Are Peanuts Grown Underground? The Cultivation of Peanuts

Are Peanuts Grown Underground

Have you ever wondered where peanuts, a common snack and ingredient in many meals, come from? Contrary to popular assumption, peanuts are legumes rather than nuts.

Is peanut production underground like that of other legumes like beans and peas?

Yes, peanuts are farmed underground, to answer your question. Peanuts develop underground and grow on little bushes, in contrast to other legumes that grow on vines above ground.

Yellow blossoms are produced by the peanut plant, which wilt and eventually forms a peg that extends into the ground where the peanut pod grows. The peanut seeds are removed from the pod and prepared for eating.

Peanuts are not regarded as root vegetables like potatoes or carrots despite their underground growing. Because of the way they grow and the structure of their seeds, they are categorized as legumes.

Consumers can better appreciate the work and attention that go into manufacturing this popular snack by being aware of the distinctive growth pattern of peanuts.

The Life Cycle of a Peanut Plant


Peanuts are planted in the soil and begin their life cycle as seeds. The seed is covered with a thin seed coat, which protects the embryo inside. When the seed is planted in the soil, it absorbs water and begins to swell. The embryo inside the seed then starts to grow and push its way out of the seed coat. This process is called germination.

Vegetative Growth

After the seed has germinated, the peanut plant enters the vegetative growth stage. During this stage, the plant develops a root system and begins to grow leaves and stems. The leaves of the peanut plant are compound, meaning that they are made up of multiple leaflets. The stem of the peanut plant is called the peg and it grows downward into the soil. The peg is what eventually becomes the peanut pod.

Reproductive Stage

Once the peanut plant has reached maturity, it enters the reproductive stage. During this stage, the plant produces flowers, which are pollinated by bees. After pollination, the flower stalk elongates and bends downward until it touches the soil. The ovary at the base of the flower then begins to develop into a peanut pod. The peg continues to grow and elongate until it reaches the peanut pod underground.


As the peanut pod develops, it goes through several stages of growth. At first, the pod is small and green. As it matures, it turns yellow and then brown. When the pod is fully mature, the plant stops growing and the leaves begin to turn yellow. At this point, the peanut plant is ready to be harvested.

In summary, the life cycle of a peanut plant begins with germination, followed by vegetative growth, reproductive stage, and maturation. Each stage of growth is crucial to the development of the peanut plant and the eventual production of peanuts.

Soil Preparation

Peanuts require well-drained soil with a pH between 5.8 and 6.2. Farmers cultivate peanuts in sandy loam soil, which is ideal for the crop. Before planting, farmers prepare the soil by plowing and tilling to a depth of 8 to 10 inches. They also add organic matter, such as compost or manure, to improve soil fertility and structure.


Peanuts are planted in rows, with a spacing of 24 to 36 inches between rows and 6 to 8 inches between plants. Farmers plant peanuts by hand or using a mechanical planter. They plant the seeds at a depth of 1 to 2 inches, depending on soil moisture and temperature. After planting, farmers cover the seeds with soil and apply a pre-emergence herbicide to prevent weed growth.


Peanuts require adequate moisture during the growing season. Farmers use various irrigation methods, including sprinkler, drip, and furrow irrigation, to provide water to the plants. They monitor soil moisture regularly and adjust irrigation schedules accordingly. Over-irrigation can lead to disease and yield loss, so farmers must be careful not to overwater.


Peanuts are ready for harvest when the leaves turn yellow and the pods mature. Farmers use a combine harvester to dig up the plants and separate the peanuts from the vines. They also use a shaker to remove excess soil from the peanuts. After harvesting, farmers dry the peanuts in the sun for several days to reduce moisture content. Finally, they store the peanuts in a dry, cool place to prevent spoilage.

Overall, peanuts are grown underground, with the plant’s fruit forming below the soil surface. Cultivation practices involve soil preparation, planting, irrigation, and harvesting, with farmers using various techniques to ensure a successful crop.

Peanut Production Around the World
