The aim of this research was to determine differences in chemical composition of strawberry cv. Elsanta fruit in three different cultivation systems and at three harvest times. Th e cultivation systems were: open field, high tunnel and hydroponics, all located in the Zagreb area. Th e harvest times were: the beginning, the middle and the end of strawberry harvest season. In the harvested fruit following parameters were determined: dry matter, total soluble solids (ºBrix), total acid (TA), Brix/TA, pH, L-ascorbic acid, natural invert and total invert. Th ere were significant differences between high tunnel, open field and hydroponics cultivation. Chemical parameters were somewhat highest for fruit grown in high tunnel, and only values of total invert were higher in open field at second and third harvest time. Based on statistical analysis fruit grown in high tunnel had good quality at all three harvest times.
