Abstract
The current study focuses on fourteen dates (Phoenix dactylifera L.) fruit cultivars from diverse places that were gathered at the mature stage for the examination of eleven elements using inductively coupled plasma optical emission spectrometry. The materials were pretreated using the wet digestion procedure. Micro and macro nutrition studies indicated that the greatest sodium (515mg.kg-1), potassium (2715mg.kg-1) and calcium (364.33mg.kg-1) were recorded in Zagyol and Kashkari, who held the lowest level of potassium (1984mg.kg-1) and iron (1.77mg.kg-1). In the case of Magnesium (1517mg.kg-1), Manganese (56.13mg.kg-1), and Chromium (1.36mg.kg-1), the greatest value was studied in Ajwa, whereas the lowest values of Magnesium (910.75mg.kg-1), Manganese (19.53mg.kg-1), and Chromium (0.22mg.kg-1) were identified in Begium Jangi and Karbalian correspondingly. Otakon holds the largest values of iron (14.33mg.kg-1) and copper (1.63mg.kg-1), but the bottommost level of copper (0.24mg.kg-1) was detected in Hussani. At the same time, the utmost accumulation of nickel (3.42mg.kg-1) was detected in Shakri. At the same time, the lowest level of nickel (1.31mg.kg-1) was observed in Pushna. The topmost value of cadmium (1.13mg.kg-1) was discovered in Allie. Moreover, the minimum quantity of sodium (156mg.kg-1) and cadmium (0.13mg.kg-1) was reported in the Safawi date variety. Lead was not identified in any types of date fruit. Keywords: Date Fruits, Micro Nutrition, Macro Nutrition, Trace Elements, Wet Digest
