TECHNIQUES FOR CONTROLLING TREE SIZE IN A HIGH-DENSITY PEACH ORCHARD |

| Abstract:
An experimental high-density peach orchard (5000 trees/ha) was established to determine the effects of several planting treatments on vigor of own-rooted 'Redhaven' peach trees. Each planting treatment received 2 levels of irrigation (100% ET replacement and 12.5% ET replacement) during fruit growth stages 1 and 2. All trees were irrigated at 100% ET replacement during stage 3 of fruit development. A polyester fabric positioned in the soil prior to planting served as a barrier to root growth and reduced tree vigor during the second and third growing seasons. Trees with restricted root systems were smaller, had greater flower bud densities and higher fruiting efficiencies than control trees. Differences in tree vigor as a result of irrigation level were not significant for most parameters measured. | |
