One of the factors that contributed to the success of restoration activities is the quality of the planting stocks used in the planting operations. At present, the use of indigenous species for planting is now being encouraged because of problems met in utilizing exotic species. In the Philippines, there are many indigenous and endangered species that are promising for restoration and agroforestry but they are seldom utilized. Among the list of species is ipil (Instia bijuga Colebr.). Ipil is also classified as vulnerable and need immediate protection and conservation. To fast tract the activity, fertilization of macropropagated ipil seedlings was conducted for better seedling quality. Specifically, the study aimed to determine if there are significant differences on the growth of ipil when applied with different selected fertilizers and to determine which fertilizer will enhance better growth of ipil in the nursery. Successful propagation of ipil using stem cuttings was achieved and fertilization studies obtained significant results. Macropropagated ipil was fertilized using Rhizo-N, Mykovam, urea, ammonium phosphate, complete (14-14-14) and complete (13-13-13) slow release fertilizer. The results of the study revealed significant differences on shoot length, stem diameter and oven dry biomass of macropropagated ipil seedlings over that of the untreated ipil seedlings. Best growth was attained using complete (13-13-13) slow release fertilizer and complete (14-14-14) fertilizer. However, application of complete fertilizer at 0.50 g per seedling in the nursery is preferred over the other considering cost.
