Sweet Corn
Sweet corn, scientifically known as Zea mays var. saccharata, is a type of maize with a high sugar content. Unlike field corn or dent corn, which is grown primarily for livestock feed and industrial purposes, sweet corn is consumed as a fresh or processed vegetable. It is characterized by its tender, sweet kernels and is harvested at an immature stage when the sugars are at their peak.Origins and Cultivation
Sweet corn is believed to have originated in Central America thousands of years ago. It was first domesticated by indigenous peoples, who cultivated and improved its taste through selective breeding. The cultivation of sweet corn gradually spread throughout the Americas and eventually reached Europe after the discovery of the New World. Today, sweet corn is grown in various regions worldwide, including the United States, China, Brazil, and India. It requires warm temperatures and fertile soil to thrive. Farmers plant sweet corn seeds in well-prepared soil and provide adequate irrigation. The crop typically matures within 60 to 100 days, depending on the variety and environmental conditions.Popular Varieties of Sweet Corn

To store sweet corn, keep it in the refrigerator with the husks intact.
