  2. 2. SCENARIO 2 Oh no! It cannot suit….. A traditional farmer from the land of Arab was really interested in rambutan fruits that the ate in Malaysia. Thus he tried to plant this rambutan tree near his cactus nursery at his hometown. He took good care of his rambutan trees just as he did to his cactus plant.
  3. 3. Facts Ideas Learning Issues Action plans 1. A traditional farmer from Arab land interested in rambutan tree that he ate in Malaysia 2. He tried to plant rambutan tree near his cactus nursery at his hometown 3. He took good care of his rambutan trees just as he did to his cactus plant 4. Two years later, the rambutan trees are found dead 1. The farmer has no knowledge about the rambutan tree 2. He thought all the plant must be take care in the same way 3. Unfavourable land in Arab 4. Temperature in Arab is too high to plant the rambutan tree 5. The rambutan tree has disease 6. Not enough water supply 7. The farmer do not give any fertilizer to rambutan tree 8. Rambutan tree has short life cycle 9. Rambutan tree was attacked by parasite 10. Different types of root.; cactus has water storage root while rambutan has fibrous root 1. Why the temperature in Arab not suitable with rambutan tree? 2. How to plant rambutan tree? 3. Does rambutan tree need fertilizer? 4. What is the difference between root in rambutan with root in cactus ? 5. How long rambutan trees can live without water? 6. What is the knowledge that farmer need to know about the rambutan trees? 1. Research in internet 2. Find journal about rambutan tree in library 3. Ask botanist about rambutan tree and cactus 4. Ask lecturers 5. Construct an experiment 6. Ask my pen-pal (Nawaf) from Arab in facebook
  4. 4. 2. How to plant rambutan tree? firstly, prepare your planting materials. Select well-developed seeds from mature/ripe fruits of the recommended varieties or selections. Remove mucilage from the seeds by rubbing them with fine sawdust, ash or old newspaper. Germinate the seeds immediately after extraction in light loamy soils or in germination beds made up of sawdust.
  5. 5. Germinated seeds should be ready for potting in 24 days after sowing. Transfer them to perforated plastic bags containing garden soil and place them in nursery shed. Water the seedlings after transferring. Then, water every 2-3 days as the need arises. The rootstocks would be ready for asexual propagation in 8-12 months.
  6. 6. 4. What is the difference between root in cactus with root in rambutan ? Rambutan has fibrous root while cactus has water and food storage root which is a tough layer of tissue surrounding the stems of cacti and special substances within the storage cells located inside the stems further reduce loss of water.
  7. 7. Most fruit trees need water to fruit no matter how fertile your soil is. During the dry months, make sure that the trees don’t suffer from drought. Irrigate the trees. During the rainy months, however, make sure the orchard is properly drained. The dry season should not last over 3 months.
  8. 8. The tree does best on deep, clay-loam or rich sandy loam rich in organic matter, or in deep peat. It needs good drainage. It is recommended that the trees be planted at least 33 ft (10 m) apart each way, though 40 ft (12 m) is not too much in rich soil. If the trees are set too close to each other, they will become overcrowded in a few years and production will be seriously affected. .
  9. 9. Rambutan is a tropical fruit tree best grown in the temperature range between 22C to 35C, with 2000 to 3000 mm of well distributed rainfall. It is intolerant to frost, especially during the juvenile stage. Mature trees may survive a brief period of temperatures as low as 4C but with severe defoliation. It prefers clay loam soil, pH 5 to 6.5, but can be grown in a wide range of soil types, even ones with poor drainage, but not water-logged. Flower induction is independent from photo period, but can be induced by water stress. Low relative humidity and wind during fruiting could cause excessive moisture loss from fruit spinterns and result in poor fruit appearance.
  10. 10. Rambutan trees should be sheltered from strong winds which do much damage during the flowering and fruiting periods.
