Growing Potato in West Bengal

Updated 2026-07-13 · Region guide

West Bengal sits in the Lower Gangetic Plains with humid subtropical, high rainfall and fertile alluvium. India's top rice and potato state on fertile Gangetic alluvium. Here's how potato — a Rabi (winter) crop — fits, and how to grow it well here.

Is West Bengal good for growing potato?

When to sow potato in West Bengal

Sow in Nov and harvest around Feb. The crop takes about 90–120 days. In West Bengal's humid subtropical, high rainfall, the window matters more than anything else you do: ~1750 mm rainfall and canal + wells + heavy monsoon mean a late Rabi (winter) sowing runs potato into the wrong weather at its most sensitive stage.

Where potato actually grows in West Bengal

Hooghly leads (Singur, Tarakeswar, Dhaniakhali), with Purba and Paschim Bardhaman, Bankura, Paschim Medinipur, Nadia, Jalpaiguri and Cooch Behar, on humid Gangetic alluvium.

Where it is sold: Singur in Hooghly is the reference wholesale market. Bengal's potato splits roughly 60:40 between in-state consumption and out-of-state trade, and that 40% is the catch — the state has repeatedly banned interstate potato movement to hold Kolkata prices down, and when it does, south-Bengal cold stores clog and the farmgate price collapses (₹15/kg down to ₹11–12/kg for dala grade inside a fortnight in 2025). Bengal is also one of the few markets where the buyer asks for the variety by name.

The local risk to plan for: Policy, plus fog. An interstate movement ban is a real, recurring, entirely uncontrollable hit to your farmgate price — and potato has no central MSP to fall back on. Separately, Bengal's damp, foggy December–January is the most reliable late-blight weather in India.

Best potato varieties for West Bengal

Grown in West Bengal:

• Kufri Jyoti — the Bengal standard
• Kufri Chandramukhi — sells at a premium because buyers know the name
• Kufri Pukhraj
• Kufri Himalini

Confirm the variety is notified for West Bengal — on fertile alluvium under canal + wells + heavy monsoon, a variety bred for a different zone will underperform whatever the seed packet claims. Your West Bengal KVK or agriculture officer holds the current shortlist.

Typical yield & price

Typical yield here is around 120–160 quintal/acre. Potato has no MSP, so the price is market-driven — open YieldAI for today's live West Bengal mandi price and a sell-or-hold view.

Common problems in West Bengal

The pests and diseases to scout for:

• late blight — the defining Bengal risk, in the dew and fog of December–January
• early blight
• black scurf
• potato tuber moth in store

humid subtropical conditions shape which of these bite hardest each season — scout early and act while a problem is small. YieldAI can identify a pest or disease from a photo of your crop.

Key practices

• Watch for movement-ban announcements before you plan a sale — it is the single biggest swing factor on your price
• Jyoti and Chandramukhi fetch different rates: grade them separately and declare them honestly, the trade knows the difference
• Spray protectant ahead of the fog, not after you see lesions — dose and product from the label and your KVK
• Book cold-store space early; in a big year the stores fill and the queue is real
