Ajwain

Water

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

Needs about 460 mm of water here in its growing months. Rain in its months gives about 10 mm it can use in a normal year (0 mm in a dry one), and the soil holds about 110 mm from the monsoon at sowing.

Temperature

Grows best at 16–24 °C on average, and survives 10–30 °C.

Money

Yield: about 4.3 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 (March–April 2026): about ₹11,104 a quintal across India's mandis.

Prices are usually best in November.

Typical costs are about ₹26,000 an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
