Nigella sativa, from the Ranunculaceae family with a short life span, is special of a semi-arid region. Due to water scarcity in our country, a factorial experiment was conducted in a randomized complete block design at University of Tehran, Aboureihan Campus in 2018- 2019. Experimental treatments included 14 ecotype cultivars and three levels of irrigation (crop capacity, 50 and 70 percent crop yield). The results of this experiment showed that khaf mass had the highest amount of chlorophyll a, carotenoid, anthocyanin radar. Proline content increased with increasing stress level
