A greenhouse experiment was carried out in Al- Adawi area, Damascus governorate during two successive seasons (2020-2021 and 2021-2022) to study the effect of PGP Bacteria Bacillus spp. (0, 1.5, 3 g/ l), phosphate oxide (0, 1, 2 g/ plant) and their combinations on growth and productivity of strawberry plant cv. Camarosa. The combination treatment of PGP Bacteria Bacillus spp. (3 g/ l) and phosphate oxide (2 g/plant) significantly promote growth characters (24.48 cm, 26.93, 122.97 cm² and 2.97 for plant height, leaf number, leaf area and runners number respectively), physiological parameters (2.49 %, 0.51 %, 1.82 %, 87.23 % for NPK concentrations and relative water content respectively), and productivity indicators (19.03, 15.13, 227.41 g/ plant, 7.97 for flowers and fruit number/ plant, yield/ plant and number of days required for the fruit set respectively). The lowest values for all studied parameters, however, were recorded in control non treated plants
