Black cumin (Nigella sativa L.) is a medicinal plant with economic influences, especially in medicine production. A randomized complete block (RCB) experiment with three replications was conducted in 2010, to evaluate yield and yield components of black cumin (Nigella sativa) under no irrigation and three different irrigation intervals (7, 14 and 21 days) at research station of Islamic Azad university of Maragheh. Plants were sown in plots 20cm plant to plant distance and 50cm apart rows. Three irrigation intervals had significant effects on all studied characteristics. Results showed that increasing irrigation intervals to 14 days, increased number of capsules per plant, number of seeds per capsules and grain yield per plant, but produced smaller seeds. The lowest numbers of capsules and grain yield per plant were obtained in no irrigation treatment. Lowest Number of seeds per capsules and the largest grains produced in 21 days intervals. Increasing yield per plant in 14 irrigation interval was mainly attributed to the highest number of capsules per plant and number of seeds per capsules.
