An experiment for the agricultural season 2017 was carriedout in pots in the Autumn season to study the effect of application three levels of Sea Top foliar fertilizer (0, 50,and 100 gm.L-1) and Three levels of zinc (zinc sulphate) was ( 0, 30, and60 mg. L-1) with three times spraying intervals every20 days for some of the growth and yield parameters of the Dahlia cv. Albion. The spray concentration of zinc sulfate at level of 60 mg / L-1 and Seaweed at a level of 100 mg / L -1 had significant differences in plant height, number of branches ,number of flowers per plant, flower diameter, fresh weight of flower,fresh weight of the tuber , number of tubers per plant, fresh weight of the stalk,and dry weight of the vegetative parts ,compared with the control treatment.The increase was 115.16, 6.33, 12.0, 15.53, 25.66, 371.36, 6.66, 46.56, and 60.16 for the above qualities respectively.
