Abstract
Mycorrhizal symbiosis increase nutrient uptake and enhance plant growth by elaborating root system. The positive effects of mycorrhizal symbiosis on the growth, physiology and ecology of various plants have been recognized. The symbiotic relations between mycorrhizal fungi and date palm with regard to nutrient uptake by this plant have not yet been explored and studied in Iran. This project was conducted as a randomized complete block design with four replications (blocks) in a greenhouse at Date Palm and Tropical Fruit Research institute during 2008 to 2009. Factor A such as; five rate of fertilizer superphosphate triple (0, 5, 10, 15, 20 mg/kg soil), factor B including; with or without mycorrhiza inoculation. Fresh and dry weight of shoots and roots, root length, mycorhizal root length and nutrient concentration in different treatments were measured. The results showed significantly differences between dry weight of roots and shoots, nitrogen, potassium and phosphorus in shoot and roots (P
