Tapioca (Cassava)

Water

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

Needs about 960 mm of water here in its growing months. Rain gives about 180 mm it can use in a normal year, and 110 mm in a dry year.

Temperature

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

Here, in its growing months (day / night):

• Jun 41 °C / 27 °C (outside its best range)
• Jul 37 °C / 28 °C (outside its best range)
• Aug 36 °C / 27 °C (outside its best range)

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

Days in June get hotter than it likes. Young plants need shade and water then.

Soil

Soil for Tapioca (Cassava): 7 out of 10 (okay).

Not in the score: nitrogen and boron.

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

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.
