| Abstract | ||||
| Pot experiment was carried out during the two summer consecutive seasons of 2020 and 2021 at Ornamental Nursery of EL-Quassasin Horticultural Research Station, Ismailia Governorate, Egypt. This study aimed to investigate the impact of different potassium fertilizer rates (0.0, 1.5, 3.0 and 4.5 g/pot) as potassium sulfate (48% K2O), lithovit concentrations (0.0, 0.5, 1.0 and 1.5 gl-1) and their combinations on vegetative growth, flowering characters and chemical contents of Jasminum sambac plant. The achieved results revealed that maximum plant height, No. of branches and leaves/ plant as well as fresh and dry weights of plant were recorded when plants were fertilized with potassium sulfate at 4.5 g/pot compared to the other rates under study and control. Also, the vegetative growth traits were increased gradually as lithovit concentrations increased to reach the maximum values with 1.5gl-1. Using of any potassium fertilizer rates or lithovit concentrations individually, significantly increased flower number per plant, flower diameter and petal number per flower compared to control. In general, fertilizing Arabian jasmine plants with 4.5 g/pot potassium sulfate and spraying with 1.5 gl-1 lithovit recorded higher values of growth traits and flowering parameters as well as chemical constituents of leaves compared to the other combination treatments. Therefore, this treatment can be recommended to apply it to the Arabian jasmine plant under the same conditions. | ||||
