Seed Rate

Seed rate of 2 kg is sufficient for one acre land.

Seed Treatment

To protect seeds from soil borne fungus, treat seeds with Carbendazim@2gm/kg of seeds. After chemical treatment, treat seeds with Trichoderma Viride@4gm/kg of seeds or Pseudomonas fluroscens@10gm/kg of seeds.

Time of sowing
In north India, it can be cultivated for two times. It is sown in February-March and also in June -July.


Sow two seeds per hill on one side of bed which is 3 m wide and use spacing of 75-90 cm.

Sowing Depth

Seeds are sown at depth of 1-2 cm.

Method of Sowing

Seeds are directly sown on bed.


It can grow on variety of soils but gives best results when grown on sandy loam soils. Ideal pH range of soil is about 6 to 6.5.

Climate – 

Temperature – 15-35°C

Sowing Temperature – 15 – 20°C 

Harvesting Temperature – 22-35°C

Rainfall – 100- 150cm


Plough the field 3 – 4 times. Dig pits of 30 cm x 30 cm x 30 cm at a spacing of 2 x 1.5 m and form basins.

Fertilizer Requirement (kg/acre)



Nutrient Requirement (kg/acre)



Overall it required Nitrogen@40kg in form of Urea@90kg/acre, Phosphorus@20kg in form of SSP@125kg/acre and Potash@20kg in form of MOP@35kg/acre. Apply half dose of Nitrogen and full dose of Phosphorus and Potash at time of bed preparation. Apply remaining dose of Nitrogen when crop is at flowering stage.

Irrigate the basins before dibbling the seeds and thereafter once a week.

Application of ethrel at 250 ppm at 2 leaf stage and 5 leaf stage enhances female flower production.
Seeds attain physiological maturity at 80 – 85 days after anthesis when fruit stalk becomes dry and ashy coat on the fruit surface is prominent. Under sized fruits should be rejected.


Varieties : 30 – 35 t/ha
Hybrids : 80-90 t/ha

Matured fruits can be stored over sand bed at ambient condition.

Nursery raising
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 as medium. Sow one seed per cell. Water regularly twice a day. Transplant about
12 days old seedlings in the main field

1) Leef beetles

If infestation is observed, to controlled take spray of Malathion 50EC@1ml/ltr or Dimethoate 30EC@2ml/lit of water.


If infestation is observed, take spray of Imidacloprid@0.5ml/ltr of water.

Apply neemcake @ 30g/plant as spot treatment 10 days prior to sowing. Soil application of P. fluorescens @ 2.5kg/ha

1)Powdery Mildew:

Patchy, white powdery growth appear on upper surface of leaves also on main stem of infected plant. It parasitizes the plant using it as a food source. In severe infestation it causes defoliation and premature fruit ripening.
If infestation is observed take spray of Dinocap@1ml/lit or Carbendazim@0.5gm/lit of water.

2) Downy mildew: 

If infestation is observed, take spray of Mancozeb or Chlorothalonil@2gm/ltr of water, two times with 10 days interval.
