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.
Before flowering
Many orchard crops are deliberately kept dry before flowering to induce bloom. A falling water signal in this window is expected, not stress.
Flowering
Bloom-time weather largely decides the season's crop: watch for heat, frost, rain and long humid spells.
Fruit development
Steady moisture now reduces fruit drop and improves size; a block that loses greenness faster than the rest deserves a visit.
After harvest
Recovery feeding and irrigation rebuild the tree for next season's bloom.
The main risks for arecanut
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.

Watering arecanut well
Basin or drip irrigation tuned to the crop's stage, including the dry period some orchards use to induce flowering. Weekly field monitoring helps tell deliberate stress from real stress.
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 arecanut 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.

Arecanut: common questions
What soil pH does arecanut need?
Arecanut grows best at a soil pH between 5.5 and 7.0. A soil test before the season is the reliable way to know your own field.
How much water does arecanut need?
About 1500 mm over a season of roughly 365 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 arecanut?
Fruit Rot 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 arecanut grown in India?
Arecanut is grown as a Perennial crop: June-July planting under partial shade.
Which states grow the most arecanut?
Leading states include Karnataka, Kerala, Assam. VarshaKrishi's free Watch plan covers any field in these states: you need WhatsApp and your field's location, nothing installed in the field.
