Groundnut, also known as peanut (Arachis hypogaea), is a legume crop grown mainly for its edible seeds. It is a key source of oil and protein and is widely cultivated in tropical and subtropical regions. Groundnuts grow underground and are encased in a hard, woody shell. They are used in various forms, including raw, roasted, as peanut butter, and for oil extraction. Groundnuts are rich in nutrients such as protein, healthy fats, vitamins, and minerals, making them an important food crop globally.
