الملخص EN

A laboratory study was conducted to determine the nutritional composition of the various tea brands that were imported into Erbil city.

the tea samples included 12 most popular tea brands purchased in various local market and tea shopping with five replications.

the design of experimental based on a CRD.

the results were indicated that the concentration of (P, N, K and Ca%) in all tea samples were ranged between (0.0350-0.1288, 1.0127-5.8086, 0.0028-0.0275 and 0.1306-0.8891) respectively.

the concentration of Mn in tea brands were ranged between (0.0075-0.0325%), the higher concentration recorded in brand2.
