Trial 65SG5. Location - Paddock H5 on Salmon Gum Research Station
Cleared in 1962, then cropped until the start of the trial in 1968. Two of the four blocks were sown to Cyprus Barrel medic which is topdressed with superphosphate. The other two blocks regenerate volunteer pasture which is not topdressed. In 1984 all pasture plots were sown to SERENA medic. This grew exceptionally well in 1984 and set a lot of seed. In 1987 field peas were introduced into 4 reps of an existing medic: crop rotation.

Experimental Summaries - Plant Research
Trial 87WH51
Location: Wongan Hills Research Station.
This trial was put onto a site adjacent to Mel Mason's source of nitrogen trial and the CSIRO, 15 N plots to provide some explanation of the results from the limited treatments in those trials. They were designed to monitor soil/fertiliser nitrogen transformations with time. Unfortunately the site of this trial was variable. The end most similar to the other trials was deeper and sandier and stored less water than the other and where crop growth was far better.

Post Emergence Weed Control In Lupins., R. Madin, J. Buckley
Experimental Summaries - Plant Research
As a general assessment in can be said that Tigrex is a safe and efficient herbicide for control of radish in wheat. Brodal alone was generally unsatisfactory for radish control. While Diuron + Brodal was safe and efficient, Ally and Brodal should not be used together. Diuron + MCPA gave poorer control than one would normally expect.

Manipulation Of The Soil Seed Reserves Of Bromus Diandrus And B. Rigidus By Enhancing The Breakdown In Seed Dormancy., A H. Cheam
Experimental Summaries - Plant Research
Location: South Perth Field Plots
Previous studies on the seed bank of Bromus diandrus indicated that shallow burial of newly shed seeds enhanced the breakdown in seed dormancy over the summer period. To bury the Bromus seeds one practical approach is to introduce sheep into the paddock.
This study is a repeat of the previous work but included B. rigidus, another species of Bromus, that is commonly ground growing in association with B. diandrus.
Location: South Perth Field Plots.
