Tapioca (Cassava)

Water

Rain falls about 7 irrigations (5 cm each) short in a normal year, so it's risky without water.

Needs about 880 mm of water here in its growing months. Rain gives about 570 mm it can use in a normal year, and 490 mm in a dry year.

Temperature

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

Nights in January can bring frost. When frost is forecast, water the field lightly in the evening.

Soil

No soil score here: the soil tests don't say enough about nitrogen, phosphorus or potassium.

Likes pH 5.5–8.0.

Money

Yield: about 83 quintals an acre, the typical figure in your state (its government crop records list none for your district).

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 70 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.
