Naji Isam Barwary, Hasan Salim Nabi


This investigation was carried out during growing season (2015 – 2016) on Strawberry (Fragaria X ananassa Duch) Tioga cv.  Planted in the farm of college of Agriculture, university of Duhok, Kurdistan regions / Iraq to study the effect of GA3 with concentration (0, 100, 200 and 300 mg.L-1), and Zinc with concentration (0, 2 and 4 g.L-1), on growth, yield and quality ofstrawberry plant. According to the obtained results the GAand Zinc spraying especially at (300 mg.L-1 and 4g.L-1) respectively caused to improve most of the studied parameters, except of total acidity, decreased with increasing GAand Zinc concentrations. The interaction between GA3 and Zinc at high concentration resulted in the maximum values of leaf area (30.81cm), leaf chlorophyll content (42.53 SPAD), number of fruit per plant (21.07), yield (269.63g.plant-1), Total soluble solids (8.00 %) and anthocyanin (25.43 mg.100-1 g F. Wt).
