What is it?

The urgent need for systematic and acceleration of production and to increase the density of the cultivated area, has encouraged the introduction of different farming systems that often are the one, the other variant. In this case study is also part of the system known as "Form V" that represents one of the many variants of the system Fusetti, derived in turn from that to Palmetto. While the latter is suited to crops in rows, the V-shape is used for crops in a single row. And it is most used in the cultivation of the Pear, even if it is spreading as a growing system of Cherry.

How do you get

The V-shape is obtained by tilting the trees alternately in the direction of the middle row, creating an angle of about 15, 20 ° to the perpendicular of the soil, so that, forming, in fact, the shape of a V. The trees must have a minimum height of two meters and the opening at the top must be at least a meter to ensure proper exposure to the sun canopy and vegetative inner wall lighting. The Form V, if carried out carefully following the parameters of the plant aptitude allows to obtain good quality fruits

Disadvantages

The objectives that have led to the creation of Form V is the need to quickly produce the fruits of excellent quality, so the basic use of this farming system is the need to combine quality with quantity. The system also allows you to obtain a discrete density on the surface of the plant cultivated, according to experimental studies on Pear , has resulted in approximately 4000 plants per hectare, certainly a little 'less than other high-density orchards, but the figure is typical of certain types of high density orchards and is also understandable since we are talking of Pear  and seen the amazing results in terms of quality.This system, therefore, gives a lot of quality, but it has some disadvantages in terms of cost of materials and to support the need for labor in the management of the various cultural operations such as pruning and harvesting. The V-shape, in terms of cost and hard work has the same criticality of the system in Palmetto, where the costs of collection and pruning constitute 60% of production costs.

Pruning to Form V

In Form V pruning, generally do not make cuts, but bending. The branches should be pruned, but not shortened. It good to delete a part of those who have already borne fruit: in this case you prefer to bend. But the pruning is done after the fall of the fruit in June. The Form V is applied on more But because this fruit tree can also intervene with the clippings. The pruning of cherry, also in Form V, using the same criteria of the system which provides cord cuts and incisions. The axis of the cordon is pruned by removing the shoots too vigorous or a bad position. The fruiting spurs will be shortened too developed and renovated by cutting back. The formation of side shoots will be helped by special engravings.

Distances and construction parameters

The V-shape allows for an orchard, the density of plants per hectare, 3000 -5000, the distances between rows are 3.5 to 4 meters, while the distance of the plant in the row is between 0.50 and meters. The aston with a year of engagement should be as high 1.2 to 1.5 meters and the second will be tilted angle as in the second paragraph. To keep the V-shape will require support structures consisting of poles, wires and brackets retractors.

Support structures

The V-shape requires support through poles, wires and brackets. In this system are also used ropes that connect the rear anchor posts. The ropes are formed by a tangle of wires in hot galvanized steel, a durable material and durable with good characteristics of low elongation favored by the thickness of zinc. The amount varies based on the use of wires and the resistance that you want. On average, a rope must be composed of 19 wires. The length of the ropes will be modulated according to their position in the system and the distance of the anchors. In Form V will need to use cables with a diameter of 5 mm.

Rootstocks

The cultivation of the Cherrywood with the V-shape requires the use of dwarfing rootstocks that restrict the length growth of the plant to allow the management of farming operations from the ground. But this is just one of the tricks to use with V-Shape. To contain the vegetative activity of the plant must be provided of the bends, but also anulature to remove the rings of bark from the branches particularly vigorous in order to avoid the aging of the hair, reduced fruiting and moving out of the vegetation .
