| Abstract | ||
| Pepper plants of CV. California Wonder were grown under saline conditions of Ras Suder Research Station, Desert Research Center in South Sinai Governorate, during autumn growing seasons of 2008 and 2009. Eighteen treatments were: Two method application as nine soil addition treatments; control (without addition), iron ores at rate of (25 and 30 kg./fed.), zinc ore at rate of (15 and 20 kg./fed.) besides interaction treatments. Also, nine foliar spray treatments; control (Water spray), 50 and 100 ppm Fe-EDTA, 50 and 100 ppm Zn-EDTA as well as interaction treatments. The treatments were added 30, 45 and 60 days after transplanting. A split plot design was used. The foliar spray method surpassed than soil addition method, also the interaction treatments with highest level of Fe +Zn as foliar spray gave the best values of growth parameters (plant height, No. of branches, shoot fresh and dry weight and leaf area) also, total yield and its components (number of fruits/plant, fruit length, diameter and weight) as well as, chemical composition (total chlorophyll, protein, V.C , nitrogen, phosphorus and potassium, Ca, zinc and iron content of fruits) except Cl and Na gave the lowest values with increasing Fe + Zn level up to (100 ppm ) concentration. | ||
