75-90 days
Leaves are stemmed and are alternate
Plant has branching tendrils.
The flowers grow singly in the leaf axils, the

5. Most well-drained soil, whether clayey or sandy
can be managed to produce a good crop
of watermelon.
Land preparation involves one or more
tillage to make the soil more suitable for seeding
and seedling establishment,
To enhance productivity
For subsequent root growth and development, and
To help control some disease problems
6. Watermelon in tunnel grown in mid
December while out of tunnel grown
in Feb-mid March
Watermelon seed germinates at soil
temperatures of 68° to 95° F (20-35ċ)
Soil pH (6 to 6.5)
Seed should be planted 1 inch deep.
Seed required usually 1 to 2 pounds
per acre(seed size, germination& plant spacing)
With plastic mulch use an in-row spacing of
1-1.5feet and between-row spacing of 6 to 8 feet
7. Watermelon required 8-10 irrigation
During flowering & fruiting irrigation
is necessary
Fertilizers :
One bag DAP & one bag Urea
1 ̸ 3 Nitrogen, half Potash & Phosphorus at
sowing time
The remaining N and K is apply between
35-70 days
Zink and Boron also apply
