Ajwain

Water

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

Needs about 440 mm of water here in its growing months. Rain gives about 10 mm it can use in a normal year, and 0 mm in a dry year.

Temperature

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

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

• Nov 28 °C / 11 °C
• Dec 22 °C / 7 °C (outside its best range)
• Jan 18 °C / 6 °C (outside its best range)
• Feb 23 °C / 9 °C (outside its best range)
• Mar 28 °C / 14 °C
• Apr 36 °C / 19 °C (outside its best range)

Months in orange are outside its best range.

Nights in December can bring frost while the plants are young. Sow a little later, or cover the seedlings on cold nights.

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

Soil

Soil for Ajwain: 8 out of 10 (good).

Not in the score: nitrogen and boron.

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

Likes pH 6.5–8.0.

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 (April–May 2026): about ₹11,370 a quintal across India's mandis.

Prices are usually best in November.

Typical costs are about ₹27,000 an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
