Impact of wastewater irrigation on germination, growth seedling and concentration of heavy metals in soil and Canola (Brassica napus L.)

2014 International Journal of Biosciences  
The present research was conducted in Boruojerd, Lorestan, Iran to determine the effect of wastewater irrigation treatments on accumulation of some heavy metals (Fe, Mn, Zn, Cu, Pb, Cd and Ni) in root and shoot canola (Brassica napus L.viz., SLM046). The experimental design was random complete blocks with five effluents treatment and 4 replicate lysimeters (20 lysimeters) in the field. Wastewater irrigation application had a significant effect on seed germination, shoot length, length of

Soil, root and shoot Fe, Mn, Zn, Cu, Pb, Cd, and Ni concentrations increased consistently with increase in the treatment level of wastewater (T4). From the results of the present study, it was concluded that municipal wastewater of cities containing high levels of heavy metals has inhibitory effect on growth and seed yield of canola.
