Soil: Bottle gourd production is good in many soils. But yield of bottle gourd is good in loamy soil. Bottle gourd can be cultivated in sandy soil by incorporating organic matter and necessary irrigation.
Time of Sowing: August � November.
Valley Preparation: Land should be leveled after ploughing and breaking clods by laddering. The height of valley in the land should be 15-20 cm, width 2.5 cm having suitable length. Thus valleys have to be prepared. Between two adjacent two valleys, 60 cm wide irrigation and drainage canal have to be made. In household garden, to cultivate Bottle gourd, the plants are lifted on the matcha, roofs of hut or on the tree after sowing seeds in valley.
Fertilizer application in valley: In each valley, 10 kg cow dung, 200 g TSP and 50 g MP should be applied.
Pit Preparation in Valley: Generally pits having 80-100 cubic centimeters of size have to be prepared maintaining distances between pits 3- 4 meters. In each pit, 10 kg cow dung or compost, 200 g TSP, 50 g MP fertilizers should be applied. Except urea, all fertilizers have to be mixed with soil in the pit 8- 10 days before seed sowing. Urea fertilizers have to be top dressed in two equal installments-first installment at 10 days and second installment at 35 days after seed sowing. A canal has to be made surrounding the pit and the fertilizers have to be mixed with the soil of the canal.
Seed Sowing: In each valley, 4-5 seeds should be sown. Within 4-5 days, seeds will germinate.
Hedge and Matcha Preparation: When the plant becomes 15-20 cm in height, bamboo twigs with kanchi should be inserted in the soil near the plant.
Cultural Operations: When the seedlings become some extent larger, 2 seedlings per valley should be kept and the remaining seedlings should be uprooted. The soil has to be made friable with the help of nirani. Necessary amount of water should be applied in bottle gourd plant in each day.
Pest Management: This vegetable can be infested by red pumpkin beetle. This insect should picked up and be killed. Besides, the mosaic virus disease may be caused by some species of grasses.
Crop Harvesting: The appropriate time of fruit picking or harvesting is when-
- When abundant awns are present on the fruit.
- When the nail easily enters the fruit on pressure.
- When the fruit becomes suitable for harvesting after 12-15 days of pollination.
Yield: When BARI bottle gourd-1 and BARI bottle gourd -2 are cultivated, 35-45 tons per hectare (140- 180 kg/ decimal) yield is obtained.
