Onion farming in Kenya is a lucrative agribusiness, with two main types grown: bulb onions<\/strong> and spring onions<\/strong>. Among these, bulb onions are more popular due to their long shelf life and sweet taste. However, onion prices fluctuate<\/strong> based on the season and variety. A major factor influencing prices is the importation of onions from Tanzania<\/strong>, where production costs are lower. Farmers aiming for high profits should strategically time their production between November and May<\/strong>, when local supply is low, and prices are high.<\/p>\n\n\n\n

Best Regions for Onion Farming in Kenya<\/h5>\n\n\n\n

The best-suited areas for onion cultivation<\/strong> include Kajiado, Narok, Kieni, Karatina, Oloitoktok, Kakamega, and Naivasha<\/strong>. Onions thrive in well-drained, fertile soils<\/strong> rich in humus with a pH range of 5.8 to 6.5<\/strong>.<\/p>\n\n\n\n

    Onion Seed Requirements & Nursery Preparation<\/h5>\n\n\n\n

    An acre requires 1-1.5 kg of onion seeds<\/strong>, depending on the variety and spacing. Onions can be grown through direct seeding<\/strong> or by establishing a nursery bed<\/strong> first.<\/p>\n\n\n\n

    • 1m wide<\/strong> for easy management.<\/li>\n\n\n\n
    • Length varies depending on seed quantity.<\/li>\n<\/ul>\n\n\n\n
      Sowing and Watering<\/h5>\n\n\n\n
        \n

        • Transplant early morning, late evening, or during cloudy weather<\/strong> to prevent transplant shock.<\/li>\n\n\n\n
        • Trim shoots (3 inches) and roots (0.5 inches)<\/strong> before planting to reduce moisture loss.<\/li>\n\n\n\n
        • Spacing:<\/strong> 8-10cm between seedlings<\/strong>, 15cm inter-row distance<\/strong>.<\/li>\n<\/ul>\n\n\n\n
