Abstract : Soil analysis of mango orchards of Dehradun yielded 26 genera of bacterivore and fungivore nematodes. Bacterivore nematodes were dominant group comprising 80.76% while, fungivore comprised 19.23%. In terms of taxonomic diversity among the 26 genera identified, 51% belonged to order Rhabditida comprising 13 genera, followed by Araeolaimida (19.2%) with 5 genera, Tylenchida (11.5%) with 3 genera, Aphelenchida (7.6%) with 2 genera and the orders Chromadorida, Monhysterida and Alaimida comprising 3.8% each with one genus each. The diversity indices such as the Shannon-Weaver and Inverse Simpson showed that this site has a high nematode diversity of 2.78 and 12.7 respectively. Nematode Channel Ration (NCR) showed 0.862 which shows that bacterial decomposition pathway is dominant in the area.
