Abstract


Kilemo (Litsea cubeba L. Persoon) is the one of plant which cultivated as a medicine plant, such an essential oil. This plant harvested at the tip of leaves and the leaves, therefore the management include pruning and fertilizing. This research was aimed to observe the effect of pruning and fertilizing toward population of rhizosphere communities on kilemo (Litsea cubeba L. Persoon). Pruning was practiced on to kilemo after 2 years and four fertilizing treatments i.e control (without fertilizing), NPK fertilizer, microfertilizer and compost,were applied on to the plant with pruning and without pruning. Results of this research showed that pruning was able to decrease population of Azotobacter, P solubilizing microorganism (MoPP), cellulose solubilizing microorganism (MPS). Pruning with fertilizing NPK treatment also decreased population of microorganism. Furthermore, giving organic fertilizer was able to increase population of Azotobacter microorganism and P solubilizing microorganism (MoPP). Meanwhile, microfertilizer only increased population of cellulose solubilizing microorganism (MPS).
