Experiment was conducted during summer season of 2021 to study the effect of foliar applications of Phenylalanine (Phe), Jasmonic acid (JA), Biofertilizer (Bio) and their combinations (Phe+JA, Phe+Bio, JA+Bio, Phe+JA+Bio and control) on some growth, yield parameters and anthocyanin compounds on Roselle calyces Hibiscus sabdariffa L., The treatments were distributed on Randomized Completely Block Design in three replicates, means were compared according to the Least Significant Difference test (LSD) at probability level of 0.05. The results show that growth parameters (plant height, branches number, leave area and chlorophyll) and yield parameters (fruits number, fresh weight calyces, fresh yield calyces and dry yield calyces) were increased due by foliar application Phe+JA+Bio, while the combination treatment Phe+Bio gave significant effects on vitamin C, total anthocyanin, Gossypetin, Sabdartine, Hibescitine, Delphidine and Cyanidin of calyces reached at 201.5, 184.5, 29.3, 31.2, 57.4, 35.4, 27.8 (mg.100g) respectively.
