Maize Farming in Kenya: A Complete Guide

Maize farming, also known as corn farming, is one of the most widely grown crops around the world. It’s an essential staple in many diets and has a multitude of uses, from food to animal feed and industrial applications. If you’re considering venturing into maize farming, this step-by-step guide will give you the fundamental knowledge to get started and achieve a successful harvest.

Step 1: Preparing the Land

Timing is crucial when it comes to preparing the land for maize cultivation. Start by selecting a well-drained field with fertile soil. The best time for land preparation is during the dry season, allowing you to plow and harrow the land effectively. Remove any weeds, rocks, or debris and level the field to ensure uniform water distribution.

Land preparation during the dry season ensures all the weeds dry up after plowing and harrowing. The high temperatures ensures some if not all of the weeds are destroyed and cannot germinate.

Step 2: Seed Selection and Planting

Choose high-quality maize seeds from a reputable supplier.  Where possible buy directly from the manufacturers or accredited dealers. The selection should consider factors such as yield potential, disease resistance, and adaptability to your region’s climate.


Before planting, treat the seeds with a recommended fungicide to protect against diseases. Create furrows or ridges using a plow or hoe and plant the seeds at a depth of about 2-3 inches, leaving a spacing of around 10-12 inches between plants.

Step 3: Fertilization

Maize requires essential nutrients for healthy growth and optimal yield. Conduct a soil test to determine its nutrient composition and apply fertilizers accordingly. Nitrogen, phosphorus, and potassium are the primary macronutrients maize needs.

Apply a balanced fertilizer, such as a 10-10-10 formulation, during planting or as a top dressing later in the growing season. Follow the recommended application rates to avoid nutrient deficiencies or excesses.

Step 4: Irrigation and Weed Control

Maize thrives in moist soil conditions, so proper irrigation is vital. Irrigate regularly, especially during dry spells, to ensure the plants receive adequate water.

Excess water

Avoid waterlogging, as it can harm the roots. Additionally, implement effective weed control measures such as manual weeding, mulching, or herbicide application. Weeds compete with maize plants for nutrients and can significantly reduce yields if uncontrolled.

Step 5: Pest and Disease Management

Protecting your maize crop from pests and diseases is crucial for a successful harvest. Monitor your field regularly for signs of pests such as cutworms, armyworms, and stalk borers.

This requires hands-on skills, either to supervise your employees or by doing it yourself, don’t be a telephone farmer living in the city and making calls to see how your maize farm is doing.

Implement integrated pest management practices, including the use of biopesticides and cultural methods like crop rotation. Similarly, be vigilant against diseases like maize rust, leaf blight, and smut. Consult local agricultural extension services for guidance on effective control measures.

Step 6: Harvesting

Harvesting time depends on the maize variety and prevailing weather conditions. Monitor the crop closely for signs of maturity, such as dried husks and kernels that have hardened. Perform a simple moisture test by hand to ensure the moisture content is around 14-15%. Harvest the cobs using a sharp knife or machete, and handle them carefully to avoid damage.

Step 7: Drying and Storage

it’s not finished until it is finished. Properly drying and storing maize is essential to prevent post-harvest losses. Spread the harvested cobs on a clean, dry surface for air drying. Once the moisture content is reduced to around 12-13%, transfer the maize to well-ventilated storage facilities such as grain bins or silos. Protect the stored maize from pests, rodents, and moisture, and regularly inspect for any signs of spoilage.

Maize farming conclusion

Maize farming can be a rewarding venture if you follow these step-by-step guidelines. Remember to prepare the land adequately, select quality seeds, provide proper nutrition and irrigation, and control weeds.
