| Abstract | ||||
| Copper is an essential nutrient needed for the normal growth and development of cereal crops. Chlorophyll production, protein synthesis and respiration are important plant functions that need copper, involved in the manufacture of lignin (cell wall). About 70% of the copper in plants is found in the chlorophyll. Copper deficiency was noticed during season 2010-2011 in Egypt at El-Wahat Oasis (Western desert area), 320 Km western of Cairo, on the wheat cultivars, i.e. Sakha-93 and Giza-168, in eight centre-pivot (720 Faddan). Symptoms noticed were wilt (Fig. 1), pigtail on leaves (Fig. 2), melanosis (Fig. 3) and partial or complete bleached on ears (Fig. 4). Copper determined in both water and soil was 0.00-0.02 and 0.04-0.22 ppm, respectively, and this is insufficient for normal wheat growth, while wheat plants need 1ppm of copper for normal growth. | ||||
