OIL PALM NURSERY MANAGEMENT

Management of Oil Palm Nurseries 
1. Preparation nurseries. 
     Land with herbicides glyphosate spray dose of 1.5 to 2 liters / ha or mixed with 2,4 - diamine 0.5 l / ha     before shipping ground to nurseries. 
2. Soil:     
     Take the area of ​​non-oil palm, Top soil taken from the surface of structured soils 0-20 cm deep well that is free of pests and diseases (eg not from the area Ganoderma). Fertile land should be marked by the growth of ground cover that good. Soil should have good drainage reply (eg land free of standing water after watering). If only available clay, mixed with 20% coarse sand. 
3. Seeding one stage.
      Combine 1 ton of soil sieve with 3 kg of rock phosphate (or 50 kg dry POME) for charging 50 polybags large (60g equivalent RP or 1 kg per polybag large POME) Fill ± 20 kg polybags with soil completely. Stacking sequences consisting of 4 polybags per row with a distance of 10m between rows. Flush for 1 week and if necessary ground plus up ranged from 2 cm below the surface of the polybag
4. Breeding two stages 
     Fill small polybags with soil sieve. Add 20g of rock phsphate and mix evenly.Polybag meeting arranged in 10 rows long swath of 10m x 0.8m polybags 1200. The distance between the seed plot was 0.8m.It is advisable to use a wooden board 20-cm width around the seedlings to reduce the selection of breeds which lies alongside. 
5. Taking seed: 
     The seeds should be taken directly from the Center for Seeds by estate staff and the quality of the seed before packing. Nursery Assistants must ensure that the straps are still intact on the box when it arrived at the nurseries.
 6. Planting the seed:
      Plumula (end more smooth / slippery) must be above ground and covered with 1 cm. View. Do not remove the seeds from the box before it is ready for planting and put in place the box room of a shady or air-conditioned. Planting by the number "bref" (Reference Number Pollination) (1 cm above beans) 
7. Calculation of seed: 
     Before and after planting, these things must be noted below:
  • • The number of seeds received
  • • The number of damaged seeds
  • • The number of seeds infected with fungus
If the seeds are damaged / moldy more than 0.5%, report to the Central Seed seed seed as soon as possible and should be kept for inspection.Seeds infected with fungus, given pelakuan with Dithane 0.2% for 2 minutes apart and planted in place. These seeds are recorded when planted.After 2 weeks - 1 month planting, seed count is not growing. Report to the Central Seed when that failed to grow more than 2% and save it for review.Note also the seeds are exposed to:
  • • culling I at the age of 3 months,
  • • culling II at the age of 6 months
  • • culling III at the age of 9 months after planting.
8. Shade: 
     Generally not necessary. However, when very high temperatures and low humidity, place the "thatch / straw dry" surface poly bag and discarded after 2 weeks.
9. Mulch:
      If available, add a piece of palm shells or hay / dried weeds in the plastic bag to reduce evaporation, deter weed growth and prevent soil erosion when watering. 
10. Watering:
      In the morning and evening, pour about 1 liter of water for large polybag (or 150ml for small polybags), if the previous day's rainfall of less than 8 mm.
11. Manuring Schedule :
      Follow SOP palm fertilizer. 
12. Weeding:
      After planting, weeding outside and inside a polybag done manually. 
13. Growth Double / Triple:
      Leave the other strongest destroyed. 
14. Selection / Culling:
  • • Conducted by the Central Seed. Type of palm oil that will be attached culling.
  • • After the first culing (3 months) at one stage nurseries, thinning to 90cm x 90cm polybag triangle (78cm between rows).
  • • For the 2-stage nurseries, seedlings from small polybags transferred to polybags large 90cm x 90cm prepared triangular.
15. Collante: 
     If the percentage of seedlings with symptoms of high collante this is usually caused by a lack of watering. Because symptoms collante abnormal symptoms that are not genetic, it must be maintained collante seeds and watering plus.
 16. Pests and Diseases:
      If there is a pest or disease attack, immediately contact a Seed. Recommendations and chemical control will be attached..
