Onion (Allium cepa) is a popular vegetable grown for its pungent bulbs and flavorful leaves which are favorite seasonings ideal for spicing meat, salads, and vegetable dishes. Onion grows well in friable and well-drained loamy soil with good water holding capacity. Temperature ranges from 13 to 24°C with an optimum pH of 6-6.8. Onion can be direct-seeded or transplanted depending on the planting season. It is ready for harvest when half of the tops have fallen.
