Druce} Growth in Different Compositions of Planting Medium and Level of ShadingABSTRACTThis research aimed to determine the effects of various compositions of planting medium and level of shading on the vegetative growth of the pitcher plant (Nepenthes mirabilis (Lour.) Druce). The experiments were arranged in a split plot arrangement on randomized blok design. The main plot was paranet shading (0%, 25%, 50%, 75%), and the sub-plots were planting medium compositions (cocopeat : rice husk charcoal (1:0) (1:0), cocopeat : rice husk charcoal (0:1) (0:1), cocopeat : rice husk charcoal (1:1) (1:1), cocopeat : rice husk charcoal (1:2) (1:2), cocopeat : rice husk charcoal (2:1) (2:1)). Increased shading levels from 0% to 75% caused N. mirabilis plants to be shorter and rosetted, with larger leaf surface area and more leaves and pitchers, but with smaller-sized pitcher. Nepenthes mirabilis which were planted in 1:1 medium showed have more leaves, and pitchers, larger pitchers, greater leaf surface area and longer roots, compared with those planted in 1:2 medium. However, the number of leaves and root length of plants in 1:1 medium was not significantly different to those in 1:0 and 2:1 medium. Pitcher size of N. mirabilis planted in 1:1 medium was not significantly different to those planted in 1:0 and 0:1 medium. The number of pitchers and leaf area of N. mirabilis planted in 1:1 medium was not significantly different to those planted in 0:1 and 2:1 medium. The pH level of 1:0 medium was lower than 0:1 medium at different levels of shading.Key words : Nepenthes mirabilis (Lour.)
