- Espaldero DOV – A New Training System Design for Mechanical Raisin Harvest Rodrigo S. Espíndola S. Mayor T. Lloveras M.L. Agüero Agrociencias dry on vine shoot length Number of shoots Farmers around the word are increasingly interested in the adoption of mechanization methods, especially in dry-on-vine raisin production. The lack of profitability in the raisin industry is a problem that demands the development of new technologies that allow mechanical raisin harvesting, leading to reduced investment. The aims of this research were to assess the performance of two designs of Espaldero DOV on raisin production and to measure the vegetative and productive features of Fiesta grapevines in San Juan, Argentina. The double and the simple Espaldero DOV were designed based on three trellis systems: Scott Henry, T-trellis and single-wire trellis. A completely randomised design with three replicates was performed. In the growing season, the number of shoots and clusters per meter, shoot length, leaf area, raisin yield (kg/m) and manual and mechanical harvest losses were determined. Descriptive statistics and ANOVA were performed. There were no significant differences in the number of shoots, shoot length, and leaf area between Simple Espaldero DOV and double Espaldero DOV. Among them, double Espaldero DOV almost duplicated simple Espaldero DOV production (7.8 t/ha vs. 4.1 t/ha respectively). However, according to the literature, both technologies reduced the yield per hectare compared to other DOV trellis systems or Parrales. Both growing systems allowed a mechanical harvesting with 98% efficiency, making this the main advantage of this technology due to the markedly lower harvesting costs. 2024 artículo científico 0325-8718 https://www.redalyc.org/articulo.oa?id=86480837007 https://www.redalyc.org/journal/864/86480837007/ https://www.redalyc.org/journal/864/86480837007/html/ https://www.redalyc.org/journal/864/86480837007/86480837007.epub https://www.redalyc.org/journal/864/86480837007/movil en http://www.redalyc.org/revista.oa?id=864 RIA.
