Abstract
Abstract Critical land rehabilitation efforts in the forests areas are important activities to be undertaken. Dipterocarpaceae is a potential species to be developed in the restoration of degraded forest areas, one of which is Kapur Tanduk ( Dryobalanops lanceolata Burck.). This study aims to determine the influence of canopy opening factor, dose of manure, and environmental conditions (temperature, humidity, slope, and soil conditions) to the growth of D. lanceolata in research plots (KHDTK Haurbentes, West Java). The results showed that the different levels of canopy opening (71.34%, 37.91%) and the dose of manure (0, 2, 4 kg / planting hole) have no significant effect either single or interaction both to the increase in diameter and height of D. lanceolata . The Different levels of canopy opening in both areas resulted that different responses in the early days of growth, the degree of opening of 71.24% (open area) had a good response to the diameter growth while at the level of opening of 37.91% (under the shade) had high growth rate of plants. Thus, until the age of 6 months D. lanceolata has a good adaptability to the degree of canopy opening in between 37-72%. The environmental conditions in the research plots in KHDTK Haurbentes are suitable with the characteristics of the growing species so it can support the growth of D. lanceolata .
