14. SOIL AND CLIMATE
• Tropical, subtropical and semi arid crop
• Cannot tolerate frost or low temperature
• Seed germination - 18 to 25%
• Successfully grown in 15-32°c
• Short day, low temperature leads to femaleness.
• High temperature leads to male flower and flower drop.
• Sandy loam or loamy soil is suited for cultivation.
• Sensitive to acidic soil pH-6.5-7.5

15. SOWING
• Goa, Konkan areas of Maharashtra, Karnataka : June-July
• Rajasthan and West Bengal : January to March
• Kerala, Tamilnadu: Feb- May

16. SEED RATE AND PLANTING METHOD
• Seed rate: 2-3kg/ha
Planting method-
1. Ridge method.
• Ridge and furrow- 2.5m distance, furrow width-40-45cm, depth-15-
20cm
• Seeds are sown at a distance of 75-100cm
2. Flat bed method- shallow pits of 30cm length,30cm width and 30cm
depth at a distance of 150cm between rows and 75-100cm between
plants.
• Sowing depth-1.5-2cm

17. NUTRITIONAL REQUIREMENT
• Well decomposed FYM-20-25t/ha
• Nitrogen- 40kg/ha
• N is applied as a basal dose and at the flowering time.

18. IRRIGATIONIn
• Rainfed irrigation , no need of water supply
• In semi-arid areas irrigation interval is 5-7 days.
• Drip irrigation is successful in many cucurbits.
*In CIAH, Bikaner, use of drip and micro-sprinkler system increase fruit
yield by 25-30%

19. Mulching
• Reduces evaporation
• Delays drying of soil
• Checks weed population
• Increases microbial activity
• Mulching with locally available dry hays improved the quality of fruit
yield by 58% over control in cultivar AHS 82.

20. Maturity indices
• An abscission layer is fully developed
• Fruit is easily separated from the peduncle
• Colour changes to pale yellow- orange
• Fruit burst (phoot)

22. YIELD
• Fruit yield - 150-200q/ha
• Seed yield – 1-3q/ha.

23. POST HARVEST MANAGMENT
• Storage
• Snap melon fruits are perishable and can be stored for 2-4 days at
room temperature
• In cold store at 2-4C and 85-90% RH , the fruits can be stored for 2-3
weeks.

24. • Traditionally it is being utilised for making 'rasayna’.
• Ripe fruits are utilised for making squash, syrup, icecreams and
candies.

25. Major diseases
• Powdery mildew (Erysiphe cichoracearum)
• Downey mildew (Pseudopernospora cubensis)
• Angular leaf spot (Pseudomonas lachrymans)

26. INTEGRATED DISEASE MANAGEMENT
• Seed treatment with Captan/Thiam (0.2%) or trichoderma harzianum
@5g/kg of seeds.
• Foliar application Mancozeb (0.2%) @ 10 days interval gor downey
mildew.
• Foliar application of Dinocap(0.1%) or wettable sulphur at 15 days
interval for powdery mildew.
• Proper drainage, crop rotation are important.

27. • Rajamony et. al. (1987) reported that snapmelon is resistant to
CGMMV.
• R. S. Pan and T.A. More(1993) did the screening of melon germplasm
for multiple disease resistance for Powdery mildew, Downy mildew,
Fusarium wilt, CGMMV
• RESULT-Snap melon was highly resistant to DM, resistant to CGMMV
and moderately resistant to fusarium wilt.

28. BREEDING FOR DISEASE RESISTANCE
• Currently used varieties of muskmelon resistant to Powdery mildew
owe their origin to snapmelon accession PI 79376 from Gujarat.
• PI124111 From Kolkata is known fro resistance against powdery and
downy mildew (Thomas et. al., 1988)
• PMR45 first PM resistant variety of cantaloupe released in USA in
1934 was bred by using Indian snapmelon.
• Dhillon et al, 2007 identified many accessions of anpmelon resistant
against PM, DM, CGMMV etc.

29. PESTS
• Leaf minor (Liriomyca spp.)
• Fruit fly (Bactrocera cucurbitae)
• Red pumpkin beetle (Aulacophora foviecollis)

30. INTEGRATED PEST MANAGEMENT
• Destroy cotyledonous leaves 10 days after germination.
• Clip leaves infested with leaf minor upto 20 days after sowing.
• Mechanical collection of red pumpkin beetle.
• Spraying neem formulation with azardirachtin (2ml/l) or NSKE 4%.
• Neem soap 5gm
• For fruit fly control, crushed pumpkin 1kg + 100gm jaggery+10ml
malathion is useful.
• Erect cuelure traps @ 25traps /ha.
• Collect and destroy all infested fruits by burning or brying deep into the
soil.
