Abstract: Contamination of chromium is considered a serious environmental pollutant due to wide industrialization. A pot experiment was conducted in net house of Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during 2015-16 to study the effect of FYM and vermicompost on soil physico-chemical properties in chromium contaminated soil in rice. The Physico-Chemical properties of soil is based on various parameters like pH, Electrical Conductivity(EC), Organic Carbon, Available Nitrogen (N), Available Phosphorus (P2O5) and available Potassium (K2O).Five levels of chromium viz. 0, 20, 40, 60 and 80 ppm with and without vermicompost @ 5 ton ha-1 and farm yard manure @ 10 ton ha-1 were taken. Results indicated that the organic carbon, available NPK was recorded highest with the treatment Cr0+ VC followed by treatment Cr0+FYM and then Cr0 i.e., not- amended the soil. Rice crop can withstand up to 80 ppm of chromium with vermicompost and can tolerate up to 60 ppm with FYM. Hence, physico-chemical properties of post-harvest soil of rice contaminated with chromium are more effectively increased with application of vermicompost and FYM application and reduce the risk of health hazards for human beings and animals.
