The pollen cultivar and pollination time have important effects on fruit set, and date palm yield and quality. In order to study the effect of date pollinizer cultivar and pollination time on fruit set, growth and development of tissue culture derived date palm cultivar Medjool this experiment was carried out during two years, 2010 and 2011 in date palm and tropical fruit research institute in Ahwaz. The trail was randomized complete block design in factorial manner with three pollen cultivar as Ghaname, Vardy , and Samesmave, tow pollination time is 1-3 days before or after spat opening, four replication. The results showed that the Vardy pollen had significant effects and increased the fertility percent, fruit number per strand, and fruit yield, rather than two other pollen varieties, but had no effects on fruit quality as total sugar, acidity, and bricx. The pollination time before spat opening in cased significant increased in fertility percent and fruit number per strand, decreased fruit weight and date palm yield. Finally the pollen variety and pollination time interaction effects showed that used of Vardy pollen from 1-3 days after spat opening with the most production date palm yield, equal 19.9 kilogram per any date palm tree, is recommended.
