- Intervention effect Nitrogen increased sucrose content.
- Intervention effect Nitrogen increased cane yields.
- Association Percent increases in cane tonnage and sucrose percentage had a highly significant regression.
- Association A significant sucrose increase occurred only when yield increases exceeded 27 percent.
- Intervention effect Ammonium nitrate, ammonium sulfate and Uramon did not differ significantly in effects on sucrose.
- Intervention effect Phosphorus had no significant effect on sucrose content.
- Intervention effect Cane tonnage responses to phosphorus were slight.
- Intervention effect Potassium fertilizer did not significantly affect sucrose content.
- Association Where yield increased with potassium, sucrose content generally increased.
- Intervention effect Most potassium associated cane yield increases were below 10 percent.
- Intervention effect Minor element fertilizers caused no significant sucrose increase.
- Intervention effect Boron, manganese and calcium produced no appreciable yield increases.
- Intervention effect Sodium, iron and sulfur produced no appreciable yield increases.
- Observation Most minor element yield increases were below 7 percent.
- Observation Sucrose content changes with minor elements ranged from −3 to +7 percent.
