Nyamplung (Calophyllum inophyllum L.) is one of the new alternatives of biofuels materials in the world. Hitherto, the information on the cultivation and processing techniques  is very limited. This study aims to   find out the growth of nyamplung on some cropping patterns on sandy beach Pangandaran in 4 (four) years. The experimental design  used in this study was split plot design. The main plots were  cropping pattern: agroforestry nyamplung, nyamplung monoculture and nyamplung + pandanus,  and the subplot  were fertilizer doses:  (1) no fertilizer (control), (2) 5 kg of organic fertilizer + 100 gr/plant NPK and (3) 10 kg of organic fertilizer + 200 gr/plant of NPK fertilizer. Each combination treatment consists of 25 plants that were repeated 3 times , so that the total number of plants observed were 675 plants. The growth parameters observed: survival rate, height, diameters and number of branches of plant until 4 years. The results of this study showed that the interaction of  treatments were statistically not significant. The growth of the plants  was significantly affected by cropping pattern and fertilization. The Agroforestry pattern produces the highest survival rate and growth that is 97.33% with an average height of 220 cm and an average diameter of 5.08 cm. Recommended fertilizer doses are  5 kg of  organic fertilizer for base and 100 grams of advanced fertilizer NPK  twice a year.
