History Of Maize Farming In Kenya
Maize is a staple food in Kenya, and its cultivation has a long and complex history. The crop was first introduced to the country by Portuguese traders in the 16th century, but it did not become widely adopted until the arrival of the British colonists in the 19th century.
The British colonial government promoted maize production as a way to feed the growing population of European settlers. They also introduced new varieties of maize that were better suited to the Kenyan climate. As a result, maize production increased rapidly during the colonial period.
After independence in 1963, the Kenyan government continued to promote maize production. Maize became the country’s main staple food, and it was also exported to neighboring countries. However, in the 1980s, maize production began to decline due to a number of factors, including drought, pests, and diseases.
In recent years, the Kenyan government has made efforts to revive maize production. They have introduced new varieties of maize that are resistant to pests and diseases, and they have also provided farmers with access to improved inputs and technologies. As a result, maize production has increased in recent years, but it is still not enough to meet the needs of the growing population.
Here are some key events in the history of maize farming in Kenya:
- Pre-Colonial Era (Pre-19th Century): Maize, believed to have originated in Central America, was introduced to the African continent through trade and migration. Its adoption in Kenya’s pre-colonial societies was gradual, initially confined to specific regions with favorable climatic conditions. Indigenous communities embraced maize cultivation alongside other crops. Its resilience and high yield potential contributed to its increasing popularity.
- Colonial Period (Late 19th – Mid 20th Century): The colonial era witnessed significant changes in maize farming practices. European settlers recognized the economic potential of maize and introduced improved farming techniques, such as hybrid varieties, fertilizers, and mechanization. These changes led to increased maize production and the crop’s integration into local diets.
- Post-Independence (1960s – 1980s): Following Kenya’s independence in 1963, the government prioritized agricultural development as a means of achieving food security and economic growth. The Green Revolution, a global initiative aimed at increasing agricultural productivity, influenced Kenya’s maize farming through the adoption of high-yielding maize varieties, modern farming equipment, and irrigation systems. These efforts led to significant maize production gains.
- Structural Adjustments and Challenges (1990s – 2000s): In the 1990s, Kenya implemented structural adjustments in its economy, including the liberalization of agriculture. This period saw increased private sector involvement in maize farming, but it also exposed vulnerabilities in the sector. Maize production faced challenges such as soil degradation, pest and disease outbreaks, and fluctuating market prices. Additionally, issues of land tenure and access to resources affected smallholder farmers.
- Modernization and Technological Advancements (2010s – Present): The 21st century brought about renewed efforts to enhance maize farming in Kenya. The government, non-governmental organizations, and international partners focused on improving access to quality seeds, promoting sustainable agricultural practices, and addressing climate change impacts. Agribusinesses and cooperatives have played a role in facilitating farmers’ access to markets and value chains.

Climate Requirements on Maize Farming In Kenya
Maize is a warm-season crop that requires a minimum temperature of 10-15°C for germination and growth.
In Kenya, the ideal climate for maize farming is found in areas with an altitude ranging from 900 to 2,500 meters above sea level.
These areas have a mean annual rainfall of 600 to 1,200 mm, which is well distributed throughout the growing season. However, maize can also be grown in drier areas with the help of irrigation.
Soil Requirements on Maize Farming in Kenya
Maize can grow well in a wide range of soils, but it performs best in well-drained, fertile soils with a pH range of 5.5 to 7.5.
The soil should have good organic matter content, which improves soil fertility and water-holding capacity. In areas with high rainfall, soils should be well-drained to avoid waterlogging, which can lead to poor crop growth and yield.
Soil testing is recommended to determine the nutrient status of the soil and to guide fertilizer application.
Land Preparation for Maize Farming in Kenya
Land preparation is a critical step in maize farming in Kenya, and proper preparation can contribute to higher maize yields and better crop quality.
Clearing the Land
Before planting maize, the land needs to be cleared of any bushes, trees, or grass. This is done by either manual or mechanical means. Manual land preparation involves using hoes, machetes, or slashers to cut down bushes and trees, while mechanical land preparation involves using tractors or ploughs to clear the land.
Tillage
After clearing the land, the soil needs to be tilled to prepare a suitable seedbed for maize planting. Tilling involves loosening the soil and breaking up any clumps of soil to create a smooth and even surface. This can be done using a disc harrow, chisel plough, or cultivator.
Soil Fertility Enhancement
Maize requires fertile soil for optimal growth and yields. Before planting, the soil should be tested to determine its nutrient content. If the soil lacks essential nutrients, such as nitrogen, phosphorus, and potassium, fertilizers should be applied to enhance soil fertility.
Organic fertilizers, such as manure and compost, are preferred over synthetic fertilizers due to their sustainability and affordability.
Soil pH Adjustment
Maize grows best in soils with a pH range of 6.0 to 7.5. If the soil pH is too low or too high, it can affect maize growth and yields. Lime or sulfur can be added to adjust the soil pH to the optimal range for maize cultivation.
Ridge and Furrow System
In areas with high rainfall or poorly drained soils, a ridge and furrow system can be used to improve soil drainage and reduce waterlogging.
This system involves planting maize on raised ridges and leaving furrows in between. The ridges provide a suitable planting bed for maize while the furrows allow excess water to drain away.
Planting Techniques for Maize Farming in Kenya
Maize is always planted through direct seeding. The planting material for this crop should be sown early in the season, as soon as soil conditions and temperature are favourable. Delayed planting always leads to reduced yields. In Kenya there is a drop of expected yields of 1-2% every day planting is delayed.
Planting can be done either be hand or be mechanized depending on the scale of production and farmers capability. Hand planting requires 5-10 man-days/ha. Seed is dropped in the plough furrow or in holes made with a planting stick. Planting may be done on hills or in rows, on flat land or on ridges. On heavy soils ridging is advisable, to improve drainage.
Time of planting
Maize is usually planted in Kenya during the rainy season. The ideal time for planting is at the beginning of the rainy season to ensure that there is enough moisture in the soil. In some regions, farmers plant two or three times a year to take advantage of the available rainfall.
Spacing
For pure stand of maize in Kenya the Ministry of Agriculture recommends spacing between rows of 75 cm and between individual plants 30 cm for all areas with adequate rainfall, resulting in a total plant population of 44,000 plants/ha.
In the coffee zones this can be increased to 75 cm x 25 cm giving total plant population of 53,000 plants/ha. In dry or marginal areas the recommendation is to increase spacing to 90 cm between rows and 30 cm between seeds – total population 37,000 plants /ha. Approximate seed rate is 25 kg/ha. The depth of planting is commonly 3-6 cm, depending on soil conditions and temperature. Deep sowing is recommended on light, dry soils. Animal manure or phosphatic fertilizers are applied at the time of planting.
Depth of planting
Maize should be planted at a depth of 5-10cm. Planting too shallow can lead to poor germination, while planting too deep can lead to delayed emergence and poor growth.
Seed rate
The recommended seed rate for maize in Kenya is 20-25 kg per acre. However, this can vary depending on the variety, spacing, and soil fertility.
Planting methods
There are different planting methods used in maize farming in Kenya, including drilling, broadcasting, and dibbling.
Drilling involves making furrows in the soil using a tractor or hand hoe, placing the seed in the furrow, and covering it with soil.
Broadcasting involves spreading the seed on the soil surface and covering it with soil using a hoe or rake.
Dibbling involves making small holes in the soil using a stick or dibble, placing the seed in the hole, and covering it with soil.
Pre-planting treatment
Some farmers in Kenya treat their maize seeds before planting to control pests and diseases, increase germination rates, and improve plant growth.
Treatment methods include soaking the seeds in water, applying fungicides or insecticides, and using biofertilizers.
By using appropriate planting techniques, farmers in Kenya can ensure optimal maize growth and yield, leading to increased income and food security.
Cost of Maize Production In Kenya, Expected Profits and Yield Per Acre

- Market your crops effectively.
Intercropping on Maize Farming In Kenya
Intercropping is a farming practice that involves growing two or more crops in the same field at the same time. This can be done in a variety of ways, such as by planting the crops in rows next to each other, or by planting them in a checkerboard pattern.
Intercropping has a number of advantages over monoculture (growing a single crop in a field). These advantages include:
- Increased yields: Intercropping can lead to increased yields of both crops, as the different plants can complement each other. For example, maize can benefit from the nitrogen-fixing ability of legumes, such as beans or peas.
- Improved soil health: Intercropping can help to improve soil health by increasing the diversity of plant roots in the soil. This can help to improve drainage, aeration, and water retention in the soil.
- Reduced pest and disease pressure: Intercropping can help to reduce pest and disease pressure by breaking up the pest and disease cycle. For example, some pests and diseases only attack a single crop, so by intercropping with a different crop, you can reduce the risk of your crops being attacked.
- Increased biodiversity: Intercropping can help to increase biodiversity in the agricultural landscape. This is beneficial for a number of reasons, including it can help to improve pollination, and it can provide a habitat for beneficial insects and animals.
There are a few things to keep in mind when intercropping maize:
- Choose the right crops: Not all crops are compatible with each other. It is important to choose crops that will complement each other and that will not compete for resources.
- Plant the crops at the right time: The crops should be planted so that they will mature at different times. This will help to prevent one crop from shading out the other.
- Manage the competition: It is important to manage the competition between the crops. This may involve adjusting the planting densities or using herbicides.
- Harvest the crops at the right time: The crops should be harvested at the right time to maximize yields.
Intercropping is a valuable farming practice that can help to improve yields, soil health, and pest and disease resistance. If you are looking for ways to improve your maize production, intercropping is a great option to consider.
Here are some specific examples of intercropping systems that can be used with maize:
- Maize + beans: This is a classic intercropping system that has been used for centuries. Beans fix nitrogen in the soil, which benefits the maize. Maize provides shade for the beans, which helps to protect them from pests and diseases.
- Maize + cowpeas: Cowpeas are another nitrogen-fixing crop that can be intercropped with maize. They also have deep roots that help to improve drainage and aeration in the soil.
- Maize + pumpkins: Pumpkins can help to suppress weeds in a maize field. They also provide a habitat for beneficial insects, such as ladybugs and lacewings.
- Maize + sweet potatoes: Sweet potatoes are a good choice for intercropping with maize in areas with low rainfall. They have deep roots that can access water and nutrients from the subsoil.
These are just a few examples of intercropping systems that can be used with maize. There are many other possibilities, so it is important to experiment and find what works best for your specific situation.
Harvesting Maize
Maize can be harvested by hand or by special maize combine harvesters.
The stage of maturity can be determined by yellowing of the leaves, yellow dry papery husks, and hard grains with a glossy surface.
Maize is often left in the field until the moisture content of the grain has fallen to 15-20%, though this can lead to attack by grain borers in the covered cobs. In hand harvesting the cobs should be broken off with as little attached stalk as possible. They may be harvested with the husks still attached. These may be turned back and the cobs tied together and hung up to dry.
Post Harvest Management on Maize Farming
The major problems in most maize-producing areas are reducing the moisture content of the grain to below 13%, protection from insects and rodents, and proper storage after harvest. High moisture content with high temperatures can cause considerable damage such as development of aflatoxin producing fungi, making the product unsuitable for human and animal consumption.
Maize for home consumption is either sun-dried on the cob for several days by hanging up tied husks, or put in a well-ventilated store or crib.
Easy test for moisture content: take a few grains and try to crush them with your teeth – below 13% moisture level the grains are extremely hard and almost impossible to crush this way.
Shelling (the removal of grains from the cob) is usually carried out by hand, though several hand and pedal-powered mechanical shellers are now available. The average recovery is about 75%. The shelled grain is dried again for a few days and then stored in bags, tins or baskets.
The optimum moisture content for storage is 12-13%. Traditionally, the selected cobs are stored at home in the husk above the fireplace to prevent losses by insects. This is a common practice with small-scale farmers
Crop residues are removed from the field and then used as fodder, fuel, etc.
Market Size and Opportunities for Maize Farming
The maize farming business in Kenya has great potential and lots of opportunities. According to a study, the market size for maize alone in Kenya is estimated to be around Kshs.80 billion per year, which is a staggering amount. This means that with careful planning and proper implementation of the recommended practices, you could easily make a profitable return on investment from your maize farming enterprise in no time.
From the various counties in the Republic of Kenya, there is vast demand for maize such as for poultry, brewing, animal feed and human consumption including other industrial uses. The wide range of applications means that the business opportunities are many and so you need to carefully decide on where you want to specialize depending on the area of need or demand and also based on your own strengths and weaknesses. All these variables should be taken into account when deciding on which county might be best suited for your type of maize farming venture.
So, maize farming in Kenya can be a very profitable venture. If you are interested in starting a maize farm, then it is important to do your research and plan your farm carefully. The most important things to consider when farming maize are the climate and soil conditions, and the right variety of maize to grow. As with any other business, there are pros and cons to maize farming in Kenya, so you need to weigh these before making a decision.

- IPM Programs: Implementing comprehensive integrated pest management programs tailored to local conditions can ensure a holistic and sustainable approach to pest and disease management.
Fertilizer Application On Maize Farming In Kenya
Maize farming in Kenya occurs during rainy seasons –from the months of April to August.
During the planting season, farmers prepare the land carefully in order to realize increased yields, but the challenge comes in when applying fertilizer.
For a maize plant to grow healthy, it requires nutrients at different stages, which can be provided by different fertilizers –such as Di-Ammonium Phosphate (DAP), NPK, and Calcium Ammonium Nitrate (CAN).
High yields can be realized by proper timing when top-dressing. The time you apply fertilizer to your maize will affect how much you will harvest.
Here are the steps maize farmers should observe to realize high yields.
Planting
Di-Ammonium Phosphate (DAP) fertilizer or NPK fertilizer at the rate of 50 kg per acre are advised for the planting of maize.
Here, make sure that the right amount of fertilizer is applied and well mixed with the soil. Experts advice farmers planting by hand to place a teaspoonful or soda bottle cap of fertilizer into each planting hole.
Top-dressing
After planting, 2-3 weeks, when the crop is about 45cm high Calcium Ammonium Nitrate (CAN) or Urea is the best fertilizer to apply.
Apply it at the rate of 50 kg per acre if in a low rainfall area, while in areas with high rainfall, apply the fertilizer in two splits. The first split six weeks after plating and the second after 2 weeks or just before the maize flowers.
Make sure that the soil is moist before applying the fertilizer. Use a teaspoonful of fertilizer at the base of each plant in a circular way or along the row 5cm away from the plants.
Weeding
The clean the farm the healthier the maize plant. Clear all the weeds until the maize plant flowers –this avoid competition for nutrients.
Maize is the most important food crop in Kenya, summing up as the country’s stable food. When proper manuring is applied during it growth, the country becomes secure with enough food.
