Drought and nitrogen deficit are the most important abiotic stresses in agriculture. Iran is one of the countries located in the arid belt of the earth, and most parts of Iran are located in arid and semi-arid areas and have limited water resources. In order to study of effect of drought and nitrogen on dill seed quality traits, a field experiment was conducted as split plot design at research farm in Razi University in 2013. Main plot (irrigation interval) included three levels; irrigation interval of 4, 6 and 8-day and split plot (urea fertilizer) included four levels; 0, 100, 200 and 300 kg ha-1. Results showed that irrigation interval of 8-day with the highest rate of nitrogen produced the highest essence content and yield. While irrigation interval of 4-day with application of highest rates of nitrogen produced the highest α-Phellandrene percentage. Trans- Dihydrogen and Limonene were not affected by nitrogen rate and irrigation interval. It seems that dill is a plant with low water requirement.
