Cashew farming guide for India

Cashew is drought-resistant, but targeted watering during flushing and flowering boosts nut weight.

Calendar and regions

When and where cashew is grown

Cashew is grown as a Perennial (flowering November-February) crop in India: June-August planting of grafts.

Leading states: Maharashtra, Andhra Pradesh, Odisha. Soil moisture is best kept around 30 to 50% of capacity for most of the season.

Season, stage by stage

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.

  1. 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.

  2. Flowering

    Bloom-time weather largely decides the season's crop: watch for heat, frost, rain and long humid spells.

  3. Fruit development

    Steady moisture now reduces fruit drop and improves size; a block that loses greenness faster than the rest deserves a visit.

  4. After harvest

    Recovery feeding and irrigation rebuild the tree for next season's bloom.

Disease and pest watchlist

The main risks for cashew

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.

  • AnthracnoseInfects flower panicles in wet weather.
Irrigation

Watering cashew 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.

How VarshaKrishi helps

A weekly message about your own cashew 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.

Questions

Cashew: common questions

What soil pH does cashew need?

Cashew grows best at a soil pH between 5.0 and 6.5. A soil test before the season is the reliable way to know your own field.

How much water does cashew need?

About 500 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 cashew?

Tea Mosquito Bug 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 cashew grown in India?

Cashew is grown as a Perennial (flowering November-February) crop: June-August planting of grafts.

Which states grow the most cashew?

Leading states include Maharashtra, Andhra Pradesh, Odisha. VarshaKrishi's free Watch plan covers any field in these states: you need WhatsApp and your field's location, nothing installed in the field.
