The study was carried out in Lattakia، in cooperation with the Department of Horticulture، and Department of soil and water sciences، Faculty of Agriculture، Tishreen University، during two seasons (2018-2019) and (2019-2020)، The aim of this research was to determine the role of organic fertilization and phosphpgypsum on vegetative growth and flowering of Chrysanthemum grandiflorum،cv.Euro Also investigates the ability of this organic fertilization and phosphogypsum to provide nutrients for the plant in order to reduce the mineral fertilization. phosphogypsum was used for 2kg/m2 applied before planting for one month. The results showed that the use of phosphogypsum and organic fertilization (2kg/m2) had a positive impact on the development of vegetative parameters (plant height and average number of leaves per plant، plant length، leaves the area and proportion of dry matter، chlorophyll content، leaves content from some of the macro elements)، and some root parameters (size of roots، dry matter ratio)،so led to a positive impact significantly on flowering parameters (number of flowering stems ،flowers diameter، floral stem length، number of flowers on the plant). So organic fertilization and phosphogypsum( T4) produced higher results(12.78 flowering stems ، 7.68 cm، 61.91cm، 64.53 flowers on the plant).
Keywords: chrysanthemum، phosphogypsum ،organic fertilize
