Effect of foliar application of graduated Se rates (1.0 and 10 g per ha Se) on the spring barley grain yield and Se accumulation in grain was investigated in the accurate field fertilization experiment. Selenium fertilization was realized together with application of liquid fertilizer DAM-390 (30 kg/ha N) in the growth stage at the end of tillering. Applied treatments of Se fertilization did not influence the yields of grain. Both the rates of 1 and 10 g Se per hectare highly significantly increased Se accumulation in grain in all experimental years. Average Se content in grain dry matter was 0.027 mg/kg under unfertilized treatment and with the Se rates of 1 g and 10 g/ha it increased to the value of 0.049 and 0.073 mg/kg, respectively. The total offtake of Se by grain yield increased in the similar way.
