Bottle gourd thrives best in warm and humid climates. It requires:
Temperature: Ideal range between 25°C to 35°C.
Rainfall: Moderate rainfall is suitable; waterlogging must be avoided.
Soil: Fertile, well-drained loamy soil rich in organic matter.
pH Level: Optimal soil pH is 6.0 to 7.5.
2. Land Preparation
Plow the field 2–3 times to a fine tilth.
Incorporate well-decomposed farmyard manure (FYM) at a rate of 20-25 tons per hectare.
Ensure proper leveling and create raised beds or ridges and furrows for better drainage.
3. Varieties of Bottle Gourd
Popular varieties include:
Pusa Naveen: Cylindrical fruits with smooth skin.
Arka Bahar: Tolerant to pests and diseases.
Punjab Komal: High-yielding and suitable for summer sowing.

4. Sowing Time
Summer Crop: February to March.
Rainy Season Crop: June to July.
Winter Crop (in tropical areas): October to November under protective cultivation.
5. Seed Rate and Sowing
Seed Rate: 4–5 kg per hectare.
Soak seeds in water for 24 hours to enhance germination.

Use bio-fertilizers like Azotobacter and mycorrhiza for sustainable growth.
8. Weed Management
Conduct hand weeding or hoeing at regular intervals.
Mulching with straw or plastic can reduce weed growth and conserve soil moisture.
9. Training and Pruning
Provide bamboo stakes or trellis system for proper vine support.
