About Potassium Deficiency
Potassium deficiency is the most common nutrient disorder in coconut cultivation. High demand for potassium during nut production causes older fronds to exhaust their reserves, showing severe yellowing and tip necrosis.

Prevention & Cure
Natural & Organic Methods
- Incorporate organic coconut husks, coir dust, and wood ash in a 2-meter radius basin around the trunk.
- Return composted crop residues and fronds back to the soil basin.
Chemical & Professional Control
- Apply Muriate of Potash (MOP) at 1.5–2 kg per palm/year, split into two doses (May-June and Sept-Oct).
- Ensure balanced nitrogen fertilisation, as excessive nitrogen worsens potassium hunger.
