Water Chestnut

Water

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

Needs about 1,150 mm of water here in its growing months. Rain gives about 310 mm it can use in a normal year, and 210 mm in a dry year.

Temperature

Grows best at 25–30 °C on average, and survives 10–35 °C.

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

• Jul 35 °C / 27 °C (outside its best range)
• Aug 34 °C / 26 °C
• Sep 33 °C / 24 °C
• Oct 32 °C / 18 °C
• Nov 28 °C / 11 °C (outside its best range)
• Dec 22 °C / 7 °C (outside its best range)

Months in orange are outside its best range.

Soil

Soil for Water Chestnut: 8 out of 10 (good).

Not in the score: nitrogen.

• The pH here suits it.
• Salt in the soil here can harm it.
• Most fields here are short of boron.

Likes pH 5.5–7.5.

Money

Yield: about 15 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.
