Physical properties of dayri dates fruits are important to the purpose of reducing losses during the harvesting and storage and designing machines, processing, transportation machines, handling, packaging, and assessment of fruit quality, Also, the nutritional composition of this variety of date is important to know the nutritional values of it, the importance of its consumption, the qualities available in it, and comparing it with other varieties of dates and the same variety , but from another country. In this study the average of mass, length, width, thickness, Sphericity, true and apparent volume, surface area, Bulk and True density, geometric and arithmetic mean diameter, porosity, aspect ratio were 5.01g, 33.26mm, 18.89mm, 15.07mm, 63.3%, 5.06 cm3, 3.38 cm3, 13.91 cm2(McCabe), 11.65 cm2(Jean Ball), 0.52 g. cm-3, 0.99 g. cm-3, 21.01mm, 22.33mm, 54.06%, 55%, respectively. Dayri dates are rich in nutritional properties, such as fiber (59.26g/100g), Total solids (96.03g/100g), Energy (143.278 Kcal), Carbohydrate (29.457g/100g), Protein (3.55g/100g), Fat(1.52g/100g), Magnesium (3.81g/100gm), Ash(2.52g/100g), Vitamin B1 (4.44ppm), B2 (2.77ppm), and limited amount or not of Zink, Magnesium, copper, Vitamin (A, E, B6, C). Sucrose was (3.679 ppm) and this amount is high compared to other varieties of dates, on the other hand, the amount of fructose and glucose were lower compared to other varieties.
