Abstract :This study was conducted in the experimental field of Selcuk University, Agricultural Faculty in 2000. The aim of the study was to determine the most appropriate Nitrogen dose and the effects of different Nitrogen dose applications insert ignore into journalissuearticles values(0-5-10 and 15 kg/da); of four different botany varieties insert ignore into journalissuearticles values(stramonium, inermis, tatula, godronii); of Tube Flower insert ignore into journalissuearticles values(Datu-ra stramonium L.); to seed yield and alkaloid contents and some of its morphological features.The research was ar-ranged in the “split plots of randomized blocks” experimental design with three replications. According to the study results statistically significant differences were observed between varieties and Nitrogen doses with respect of the plant length and seed yield. The highest plant length insert ignore into journalissuearticles values(98,03 cm); and seed yield insert ignore into journalissuearticles values(243,92 kg/da); was obtained from N3 insert ignore into journalissuearticles values(15 kg/da); Nitrogen dose with respect of the mean of varieties. As regards to the mean of Nitro-gen doses the highest plant length 89,40 cm was obtained from var. tatula, and the highest seed yield 213,34 kg/da was obtained from var. stramonium. As regards to the total alkaloid content and yields the highest total alkaloid rate % 0,48 with respect of mean va-riety was obtained in N1 insert ignore into journalissuearticles values(5kg/da); Nitrogen dose and the highest total alkaloid yield 0,87 kg/da was obtained from N3 insert ignore into journalissuearticles values(15 kg/da); Nitrogen dose. As regards to the mean of Nitrogen doses the highest total alkaloid rate insert ignore into journalissuearticles values(%0,40); was ob-tained in var. inermis, and the highest total alkaloid yield insert ignore into journalissuearticles values(0.70 kg/da); was obtained in var. inermis.
