Corn, also known as maize, is a cereal grain belonging to the Poaceae (grass) family and is one of the most widely grown staple crops in the world. Originating in Central America, it is now cultivated globally for food, feed, and industrial purposes.

The corn plant produces large ears filled with rows of kernels, which may be yellow, white, red, purple, or multicolored, depending on the variety. The kernels are enclosed in green husks with fine silk strands at the top.

Corn is a versatile crop, consumed directly as a vegetable (sweet corn, baby corn) or processed into flour, starch, syrup, oil, and biofuel (ethanol). It also serves as a major livestock feed ingredient.

Nutritionally, corn is a good source of carbohydrates, dietary fiber, vitamins (A, B-complex, E), and minerals (magnesium, phosphorus, iron, zinc). It provides energy and essential nutrients while being naturally gluten-free.

Corn holds economic importance as both a food grain and industrial raw material, with applications in snacks, bakery products, beverages, animal feed, and bio-based products. Its adaptability to diverse climates makes it a key contributor to global food security.
