Abstract
- A glasshouse study was undertaken to evaluate the effect of lime-treated (0, 0.5, and 1%) industrial sludge amendments (10 and 20%) on wheat (Triticum aestivum L.) seedling growth and heavy metal accumulation in soils as well as in wheat seedlings. Industrial sludge-amended soil samples were filled in earthen pots (2 kg pot-1) one week before planting and 7-day-old seedlings were transplanted in pots (3/pot) and were kept in a glasshouse. Diethylenetriamine pentaacetic acid (DTPA)-extractable metals and metals in seedlings increase with increasing doses of industrial sludge. Biomass and growth have been found to increase with increasing rates of sludge. It also enhanced heavy metal concentrations in wheat seedlings and followed the trend zinc (Zn) > lead (Pb) > copper (Cu) > cadmium (Cd). Lime enhanced the biomass and reduced the heavy metal concentrations in wheat seedlings. Although 20% treatments in both soils showed a significant enhancement in shoot length, metals like Pb reached beyond permissible limits. [ABSTRACT FROM AUTHOR]
