- Produces 50–150 nuts annually, depending on care and conditions.
Lifespan:
- Productive for 40–50 years.
Nut Characteristics:
- Medium-sized, round green coconuts.
- Water content: 200–400 ml per nut.
- Sweet water with a balanced electrolyte profile.
Growth Requirements
Climate:
- Tropical climate.
- Ideal temperature: 20–35°C (68–95°F).
- Rainfall: 1500–2500 mm/year or availability of irrigation.
Soil:
- Well-drained sandy loam or alluvial soils.
- Tolerates a pH range of 5.5–8.0.
- Depth: At least 1 meter for healthy root growth.
Sunlight:
- Requires 6–8 hours of direct sunlight daily.
Water:
- Regular watering during dry periods.
- Avoid waterlogging, as it can harm the roots.
Planting Specifications
Seedling Selection:
- 8–12 months old seedlings with a strong root system and 5–7 healthy leaves.
Planting Distance:
- Spacing: 6 x 6 meters (20 x 20 feet).
- Plant density: 150–180 trees per hectare.
Pit Preparation:
- Dimensions: 60 x 60 x 60 cm.
- Fill pits with a mix of topsoil, compost, and organic manure.
Planting Time:
- Best during the monsoon season or when sufficient irrigation is available.
Care and Maintenance
Irrigation:
- Water young plants weekly.
- Mature plants require water every 10–15 days, especially during dry seasons.
Fertilization:
- Apply organic manure (10–20 kg/tree/year).
- Inorganic fertilizers (NPK 100:40:140 g/tree/year), divided into three doses.
Mulching:
- Use organic mulches like dry leaves or coir to conserve soil moisture.
Weeding:
- Remove weeds regularly to reduce competition for nutrients.
Pruning:
- Remove dead or diseased fronds and old flower stalks.
Pest and Disease Management
Common Pests:
- Rhinoceros Beetle: Use pheromone traps and neem-based pesticides.
- Red Palm Weevil: Regular inspection and pheromone traps.
- Leaf-eating Caterpillars: Biological control with natural predators.
Diseases:
- Bud Rot: Treat with Bordeaux mixture or copper fungicides.
- Stem Bleeding: Remove affected tissues and apply fungicide paste.
Preventive Measures:
- Ensure good drainage to prevent fungal infections.
- Maintain plant health through balanced fertilization and irrigation.
Yield and Productivity
Yield Per Tree:
- 50–150 nuts per year after maturity.
Economic Yield:
- Begins after 3–4 years of planting and peaks around 10–20 years.
Harvesting:
- For tender coconuts: Harvest at 6–7 months after flowering.
- For mature coconuts: Harvest at 11–12 months.
