Abstract: The dry leaves of <i>Psidium guajava</i> Linn., <i>Ficus benghalensis</i> Linn., <i>Codiaeum variegatum</i> Linn., <i>Polyalthia longifolia</i> Sonner., <i>Eucalyptus citriodora</i> Hook., <i>Caesalpinia pulcherrima</i> Linn., <i>Syzygium cumini</i> Linn., <i>Artocarpus heterophyllus</i> Lamk., <i>Musa paradisiaca</i> Linn., <i>Plumeria rubra</i> Linn., <i>Litchi chinensis</i> Gaertn., <i>Pinus insularis</i> Endl., <i>Elaeocarpus sphaericus</i> Gaertn., <i>Bombax ceiba</i> Linn., <i>Streblus asper</i> Lour. and <i>Dalbergia sissoo</i> Roxb. were converted to vermicomposts in about 5 to 8 months while those of <i>Mangifera indica</i> Linn., <i>Terminalia chebula</i> Retz., <i>Lagerstroemia speciosa</i> Linn. and <i>Tectona grandis</i> Linn. took about 10 months. However, <i>Leucaena leucocephala</i> Lamk. leaves took only 2 months to become vermicompost. These vermicomposts contained: N, 0.9 to 1.9; P, 0.5 to 1.2; K, 0.9 to 2.5; Na, 0.8 to 3.5; Ca, 0.9 to 4.9 and S, 0.9 to 2.2%. The vermicompost of <i>Bombax ceiba</i> flowers produced in 3.5 months contained: N, 1.2; P, 0.6; K, 1.8; Na, 1.4; Ca, 0.4 and S, 0.9%. Nutritional status of these vermicomposts varied with the variation of tree species. This information would motivate farmers for vermicomposting of dry leaves instead of burning.
