Cowpea (Lobia)

Water

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

Needs about 280 mm of water here in its growing months. Rain in its months gives about 0 mm it can use in a normal year (0 mm in a dry one), and the soil holds about 100 mm from the monsoon at sowing.

Temperature

Grows best at 25–35 °C on average, and survives 15–40 °C.

Money

Yield: about 2.8 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 at last season's harvest (February–March 2026): about ₹4,086 a quintal across mandis in your state.

This week: about ₹8,965 a quintal, the middle of 22 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 October.

Typical costs are about ₹10,000 an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
