Other claims from this paper (7)
- Intervention effect Soil applications of extra nitrogen had no effect on growth and cropping parameters of apple trees compared with control trees
- Intervention effect Foliar sprays of extra nitrogen promoted shoot growth and leaf extension of apple trees compared with control trees
- Intervention effect Foliar sprays of extra nitrogen decreased yield and crop-load of apple trees compared with control trees
- Mechanism The decrease in yield and crop-load under foliar sprays is presumably due to greater preharvest fruit drop
- Observation Phytotoxic damage was observed on the leaves of apple trees under overfertilization
- Observation Net photosynthesis of apple trees remained unaffected by overfertilization
- Intervention effect Overfertilization did not change the mineral element concentration of apple trees
