Peanut Plant Overview

Peanut Plant Overview

The peanut plant (Arachis hypogaea) is a fascinating crop that belongs to the legume family. It is widely cultivated for its nutritious seeds, which are commonly known as peanuts. Understanding the anatomy and growth of the peanut plant is essential for successful cultivation. Let’s delve into the various aspects of the peanut plant to gain valuable insights.

Plant Anatomy

The peanut plant has several distinct parts, each playing a crucial role in its growth and development. Here is a brief overview of the main components:

  1. Roots: The peanut plant has a taproot system that extends deep into the soil, providing stability and absorbing water and nutrients.

  2. Stems: The stems of the peanut plant are slender, erect or prostrate depending on the variety, and can reach a height of 1-2 feet. These stems are covered with fine hairs and bear nodes where leaves and branches emerge.

  3. Leaves: The leaves of the peanut plant are composed of leaflets arranged in pinnate fashion. Each leaf typically consists of four leaflets, although some varieties may have more. The leaves play a crucial role in photosynthesis, converting sunlight into energy for plant growth.

  4. Flowers: The peanut plant produces bright yellow flowers that are self-pollinating. The flowers form in the axils of the leaves and are borne on short stalks called peduncles. Each flower lasts for only one day but produces a unique feature called a peg.

  5. Pegs: After pollination, the lower end of the flower elongates and becomes a peg. The peg then penetrates the soil, where the fertilized ovary develops into a peanut pod. This process is known as “pegging.”

  6. Pods: The peanut pods are formed underground, developing from the fertilized ovaries. Each pod contains two to three seeds, commonly known as peanuts. These pods undergo significant growth and maturation as the plant continues to thrive.

Plant Growth

The growth of a peanut plant is characterized by several stages, each crucial for its overall development. Let’s explore these growth stages:

  1. Germination: The growth cycle begins when the peanut seeds are planted in the soil. Adequate moisture and warm temperatures trigger the germination process, where the seeds sprout and develop into seedlings.

  2. Vegetative Growth: During this stage, the peanut plant focuses on establishing a strong root system and developing healthy leaves. The seedlings grow rapidly, branching out and forming more leaves, preparing for the reproductive phase.

  3. Flowering: The peanut plant enters the flowering stage after about four to six weeks of vegetative growth. Bright yellow flowers appear, attracting pollinators such as bees and butterflies. The self-pollinated flowers then transform into pegs.

  4. Pegging: The pegs elongate and penetrate the soil, typically within 10 days of flowering. Once underground, they form a protective cover over the developing pods, providing a favorable environment for pod development.

  5. Pod Development: As the pegs continue to grow, they give rise to the peanut pods. The pods initially appear small and green but gradually increase in size and mature. This process takes approximately 70 to 90 days, depending on the variety and environmental conditions.

Understanding the anatomy and growth stages of the peanut plant is crucial for proper cultivation practices. By providing the necessary care, nutrients, and optimal growing conditions, farmers can ensure healthy plant growth and maximize peanut yields.

Peanut Growth Stages

Peanut Growth Stages

Peanuts, also known as groundnuts, undergo several distinct growth stages during their lifecycle. Understanding these stages is crucial for successful peanut cultivation. Let’s delve into each stage to gain valuable insights into the growth process of peanuts.


The journey of a peanut plant begins with germination. After planting the peanut seeds in well-prepared soil, they absorb moisture and begin to swell. As water penetrates the seed coat, it triggers biochemical processes, activating enzymes that break down stored food reserves. Soon, a small root emerges from the seed, followed by the emergence of two cotyledons, which will eventually become the first leaves of the plant.

Vegetative Growth

During the vegetative growth stage, the peanut plant focuses on developing a robust root system and lush foliage. The young plant continues to rely on the stored food reserves within the seed until its roots become fully functional. Adequate sunlight, water, and nutrients are essential during this stage to support healthy leaf growth and strong root development.


As the peanut plant matures, it transitions into the flowering stage. At this point, the plant develops yellow, pea-like flowers. Each flower possesses both male and female reproductive organs, making peanuts self-pollinating. Pollination typically occurs through self-fertilization, aided by wind or insects. Once pollinated, the flowers fade away, making way for the next critical phase of peanut growth.


After successful pollination, a remarkable phenomenon called pegging takes place. The elongated flower stalk, known as the peg, starts growing horizontally towards the soil. Upon reaching the ground, the peg develops tiny root-like structures called geocarps, which penetrate the soil. These geocarps act as anchors, ensuring stability for the developing peanut pods. It’s interesting to note that pegging can occur at various nodes along the main stem, resulting in multiple pegs and pods per plant.

Pod Development

With the peg firmly anchored in the soil, the peanut plant directs its energy towards pod production. The geocarp swells and forms a protective shell around the developing peanuts. As the pods grow, they eventually push themselves deeper into the ground, ensuring optimal conditions for maturation. The peanut pods reach maturity within the soil, safeguarded from environmental factors that could hinder their development.

Each of these growth stages is critical for the successful cultivation of peanuts. Farmers must provide adequate water, nutrients, and optimal growing conditions to ensure healthy growth and maximum yield. By understanding the unique path peanuts take during their growth journey, farmers can make informed decisions and implement effective agricultural practices.

Now that we have explored the growth stages of peanuts, let’s move on to the exciting process of peanut harvest.

When to Harvest Peanuts

Determining the ideal time for peanut harvest depends on several factors, such as variety, growing conditions, and weather patterns. On average, peanuts are ready for harvest approximately 120 to 160 days after planting. However, it’s important to keep a close eye on your crop and look for specific signs of maturity.

One indicator that peanuts are ready for harvest is when the plants’ leaves begin to turn yellow and wither. Additionally, the pegs, which are the stems that connect the developing peanuts to the plant, should have reached a mature state, usually turning brown or black. Another helpful tip is to monitor the moisture levels in the soil. If the ground is too wet, it can lead to mold and rot, whereas excessively dry conditions may cause damage during digging.

Digging Peanuts

Once the peanuts have reached the appropriate stage of maturity, it’s time to dig them out of the ground. The digging process involves carefully uprooting the entire plant while taking care not to damage the pods. There are various methods for digging peanuts, including manual digging, mechanized equipment, or even using specialized attachments to tractor implements.

One popular manual technique is hand digging, where workers use shovels or forks to loosen the soil around the plants and carefully lift them out. This method requires precision and caution to avoid unnecessary bruising or pod damage. On the other hand, mechanized harvesting involves using specialized equipment like peanut diggers or combines, which efficiently extract the plants from the soil.

Drying and Curing

After the peanuts have been successfully dug, the next critical step is to dry and cure them. Drying is essential to reduce the moisture content in the pods, preventing the growth of mold and ensuring longer shelf life. The curing process follows drying and is crucial for developing the characteristic flavor and aroma associated with peanuts.

Traditionally, peanuts are dried by spreading them in a single layer on a clean and dry surface under the sun. This method allows for natural air circulation and evaporation of moisture. It may take several days for the peanuts to fully dry, depending on environmental conditions.

Once the peanuts are sufficiently dry, they undergo the curing process. Curing involves allowing the peanuts to rest in a well-ventilated area for a few weeks. During this time, enzymes in the peanuts promote the development of desirable flavors while reducing any residual bitterness.
