Sweet Pepper

Sweet pepper is grown for its hollow, fleshy fruit, which is botanically a berry but used and marketed as a vegetable. Cultivars vary in fruit shape, wall thickness, and color at maturity, from blocky bell types to elongated or tapered forms.

Production spans open-field systems in warm climates to heated, trellised greenhouse production in cooler regions, where environmental control allows extended and more predictable harvest.

Family

Solanaceae (nightshade family)

Genus and species

Capsicum annuum

Fruit type

Botanically a berry, though grown and used as a vegetable

Growth habit

Branching, semi-woody perennial shrub in frost-free climates; grown as an annual elsewhere

Capsicum annuum originated in Mesoamerica, where wild and semi-domesticated peppers were used long before European contact. Following the Columbian Exchange, pepper spread rapidly across Europe, Africa, and Asia, and sweet, non-pungent types were subsequently developed for the fresh vegetable market.

Sweet pepper is now grown across a wide range of climates in open-field and protected-culture systems. Current statistics on planted area, production, and trade by country are compiled by FAO and national agricultural agencies.

Sweet pepper is a warm-season crop sensitive to frost and to chilling injury. Fruit set can be reduced by temperature extremes at flowering, whether from excessive heat, which can cause flower and young fruit drop, or from cool conditions that affect pollen viability.

Protected-culture systems such as greenhouses are widely used in cooler climates to buffer temperature extremes and extend the production season.

Sweet pepper performs best on well-drained, moderately fertile loams with good structure. It is sensitive to waterlogging, which increases the risk of root diseases, and to compacted soils that restrict root development.

Sweet pepper is typically established from transplants raised in a nursery. Staking or trellising is common, particularly in greenhouse production, to support the plant and improve fruit quality and airflow.

• Cultivar selection matched to fruit color, shape, and production system
• Crop rotation away from other solanaceous crops to manage shared soilborne diseases
• Staking or trellising to support plants and improve fruit quality
• Consistent irrigation and mulching to maintain even soil moisture

Sweet pepper requires a balanced supply of nitrogen, phosphorus, and potassium for vegetative growth and fruit development, with adequate calcium availability also relevant to fruit quality, as in tomato. Requirements depend on soil or nutrient-solution supply and production system.

Consistent water supply throughout the growing cycle supports even fruit development, and irregular moisture is associated with certain fruit-quality disorders. Drip irrigation is widely used in both open-field and protected-culture production.

Crop water requirements are estimated from evapotranspiration and local climate data, following reference methods published by FAO and national agricultural agencies.

Bacterial leaf spot can cause significant foliar and fruit damage, and several viruses, including tobacco mosaic virus, are of concern and can be spread mechanically or by insect vectors. Whiteflies, thrips, aphids, and spider mites are among the common insect pests.

Management combines resistant cultivars, sanitation, crop rotation, field or greenhouse monitoring, and, where warranted, locally authorized control measures applied according to their labels.

Fruit may be picked green, before full ripening, or left on the plant to ripen to its mature color, depending on market preference; fully ripened, colored fruit typically commands a premium but takes longer on the plant, affecting overall yield timing.

• Fresh consumption in salads and as a raw snack vegetable
• Cooking, roasting, grilling, and stuffing in many cuisines
• Processing into roasted, canned, or frozen products
• Use as a colorful garnish and ingredient across a wide range of dishes
