摘要

The present research was conducted in Sargodha, Punjab, Pakistan to determine the effect of sewage water treatments on accumulation of some heavy metals (Pb, Cd and Cr) in cv. Dunkeld of canola (Brassica napus L.). The results showed that each metal treatment had its own specific effects on the growth of the canola cultivar. Sewage water application had a significant effect on number of leaves and leaf area, whereas root length remained unchanged. There was a decline in yield and yield related attributes in the treated crop. Soil, forage and seed Pb, Cd, and Cr concentrations increased consistently with increase in the treatment level of sewage water. From the results of the present study, it was concluded that municipal sewage water of cities containing high levels of metals has inhibitory effect on growth and seed yield of canola.
