The study was conducted to evaluate the effects of the two organic concoctions namely Indigenous Microorganism (IMO) and Oriental Herbal Nutrient (OHN), vermicast and inorganic fertilizer on the growth performance of Bakan (Litsea philippinensis Merr.) seedlings. The study was conducted at the Forest Resource Development Division (FRDD) Nursery using Completely Randomized Design (CRD) with six (6) treatments replicated three (3) times. The variables evaluated include root collar diameter, seedling height, number of leaves, percent survival, and disease severity. Results show that the application of complete fertilizer and organic concoctions (IMO and OHN) demonstrated a significant increase in height, root collar diameter, and percent survival of Bakan seedlings compared to the control. However, the effects on the number of leaves, percent survival, and disease severity of leaf spot and leaf blight were statistically not significant. Moreover, the results also show that the two organic concoctions outperformed the inorganic fertilizer in terms of the height of the seedlings. Indeed, it is concluded that the two concoctions used could be good substitutes or alternatives to inorganic fertilizer. Hence, the use of these concoctions may set an as good example to indicate that organically-based products will yield relatively comparable results with inorganic fertilizers.
