Smart Nutrient Management for Arecanut Farmers
Importance of balanced nutrition in Arecanut farming.
Common Nutrient Deficiencies in Arecanut
- Nitrogen: Stunted growth, pale leaves
- Potassium: Leaf tip burn, reduced nut size
- Magnesium: Yellowing between leaf veins
- Boron: Button shedding
Causes of Nutrient Deficiencies
Poor soil health, waterlogging, imbalanced fertilization
Right Fertilizer Plan:
- Apply 100:40:140 g NPK per palm/year for adult palms.
- Split doses: 1st year (⅓), 2nd year (⅔), 3rd year (full).
Dealing with Deficiencies:
- Magnesium: 1–2 kg MgSO₄/tree/year
- Copper: 0.5% CuSO₄ foliar spray
- Zinc: 0.5 kg ZnSO₄/tree/year
For Yellow Leaf Disease:
- Apply 100:40:200 g NPK + emphasize Potassium
- Add sulfur-based fertilizers for 100g sulfur/tree
Soil Testing & Custom Plans:
Customize inputs based on local soil health.
Conclusion:
Nutrient balance is key for better yield and sustainable farming.
