Fertiliser for Coconut and King Coconut Cultivation

The purpose of fertiliser application is to supplement soil nutrients like Nitrogen (N), Phosphorous (P), Potassium (K) and Magnesium (Mg), which are removed from soils over a period of time due to uptake by palms, runoff, leaching, erosion and uptake by weeds. Deficiency of these elements in the soil will inevitably result in a gradual decline of coconut and king coconut yield.

Basal Dressing at Planting

Soil used to fill planting holes should be mixed with the following. In addition, application of organic fertiliser such as dry cattle manure, goat manure and seasoned poultry manure (10 kg per planting hole) is beneficial.

Wet & Intermediate Zone	Dry Zone
Y.P.M - W 1.25 Kg	Y.P.M - D, 1 Kg
Dolomite 1 Kg	Dolomite 1 Kg

Rate of Application for Young Palms [ g / palm ]

6 months	800	650	500
1 year	1000	800	500
1 1/2 years	1000	800	500
2 years	1300	1100	500

3 years	1600	1350	500

4 years to bearing	2000	1600	500

Fertiliser should be applied in a circular pattern, 1 foot away from the base of the plant in the first 1 – 1 ½ years.
Distance of application from the base of the tree should gradually increase with growth.
Fertiliser should be applied at least once in six months.

Rate of Application for Adult Young Palms [ Kg / palm / Year ]

Soil condition	A.P.M - W - D (Wet & Intermediate Zones)	A.P.M - W (Dry Zones)	Dolomite
Soil Condition 1 Lateritic or quartizitic gravelly loams, Sands in coastal plain and river flood plains	3.3	3.0	1.0
Soil Condition 2 Deep reddish or yellowish loams in coastal areas and deep loams at foothills, alluvial loams in flood plains.	2.3	2.1	1.0

Application of 1.5 times the above rates is recommended for hybrid coconut, improved cultivar and high yielding palms (yielding more than 74 nuts/palm/year).
Fertiliser should be broadcast in the entire area around the base of the palm up to the distance of approximately 6 feet.
Application should be carried out annually.

Dolomite Application

Dolomite should not be mixed with fertiliser mixtures and should be applied separately as it reacts with urea in the mixture and releases Nitrogen and Ammonia. However, a time lapse between fertiliser and dolomite application is not necessary.

General Guide for Fertilizer Application

Fertiliser should be applied when the soil is moist.
Weeds in the manure circle should be slashed before fertiliser application.
The manure circle should be completely covered with material such as weed trash, dried fronds and husks as soon as application is complete.
On steep slopes, fertiliser should be applied in a semi circular shallow basin on the upper part of the slope.
The basin should be closed and well mulched after application.
Adult palms require application twice a year with each monsoon season and young palms four times a year to minimise the loss of nutrients due to leaching.
