In this study it was aimed to investigate the effect of biogas digested (BD) on the growth and some potential toxic element (B, Cd, Cr, Ni, Co and Pb) concentrations of wheat grown under greenhouse conditions. For this reason, 0, 15 and 30 tha-1 of BD were applied to the soils and left incubations during 0, 30 and 60 days. After incubation period is ended wheat seeds were sawn and left for growth during 2 months. Results indicated that BD dosages and incubation periods increased plant dry weight. Applications of BD did not affect B, Cd and Co concentrations of wheat and Cr and Ni concentrations decreased generally with the BD dosages. Similarly, incubation showed decreasing effect on Pb concentration of wheat. Plant Co, Cr and Pb uptakes did not vary with the applications, other element uptakes increased in the parallels of plant dry weights. Looking at the element concentrations of wheat it was seen that all element concentrations were in the ranges of acceptable levels. So, it was concluded that the application of BD did not pose a risk for potential toxic elements on the growth of the wheat.
