Farmers can also apply fertilizers and pesticides as needed, but it is important to follow the recommended dosage and safety precautions to avoid damaging the crop and the environment.

Climate and Soil Requirements

Groundnuts, also known as peanuts, are a warm-season crop that requires a frost-free growing season of at least 120 days. In Kenya, groundnuts are typically grown in the hot and humid coastal regions, as well as in the semi-arid areas of eastern and northern Kenya.

The ideal temperature range for growing groundnuts is between 25°C and 30°C. The crop requires well-drained sandy loam soils, with a pH range of 5.5 to 6.5. The soil should be deep, as groundnuts have a taproot system that can penetrate up to 1.5 meters in depth.

Groundnuts are sensitive to waterlogging and can easily rot in poorly drained soils. Therefore, it is recommended to grow groundnuts in raised beds or ridges, especially in areas with heavy rainfall. The crop also requires good soil fertility, with adequate levels of nitrogen, phosphorus, and potassium.

It is important to note that groundnuts are susceptible to drought stress, especially during the flowering and pod development stages. Therefore, it is crucial to ensure that the crop has access to adequate moisture throughout the growing season. Irrigation is recommended in areas with erratic rainfall patterns.

Choosing the Right Seed Variety

Groundnuts are an important crop in Kenya, and choosing the right seed variety is critical to ensure a successful harvest. When selecting a seed variety, there are several factors to consider:

  • Yield: Choose a seed variety that has a high yield potential. This will help to maximize your profits and ensure that you get the most out of your investment.
  • Disease Resistance: Look for seed varieties that are resistant to common diseases such as leaf spot and rust. This will help to ensure that your crop stays healthy and productive throughout the growing season.
  • Adaptability: Consider the climate and growing conditions in your area when selecting a seed variety. Choose a variety that is well-suited to your local conditions to ensure the best possible yield.

There are several popular seed varieties that are well-suited to groundnut cultivation in Kenya:

Variety Yield Potential Disease Resistance Adaptability
Kakamega 1 2,500 kg/ha Resistant to leaf spot and rust Well-suited to western Kenya
Red Valencia 2,000 kg/ha Resistant to leaf spot and rust Well-suited to central and eastern Kenya
Virginia Bunch 2,500 kg/ha Resistant to leaf spot and rust Well-suited to most areas of Kenya

It’s important to note that seed variety alone is not enough to ensure a successful harvest. Proper soil preparation, planting, and management are also critical to achieving high yields. Consult with a local agricultural extension agent or experienced groundnut farmer for more information on best practices for groundnut cultivation in your area.

Preparing the Land

Groundnuts are a popular crop in Kenya, and they can be grown in a variety of soils. However, it is important to prepare the land properly to ensure a good yield. Here are some steps to follow:

  • Clean the land: Remove any weeds, rocks, or debris from the land. This will help prevent competition for nutrients and water.
  • Plough the land: Use a plough to turn over the soil to a depth of at least 15cm. This will help loosen the soil and improve drainage.
  • Level the land: Use a rake or hoe to level the land. This will make it easier to plant the groundnuts and ensure they grow evenly.
  • Add organic matter: If the soil is poor, you may need to add organic matter such as compost or manure. This will help improve the soil structure and fertility.
  • Apply fertilizer: Apply fertilizer according to soil test results or general recommendations. Groundnuts require a balanced fertilizer, with equal amounts of nitrogen, phosphorus, and potassium.

By following these steps, you can prepare the land for planting groundnuts and ensure a successful harvest.


Planting and Spacing

Groundnuts, also known as peanuts, are a popular crop in Kenya due to their high nutritional value and economic benefits. Proper planting and spacing are crucial for a successful groundnut crop. Here are some tips:


Groundnuts are typically planted in well-drained soil that is rich in organic matter. They require full sun and warm temperatures, with a minimum temperature of 18°C. The best time to plant groundnuts is at the beginning of the rainy season when the soil is moist.

Before planting, the soil should be tilled to a depth of at least 15 cm and weeds should be removed. Groundnuts are usually planted in rows, with a spacing of 30-40 cm between the rows. The seeds should be planted at a depth of 5-8 cm and spaced 10-15 cm apart within the row.


The spacing of groundnuts is important for optimal growth and yield. Proper spacing allows for good air circulation, which helps to prevent diseases. It also ensures that the plants have enough space to develop a healthy root system and produce a good crop.

The recommended spacing for groundnuts is 30-40 cm between rows and 10-15 cm between plants within the row. However, the spacing may vary depending on the variety of groundnut being grown and the soil type. It is important to consult with an agricultural expert to determine the best spacing for your specific situation.

Overall, proper planting and spacing are essential for a successful groundnut crop in Kenya. By following these tips, farmers can increase their chances of a good yield and a profitable harvest.

Irrigation and Fertilization

Groundnuts require adequate water and nutrients to grow well. Here are some tips on how to irrigate and fertilize your groundnut crop:


Groundnuts require consistent moisture throughout their growing season. Irrigation should be done at regular intervals to ensure the soil does not dry out. The amount of water required will depend on the soil type, climate, and stage of growth. In general, groundnuts require 1-2 inches of water per week.

It is important to avoid overwatering, as this can lead to waterlogging and root rot. A well-draining soil is essential for growing groundnuts. If your soil does not drain well, consider adding organic matter or sand to improve drainage.

Drip irrigation is a good option for groundnut farmers, as it delivers water directly to the roots and reduces water loss through evaporation. It also helps to prevent foliar diseases caused by wet leaves.


Groundnuts require a balanced supply of nutrients to grow well. The main nutrients required are nitrogen, phosphorus, and potassium. Nitrogen is essential for vegetative growth, while phosphorus and potassium are important for root development and fruiting.

Before planting, it is recommended to apply a basal fertilizer that contains nitrogen, phosphorus, and potassium. The fertilizer should be applied at a rate of 50-100 kg per acre, depending on the soil fertility level.

During the growing season, it is important to monitor the crop for nutrient deficiencies and adjust the fertilization program accordingly. Foliar fertilization can be used to supplement soil fertilization and provide the crop with additional nutrients.

It is important to avoid over-fertilization, as this can lead to nutrient imbalances and environmental pollution. Always follow the recommended fertilizer rates and application methods.

Weed and Pest Control

One of the biggest challenges in growing groundnuts is controlling weeds and pests. Weeds can compete with the groundnuts for nutrients and water, while pests can cause significant damage to the crop. Here are some tips for effective weed and pest control:

Weed Control

  • Use pre-emergent herbicides to prevent weed growth before planting.
  • Cultivate the soil regularly to remove weeds.
  • Mulch the ground with organic materials such as straw or leaves to suppress weed growth and retain soil moisture.
  • Hand-weed the crop regularly to remove any weeds that do sprout.

Pest Control

  • Use insecticidal sprays to control pests such as aphids, thrips, and mites.
  • Introduce natural predators such as ladybugs and lacewings to control pest populations.
  • Rotate crops to reduce pest populations and prevent the buildup of soil-borne diseases.
  • Practice good sanitation by removing crop debris and weeds that can harbor pests.

By following these tips, you can effectively control weeds and pests in your groundnut crop and ensure a healthy harvest.

Harvesting and Storage

Groundnuts are ready for harvesting when the leaves turn yellow and start to dry out. The pods should be hard and rattle when shaken. It is important to harvest groundnuts at the right time to avoid spoilage and insect damage. Once harvested, the pods should be left in the field for a few days to dry out before being threshed.

Threshing can be done by hand or using a machine. To thresh by hand, the pods should be beaten with a stick or a wooden mallet to remove the nuts. A machine can be used to thresh large quantities of groundnuts quickly and efficiently.

After threshing, the groundnuts should be cleaned to remove any debris and sorted to remove any damaged or diseased nuts. The nuts can then be stored in a cool, dry place in airtight containers. Groundnuts can be stored for up to six months if they are properly dried and stored.

It is important to check the nuts regularly for signs of spoilage or insect damage. If any nuts show signs of spoilage, they should be removed and discarded to prevent the spread of disease. Proper storage is essential for maintaining the quality of the nuts and preventing spoilage.
