Abstract:
The aim of this research was to study the possibility of relying on organic fertilizers (compost of fish pond sediments) to produce chrysanthemum grandiflorum L. in greenhouses with the aim of reducing mineral fertilization. The experiment was designed by complete randomized blocks With 7 treatments: (T1) Control (Farmer), (T2) and (T3) 1/2 Farmer with 2 or 4 kg/m2 compost of fish pond sediments, (T4) and (T5) 1/4 Farmer treatment with 2 or 4 kg/m2 compost, (T6) and (T7) Adding compost alone at an amount of 2 and 4 kg/m2, respectively. T1 and T3 showed superiority on other treatments in most vegetative parameters, with priority for give T3 that recorded higher values for plant height (118.3 cm), number of leaves per plant (158.5 leaves/plant), average number of stem on the plant (12.15 stem), and leaves area. (2601 cm2) and its index (11.56), and improvement the root parameters, so treatment T3 achieved the higher results in size of root (26.5 cm3) and dry matter ratio (21.61%). The three treatments T1, T3 and T5produced higher number of flowering stems ,and longerity of the flowers cut stems, with priority for T3 (4.7 flowering stem), in addition to highest flowers diameter of (9.2 cm). The positive effects were notably reflected on the economic efficiency, T3 achieved the highest profitability coefficient (149.51%) with the best total profit (9,505,000 Syrian pounds per greenhouse).
Keywords: chrysanthemum, compost of fish pond sediments, growth, flowering.
