The effects of application of CDTA, (CA), DTPA, NTA and FYM on the growth of Zea mays and its Ni uptake and accumulation were investigated using the pot-culture experiments. Application of chelating agents decreased the dry matter yield of roots of Zea mays while, higher values of dry matter yield (11.35 g pot-1) was observedin case of FYM sewage sludge amended soil at 80 days after sowing. FYM addition was found beneficial as compared to control (Ni90). Dry matter yield of shoots of Zea mays increased over control due to application of CDTA and FYM. The highest value of dry matter yield of shoot (86.05 g pot-1) was observed in case of CDTA withsewage sludge amended soil at 80 days after sowing. Whereas reverse trend was observed in NTA, CA and DTPA treated soils. Chelating agents enhanced the Ni uptake by both roots and shoots, higher values of Ni uptake by roots (3415.44 μg pot-1 ) and shoots (10104.98 μg pot-1 ) Was observed in NTA and CDTA treated soil after 80 days of sowing in amended as compared to sewage sludge unamended soil. Application of CDTA followed by NTA was found more effective in enhancing the Ni uptake by Zea mays roots and shoots than any other chelating agents at both the growth stages. The chelating agents are found useful in enhancing phytoextractability of Ni by Zea mays. Hence, marginally Ni contaminated soil may be remediated by adding chelating agents.
