Considering the removal of soil in soilless cultivation and the lack of supply of some beneficial elements in the nutrient solution, using them in the conditions of soilless cultivation can effectively improve plant growth. This research was conducted with the aim of investigating the effect of root and foliar application of selenium on vegetative growth, fruit quality and yield of Queen Elisa strawberry. The experiment was carried out using eight treatments and four replications in a completely randomized design. When the plants had four to five leaves, sodium selenate was foliar applied at three concentrations (2, 4, 6 mg.l-1) at two-week intervals and root application at three concentrations (1, 2, 3 mg.l-1) along with in nutrient solution, and 2 mg.l-1 of foliar application and root application of 1 mg.l-1 as well as control treatment. The results showed that the most effective treatments were treatments 1 and 2 mg.l-1 sodium selenate. The highest weight of primary fruits was obtained in the treatment nutrition solution of sodium selenite 1 mg.l-1. Treatment sodium selenite 2 mg.l-1 showed more increase in the amount of anthocyanin and antioxidant activity of fruit. The most amount of iron (Fe) and zinc (Zn) were in the treatment solution of sodium selenite 1 mg.l-1 with 140.06 and 17.83 mg.kg-1 of dry matter, respectively. Thus in this study, root application had better results at different levels than the foliar application of sodium selenate.
