Ash gourd (Benincasa hispida Cogn.)
Co 1 and Co 2 are the popular varieties
A deep loamy soil with the pH range of 5 - 7.5 is suitable. A warm tropical climate is ideal for higher yield.
Planting is done during July and January.
2.5 kg of seeds required are required for a hectare.
Soak the seeds in double the quantity of water for 30 minutes and incubate for 6 days. The seeds are treated with Trichoderma viride 4 g or Pseudomonas fluroscens 10 g or Carbendazim 2 g/kg of seeds before sowing.
Preparation of field
Plough the field 3 – 4 times. Dig pits of 30 cm x 30 cm x 30 cm at a spacing 2 x 1.5 m and form basins.
Five to six seeds are sown in each pit. After germination, the seedlings are thinned to two/ pit.
Irrigate the basin before dibbling the seeds and thereafter once in a week.
Application of fertilizers
Apply Azospirillum and Phosphobacteria @ 2 kg/ha and Pseudomonas @ 2.5 kg/ha along with FYM 50 kg and neem cake @ 100 kg before last ploughing. Apply 10 kg FYM and 100 g of 6:12:12 NPK mixture/pit as basal and 10 g N/ pit at 30 days after sowing.
Hoeing and weeding can be done as and when necessary. Spray Ethrel 250 ppm (2.5 ml/10 lit of water) four times at weekly intervals commencing from 15th day after sowing.
Quality seedling production:
In hi-tech horticulture, use 12 days old healthy seedlings obtained from shade net houses for planting. Raise the seedlings in protrays having 98 cells. Use well decomposed cocopeat is used as medium. Sow one seed per cell. Water regularly twice a day. Transplant about 12 days old seedlings in the main field
Apply 60:30:30 kg of NPK/ha throughout the cropping period through split application. 75% of phosphorus, is applied through superphosphate as basal dose.

Recommended Dose: 200:100:100 kg/ha
|Crop stage||Duration in days||Fertilizer grade||Total Fertilizer (kg/ha)||Nutrient applied||% of requirement|
|10||19:19:19 + MN |
|4||Harvesting stage||45||19:19:19 + MN |
|Total duration||115 days||Subtotal||60.00||5.00||40.10|
*75% RD of Phosphorus applied as superphosphate = 469 Kg/ha.
1. 19:19:19 = 53 kg/ha
2. 13:0:45 = 199kg/ha
3. 12:61:0 = 25 kg/ha
4. Urea = 351 kg/ha
Leaf beetles and leaf caterpillars
Leaf beetles and leaf caterpillars can be controlled by spraying Malathion 50 EC 1 ml/lit or Dimethoate 30 EC 1 ml/lit or Methyl demeton 25 EC 1 ml/lit.
1. Collect the affected fruits and destroy them.
2. The fly population is low in hot day conditions and it is peak in rainy season. Hence adjust the sowing time accordingly.
3. Expose the pupae by ploughing.
4. Use polythene bags, fish meal trap with 5 g of wet fish meal and 1 g of Dichlorvos in cotton, 50 traps are required per hectare. Fish meal and Dichlorvos impregnated cotton are to be renewed once in 20 and 7 days respectively.
5.Neem oil @ 3.0 % as need based foliar spray.
6.Aphid: Spray Imidacloprid @ 0.5 ml/lit along with sufficient quantity of stickers like Teepol, triton X100, apsa etc., for better adhesion and coverage.
Aphid: Spray Imidachloprid @ 0.5 ml/lit along with sufficient quantity of stickers like Teepol, triton X100, apsa etc., for better adhesion and coverage.
Do not use DDT, copper and sulphur dust, as these are phytotoxic.
Powdery mildew can be controlled by spraying Dinocap 1 ml/lit or Carbendazim 0.5 gm/lit.
Downy mildew can be controlled by spraying Mancozeb or Chlorothalonil 2 g/lit twice at 10 days interval.
