Experimental Summaries - Plant Research
Trial 67E8
Location: Esperance Downs Research Station.
The trial was originally designed to measure the residual effectiveness of rates of copper sulphate drilled in 1967.

Matricaria/Globe Chamomile (Pentzia Globifera) Density And Seed Production, J. Dodd
Experimental Summaries - Plant Research
Location: Muckinbudin.
Preliminary measurement of plant density and seed production were made in November 1987 at two infested properties near Muckinbudin.
Vermin fence herbicide trials (Established by J. R. Peirce 85ME63, 65, 68, 69, 70)
During assessment of the vermin fence herbicide trials in November 1987, certain plants in the sprayed plots were noted as being undamaged, even by the highest rates of herbicides used.

Project title: Evaluation of existing diagnostic procedures for the recommendation of trace element fertilizers.
Aim: To compare the accuracy and reliability of a range of tissue and soil tests being variously promoted for use to farmers for the diagnosis and prognosis of zinc and copper deficiencies in wheat crops on Western Australian farms.

Phosphorus Levels And Disease On Lupins, J W. Bowden
Phosphorus Levels And Disease On Lupins, J W. Bowden
Experimental Summaries - Plant Research
Trial 87LG39 (81LG29) 87ME62
Location: Pingaring.
It has been suggested that high levels of phosphorus application to lupins can reduce the impact of leaf and root diseases. Two old rotation trials provided a range of disease burdens, across which phosphate rates on lupins were applied. Disease scores, vegetative yields, phosphorus concentration and seed yields were measured.

N X P X Irrigation On Wheat - South Carabin, J W. Bowden
Experimental Summaries - Plant Research
Trial 87M7.
Nx P x irrigation on wheat
Although no major effects of fertilizer on average seed size were noted, it was found that phosphate level had an effect on the distribution of seed sizes.
Location: South Carrabin.

1987 rainfall.
Location: Wongan Hills Research Station.
Harvested And Grazed Lupin Stubbles On Following Wheat South Carrabin., J W. Bowden
Harvested And Grazed Lupin Stubbles On Following Wheat South Carrabin., J W. Bowden
Experimental Summaries - Plant Research
Location: South Carrabin lease block
Harvested and grazed lupin stubbles on following wheat. Trial 86M8
This trial is difficult to analyze statistically because of the treatment changes induced by sheep breaking in to some of the plots. Further, lupin grain yields were not very high and so differences between harvested and unharvested treatments are not large. Also the grazing intensity was not very severe (except on the unintentionally grazed plots) and so the effect of grazing is also relatively small.
Trial 87M7
Nitrogen phosphorus and irrigation of wheat.
Location: South Carrabin.
This trial was designed to give a nitrogen/phosphorus response …

Residual Value Of Phosphate Fertilizers., M D A Bolland, M Baker, C. H. Phillips, D. Proudmore
Experimental Summaries - Plant Research
Trial 84M63
Residual value of phosphate fertilizers.
Location: South Carrabin Block of Merredin Research Station.
4th successive crop on new land. Trial has shown that the effectiveness of the different types of rock phosphate were about the fifth to one tenth as effective as the fresh (triple) superphosphate applied in 1984. The effectiveness of the superphosphate, decreased by 60 between year 1 and 2, and by a further 10-15% by 1987. This experiment will continue as pasture for 1988 and 1989, and will be re-cropped in 1990. The experiment is also assessing soil testing for P. but soil test data …
