It is a permanent cordon and medium-long pruning system derived from the Sylvoz method. The variant originated, by necessity, in times of war in the municipality of Casarsa della Delizia (Pordenone). It is said to be the work of the wives of winemakers sent to the front and left alone to lead vineyards, or according to another version of an elderly winemaker whose children had gone to war. During the winter, in addition to the cold, women did not have time to practice winter pruning; thus they moved it to spring when, with longer days, they could find the time not only for all the other jobs, but also to devote themselves to the vineyard. Having equally little time available, however, they neglected to tie the heads to fruit. The production results were satisfactory and then this system spread and spread more than the original Sylvoz.
The plant has a trunk 1.5 to 1.8 m high which continues horizontally; from this start fruiting heads shortened to 50-70 cm, understandable six to 10 buds And then set free. Under the weight of the vegetation and the clusters, the fruit heads arch downwards and the shoots that will be used for renewal arise from the basal part. The distances vary, according to the fertility of the soil, from 1.5 to 3 m on the row and from 2.8 to 3.5 m between the rows.
In the Casarsa system, the vineyard poles, preferably in galvanized steel, are in the row from six to 8 m with a height from the ground of about 2.5 m. In addition to the iron wire that carries the cord, two other upper sons are needed to support the renewal vegetation; the latter is fixed to the upper thread during the vegetative period, at the end of flowering, while the production area is positioned below the permanent cord. The bunches are for the most part well exposed and clearly visible. On the Casarsa system it is possible to practice both pruning and mechanical harvesting.
