Title

Other claims from this paper (10)
- Intervention effect Excessive thinning or irrigation can lower fruit calcium concentration.
- Intervention effect Manurial (N, P, K) and soil management treatments had little effect on calcium concentration other than via fruit size.
- Intervention effect Soil application of calcium sulphate can increase fruit calcium concentration slightly without altering fruit size.
- Intervention effect Late sodium nitrate, rather than early ammonium sulphate, can increase fruit calcium concentration slightly without altering fruit size.
- Intervention effect Judicious irrigation can increase fruit calcium concentration slightly without altering fruit size.
- Intervention effect A combination of these treatments with an effective calcium spray programme could result in large increases in fruit calcium concentration.
- Association Fruit calcium concentration is inversely related to mean mass per apple.
- Association Calcium concentrations in apples are dependent on orchard environment and management in addition to nutrition.
- Association Significant deviations from the average calcium curve can occur with weather during the growing period and sometimes from biennial tendencies.
- Recommendation Adequate numbers of apples must be analysed to detect the small changes in calcium concentration induced by orchard treatments.
