A three-month-old composted municipal solid wastes (MSW) was applied as organic fertilizer at different rates of application to seedlings of three selected endemic tree species, Anis (Clausena anisum-olens (Blanco) Merr.), Banilad (Sterculia comosa Wall. = S. philippinensis Merr. and Cebu cinnamon (Cinnamomum cebuense). The seedlings were collected from Tabunan forest, Cebu, Philippines. Using 100% ordinary soil as Control, the varying levels of MSW application were namely, 25% Compost (Treatment 1), 50% Compost (Treatment 2), 75% Compost (Treatment 3) and 100% Compost (Treatment 4). In seven months of growing time, change in growth was determined by subtracting final seedling size with initial seedling size. Size parameters were height and basal area. Number of shoots was also observed. The results of the study proved that application of MSW on ordinary soil can circumvent limiting factors enabling endemic tree species to grow faster in nutrient poor soils and can be used as reforestation species instead of exotic tree species. The study also showed that response for the same set of MSW application rates varied with species.
