Land preparation:-
For bottle gourd farming, well prepared land is used. To bring the soil to fine tilth, ploughing followed by harrowing is done.
Sowing:-
Time of sowing:
The optimum time for sowing is February-March, June-July and November-December month.
Spacing:
Use row spacing of 2.0-2.5m and plant spacing of 45-60cm.
Sowing depth:
1-2cm deep seeds are sown.
Seed:-
Seed rate:
Seed rate of 2kg is sufficient for one acre land.
Seed treatment:
Seed is treated with [email protected]% @3gm/kg to protect the seeds from soil borne fungus.
Fertilizer:-
Apply FYM (Farm Yard Manure)@20-25tonnes/acre. Application of fertilizer dose of nitrogen@28kg/acre in the form of urea@60kg/acre should be done. First dose of nitrogen@14kg/acre (urea@30kg/acre) is given at the time of sowing and second dose of nitrogen@14kg/acre (urea@30kg/acre) is given at the time of first picking.
Irrigation:-
Crop requires immediate irrigation. After sowing, immediate irrigation is given. In summer season 6-7 irrigations are required and in rainy season if needed then irrigation is given. In total, 9 irrigations are required.
Weed control:-
To control the weeds, 2-3 hoeings are required at the initial stages of plant growth. Weeding operations are carried out at the time of fertilizer application. Earthing up is also an effective way which should be carried out in rainy season.
Plant protection:-
Two to three hoeing is given to control the weeds during the early stage of bottle gourd growth. The monsoon or rainy season crop is normally stalked, often trained on a bower made of bamboos and sticks.
Pest and their control:-
Fruit fly: They feed themselves on internal tissues of fruits which cause premature fruit dropping and rotting and yellowing of fruits.
Treatment: Spray with Carbaryl@10% @ 600-700gm in 150ltr water per acre.
Pumpkin beetles: The beetles destroy the roots by feeding on themselves.
Treatment: Spray with Carbaryl@10% @ 600-700gm in 150ltr water per acre.
Epilachna beetle: The grubs destroy the plant parts by feeding on them.
Treatment: Spray with Carbaryl@10% @ 600-700gm in 150ltr water per acre.
Disease and their control:-
Downy mildew: Chlorotic spots are the symptoms of this disease.
Treatment: Spray with Mancozeb@400gm in 150ltr water per acre.
Powdery mildew: Small, white color spots are seen on leaves and stems are the symptoms of this disease.
Treatment: Spraying of M-45 or Z-78@400-500gm is used to get rid of this disease.
Mosaic: The disease causes stunted growth and yield gets reduced.
Treatment: Spray of Dimethoate@200-250ml in 150ltr water is done to get rid of mosaic.
Harvesting:-
Depending upon variety and season, crop is ready for harvesting in 60-70days. Depending upon market requirement, medium and tender fruits are harvested. Mature fruits are mostly stored for seed production purpose. Cut the fruits from vines with help of sharp knife. In peak season, picking should be done in every 3-4 days.
Post harvest:-
Keep isolation distance of 800m from other varieties of sponge gourd. Remove diseased plants from the field. For seed production, the fruits are harvested when they get physiologically mature. Three field inspections are required for the production of true to type seed. After harvesting, fruits are dried and then seeds are extracted.
