Abstract:
The pot experiment was conducted by taking three bulk surface soil samples varying in textures. First sample was taken from the sand dune area of Balsamand Village of Hisar District to study the tolerance of heavy metals by different genotypes of maize crop. Second sample was taken from the Atlas Industry effluent polluted field from the Kabirpur Village of Sonipat District to study uptake of Nickle. The soil samples were air dried, grounded and passed through a 2 mm stainless steel sieve and was mixed thoroughly. The processed soil samples were used for laboratory and pot experiments. The pot experiment for heavy metal tolerance study was conducted, taking crops viz., maize (three genotypes J-1006, HM-4 and HKH-1183) on Ni (@ 30, 60, 90, 120 and 150 mg kg^-1) spiked soil. The post-harvest soil samples of crop was analysed for the mean DTPA-extractable Ni as influenced by application of chelating agents. The results revealed that availability of mean values of DTPA-extractable Ni increased significantly with increasing level of Ni. FYM were applied and trend observed was control>FYM>NTA>EDTA>FYM+NTA>FYM+EDTA in maize post harvested soils.
