Kutki Stolon Harvest Model: Sustainable Picrorhiza Farming in Mandi
Why in the news
Growers in Mandi district have shown a way to harvest Kutki without killing the plant. Only the creeping side stolons are cut, which turns a herb once stripped from the wild into a perennial farm crop.
Key facts
- Botanical name: Picrorhiza kurroa; Ayurvedic names Katuki or Katukarohini; local name Kadu.
- Old practice of uprooting the whole plant caused wild populations to collapse.
- New model: cut lateral creeping stolons only; the mother rhizome regenerates.
- With stolon cuttings, harvest comes in about 2-2.5 years, in September-October as aerial parts wither.
- Cuttings multiply faster and give higher yield than seed propagation.
