Online published on 20 May, 2023. Abstract Heavy metal like cadmium is a toxic metallic element that poses serious human health hazards through consumption of contaminated agricultural produces when present in high concentrations in soil. To address this problem pot experiment was conducted in 2018 in the net house. Six cadmium levels (0, 20, 40, 60, 80 and 100 mg/kg) with and without two levels of biochar @ 20 ton/ha and 40 ton/ha respectively were taken. Chemical properties of post-harvest soil (pH, EC, Organic Carbon, N, P2O5, K2O and Cd Content), Cadmium content in root, straw and grain, Enrichment Factor (EF) and Translocation Factor (TF) of rice were recorded. Results directed that these parameters were adversely affected by cadmium. Chemical properties of post-harvest soil (pH, EC, Organic Carbon, N, P2O5, K2O and Cd Content), Cadmium content in root, straw and grain of rice, Enrichment Factor (EF) and Translocation Factor (TF)of rice significantly decreased with increasing doses of cadmium in soil. Results obtained from the experiments also revealed that addition of biochar significantly increased these parameters of rice. In general, the application of biochar has shown the ability to reduce the toxic effect of cadmium. Top Keywords Biochar, Cadmium, Enrichment and Translocation factor, Rice. Top |
