Abstract

This study investigates the impact of seaweed and amino acid treatments on vegetative growth characteristics, leaf mineral contents, and yield of grapevines, focusing on two cultivars, Arra 15 and Arra 20. The experiment spans two growing seasons, and various treatments are applied to the vines. The results demonstrate significant varietal differences in vegetative growth characteristics and leaf mineral contents. Leaf mineral content analysis revealed varietal differences, with Arra 15 having higher nitrogen and phosphorus percentages, and Arra 20 exhibiting higher calcium content. The foliar spray treatments positively influenced leaf mineral content, particularly SW 0.75 + AA 0.25 treatment. In terms of yield, Arra 15 consistently outperformed Arra 20. All foliar spray treatments significantly increased yield compared to the control, with SW 0.50 + AA 0.25 treatment producing the highest yield in the first season. The interaction between treatments and cultivars influenced yield, with Arra 15 achieving the highest values under specific treatments. The application of seaweed and amino acid treatments positively influences these parameters compared to the control, with specific treatments leading to the highest values. The interaction between cultivars and treatments further influences these characteristics. Additionally, the study assesses the impact on yield, with Arra 15 consistently outperforming Arra 20. The foliar spray treatments significantly enhance yield compared to the control, and specific treatments result in the highest yields per feddan. The findings of this study contribute to the understanding of the beneficial effects of seaweed and amino acid treatments on grapevine growth and productivity, providing valuable insights for viticulture practices.
