A field experiment was conducted to study the effect of ground and leaf additives applied as a foliar spray on on some growth and yield characters of wheat (Triticum aestivum L.). The experiment included dissolving different concentrations were used for the marine extract, and It was doubled the weights up to 30 g in 10 liters of water, spraying in two growth phases, (after tillering andheading) with per treatment (ground fertilizer) N. ha-1, P. ha-1 and K.ha-1. The results were processed statistically with the analysis of variance, and differences between means. The results showed that the treatment of ground fertilizer 30 g, increased significantly the vegetative growth characters and gave the best plant height and leaf area. In general, there were no significant differences between fertilizer treatments when spraying levels increased, but there was a decrease in the number of leaves. Spraying at heading gave the best results for the overall studied growth characters. There is interference; the treatment ground application 30 g sprayed at heading had the highest means. This effect persisted in the yield, grain biological yield components, where the fertilization treatment gave 30 g but there was no significant difference between the treatment of ground fertilization only and other foliar spraying treatments. In general, spraying the mixture at high concentrations doubled the grain yield, for spraying in heading stage compared when ground fertilization.
