and the whole site sown to wheat with different rates of nitrogen applied to the subplots. Part of the information on the trial is contained in Bill Bowden's 1983 summary. 2. Species and management trials, namely 82LG5, 82Nl7, 82N041 and 82N03. 3. These trials had a number of different species grown in 1982 to which a number of management factors were applied …

Experimental Summaries - Plant Research
1. Survey of fungi associated with diseased lupin-roots. Cylindrocarpon was only encountered on the south coast (Albany and Esperance districts). The isolates were identified as c. didymum and c. destructans. At certain sites in the two northern districts (Geraldton and Moora) a distinct type of disorder, characterised by reddish-brown coloured lesions which develop on the below ground portion of the hypocotyl, was observed. 2. Assessment of lupin root disease in lupin permanent disease nurseries – 78WH20, 78BA51, 78C34, 78MT38, 80E21. 3. Effect of fungicide drenches on lupin root rots – 83MT17, 83WH9. 4. Mini plot seed treatment trials on lupins …
