9. Land Preparation
• Well prepared land is required for long melon cultivation.
• To bring the soil to fine tilth , 2-3 ploughings followed by
harrowing are necessary.
• Apply 200-300 quintals /ha.

10. Bed preparation (4000m²)
10
50 m
100cm 80 m
Total no of beds = 80m / 1.5m
= 53 beds
Total length of mulch required is 53 X 50 m = 2650 m
1 k g mulch will cover about 43m² area
total mulch required = 2650 m / 43 m² = 61.62 kg

11. Laying of drip line
• For 4000m²
• Total no. of beds : 53
• lateral length 53 Х 50 = 2650m
• For two laterals / bed = 2650 Х 2 = 5300
• Total no. of emitters 5300/0.4 = 13250
13250 x 4= 53000lt/hr.

12. Mulching
• For 4000m²
• Total no. of beds : 53
• Total Length required of plastic mulch: 53×50=2650m
• we know that,
• 1kg mulch (30 micron) = 43m².
• For 4000m² = 2650/43 = 61.62 kg

Underutilized and underexploited
horticultural crops Vol.-2

15. Sowing method and spacing
• Hills are made on the inner side of the ridges of the sowing
channels.(open condition)
• For better germination , the sowing channels should be
irrigated two days before sowing .

16. Nutrient management
• Besides N:P:K @ 40:60:40 kg per hectare(open condition)
should applied at the time of sowing.
• Nitrogen at the rate of 20 kg per hectare should also be top
dressed when plant starts bearing.

Fertigation Schedule – Recommended Dose: 150:75:75 Kg/ha
No fertigation schedule standardized for long melon however, dosage recommended
for cucumber are followed:

19. 75% RD of Phosphorus applied as superphosphate = 352 Kg/ha
1. 19:19:19 = 55 kg/ha
2. 13:0:45 = 144 kg/ha
3. 12:61:0 = 9 kg/ha
4. Urea = 275 kg/ha

20. Irrigation
• Irrigate the crop once in 4-5 days(open conditions)
during summer depending upon the soil and weather
condition.
• Provide Irrigation at every alternate days for 1-2
hours in protected cultivation.

21. TRAINING

22. Intercultural practices and weed control
• Two shallow hoeing should be done before spreading of vines
to control weeds.
• Apply Fluchloralin or Trifluralin (0.75-1.5kg/ha.) as pre plant
soil incorporation at two weeks before sowing.

23. Harvesting and Yield
• The fruits are picked when they are still tender-about one-third
or one-fourth their full size.
• The fruits do not keep well for more than one day, so they
should be disposed of promptly.
• For pickling, fruits are harvested when full size but still
immature.
• The yield of long melon is about 350-400quintal/ha (open
condition).

24. Plant protection practices
1. Powdery mildew
• Symptoms
• It is caused by Erysiphae cichoracearum and E fuliginea.
• The powdery mildew on the foliage and green stems is characterized by the
appearance of tiny.
• White to dirty grey spots.They become powdery as they enlarge.
A. Fungal diseases

25. Control
• Blue copper/Blitox (0.4%) or Dithane M-45 (0.2%) bas also
been recommended to spray at 8 days interval.
• About 3-4 sprays will be enough.
• The cucurbitaceous weeds should not be allowed to grow
near cultivated field of these vegetables.

26. 2. Downy mildew
• It is caused by Pseudopernospora cubensis.
• it becomes serious during latter part of the rainy season.
• On the lower sides of these spots a purplish downy growth appears in
moist weather.

27. Control
• Badly affected vines or leaves should be removed .
• Spraying of fungicides can control the disease. Dithane M- 45
(Maneb), Dithane Z-78 (Zineb) and Tricop -50 are some of the
fungicides recommended for spraying.
• Spray thrice Blue copper blitox (0.4%) at 8 days interval.

28. 4. Fusarium wilt
• The fungus is seed-born as well as a persistent soil inhabitant.
Seedling injury is high at 20 –30o C temperature.
• Germinating seeds may rot in the soil.
• When very young seedlings are invaded, they may damp-off or die
or be stunted in growth.

29. Control
• Follow crop rotation of 10 years.
• Treat the seed with Benlate or Bavistin (2.5 g/kg seed).
• Bavistin (0.1%) or JK stein (0.1%) or Dithane M-45 (0.2%) or
Blitox (0.5%) can also afford partial control.

30. B. Bacterial diseases
• Symptoms
• This is a bacterial disease caused by Xanthomonas compestris
var. cucurbitae.
• Sometimes young stems and petioles are also attacked.
• The leaf spots appear as water soaked areas.
1. Bacterial leaf spots

31. Control
• This is a seed-borne disease, to kill the bacterium in the seeds,
hot water treatment (50oC for 30 minutes) is recommended.
• Spraying copper fungicides reduces the spread of the disease
in the field.

32. C. Viral diseases
• In older plants symptoms appear first on younger leaves.
These are alternate green and yellow patches on the leaf.
• Internodes of stems are shortened, thus dwarfing the plant.
• Young fruits are rough, mottled and deformed

33. Control
• Only virus free seeds should be used for sowing.
• All the infected plants should be eradicated from the field.
• Spray insecticides such as Thiodan (0.1 %) or Metasystox
(0.1%) or Dimecron (0.05%) or Dimethoate (0.05%) at 10
days interval to control vector population.

34. Insects
• Aphids
• Turn leaves yellow and stunt shoots
• transmit viruses from plant to plant
• Control
• Monitoring
• Spray Malathion @ 2-3 ml/lit
