HARVESTING
Harvesting is done throughout the year. Trees
begin to yield fruit in 5-6 years on good soils, more
likely 7-9 years, and reach full bearing in 12-13 years.
The time from fruit set to full maturity is about 8-10
months; 12 months from setting of female flowers. The
fruit should be harvested fully ripe for making copra
and desiccated coconut. Drinking nuts should be picked
earlier, at about 7 months. For coir they are picked
about 1 month short of maturity, so that husk will be
green. The nuts may be harvested by skilled climbers
or may be cut from the ground, using a knife attached
to a long pole. This is the cheapest method. With pole,
a man can pick from 250 palms in a day, by climbing,
only 25 palms. In some areas nuts are allowed to fall
naturally and collected regularly.
Post-Harvest Handling System
Successful storage can be achieved for two to three
months with the correct grading and handling procedures.
Harvesting
Dry coconut husks should be taken from the tree and
dehusked, removing the flare.
Export Grading and Packing
All grading and packing should be carried out in the
field as opposed to transporting the nuts to a centralized
packing facility. Size grading is required with outgrowing
being made for incorrect sizes, damaged and diseased
nuts. Dry coconuts are loose packed into woven plastic
sacks in counts of 20 per sack. Full telescopic two-piece
fiberboard cartons may be used when financial returns
warrant the additional cost.
Storage and Transportation
Dry coconuts can be shipped successfully by sea in reefer
or dry containers for up to three weeks. Storage temperatures
of 12 C will assist in quality maintenance. Where possible
palletized systems should be used to reduce the potential
for cracking of nuts.
Potential Post-Harvest Losses
Losses in coconut are mainly as a result of cracking
due to poor or inappropriate handling. Spoilage can
occur due to softening and disease infection of the
eyes. This can be avoided by careful grading, preventing
damage to the eyes and maintaining the coconuts under
suitable storage conditions.
Coconut Specifications
Characteristics
Clean and round
Size:
· Minimum weight: 750 g
· Maximum weight: 850 g
Condition :
· Uniform, fresh, no excessive hairs;
· Free from splitting and cracking;
· No sunken eyes or fungal infection.
Market Requirements
Uniformly round, within the stated size specifications,
preferably packed in cartons.
Handling in Importing Countries
Maximum marketing period can be achieved by storage
at 12 C and careful handling to prevent cracking. Coconuts
can be stored with other products without any detrimental
effects.
Storage
Coconut may be stored at temperature of 0-1.5C with
relative humidity of 75% or less for 1-2 months. In
storage, they are subject to loss in weight, drying
up of nut milk and mold. They may be held for 2 weeks
at room temperature without serious loss.
