Water Chestnut

Water

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

Needs about 1,310 mm of water here in its growing months. Rain gives about 220 mm it can use in a normal year, and 180 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):

• 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)
• Sep 34 °C / 24 °C
• Oct 33 °C / 18 °C
• Nov 28 °C / 11 °C (outside its best range)

Months in orange are outside its best range.

Days in June get hotter than it likes. Time sowing so it flowers before then.

Soil

Soil for Water Chestnut: 7 out of 10 (okay).

Not in the score: nitrogen and boron.

• Soil here is often more alkaline than it likes.
• Most fields here are short of phosphorus.
• Most fields here are short of organic carbon.
• Most fields here are short of manganese.

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.
