Water deficit is one of the most importance of environmental tensions that has affected crops production and causes reduction in quality and quantity of agricultural production. In order to investigate the effect of water tension and application of different amounts of zeolite, two experiments were carried out as split plots in randomized complete blocks design with three replications in Payam Noor University of Markazi province in 2009-10 cropping years. Water tension as the main factor in four levels include: irrigation on the basis of plant water requirement (control), irrigation to the amount of 85, 70 and 55 percentage of plant water requirement were assigned in the main plots and different amounts of zeolite application as the sub factor in four levels include: without zeolite consumption (control), consumption three, six and nine tons per hectare zeolite in sub plots. The results showed that the effect of water tension treatment was significant on traits biological yield, number of unfertile boll, water saturation deficit, plant height, stem diameter and leaf eternity water. The effect of zeolite application was significant on traits number of unfertile boll, water saturation deficit, plant height, stem diameter and leaf eternity water, too. Plant biological yield was significant at one percentage level. As the highest amount of biological yield 8186 kilogram per hectare was related to control irrigation treatment and the lowest amount 6756 kilogram per hectare was due to sever water tension treatment (irrigation one the basis of 55 percentage of plant water requirement). Generally, increasing water tension severity, caused reduction in the amount of biological yield, plant height, stem diameter and leaves eternity water of safflower. But with increasing levels of zeolite consumption, the adverse effect due to water tension treatment on mentioned traits decreased.
