Turmeric farming guide for India
Turmeric, like ginger, is a rhizome that requires substantial water but zero stagnation.

Typical values for India. Your soil test and your local KVK's advice come first.
When and where turmeric is grown
Turmeric is grown as a Kharif (8-9 month crop) crop in India: April-June planting, January-March harvest.
Leading states: Telangana, Maharashtra, Tamil Nadu. Soil moisture is best kept around 60 to 80% of capacity for most of the season.
What to watch on your field
What a weekly satellite and weather view of your own field shows at each stage, and when to walk the field.
Planting
Rhizomes rot in saturated beds; good drainage in the first weeks is critical.
Tillering
Steady moisture drives branching; a patch that stays waterlogged after rain needs attention.
Rhizome development
This stage sets final yield weight; both drought and waterlogging cut it sharply.
Drying off before harvest
A controlled dry-down before lifting improves quality and makes harvest easier.
The main risks for turmeric
Most of these follow the weather. A risky week is a reason to inspect the crop, not to spray by default.
For any spray or dose, ask your KVK or an agronomist. VarshaKrishi's free Watch plan never names a product.

- Rhizome rotSaturated beds are the trigger.
- Leaf blotchHumidity-linked Taphrina spotting.
Watering turmeric well
Raised beds with drip or light irrigation and good drainage. Saturated soil after heavy rain is the main risk.
Crop water use follows the FAO-56 method: the weather sets a reference demand, and the crop's stage sets how much of it the crop uses. That is why the same field needs different amounts in different weeks.
A weekly message about your own turmeric field.
Watch is free for any field in India: what changed on your field this week, the weather for your village, and a clear note when the satellite cannot see. Decide opens crop by crop after an agronomist reviews each crop model.

Turmeric: common questions
What soil pH does turmeric need?
Turmeric grows best at a soil pH between 5.5 and 7.5. A soil test before the season is the reliable way to know your own field.
How much water does turmeric need?
About 1500 mm over a season of roughly 270 days, from rain and irrigation together. The real need changes with the weather, the soil and the crop's stage, which is why it helps to track your own field week by week.
What is the main disease or pest risk for turmeric?
Leaf Spot is the main risk. Most risks follow the weather, so a risky week is a reason to inspect the crop. Ask your KVK or an agronomist before any spray.
When is turmeric grown in India?
Turmeric is grown as a Kharif (8-9 month crop) crop: April-June planting, January-March harvest.
Which states grow the most turmeric?
Leading states include Telangana, Maharashtra, Tamil Nadu. VarshaKrishi's free Watch plan covers any field in these states: you need WhatsApp and your field's location, nothing installed in the field.
