Abstract

The growth rate of Paraserianthes moluccana is effected by the planting medium quality. Biochar is a soil-improving agent that could improve soil quality. This study aimed to determine the effect of biochar made from meranti wood (Shorea spp.) by pyrolysis temperature at 400°C and 600°C and dose at 0 ton/ha, 25 ton/ha and 50 ton/ha factors through the growth rate of P. moluccana. The P. moluccana was planted within 2x2 m in the field. The size of planting holes was 100 x 60 cm, the biochar was placed at a depth of 100 cm to 20 cm, then it was covered with soil so that the root did not interact directly to the biochar. This research used 6 months old P. moluccana seedling, and was planted in field demplot for 8 months. The research used the Split Plot experimental design with 5 treatments and 7 repetitions. Data analysis used Analysis of Variance (ANOVA) and Least Significance Different (LSD). The effect of biochar could be seen since the 4 th month of plantation. The results showed that biochar with a dose of 25 ton/ha and pyrolysis temperature of 600°C had a very significant effect on the increment of height and significant on diameter steam increment of P. moluccana; increased the rate of stem height 22.6% and stem diameter 23.6% faster than the control. Further research related to the dynamics of P. moluccana growth with a longer time is needed because the physical properties of biochar change over time.
