Reform of Traditional Persimmon Orchards: Demonstration Trials to Renew the Productive Structure
In the territory of Caserta, one of the areas historically most suited to persimmon cultivation, Agronomist Vito Vitelli is conducting several demonstration trials aimed at reforming traditional orchards. These are fruit orchards that have been managed for many years using conventional systems, where over time a physiological imbalance has gradually developed in the trees: an increase in woody biomass and a reduction in fruiting structures.
The approach adopted does not involve drastic interventions across the
entire orchard. Instead, it introduces gradual reform trials on individual
trees in order to monitor their development over the following months and
years. This method allows the farm to directly observe the effectiveness of the
intervention before extending it to the entire orchard area.
During the demonstration, a reform cut was carried out at approximately
70 cm above ground level, with an inclination of about 45°, with the objective
of stimulating the emission of new vigorous shoots at the base of the tree.
In traditional persimmon orchards, as time passes, trees tend to
accumulate an increasing amount of structural wood. To support this woody mass,
the tree continuously produces vigorous shoots which, however, are often
removed during pruning. This creates a vicious cycle: the tree produces
vegetative vigor that is systematically removed, without being used to renew
the productive structure.
The agronomic principle proposed by Agronomist Vito Vitelli is instead
to use these new vigorous branches to rebuild the structure of the tree. The
shoots emerging from the base will become the future productive branches and,
after two or three years of fruiting activity, they can be progressively
renewed through return cuts.
The objective is to obtain, within a few years, trees that are more
balanced, characterized by a reduced but efficient skeletal structure, a
well-developed leaf surface, and numerous active fruiting formations.
Another important aspect concerns planting density. In many of these orchards, the planting layout is 5 × 4 meters, leaving relatively large spaces between trees along the row. This configuration allows, when necessary, the insertion of a new tree in the center of the row, preferably maintaining a north–south orientation.
In this way, it is possible to increase the number of fruiting
structures per hectare, improve light interception, and enhance the productive
potential of the orchard, with positive effects also on the economic
sustainability of the cultivation.
These orchards represent an important part of the Italian tradition of
persimmon cultivation. However, as Agronomist Vito Vitelli emphasizes, even the
most traditional systems must be progressively updated to respond to the needs
of modern olive growing and fruit farming, improving the vegetative–productive
balance of the trees and the profitability of agricultural enterprises.
