Balochistan, known as the "fruit basket" of Pakistan, particularly for its grape production in Zhob district, faces significant challenges due to water scarcity. Zinc, an essential micronutrient for grapes, influences various growth processes and could potentially mitigate the impact of water stress. This study aimed to evaluate the effects of zinc application on grape yield and quality in the arid conditions of Zhob district, Balochistan, under varying levels of zinc supplementation. The experiment was conducted at the Directorate of Agriculture Research, Zhob, using a randomized complete block design. Four levels of zinc treatments (0g, 10g, 20g, and 40g per grape vine) were applied and assessed for their impact on vine yield, cluster weight, berry weight, titratable acidity, total soluble solids, and pH. Statistical analyses, including ANOVA and correlation studies, were employed to evaluate the treatment effects. The results demonstrated that zinc application significantly increased vine yield, cluster weight, and berry weight. The highest zinc treatment (40g per vine) not only yielded the highest vine production but also significantly improved fruit quality, evidenced by increases in titratable acidity and total soluble solids, and a decrease in pH levels. Statistical analysis confirmed that these improvements were significant at a 1% probability level. Zinc supplementation in grape cultivation offers a promising solution to combat the effects of drought by enhancing grapevine growth and resilience. The study suggests that strategic zinc application can significantly improve both the quantity and quality of grapes in water-scarce regions, supporting sustainable agriculture and economic stability in rural communities. Grape growers in arid regions should consider integrating zinc supplementation into their farming practices to optimize grape yield and quality. Further research is recommended to refine zinc application protocols and explore its long-term impacts on vine health and soil properties.
