We are all familiar with the term “groundnut.” It’s one of the most popular snacks, and we commonly refer to it as peanut. Peanuts are used for nourishment and are one of the most popular culinary items. Did you realize that groundnut is not the botanical name for groundnut? The botanical name for groundnut is Arachis hypogaea. In this article, you will learn about the botanical name of groundnut, its family, the origin of groundnut, and its uses.
Introduction to Groundnut
Groundnuts, also known as peanuts, are legumes that grow underground. The plant produces yellow flowers above ground, while the pods that contain the edible seeds develop underground. Groundnuts are actually more closely related to beans and lentils than nuts. They grow in pods underground, which is how they got the name ‘groundnut’. Once the pods mature, the whole plant is pulled up, dried in the sun and the nuts are shelled.
Groundnuts are highly nutritious, packed with plant-based protein, healthy fats, and various vitamins and minerals like folate, niacin, thiamine, and magnesium. They contain resveratrol, an antioxidant also found in red wine that may help reduce inflammation in the body. Groundnuts are also high in niacin, magnesium, phosphorus, manganese and B vitamins. Groundnuts are extremely versatile. They can be eaten raw, roasted, boiled, or ground into peanut butter. Peanut butter is a popular spread used in sandwiches, sauces, and baked goods. Groundnuts also pair well in many savory and sweet dishes like satay, spring rolls, curries, and cookies.
The unsaturated fats found in groundnuts may help lower cholesterol levels and reduce the risk of heart disease when consumed in moderation. They contain compounds like phytosterols, antioxidants, and arginine that can benefit heart health. However, groundnuts are high in calories, so portion control is key. Today, the leading commercial producers of peanuts are China, India, Nigeria, and the United States. The peanut plant is a low-growing annual herb, usually 1 to 2 feet tall. The peanut itself grows underground, which is why it’s commonly known as a groundnut.
In summary, groundnuts are a nutritional powerhouse with many health benefits when consumed properly. Their delicious flavor and versatility make them ideal for snacking or using in recipes. No wonder groundnuts have become popular all over the world!
Other Common Names for Groundnut
Groundnut goes by many other names around the world. Here are few of the most well-known ones:
- Peanut – This is the most common name for groundnut in North America. Peanut comes from the Portuguese word ‘amendoim’ meaning ‘almond’.
- Monkey nut – Groundnut is often called monkey nut in parts of Asia, Africa and the Caribbean. This name comes from the notion that monkeys like to eat groundnuts.
- Pinda – In parts of India and South Africa, groundnut is commonly known as pinda. This name comes from Portuguese traders who brought groundnuts to Africa in the 16th century.
- Kacang tanah – In Malaysia and Indonesia, groundnut is known as kacang tanah which literally means ‘ground bean’ or ‘earth nut’ in Malay.
- Nilakadalai – In South India, especially in Tamil Nadu, groundnut is called nilakadalai. Nilakadalai comes from the Tamil words ‘nila’ meaning ‘ground’ and ‘kadalai’ meaning ‘nut’.
Other names for groundnuts also include, goober, goober pea, earthnuts, goober peas, pygmy nuts and pig nuts.
History and Origin of Groundnut
Groundnut is thought to have originated in South America, likely in regions that correspond to modern-day Bolivia, Brazil, and Paraguay.
Archaeological evidence shows groundnuts were cultivated as early as 2000 BC in South America. The plant was later spread to other regions by Portuguese and Spanish explorers in the 16th and 17th centuries. Groundnuts were introduced to Africa by the Portuguese, then spread to Asia.
Today, groundnuts are an important crop and food source for millions of small farmers in Asia, Africa, and South America. The plant is well adapted to tropical and subtropical climates, requiring warm weather and medium to low rainfall.
Groundnuts have a fascinating characteristic of ripening underground. After the yellow flowers are pollinated, the fertilized ovary begins to develop into pods. The pods or fruit stalks then bend downwards and bury themselves in the soil. The pods continue to develop underground into the familiar groundnut shells containing the edible seeds. What an ingenious strategy for protecting the developing seeds!
The botanical name and history of the groundnut provide insight into its cultural and agricultural significance worldwide. Though originating in South America, the groundnut has truly become a crop of global importance.

Cultivation of Groundnut (Arachis hypogaea)
To cultivate groundnuts, follow these steps:
Selection of site
Choose a site with well-drained, sandy loam or loamy soil and a neutral pH. Groundnuts require full sun, so select an area that gets plenty of direct light during the day.
Land preparation
Plow the land thoroughly to obtain a fine tilth. Remove any weeds. Groundnuts have a taproot, so they require deep plowing.
Sowing seed
Sowing Sow the seeds at a depth of 5 to 8 cm. Drop 2-3 seeds in each hole. Space the holes about 20 cm apart. Sow the seeds in rows 45 to 60 cm apart.
Thinning
Thin the seedlings after germination, retaining two healthy seedlings per hole. This will provide adequate aeration and sunlight to the developing plants.
Irrigation
Irrigate the crop regularly, especially during flowering and pod formation. Moist soil will help produce high yields. But do not overwater, as too much moisture can lead to fungal diseases.
Fertilizer application
Apply nitrogen, phosphorus, and potassium. Fertilizers like urea, single superphosphate, and muriate of potash are commonly used. Follow the recommended application rates based on soil tests.
Weed control
Control weeds through manual weeding and hoeing. Weeds compete with the groundnut plants for nutrients, moisture, and sunlight.
Harvesting
Harvest the crop when the leaves start yellowing and shedding. Gently uproot the plants and sun-dry the pods. Once dried, remove the pods and shell them to separate the kernels. Proper drying and storage helps avoid aflatoxin contamination.
Uses of Groundnut (Arachis hypogaea)
Groundnuts, also known as peanuts, are remarkably versatile. Here are eight main uses of this nutritious legume:
