Tapioca (Cassava)

Water

Rain falls about 8 irrigations (5 cm each) short in a normal year, so it's risky without water.

Needs about 1,010 mm of water here in its growing months. Rain gives about 610 mm it can use in a normal year, and 440 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 39 °C / 28 °C (outside its best range)
• Jul 34 °C / 27 °C (outside its best range)
• Aug 33 °C / 26 °C (outside its best range)
• Sep 33 °C / 26 °C (outside its best range)

• May 42 °C / 27 °C (outside its best range)
• Jun 39 °C / 28 °C (outside its best range)

Months in orange are outside its best range.

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

Soil

Soil for Tapioca (Cassava): 9 out of 10 (good).

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

Likes pH 5.5–8.0.

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 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.
