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.
