Study on the Effect of Organic Fertilizer Application on Biomass of Orthosiphon Stamineus (Misai Kucing) at the Nursery of Universiti Putra Malaysia (UPM)


Medicinal and Aromatic Plants Seminar (MAPS 2008)

In Malaysia, research and development on medicinal plant species grows rapidly. Most species were tired and found to have commercial value. Orthosiphon stamineus is one of these species considered with commercial potential. To produce high quantity and quality O. stamineus stock, silviculture management is very important. This research was conducted at the nursery of Faculty of Forestry, Universiti Putra Malaysia. This research was to determine the best fertilizer type, rate and the best soil combination used for producing high quality O. stamineus planting stocks. Different soil combinations which was top soil, sand and peat soil was applied in this study. A total of 72 samples of stem cutting taken from mature mother plant were observed on the growth performance. This consisted of height, diameter, number of leaves, branches and twigs. These were conducted within five months. After five months, all samples were cut into three parts, roots, stem and leaves. Wet weight for all the samples was recorded and they were dried in the oven at 63ÂșC until the constant weight was reached. Biomass was calculated using mean dry weight of sample and analysed using ANOVA 2. The study showed that palm oil mill effluent (POME) produced the highest value of biomass and the best growth performance compared to chicken dung. For soil combination, ratio of 2:2 produced the highest value of biomass and best growth performance compared to other ratios.
