Abstract :Seeds of datura plants insert ignore into journalissuearticles values( Datura stramonium L.); were collected from three different locations insert ignore into journalissuearticles values(Kurupelit, Vadiler Sitesi and Gelemen); and examined at different nitrogen levels insert ignore into journalissuearticles values(0, 50, 100, 150 and 200 kg N/ha); for two years insert ignore into journalissuearticles values(1993 and 1994); in the Kurupelit Campus area of O.M.U., Samsun, Black Sea coastal area. The field experiments were conducted in a split-plot randomized block design with three replications. The highest fresh and medicinal herb yields were obtained by application of 150 kg of nitrogen per hectare, and seed yield was increased by increased nitrogen application levels. Therefore, it may be necessary to test higher nitrogen levels for maximum yield.
