Technical and Economic Efficiency of Vine Pruning: Results of Experimental Trials of Some Cultivars of Grapevine Grown in Sicily and Determination of Break-even Point

The research presents the results carried out on Sicilian viticulture in order to study the economic sustainability of the agricultural company. In particular, the author examined the operation of dry pruning and tying of the fruiting head in espalier vineyards with tools that facilitate the work. The economic analysis highlights that equipping yourself with mechanical tools that facilitate work is convenient for both large and small wineries. The results of the research highlight that the investment to facilitate pruning and tying in Guyot-trained vineyards can also be made by wine-growing companies and is increasingly convenient as the area under vines involved increases.
