Sesame is one of the oldest crops in the world that is commonly cultivated in arid and semi-arid due to high oil seeds (42-52%). In order to determine the effects of water deficit (55, 75 and 85 percent evacuation of soil water) on genotype sesame (Varamin, Naztakshakhe, Oltan and Yekta), a field experiment was conducted using a split-plot in randomized complete design with three replication at...
