Is ajwain (carom) profitable and what yield and price range can I expect?

Ajwain is a low to moderate yielding seed spice, with a well managed crop giving a few quintals of seed per acre. Its appeal is the price, as ajwain usually fetches a good rate per quintal compared with field crops, though spice prices are volatile and can swing a lot between years. It suits well drained land and growers who can manage a careful seed crop and clean drying. Profit can be attractive in a good price year but a single crop failure from waterlogging or disease hurts. Check current ajwain rates at spice markets like Neemuch or Unjha and ask local growers for realistic yields and costs before deciding rather than assuming peak prices.
