Typical values for India. Your soil test and your local KVK's advice come first.
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.
Sowing and emergence
Shallow roots need frequent light watering; an uneven stand shows up quickly as thin greenness.
Leaf growth
Nitrogen drives leaf yield; dense, humid canopies raise the risk of downy mildew.
Cutting and regrowth
Regrowth after each cutting depends on moisture recovering quickly.
The main risks for cumin
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.

- Alternaria blightCloudy humid days at flowering are the classic trigger.
- Fusarium wiltSoil-moisture and temperature history flags predisposing conditions.
Watering cumin well
Frequent, shallow irrigation. Avoid over-watering in dense canopies, which drives fungal losses.
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 cumin 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.

Cumin: common questions
What soil pH does cumin need?
Cumin grows best at a soil pH between 7.0 and 8.0. A soil test before the season is the reliable way to know your own field.
How much water does cumin need?
About 200 mm over a season of roughly 120 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 cumin?
Blight 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 cumin grown in India?
Cumin is grown as a Rabi crop: November sowing, February-March harvest.
Which states grow the most cumin?
Leading states include Gujarat, Rajasthan. VarshaKrishi's free Watch plan covers any field in these states: you need WhatsApp and your field's location, nothing installed in the field.
