Crop Profile and Uses

Atropa belladonna (Solanaceae) is known as deadly nightshade and is valued for tropane alkaloids such as atropine-type compounds.

Commercial drug parts:

• Leaves and flowering tops
• Roots

---

Climate and Soil

The crop performs best in cool temperate conditions and fertile humus-rich soils with good drainage.

Points to note:

• Heavy waterlogged clay should be avoided.
• In warmer subtropics it behaves more like an annual and yield declines.

---

Propagation and Nursery

Propagation is by seeds, often with pre-treatment to improve germination.

Nursery recommendations:

• Raised beds with fine tilth and FYM.
• Seed treatment to reduce seedling disease.
• Transplant when seedlings are robust.

Planting, Crop Care, and Harvest

• Field transplanting in cool-season windows.
• Adequate spacing for canopy development.
• Timely irrigation and weed management.
• Leaf harvest at flowering stage for higher alkaloid content.
• Roots harvested later from established crop.
