Title
IMPACT OF NITROGEN ON VEGETATIVE GROWTH OF MATURE PEACH TREES IN A SUBTROPICAL CLIMATE

Other claims from this paper (6)
- Intervention effect Trunk cross-sectional area and pruning weights did not differ statistically across nitrogen treatments.
- Intervention effect Trees at 0, 45 and 90 kg ha-1 N tended to be smaller than trees at 179 and 269 kg ha-1 N.
- Intervention effect Vegetative and floral buds were fewer at 0 and 45 kg ha-1 N.
- Observation Blind nodes were numerous in all treatments.
- Intervention effect Higher nitrogen rates produced larger canopies requiring more severe pruning.
- Mechanism The authors suggest that declining buds at low N rates may lead to smaller trees and reduced yield.
