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.

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.

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 …

Water Chemistry Survey Of Boulder Basin, Lake Mead, P. R. Tramutt, Bureau Of Reclamation

Publications (WR)

The survey results indicate that the impoundment of water behind Hoover Dam has not adversely affected the dissolved oxygen (DO) content and that water quality and DO content were uniform regardless of depth. The study made in April-May 1964 will provide water quality data of Lake Mead prior to releases from Lake Powell as a basis for evaluating Lake Powell's effect on water quality and limnology of Lake Mead. The performance of a DO analyzer was tested and found unsatisfactory at depths below 150 ft. Parameters tested by standard chemical analyses of water samples in the Denver Laboratory and by …
