Abstract :This research has been conducted under Konya ecological conditions to determine the effect of nitrogen and zinc applied in diffe-rent doses on the yield and yield components of fennel insert ignore into journalissuearticles values(Foeniculum vulgare Mill var.dulce); in Experimental Farm of Field Crop De-partment, Agriculture Faculty, Selcuk University, in 2003. Experiment was designed based on”Randomized Factorial Plot Design” with three replications of the sets nitrogen insert ignore into journalissuearticles values(0, 5, 10 and 15 kg/da); and zinc insert ignore into journalissuearticles values(0, 250, 500 and 750 gr/da); fertilizer with different doses. In this research, seed yield, essential oil rate and yield were found between 13.7-25.4 kg/da, 2.9-3.2 %, and 0.4-0.7 kg/da, res-pectively. Avarage values for other the characters were as fallows; emergence period is 17.3-24.0 days, lenght of plants 51.7-64.0 cm, seed yield per plant is 0.8-1.7 g, weight of thousand seed is 8.0-9.2 g, number of brunch per plant is 3.1-4.8, number of seed per plant is 98.8-193.6 and harvest index is 3.4-7.9 %. While the highest seed yield was obtained from the control group insert ignore into journalissuearticles values(25.4 kg/da); that nitro-gen and zinc has not been applied, the lowest seed yield was from the group insert ignore into journalissuearticles values(13.7kg/da); that received 15kg/da nitrogen and 750 g/da zinc. The highest and lowest essential oil ratios were from the group of 15kg/da nitrogen, 500 g/da zinc insert ignore into journalissuearticles values(% 3.2);, and 5 kg/da nitrogen and 500 g/da zinc insert ignore into journalissuearticles values(% 2.9);, respectively. Essential oil yield was found in the plots in which seed yield was also the highest.
