Four kinds of growing media (clay, sand, clay + sand and calcareous soil) and two different locations (open field and green-house conditions) were used for Cycas seedlings of one-year-old in two experiments during 2003 and 2004 seasons at Antoniades Research Branch, Horticultural Research institute, Alexandria Egypt. The results indicated that growing the plants ¡n clay soil or clay + sand in open field gave the highest values in the number of leaves! plant, leaflets number! leaf, stem fresh and dry weights, root fresh and dry weights and total chiorophylls content. While, growing the plants in clay soil or clay + sand ¡n the green-house led to the highest values n the leaf and leaflet length, leaves fresh and dry weights and stem circumference. But, growing the plants on calcareous soil in open field gave the smallest values in all the studied parameters.
