Abstract

       An experiment for the  agricultural season 2017  was carried out 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 sulfate) 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.


We conclude, that the application of Seaweed Extract and Zinc improved the yield contributing factors that resulted in a significant increase in Productivity of Dahlia hybridayield.
