Abstract
This study aimed to evaluate the effect of Foliar Spraying with different concentrations of nano-zinc on the productivity of red beetroot under water stress conditions, A field experiment was conducted on a research plot next to the Faculty of Agricultural Engineering at the University of Aleppo, during the 2024-2025 agricultural season. A randomized complete block design was used with three replicates was used in the study. 12 treatments were included, resulting from the application of Three irrigation treatments: (irrigation every 5 days, irrigation every 10 days, irrigation every 15 days), and four nano-zinc spray concentrations (0, 50, 100, and 150 mg/l). The results showed that the treatments irrigation every 5 days + concentration 150 mg/l) concentrations significantly outperformed the treatment in (root fresh weight 1462.02kg/m2, root volume 309.88cm3, root length16.55cm). While the treatment (irrigation every 15 days + concentration 0 mg/l) recorded the lowest values (root fresh weight 39.87kg/m2, root volume 9.72cm3, root length 1.57cm). Based on the results of this study, it is suggested to apply the treatment irrigation every 5 days and spraying with 150 mg/l nano zinc to improve the productivity of red beetroot under water stress conditions.
Keywords: red beetroot, Nano-zinc, water stress, productivity.
