The accumulation of Cr in soil is a major concern because of its possible phytotoxicity or increased movement of metals into food chain and the potential for surface and ground water contamination. Excessive metal accumulation in contaminated soil can result in decrease in soil microbiological activities, soil fertility and overall soil quality which may lead to reduction in yield. With Three levels of chromium concentration (0, 25, 50 ppm) with and without organic amendments like Biochar, Poultry Manure and sewage sludge a pot culture experiment was conducted taking paddy as a test crop with an objective to study the remediation effect of these organic amendment on Chromium toxicity by assessing different growth parameters and yield attributes of Rice plant. Results shows that there is a significant increase in the growth parameters like plant height, number of tillers/hills, productive tillers/hill, number of grains/panicles, chlorophyll content, panicle length, test weight, straw yield, grain yield and harvest index with application of Biochar, Poultry manure & Sewage sludge. Hence organic amendment like Biochar, Poultry manure and sewage sludge play a great role in remediation of chromium contaminated soil and increase ability of rice crop to withstand Cr toxicity up to 50ppm.
