Abstract

The cultivation of high-quality grapes is essential for the global wine and table grape industries. Micronutrient application has gained attention as a means to enhance grape quality and yield. This study comprehensively evaluated the impact of foliar application of various micronutrients on the quality characteristics and yield of grapes cv. Superior Grape over two consecutive growing seasons (2022 and 2023). The results demonstrated the differential responses of grape quality parameters to the micronutrient treatments. In 2022, the application of watercress (NPK+0.05% Watercress) and selenium (NPK+10 ppm Selenium) resulted in the highest cluster weights, while in 2023, watercress oil (NPK+1% Watercress Oil) and selenium (NPK+10 ppm Selenium) improved the package size. The numbers of large and small beads were significantly influenced by the application of NPK Fertilizers, NPK+5 ppm Silicon, and NPK+10% Wormwood. The total soluble solids (TSS) were highest with the NPK+10 ppm Selenium and NPK+10% Chamomile treatments. The variability observed in the effects of micronutrient treatments between the two growing seasons underscores the complex and dynamic nature of the grape-micronutrient interaction, which can be influenced by various environmental factors. The findings highlight the potential of specific micronutrients, such as watercress, selenium, and chamomile, to positively influence key grape attributes. Further research is needed to elucidate the underlying physiological and biochemical mechanisms and optimize micronutrient management strategies for sustainable and consistent grape production.
