Abstract
Light is the most important physical factor for controlling the growth and development of plants. A preliminary study was done to determine the effects of different relative light intensity RLI and organic fertilizers on the growth of Orthosiphon stamineus Benth at the nursery of School of International Tropical Forestry. Randomized Complete Block Design RCBD was used. There were three different rates of light intensity used 70 shading 50 shading and 0 shading and different types of organic fertilizers which were chicken dung cow dung and empty fruit bunch EFB of oil palm. Two different ratio rates between normal topsoil sand and organic fertilizer were applied in this study 3:2:1.5 and 3:2:0.5 respectively. Relative Height Growth Rate RHGR was used to quantify growth rate.There were significant differences in rates used in O.stamineus seedlings between medium ratio 3:2:1.5 and 3:2:0.5 p0.05. The values indicated that fertilizer treatment was significantly different p0.05 across the three fertilizers used excluding control treatment. The Relative Light Intensity also showed a significantly different mean values among the treatments at p0.05. Fifty percent RLI was better for optimum growth of O.stamineus compared to 100 and 30 RLI. Chicken dung improved growth of O. stamineus followed by EFB oil palm and cow dung..
