Abstract

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. ‎
