| Abstract | The potential of vermicompost, elemental sulphur, Thiobacillus thiooxidans and Pseudomonas putida for phytoremediation is well known individually but their integrated approach has not been discovered so far. The present work highlights the consideration of so far overlooked aspects of their integrated treatment by growing the ornamental plant, Gladiolus grandiflorus L in uncontaminated and sewage-contaminated soils (sulphur-deficient alluvial Entisols, pH 7.6-7.8) for phytoremediation of cadmium and lead under pot experiment. Between vermicompost and elemental sulphur, the response of vermicompost was higher towards improvement in the biometric parameters of plants, whereas the response of elemental sulphur was higher towards enhanced bioaccumulation of heavy metals under soils. The integrated treatment (T7: vermicompost 6g and elemental sulphur 0.5gkg(-1) soil and co-inoculation of the plant with T. thiooxidans and P. putida) was found superior in promoting root length, plant height and dry biomass of the plant. The treatment T7 caused enhanced accumulation of Cd up to 6.96 and 6.45mgkg(-1) and Pb up to 22.6 and 19.9mgkg(-1) in corm and shoot, respectively at the contaminated soil. T7 showed maximum remediation efficiency of 0.46% and 0.19% and bioaccumulation factor of 2.92 and 1.21 and uptake of 6.75 and 21.4mgkg(-1) dry biomass for Cd and Pb respectively in the contaminated soil. The integrated treatment T7 was found significant over the individual treatments to promote plant growth and enhance phytoremediation. Hence, authors conclude to integrate vermicompost, elemental sulphur and microbial co-inoculation for the enhanced clean-up of Cd and Pb-contaminated soils. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
