Abstract: In order to investigate different irrigation regimes effect on quality and quantity of oriental tobacco, an experiment has been conducted with split plot design as a RCB with four replications in Tobacco research center of Urmia during 2006 growing season. A main plots and subplots were allocated to 3 oriental tobacco varieties (Bassma serres 31, Izmir and Zichna) and three levels of irrigation regimes (irrigation after available soil water depletion reached to 60, 80 and 100% ranges), respectively. The means comparison showed that dry leaf yield, usable yield, sugar, potassium and chlorine levels in leaves were maximum in plots that were irrigated after 60 and 80% depletion of available soil water. There were no different between these 2 treatments. Leaf nicotine level was maximum in plots that were irrigated after 100% depletion of soil available water. The results showed that quantities and qualities characteristics of tobacco were the best in plots that were irrigated after 80% depletion of soil available water. The quantities and qualities characteristics of Bassma serres 31 and Zichna tobacco varieties were better than those of Izmir tobacco variety.
