About this variety

Ajmer Ajwain-93 (AA-93) is an early-maturing ajwain population developed at ICAR-NRCSS, Ajmer. It starts flowering in just 46 days after sowing and matures in about 123 days — some 30–40 days earlier than normal-duration cultivars, which typically take 150–170 days. Its plant structure is erect, which lets growers accommodate more plants per hectare than with normal-maturity types, a higher planting density that helps offset its lower per-plant yield. The erect habit also helps it resist lodging caused by dew. AA-93 is a useful option where the rabi window is too short for a long-duration variety like GA-1 or AA-1.

Sowing & cultivation

  • Sowing timeOctober–November, or slightly later where the rabi window is compressed
  • Seed rate1.5–2.5 kg/ha for drilling; a higher plant density than normal-duration types is advised to offset its lower per-plant yield

Soil & climate

Soil

Suitable soil
Well-drained loam or clay loam; avoid waterlogging-prone land

Yield & maturity

Maturity period

~123 days

Expected yield

Lower per plant than normal-duration types; raised via higher plant density

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.

Pest & disease considerations

Major diseases

  • Not specifically documented

Advantages & considerations

Why farmers may choose it

  • Matures 30–40 days earlier than normal-duration ajwain cultivars, fitting a short or delayed rabi window
  • Erect plant type resists lodging caused by dew and allows a higher planting density

Things to consider

  • Lower yield per plant than normal-duration types — needs a higher planting density to close the gap
  • No specific disease-resistance trait documented

Frequently asked questions

Why choose AA-93 over a normal-duration ajwain variety?

AA-93 matures in about 123 days, some 30–40 days earlier than normal cultivars (150–170 days) — useful where the rabi window is short or sowing is delayed. Its lower per-plant yield is offset by planting at a higher density, thanks to its erect plant type.
