Tapioca (Cassava)

Water

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

Needs about 1,020 mm of water here in its growing months. Rain gives about 470 mm it can use in a normal year, and 350 mm in a dry year.

Temperature

Grows best at 20–29 °C on average, and survives 10–35 °C.

Money

Yield: about 149 quintals an acre, the typical figure across India (no figures for your state).

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 through the year (December 2025–November 2026): about ₹3,000 a quintal across India's mandis.

This week: about ₹3,500 a quintal, the middle of 71 mandis across India (latest 13 Nov).

Prices swing a lot from year to year, so income can be well above or below this range.

Prices are usually best in September.

Typical costs are about ₹2.4 lakh an acre: about half of what a usual harvest earns (2023–2025), as in farm cost surveys. They are spent whatever the harvest.
