Abstract

The present study was conducted to determine the uptake and accumulation of heavy metals in different parts of vegetable crop spinach and also reduction in heavy metals in the soil due to microbial inoculation. The polybag experiment was conducted following complete randomized block design with 12 treatments and three replications in polluted soil with supply of freshwater, unpolluted soil with supply of freshwater, unpolluted soil with supply of polluted water. The heavy metal concentration of soil, shoot and leaves revels that the nickel and cobalt were more in soil in the treatments T₁₀ (Soil + FYM + VAM + Pseudomonas) and T₂ (SF Soil + FYM + VAM + Pseudomonas). In the shoot, the nickel accumulated more in the treatment T₉ (Soil + FYM), cobalt accumulated more in the treatment T₈ (SF Soil + RDF + FYM + VAM + Pseudomonas) and cadmium accumulated more in the in treatment T₁₂ (Soil + RDF + FYM + VAM + Pseudomonas). The heavy metal accumulation in the leaves showed that nickel accumulated more in the treatment T₁₂, cobalt accumulated more in the treatment T₉ (Soil + FYM) and cadmium accumulated more in the treatment T₈ (Soil + RDF + FYM + VAM + Pseudomonas).
