Sablot known as Litsea glutinosa Lour. C. Rob., also known as Litsea sebifera is a medium sized woody tree, evergreen, 20-25 meters high with cream flowers usually blooming on January to February with fruit diameter of 10-15 mm. It reaches 20-30 cm in diameter. It has round stem, straight, small branch position. Outer bark is slight yellow with aroma. Simple leaf is found in Litsea. The leaf is 12-18 cm long, 3-4 cm wide, sharp head, leaf stem is wedged-shaped, two flat faces. It thrives on lateritic and basaltic soil. This research aimed to determine the growth of Litsea glutinosa using different types of planting stocks. It was also geared towards the determination of the early growth performance of the different planting stocks potted in four (4 ) soil media. And finally, it aimed to recommend the most appropriate nursery propagation techniques for the conservation of Litsea glutinosa. Seed germination was earliest after planting in a clay loam type of soil at 60% germination viability. Propagating the stems directly into the soil did not grow buds. Soaking them for two days and transferring them into the soil gave growth but unable to sustain the buds. No roots appeared. It took lesser number of days to propagate the basal cuttings than the apical stem cuttings under the sun. There were more buds grown in the basal stem cuttings. The growth of sablot in terms of height was highest using the clay loam type of soil. Only clay loam and sandy loam were significantly different from each other in the sablot height. Among the four soil types, clay loam showed the most number of leaves, and there were no significant differences on the number of leaves grown in all the soil types. The growth of sablot in terms of length of leaves was longest using clay loam. There was a significant difference in the length of leaves to the different soil types. The growth of sablot in terms of width of young leaves was widest in clay loam but shortest in sandy loam. The lowest length of old leaves, which were located at the lower portion of the plant was measured in sandy loam . There was no significant differences on the width of sablot young leaves in different soil types. Although there was a significant difference in the width of old leaves planted in four soil types. Leaves grew almost constant by its width but grew fast by its length.
