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.

Wheat And Barley Experiments On The Kumarl Soils At Salmon Gums, D A. Collins, Michael D A Bolland, R D. Fletcher
Technical Bulletins
The water-holding capacity of these soils, and their location in a low rainfall area combine to make them marginal for producing grain. In contrast to sowing wheat on ley pasture, mechanically fallowing the year before planting markedly improved grain yields by 1.3 to 4 times.
