Research on medicinal plants is one of the most important branches in science. In this project the effects of chemical fertilizers on seed yield of five medicinal plants as follow: Echium amoenum Atropa belladonna. Hyssopus officinalis. Thymus daenensis. Salvia officinalis, were studied. The seed were planted in green house and field during autumn 1994. Plantles transfered in the field in early spring. Fertilizer treatment (Urea and super Phosphat Triple) used in a complately randomized block design with 16 treatment in 4 replication. Result showed that chemical fertlizer increased seed yield and nitrogen had an important role on seed yield.
