| Abstract | To compare the target and non-target effects of two chemical-pesticides (chlorpyrifos and endosulfan) with that of a bio-pesticide (azadirachtin), Vigna radiata (mung bean) was grown in a randomized pot experiment with recommended and higher application rates of pesticides. Colony counts enumerating specific microbial populations, viz. fungi, Pseudomonas, nitrogen-fixing bacteria, and phosphate-solubilizing microorganisms, were performed. In addition, several plant growth parameters such as root and shoot lengths were also monitored. It was observed that the pesticides exerted a suppressive effect on different microbial communities under study in the initial 30 days period. The bacterial and fungal populations in chlorpyrifos treated plants increased thereafter. Endosulfan resulted in enhancement of fungi and nitrogen-fixing bacteria, although phosphate-solubilizing microorganisms were suppressed at higher application rates. Azadirachtin, which is gaining popularity owing to its biological origin, did not result in enhancement of any microbial populations; on the other hand, it had a deleterious effect on phosphate-solubilizing bacteria. This study is the first to evaluate the non-target effects of pesticides with a comparison between chemical- and bio-pesticides, and also stresses the importance of critical investigation of bio-pesticides before their wide spread application in agriculture. |

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.
