Abstract
This study was conducted on a private farm in Mit El-Karmeh village, Talkha District, Dakahlia Governorate, Egypt during the summer seasons of 2023 and 2024 to study the effect of foliar spraying with titanium (Ti) as form of titanium dioxide (TiO3) and selenium as form of sodium selenite (Na2SeO3) at the following concentrations (0, 5, 10, and 15 mg/L each) and their interaction on the growth, productivity, and quality of potato tubers (Spunta cultivar) grown in clay soil. The most important results obtained were as follows: The interaction between spraying potato plants with both titanium (Ti) and selenium at a concentration of 15 mg/L for each of them) four times at 20, 40, 60, and 80 days after planting recorded the best values for each of the vegetative growth traits represented by plant height, number of leaves and stems per plant, leaf area per plant, fresh and dry weight of the foliage , and chemical characteristics of the shoot such as total chlorophyll in leaf tissues, the content of nitrogen, phosphorus and potassium at 90 days after planting Also this treatment increased the yield and its components (average tuber weight, plant yield and yield/fed.) and improved the quality characteristics of tubers at harvest, represented by the percentage of dry matter, specific gravity, tuber content of soluble solids, vitamin C, percentage of protein and starch, and selenium concentration.
