Water deficit stress and N fertilizer effect on reproductive growth of henna ecotypes were studied in the split-split-plot form on the basis of a randomized complete block design with four replications in 2013-2014 growing season. The main, sub and sub-sub-plot were devoted to deficit irrigation (100, 75 and 50% of water requirement), N fertilizer (50, 100 and 150 kg/ha) and ecotypes (Bami, Boushehri and Roudbari), respectively. The highest seed number and1000-seed yield belonged to 50% of water requirement and water stress increasing (up to 50% of water requirement) resulted in a severe loss of seed yield at all fertilizer levels especially under 150 kg/ha. According to the results, full irrigation with 100 kg/ha of N had the greatest effect on improving reproductive growth of henna; In addition, it can be said that under water deficit conditions, higher N rates should be avoided because they did not absorb.
