Canola : assessment of early maturing Stage 2 lines.
Location: Katanning, Newdegate Research Station, East Beverley Annex
Production of Canola in medium rainfall zones offers the opportunity for a rapid expansion of the industry. However presently recommended varieties take too long to mature for the area's shorter growing season. The Stage 2 trials assess Canola lines selected on the basis of earliness from the remnants of Dr Roy's now defunct rapeseed breeding programme as well as selections from Eastern States breeding programmes. The trials arc conducted at three sites to account for environmental effects on cultivar …

Phosphorus And Sulphur Nutrition Of Pastures In High Rainfall Areas., M. D. Bolland, M. F. Clarke
Experimental Summaries - Plant Research
J.S.Yeates and M.F.Clarke started these experiments. In January 1990 M.D.A. Bolland replaced J.S. Yeates (who became Regional Manager of the Northern Agricultural Region) as the Research Officer responsible for the management of the long-term experiments, and to continue the research on the topic.
In the experiments the fertilizers wee applied in autumn (March-April) in the years listed in the tables.

New Block Badgingarra Rs Late Time Of Seeding., J. W. Bowden, R. J. Lunt
Experimental Summaries - Plant Research
Trial 89BA33,
Location: Badgingarra
Based on a 1.5 t/ha potential yield, the strategic treatment was planned to be 120 kg urea/ha 4WAS. However, the crop was poorly established and so NH4NO3 was used in the hope of getting better tillering than would be possible with the slower release urea source. Gambling on equal dollars to urea for 2/3 N, but believe that twice as effective.
DAP was used to place nitrogen with the seed in case there was no rain of significance after seeding. This nitrogen (only 5 kg/ha) was probably lost with the rains of 20-28/7/89 (50 mm). Urea …
