Chili pepper

Chili pepper is grown across a wide range of climates, from open-field production in warm regions to protected cultivation under greenhouses or high tunnels in cooler climates, reflecting its broad culinary and commercial importance.

Cultivars vary enormously in pod shape, size, color, and pungency, supporting both fresh-market vegetable use and dried, powdered, and processed spice products.

Family

Solanaceae (nightshade family)

Genus

Capsicum

Principal species

Capsicum annuum, with related cultivated species including C. frutescens and C. chinense

Growth habit

Tender perennial shrub commonly grown as an annual, producing fruit whose pungency is concentrated in internal placental tissue

Chili peppers originate from Central and South America, where they were domesticated over thousands of years before being spread globally following European contact, becoming deeply integrated into cuisines across Asia, Africa, and the Americas.

The crop is grown today across warm cropping regions worldwide. Production and trade figures are compiled by FAO and national agricultural statistics services.

Chili pepper requires warm growing conditions and is sensitive to frost, restricting outdoor field production to the frost-free season in temperate climates or year-round cultivation in warmer regions and protected structures.

Extreme heat during flowering can cause flower and young fruit drop, while cool temperatures slow growth and fruit development.

Chili pepper performs best on well-drained loam and sandy loam soils with good structure, supporting the crop’s moderate but sensitive root system.

Chili pepper is typically established from transplants raised in trays or seedbeds, set out once the risk of frost has passed and soil temperatures have warmed sufficiently for good root establishment.

• Cultivar selection for pungency level, pod type, and market use
• Transplanting timed to frost-free conditions and adequate soil warmth
• Staking or support in some production systems to manage fruit load
• Rotation away from other Solanaceous crops to manage shared soil-borne diseases

Nitrogen supports vegetative growth and fruit set, while calcium status is closely linked to fruit quality, since deficiency or inconsistent uptake is associated with blossom end rot, a common fruit disorder in Solanaceous vegetables.

Chili pepper benefits from consistent soil moisture, particularly during flowering and fruit development, since irregular watering is associated with fruit disorders such as blossom end rot.

Drip irrigation is widely used in both open-field and protected production to apply water precisely and maintain even soil moisture.

Bacterial leaf spot can cause lesions on leaves and fruit, reducing marketable quality, while anthracnose affects ripening fruit, particularly under warm, humid conditions. Thrips are significant pests both for direct feeding damage and as vectors of certain viruses, and aphids can also transmit viruses while feeding on foliage.

Management combines resistant or tolerant cultivars where available, sanitation, monitoring, and — where justified — locally authorized control products applied according to their labels.

Pods are hand-picked at green (immature) or fully colored (mature) stages depending on cultivar and market, with some production also harvested for drying, in which pods are left to mature and dry further before processing.

• Fresh-market vegetable use in a wide range of cuisines
• Dried and powdered spice products
• Processing into sauces, pastes, and preserved products
• Oleoresin extraction for food-industry flavoring and coloring
