A complete randomized block design with three replications was conducted at two consecutive growing seasons (2014-2015 and 2015-2016) to evaluate the influence of planting date and nitrogen application level on growth parameters and oil yield production of dill plant. Experimental factors included three planting dates (15th of October, 15th of November and 15th of December) and five levels of nitrogen fertilizer (i.e urea) application (0, 30, 60, 90 and 120 kg/hectare). Both studied factors significantly influenced growth parameters (plant height, number of branches per plant, number of umbrellas per plant, 1000 seed weight, above ground biomass yield, seed yield and harvest index) and oil yield and oil percentage The results indicated that early planting date (1st of October) has a positive influence on all studied parameters in this study. Furthermore, this study showed that addition of nitrogen fertilizers significantly improved all studied parameters. Comparing the influence of the two studied factors, it seems that planting date when compared to nitrogen fertilizer application has more pronounced influence on all studied production parameters of dill plant.
