🫑Gourds — Diverse Cucurbit Vegetables of India

In a village near Varanasi, a farmer hollows out a dried bottle gourd shell and hands it to a local instrument maker who will fashion it into the resonating chamber of a sitar. Across the country in Kerala, another farmer harvests chow-chow — the only cucurbit with a single seed per fruit — from a perennial vine that has been producing for years. From the bitterest vegetable (bitter gourd) to the longest-storing one (ash gourd, up to 12 months), gourds represent an astonishing diversity of forms, flavours, and uses within the cucurbit family.

Bottle Gourd (Lauki)

Bottle gourd is one of the most versatile cucurbit crops — used as a vegetable, for making Kofta and Petha (translucent sweet), and even for tutti-frutti (candied fruit for bakeries). The dried shell is used for musical instruments (sitar tumba, tanpura resonators) and craft items.

Key Facts

• Highly sensitive to photoperiod — day length strongly influences flowering behaviour.
• High temperature + high nitrogen induces maleness (more male flowers, fewer fruits).
• Fruit pulp is a good source of fibre-free carbohydrates — suitable for diabetic patients.
• Heterosis (hybrid vigour) is expressed through the entire life cycle — hybrids are particularly productive.

Bitter Gourd (Karela)

Momordicin gives bitter gourd its characteristic bitterness but also confers significant anti-diabetic and anti-inflammatory properties. Temperature above 40 degrees C induces maleness, reducing fruit set.

Summer Squash

Snake Gourd

Pointed Gourd (Parwal)

Varieties

• Bihar Sherif, Kalyani, Shankolia, Swarna Rekha, Dandli, Damodar, Swarna Alaukik, Chhota Hilli

---

Ash Gourd (Wax Gourd / Winter Melon)

The white waxy coating acts as a natural protective barrier against moisture loss, giving ash gourd its exceptional storage capability.

---

Chow-Chow (Chayote)

Spine Gourd (Kakrol): Dioecious cucurbit propagated by tuberous roots.

Ridge Gourd (Tori)

Varieties

Sponge Gourd

Varieties

• Pusa Chikni (smooth, early, selection), Pusa Supriya, Phule Prajakta, Harita (F1 hybrid)

Common Diseases of Cucurbits

Common Pests of Cucurbits

Red Pumpkin Beetle

• Scientific Name: Raphidopalpa foveicollis
• Damage: Grubs bore into roots; adults feed on leaves, flowers, and young fruits. Most destructive in March-April when seedlings are young.
• Management: Carbofuran 3G @ 7.0 kg/ha or Malathion 50 EC @ 0.05%

Cucurbit Fruit Fly (Most Serious Pest)

• Scientific Name: Bactrocera cucurbitae
• Damage: Female punctures fruit skin, lays eggs inside; maggots feed on pulp causing internal decay and premature fruit drop
• Management: Bait spray — 50 ml Malathion 35 EC + 0.5 kg jaggery in 50 litres water per hectare (jaggery attracts adult flies)

Cucurbit Mite (Red Spider Mite)

• Scientific Name: Tetranychus cucurbitae
• Damage: Sucks sap from underside of leaves; creates webbing; causes yellowing and bronzing
• Management: Dicofol or Ethion 50 EC @ 1.5 ml/litre (acaricides, not insecticides)
