The main sowing months are June-July and December-January. In Kerala, the crop is grown throughout the year. The seed rate is 2 kg/ha. Seeds are planted at a spacing of 2.0 m x 1.5 to 2.0 m in pits of 60 cm diameter and 30 to 45 cm depth. Add well rotten farmyard manure (FYM) and basal dose of fertilizers in the pit along with some topsoil and sow 4 to 5 seeds per pit. After 2 weeks remove the unhealthy plants retaining 3 plants per pit.


Erect pandals for trailing snake gourd. Erect small wooden branches to allow the growing plants to the pandals. Side branches are removed until the growing plant reaches the pandal.


Apply farmyard manure (FYM) @ 20 25 tonnes/ha as basal dose along with a half dose of N (35 kg) and a full dose of Pโ‚‚O, (25 kg) and Kโ‚‚O (25 kg/ ha). The remaining N (35 kg) is applied in splits at fortnightly intervals.


During the initial stages of growth, irrigate the plants at an interval of 3 to 4 days. At later stages irrigate the plants on alternate days. Weeding should be done as and when required.

Diseases and pests

The important pests attacking snake gourd are flies, epilachna beetle, and red pumpkin beetle.

Fruit fly: In homestead gardens, the fruits are infested by Bactrocera cucurbitae. To give mechanical protection to the fruits they may be covered with polythene, cloth, or paper bags. The use of banana fruit traps coupled with the removal and destruction of infested fruits is very effective in controlling this pest. Traps are set at a distance of 2 m after a border row and they may be replenished after 7-9 days. The use of traps should be started just before flowering.

Epilachna beetle: Remove and destroy egg masses, grubs, and adults occurring on leaves.

Red pumpkin beetle: Adult beetles eat leaves and damage roots. Incorporate carbaryl 10% DP in pits before sowing the seeds to destroy grubs and pupae. The important diseases are downy mildew and mosaic.

Harvesting and post-harvest management

Fruits should be harvested at the tender stage. Usually, the fruits are ready for harvesting in 70-80 days after sowing. Harvesting should be done at an interval of 5-6 days. The fruits have poor shelf-life and cannot be stored for more than 3-4 days under room conditions. Fruits are packed in baskets or other containers for marketing.
