Abstract
In order to study the effects of drought stress and some types of organic and inorganic fertilizers on quantitative and qualitative traits of dragon , s head (Lallemantia iberica), a field experiment in a factorial under randomize complete block design with three replications was conducted in 2012 at University of Tabriz. Irrigation treatments (I1, I2 ,I3 and I4: irrigation after 70, 110, 150 and 190 mm evaporation from class A pan) and fertilizers treatment (compost (5 ton/ha), vermicompost (2.5 ton/ha), animal manure (7.5 ton/ha), nitrogen (60 kg/ha in the form of urea (46% N) was applied in 3 equal portions, 1/3 in sowing, 1/3 in stemming and 1/3 in flowering) and control) were assigned to plots, respectively. By increasing the interval of irrigation periods, biological yield, seed yield and seed number per plant decreased. 1000-seed weight and harvest index did not affected by water deficit stress. Fertilizers effected all traits that nitrogen and manure had the highest effect. In both water deficit stress and fertilizers, control treatment had the lowest effect on traits.
