Two field experiments were conduct during the two summer seasons of 2005 and 2006 at the Experimental farm of the National Research Center at Nobaria (Behira Governorate) to investigated the response of pepper plants cv. California wonder to foliar application of some micro-elements Fe, Mn, and Zn. Results indicated that application of Fe 1 g/L + Mn 1 g/L + Zn 1 g/L treatment gave the maximum tallest sweet pepper plants and gave the highest number of leaves and branches. The same treatment gave the highest fresh and dry weights of leaves as well as gave the highest total yield. Moreover, the highest values of N, P and K (%) were achieved using the mixture of Fe, Mn and Zn treatment. However, the highest value of Fe and Mn (ppm) were true when used 2 g Fe/L in the first and second seasons, respectively. The highest significant N, P and K (%) as well as Fe, Mn and Zn were recorded by using (Fe 1 g/L, Mn 1 g/L, Zn 1 g/L) treatment.
