This study was conducted in the plastic house in Dokan- As-Sulaymaniyah Government - Iraq during the growing season 2019/2020, to studying the effect of folia application with potassium in three concentrations (0, 50, 100) mg.L-1 and gibberellic acid in three concentrations (0, 100, 200) mg.L-l The experiment was carried out according to a randomized complete block design (RCBD) and the data were statistically analyzed according to the analysis of variance using the SAS system for statistical experiments analysis (SAS 2001, V 9.0), the averages were compared using a Duncan 's multiple range test. The limits are below the probability level of 0.05. The results obtained showed that foliar application Fortuna cultivar strawberry plants with a concentration of 100 mg.L-1 of potassium led to a significant increase in all the study characteristics (leaf area, chlorophyll content, average number of runners per plant. dry weight of the vegetative and root system, average number of flowers and fruits, average weight and size of the fruit, total yield of the plant (as it reached) 52.39 cm2, 39.59 SPAD, 8.69 runner.PIant-1, 17.78 gm, 8.24 gm, 15.82 flowers., 13.27 fruits. Plant, 11.73 gm, 13.9 0 cm3, 87.75 gm. Plant) respectively, while the treatment the Fortuna cultivar with a concentration of 200 mg.1 liter of gibberellic acid significantly in most of the studied traits (chlorophyll content, dry weight of the vegetative and root system, average number Flowers and fruits, average fruit size and total yield (as it reached (37.83 SPAD, 7.18 runner.Plant-1, 16.70 gm, 6.53 gm, 13.77 flowers.plant-1, 13.42 cm3, 68.16 gm.Plant-1) respectively.
