Abstract

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.
