Experimental Summaries - Plant Research

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.

Rates, Times And Sources Of Nitrogen On Wheat, J W. Bowden

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.
