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 Indian mustard and maize crops. Second from the sewer water and sewage sludge polluted fields near the main disposal outlets behind main bus stand of Hisar to study uptake of Cadmium. 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 maize (three genotypes J-1006, HM-4 and HKH-1183) on Cd (@ 30, 60, 90, 120 and 150 mg kg-1) and Ni (@ 100, 150, 200, 250, 300 mg kg-1) spiked soil. From these investigations it is apparently clear that genotype J 1006 of maize can be grown successfully in soils having low to medium levels of pollution due to industrial wests, sewer water and sewage sludge. However, if the pollution persists and the heavy metals are accumulated in slightly toxic quantities below a threshold level, soil amendments with FYM and use of EDTA would be desirable to raise crops with reasonable success.
