Effective methods for high maize yield production in Kenya

  1. Soil Preparation: Maize requires well-drained soils with a pH range of 5.5 to 7.5. Before planting maize, it is essential to prepare the soil correctly. The first step is to clear the land of any weeds, debris or other plant residues. The next step is to plow the land, which helps to break up soil clods and create a fine seedbed. Once the land is plowed, farmers should harrow to create a smooth surface and to break up any remaining clods. Finally, it’s recommended to apply organic fertilizers such as animal manure or compost to improve soil fertility.
  2. Seed Selection: Maize seeds are available in various types, including hybrid and open-pollinated varieties. Hybrid seeds are a cross between two different varieties and offer high yields, better pest resistance, and improved disease tolerance. On the other hand, open-pollinated seeds are more affordable and suitable for small-scale farmers. Farmers should select seeds that are disease-resistant, high-yielding, and adapted to the local climate.
  3. Planting Density: Planting density refers to the number of maize plants per unit area. Farmers should aim to plant between 50,000 to 60,000 plants per acre for high yield production. This density allows for optimal use of available resources such as sunlight, water, and nutrients. Farmers can use a planting distance of 75cm x 25cm, which results in a plant population of approximately 53,333 plants per acre.
  4. Fertilizer Application: Maize requires specific nutrients for optimal growth and high yields. These nutrients include nitrogen, phosphorus, and potassium. Nitrogen is essential for leafy growth, while phosphorus promotes root development, and potassium helps in the formation of grains. Farmers should apply fertilizers based on soil test results to avoid over or under application, which can affect maize yield. It’s recommended to apply fertilizer in three stages: at planting, when the maize is knee-high, and during the tasseling stage.
  5. Irrigation: Maize requires adequate water supply for optimal growth and high yields. Irrigation is crucial, especially in areas with erratic rainfall patterns. Farmers can use different irrigation methods such as drip, sprinkler, or furrow irrigation, depending on the availability of resources. It’s recommended to irrigate maize when the soil moisture content drops below 50% of the field capacity.
  6. Pest and Disease Control: Maize is susceptible to various pests and diseases that can affect yield and quality. Common pests include stem borers, armyworms, and thrips, while diseases such as maize lethal necrosis (MLN), maize streak virus (MSV), and gray leaf spot (GLS) can cause significant yield losses. Farmers should implement integrated pest and disease management practices, including cultural practices such as crop rotation, intercropping, and the use of resistant varieties. Farmers can also use appropriate pesticides to control pests and diseases.
  7. Harvesting: Maize is ready for harvest when the cobs have reached physiological maturity, which is indicated by the drying and yellowing of the leaves. Farmers can use different methods for harvesting maize, such as handpicking or using a mechanical harvester. It’s recommended to harvest maize early in the morning or late in the afternoon to avoid high temperatures, which can reduce the quality of the maize. Farmers should also ensure that the maize is properly dried before storage to prevent mold growth.
  8. Post-harvest Management: Post-harvest management is crucial in ensuring that maize retains its quality and value. Farmers should clean the maize thoroughly, removing any debris or broken grains. They should also dry the maize to a moisture content of 12-14% to prevent mold growth. Proper storage is also essential, with the use of airtight containers, to prevent pests and moisture from damaging the maize. Farmers can also use chemical preservatives to extend the shelf life of the maize.
