Abstract | Pot experiment, in which vermicompost enriched with high Cu and Zn contents was applied in aqualf soil to simulate soil metal accumulation from vermicompost application, was conducted to study the effect of vermicompost application on growth of Sorghum Hybrid Sudangrass and Euchlaena Mexicana Schrad as well as their Cu or Zn uptake and soil characteristics. The results showed that shoot growth was improved for the two pastures, while it was significantly inhibited for the root growth of Euchlaena Mexicana Schrad with increasing heavy metal pollution from vermicompost application. Both Cu or Zn contents in shoot or root of Sorghum Hybrid Sudangrass and that in Euchlaena Mexicana Schrad increased after vermicompost application, especially, Cu content in roots of Sorghum Hybrid Sudangrass increased significantly with increasing heavy metal pollution from vermicompost.application In addition, Correlation analysis showed that Cu or Zn contents in two pastures were positively related to acid-extractable and reducible Cu or Zn fraction. So, continuously consecutive application of vermicompost enriched with high Cu and Zn content could contribute to the accumulation of exchanged and reducible Cu or Zn content in soil and pose a potential threat to the plant system. |

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.
