Cashew

Water

Too dry to grow on rain alone. It would need irrigation.

Needs about 1,160 mm of water here in its growing months. Rain gives about 680 mm it can use in a normal year, and 510 mm in a dry year.

Grows best at 15–35 °C on average, and survives 5–46 °C.

Soil

Soil for Cashew: 8 out of 10 (good).

• The pH here suits it.
• Many fields here are short of potassium, which it needs a lot.
• Most fields here are short of nitrogen.
• Most fields here are short of organic carbon.

Likes pH 4.5–6.5.

Money

Yield: about 1.3 quintals an acre here in this season (district figures).

A new planting gives its first real harvest after about 3 years. The money here is for plants already bearing.

Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.

Mandi price at last season's harvest (March–May 2026): about ₹14,855 a quintal across India's mandis.

This week: about ₹11,475 a quintal, the middle of 6 mandis across India (latest 13 Nov).

Prices are usually best in February.

Typical costs are about ₹25,000 an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
