Palm Trees

APPLICATION OF D.I. GROW FERTILIZER ON PALM TREES
NURSERY

  • Pre-Nursery (Nursery in small polybags, ± 3 months)
  • Basic fertilizer is still applied as the dosage recommended.
  • Apply D.I. GROW Green fertilizer as leaf fertilizer. D.I. GROW spraying is applied once every two weeks at a dosage of 25 cc/15 liters of water (1 lid of jerry can/1 spray tank of 15 liters). Spray evenly on the leaves and stems of the palms. The first spray applied when the nursery transplants (seeds) are above 1 month old.
  • The spraying activity is applied before 09.00 a.m. or after 04.00 p.m.
  • In case of pest/disease infection, D.I. GROW fertilizer may be applied in a mixture of pesticide/fungicide.
  • Main Nursery (Nursery in big polybags, ± 9 months)
  • Basic fertilizer (NPK) is still applied as the dosage recommended.
  • Apply D.I. GROW Green fertilizer as leaf fertilizer. D.I. GROW spraying is applied every three weeks with a dosage of 3 cc/liters of water (2 lids of jerry can/1 spray tank of 15 liters). Spray evenly on the leaves and stems of the palms.
  • The spraying activity is applied before 09.00 a.m. or after 04.00 p.m.
  • In case of pest/disease infection, D.I. GROW fertilizer may be applied in a mixture of pesticide/fungicide.
  • Green D.I. GROW required for each spraying per Ha is ± 1.5 liters.

IMMATURE PLANTS (IP), BELOW 3.5 YEARS OLD
  • Basic fertilizer (NPK) is still applied, yet reduced 30% of the dosage recommended.
  • Apply D.I. GROW Green fertilizer as leaf fertilizer. D.I. GROW spraying is applied every 2-3 months with a dosage of 10-12 cc/liters of water (150-180 cc/1 tank of 15 liters of water). Spray evenly on the leaves and fruits of the palms.
  • The spraying activity is applied before 09.00 a.m. or after 04.00 p.m.
  • In case of pest/disease infection, D.I. GROW fertilizer may be applied in a mixture of pesticide/fungicide.
  • Green D.I. GROW required for each spraying per Ha (140-150 trees) is ± 2-3 liters.

MATURE PLANTS (MP), 3-5 YEARS OLD
  • Basic fertilizer (NPK) is still applied, yet reduced 30% of the dosage recommended.
  • Apply D.I. GROW Green fertilizer as leaf fertilizer. D.I. GROW spraying is applied every 2-3 months with a dosage of 16 cc/liters of water (250 cc/1 tank of 15 liters of water). Spray evenly on the leaves and fruits of the palms.
  • The spraying activity is applied before 09.00 a.m. or after 04.00 p.m.
  • In case of pest/disease infection, D.I. GROW fertilizer may be applied in a mixture of pesticide/fungicide.
  • Green D.I. GROW required for each spraying per Ha (140-150 trees) is ± 4 liters.

APPLICATION OF D.I. GROW FERTILIZER THROUGH INJECTION TECHNIQUE ON PALM TREES
Step-by-step application:
  • Requirements: The lowest midrib height from the land surface is minimally 1 meter.
  • Equipment : Prepare for the following equipments: driller with a diameter of 2.2 mm or 2.5 mm, PVC pipe with a diameter of ½ inch or ¾ inch, sprayer.
  • Application: Make a drilling hole on the plant stem with ±10 cm in depth, the drilling height from the land surface is 60-80 cm from the land surface, and the drilling position is oblique for 450.
  • Cut the pipe with 20 cm in length, and enter the pipe into the drilling hole with 10 cm in depth (10 cm inward, and 10 cm outward).
  • Make a mixture of D.I. GROW with a concentration of 750 cc – 1000 cc D.I. GROW + 15 liters of water (1 spraying tank), mix well, and enter the mixture into the pipe, then close the pipe's hole in order to avoid insect or fungus/disease entry. Such mixture can be applied for 150-200 trees (1 Ha of palm trees).
  • The interval of application is each 3-4 months to reach a high result and stability of production.

D.I. GROW FERTILIZER TESTING ON PALM TREES
1. Balancing the Ratio of Male and Female Flowers
Steps:
  • Choose palms with more male flowers than the female flowers, or mostly producing female flowers.
  • Dissolve Urea 500 grams +D.I. GROW Red 200 cc + 10 liters of water per tree.
  • Flush the solution around the plate of palm trees, the range from the stem tip of the palm tree is 0.5 meter.
  • Then, make solution of D.I. GROW Red again with a concentration of 250 cc + 15 liters of water (1 spraying tank). Spray the solution on male flowers, stems and leaves evenly wet.
  • Within 15 days, the male flowers will fall out and be easy to be taken out, and then female flowers will grow on the new midrib. When the trees are high enough, the D.I. GROW fertilizer application is implemented by injection.

2. Enhancing the Quality of Palm Fruit
Spray D.I. GROW Red on the palm fruit evenly with a dosage of 250 cc + 15 liters of water (1 spraying tank). Within 30 days, the palm seed will grow bigger, shinier and the weight is increasing about 30%-50%. Therefore, it is recommended to spray the palm fruit with such dosage 30 days before being harvested.
