The Effect of Method and Germination Paper Substrate on Viability of Eucalyptus Pellita F. Mull Seed

Improper seed handling of Eucalyptus pellita will reduce seed quality, so as to improve the viability of the seed proper handling techniques are needed. To investigate the seed germination potency as a result of seed handling germination seed tests are needed. The purpose of this study was to examine the effect of germination method and paper substrate on the viability of E. pellita seeds. Seeds used in this study were from seedling seed orchard in South Sumatra, South Kalimantan, and Riau. Seed germination methods used in the laboratory tests were method of top paper and between paper tests, besides that, different papers were used such as: paper substrate namely straw paper, towel paper, filter paper, and newspaper. Factorial experimental design completely randomized was used. The results showed that: (1) the method of germination and paper substrate was significant (2) the best paper substrate and germination method was the method of top paper test with used media of newspaper (germination percentage 204 seedling /0.01 grams).

Growth of Nyamplung (Calophyllum Inophyllum L.) on Three Planting Patterns and Dose of Fertilizer on Sandy Beach Pangandaran, West Java

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.

Pertumbuhan Semai Cendana (Santalum Album Linn.) pada Beberapa Ukuran Kantung Plastik di Daerah Semiarid

Mortality of sandalwood plantings in the semiarid region is high (less than 50 %), due to poor quality. One of seedling of the alternatives to reduce this mortality is using optimal container size. The method is hoped to increase the growth and survival rate of sandalwood seedlings in the field. The objective of this study was to determine the effects of various sizes of seedling container on growth and to recommend the best polybag size for sandalwood nursery. The study was conducted in Complete Randomized Design method using container size of polybag (wide x length as main treatment) i.e.: 7 x 20 cm2, 8 x 20 cm2, 9 x 20 cm, 10 x 21 cm2, 11 x 22 cm2, 12 x 23 cm2, 13 x 23 cm2, 14 x 24 cm2, and 15 x 252 cm. Experiment consisted of 30 replications. The polybag was filled with the potting medium consisting soil, sand, and compost in volume ratio of 4:1:1 and sown with Alternanthera sp. as a primary host plant in all treatment. The results of the experiment proved that application of polybag size (7 cm x20 cm to 15 cm x 25 cm) had significant effects on height, diameter, dry weight total, top root ratio, quality index and survival of sandalwood seedling at six months old. The application of polybag size 15 x 25 cm2 (1080 mL) produced the best growth i.e. height (24.53 cm ), diameter (4.27 mm), dry weight total (1.86 g), top root ratio (0.54), quality index (0.28) and survival (92 %).
