To evaluate the effect of different doses of zinc sulphate and potassium sulphate on morphological characteristics of sunflower under saline conditions, an experiment was conducted as split plot in a randomized complete block design with three replications at the Agricultural Research Station of Zahak, located 20 km south of the Zabul city. In this experiment, the type of irrigation in two levels includes irrigation with salinity water (S) and irrigation with fresh water (N) were considered as the main treatments and zinc sulfate (ZnSO4) and potassium sulfate (K2SO4) were considered as as sub treatment. Morphological traits evaluated include plant height, head diameter, number of leaves. The results showed that a morphological trait in irrigation treatments in both normal and salinity mode was significant at the five percent level and performance was significant at the one percent level. Above traits due to fertilizer treatment was significant at the one percent level, Interaction of irrigation conditions and fertilizer are significant at the five percent level. Average comparison of traits in the interaction of fertilizer and irrigation conditions showed that all traits measured have maximum amount in the treatment of 60 kg zinc sulfate and 250 kg potassium sulphate in normal irrigation conditions (N-Zn3-K3).
