Abstract: The effects of different doses of nitrogen (0, 6, 12, 18 kg/da N) and various densities of plants (20x20, 30x30, 40x40, 60x60 cm) on the yield and quality traits of (Lavandula angustifolia Mill.) were investigated in the experiment conducted for four years in under ecological conditions of Bornova. The quantity of Flores lavandulae was defined on average 234 kg/da in 1988, 286 kg/da in 1989, 142 kg/da in 1990, the density of plants increased the yield significantly in terms of statistical. Maximum yield was obtained at variation of 30x30 cm (11.100 plant/da). The essential oil rates ranged on average from 1.30 %, in 1988 to 1.23 %, in 1990. N-fertilization and densities of plants had no significant effect on essential oil rate. However, Linalyl acetate rate in composition of essential oil varied on average from 11.7 % to 29.3 % for the years.
