Onion farming involves cultivating the bulb-forming vegetable ( Allium cepa). It’s a hardy crop that is generally grown as an annual, requiring attention to climate, soil, planting methods, pest control, and proper post-harvest handling for successful yields and storage.
Optimal Conditions: Onions thrive in a mild climate without extremes of cold, heat, or excessive rainfall. They are a cool-season crop, though they can be grown in temperate, tropical, and subtropical regions.
Vegetative Growth: Lower temperatures, typically 13−24∘C (55−75∘F), along with a shorter photoperiod (day length).
