Honeydew Melon Production
melon is one of the more expensive and in demand fruit vegetables.
It is an annual crop under the family Cucurbitaceae. It belongs
to the melon group Cucumis melo var. inodorus generally called
the winter melons, which include the smooth-skinned green-fleshed
Persian, the yellow-skinned, green-or white-fleshed casaba and
the dark green, wrinkled-skin and pink-fleshed Crenshaw. The
other group is C. melo var.cantalupensis, the cantaloupes or
on honeydew melon are lacking as its production is highly specialized.
In 1997, production area of honeydew melon covered 7 ha; melon,
893 ha; and muskmelon, 1033 ha.
and Nutritional Value
fruits are eaten fresh. It can be canned, dehydrated or made
into juice. Immature fruits may be used in salads, cooked or
pickled. Seeds are a dietary source of unsaturated vegetable
oil and protein, and may be roasted and eaten like watermelon
Honeydew melon is rich in
sugars, vitamins and minerals. The edible portion of the mature
fruit is about 45-80%. Each 100 g edible portion contains:
Vitamin B2 0.02
Vitamin C 6-60
Energy Value 75-220

And Soil Requirements
the Philippines, honeydew melon can be grown from low to mid
elevations. Bulk of production is in the low, flat areas during
the dry season. Melons, however, can be grown throughout the
year even in unprotected conditions.
Honeydew melon grows best in clay loan to clayey soils with a
pH of 6.0-6.8. During the dry season (Nov.-April), paddy soil
with ample irrigation water is best. During the wet season, sloping
areas for adequate drainage are preferred. Select areas, which
have not been planted to melons or related crops in the last
the area at least one month before transplanting. Plow and harrow
twice, pulverize the soil and remove plant debris.
Prepare 20-30 cm high and 1-m wide adjacent plots beds for furrow
irrigation. The set of adjacent plots should be 3-4 m apart depending
on variety. This will be the vine-crawling area.
1-2 kg well-decomposed animal manure per linear meter of beds.
Apply ½ of N and K requirements and all of P based on
soil analysis. In the absence of soil analysis, use NPK recommendations.
Soil granular insecticides may also be applied.
m-wide plastic mulch with silver and black finish. Roll out the
plastic, silver side up. Secure the sides with soil. It is best
to apply plastic mulch around midday when the temperature is
high to structure the plastic mulch well
| Trellised. Prepare raised beds 20-30 cm
high and 1.0-1.2 cm wide spaced 0.5-0.75 cm apart. Apply the
same rates of fertilizer and animal manure as the non-trellised
set-up. Use the plastic mulch.
growing medium is a mixture of equal parts garden soil, manure
or compost and rice hull charcoal. Soil sterilization is optional.
Drench with Captan, if necessary.
nursery trays with 60-100 holes per tray. Water first before
sowing. Sow one seed per hole pointed end first. Condition the
seeds before sowing by soaking in water for 30 minutes. Mulch
under partial shade or net until germination.
Water daily or as needed. Spray foliar fertilizer and fungicides
(Mancozeb) once a week. Spray insecticides if necessary. Harden
the seedlings 3-5 days before transplanting.
is best top transplant during the afternoon. Make holes spaced
0.4-0.5 m apart on the plastic mulch with a pointed stick or
hot can. Drench the holes with Captan and transplant one seedling
per hill. Water again after transplanting. Allow about 10% extra
seedlings for replanting.
is recommended during the wet season and under plastic. Vertical-and-A
frame type of trellis may be used. A nylon trellis net can be
used to minimize labor cost.
melons require abundant supply of water than most crops. Furrow
irrigation to field capacity should be done every 3-4 days. During
fruit setting to enlargement, it is best to keep the soil moist-wet
until two weeks before harvest. Erratic water supply results
to deformed fruits and increase crackling.
rate initially depends on available soil nutrients followed by
plant condition. Too much N will result to very vigorous but
susceptible plants. Regulate N especially during the wet season.
Side-dress 1: 1 urea (46-0-0) and muriate of potash (0-0-60)
at 10-20 g per hill every two weeks. Decrease N at flowering.
During fruiting, apply more K but always with at least 10% N
to enhance K adsorption. Potassium nitrate may be sprayed to
increase sugar content especially during the wet season.
Cut the shoot at the 5th node and allow two uniform vines to
form a Y. Prune the side shoots by hand up to the 10th node.
Allow side shoots and fruiting in the 11th-15th node. The main
vines may be cut at the 25th-27th node.
|Trellised. Prune all side shoots below
the 11th node. Allow side shoots on the 11th-16th node, and fruiting
in 2-4 side shoots depending on the capacity of the variety.
Cut the tip of the fruiting vine after 1-2 leaves. The main vine
may also be cut at the 25th node.
and Fruit Selection
for good fruit setting need ample pollination. Where applicable,
bee colonies may be used but manual pollination is still best.
Collect open, male flowers between 6:00-9:00 a.m. and rub the
anthers on the stigma of the female flowers.
fruits at egg-size stage. For best results, allow only one fruit
Care and Maintenance
| Non-trellised. Inspect selected fruits for
damage. Support the fruits with halved bamboo about 2-3"
in diameter. Protect the fruits from sunscald by covering with
rice straw or cut grasses.
| Trellised. Tie the fruits with synthetic
straw on the pedicel and secure on the trellis. Wrap the fruits
with newspaper or wax paper to protect them from sunscald and
most serious problem of honeydew melon is downy mildew. Use resistant/tolerant
variety. Use systemic fungicide such as Ridomil and contact fungicide
such as Mancozeb. Apply the contact type regularly or every 4-5
days. The systemic type should be used only two times during
blight may be a problem in some areas, in which case, spray copper-based
fungicides. If infection is severe, paint a slurry of the fungicide
on the affected area. Avoid splashing water on the stem during
irrigation. Viruses could minimized by sanitation.
common pests of honeydew melon thrips, mites, aphids, squash
beetle and fruitfly. Mulching and spraying with insecticidal
soap, hot pepper spray or appropriate pesticides can control
thrips and mites. To control fruitfly, use fruitfly attractant
as early as the vegetative stage. Wrap the fruits for better
at 45-55 days from flowering or 75-80 days from transplanting.
The index of fruit maturity depends on the variety. These may
include change in color from green to yellow or a yellow tinge,
slight cracking near the pedicel, flattening of the blossom end,
and change in aroma.
fruits by cutting the fruiting vine to leave a T on the fruit.
Handle the fruits with care. Do not drop nor pile too high. Use
the plastic crates for hauling and store under the shade.
the fruits according to size, quality and market standards. Wash
the fruits in 1% sodium hypochlorite and air-dry. Apply fruit
wax to shine. Wrap the fruits individually with styrofor apron
and pack in cartons or boxes. If refrigerated transport is available,
maintain temperature at 70C.
