Abstract: 

This experiment was carried out in the green house of Al-Adawi area of the Damascus Governorate, and labs of Horticulture Department, Faculty of Agriculture, Damascus University during the period 2020-2021, to study the effect of bio fertilizer, Azotobacter Chroococcum (0, 5, 10 ml/l) and Em1 (0, 4, 8 ml/l) and their interactions on parameters of soil fertility, morphological and chemical growth parameters of strawberry plant cv. Festival. The combination treatment of Azotobacter Chroococcum (10 ml/l) and Em1, (8 ml/l) resulted in the best soil fertility (7.18, 0.28 %, 16 mg/kg, 442.22 mg/kg for pH, total nitrogen, available phosphorous and available potassium respectively), and morphological, chemical growth parameters (2.73 runners, 117.93 cm, 4.27, 2.42 %, 0.49 %, 1.83 %, 3.56 mg/g wet weight, 1.29 mg/g wet weight, 1.07 mg/g wet weight for runners/plant, runners height, number of new plants/runners, nitrogen, phosphorous, potassium, chlorophyll a and b, and carotenoids respectively), The lowest values, however, were obtained in control non-treated plants.

Keywords: Strawberry Plant, Biofertilizer (Azotobacter Chroococcum), Biofertilizer (Em1).
