Sweet Pepper
Introduction
Sweet pepper (Capsicum annuum), commonly known as bell pepper, is a popular and versatile vegetable consumed worldwide. Unlike hot peppers, sweet peppers have a mild, sweet flavor and come in various colors, including green, red, yellow, orange, and even purple. They belong to the Solanaceae family, which includes tomatoes, potatoes, and eggplants. Sweet peppers are not only valued for their taste but also for their rich nutritional content, economic significance, and diverse culinary applications.
This article explores the history, nutritional benefits, cultivation, economic impact, and culinary uses of sweet peppers.

Historical Background
The origin of sweet peppers can be traced back to Central and South America, where indigenous people cultivated them over 7,000 years ago. Native tribes used peppers in their diet and medicinal practices long before European explorers arrived in the New World.
In the 15th century, Spanish and Portuguese explorers introduced peppers to Europe, where they quickly spread across Asia and Africa through trade. Over time, different varieties were developed, including the sweet, thick-fleshed bell pepper we know today. By the 20th century, bell peppers became a major crop in commercial agriculture, particularly in countries with warm climates.

Like other crops, sweet peppers are susceptible to pests and diseases, including:
Aphids and Whiteflies – Suck plant sap, weakening growth.
Pepper Weevils – Damage flowers and fruits.
Powdery Mildew and Bacterial Spot – Fungal and bacterial infections that affect yield.
To control pests and diseases, farmers use organic pesticides, crop rotation, and biological pest control methods.
4. Harvesting and Storage
Sweet peppers are typically harvested when they reach full size and desired color. Green peppers are unripe versions of red, yellow, and orange peppers. They are stored in cool, humid conditions to maintain freshness.
