In Kenya, onion farming is flourishing with the cultivation of bulb onions and spring onions in key regions like Karatina, Oloitoktok, Naivasha, Kieni, Emali, and Mai Mahiu. Bulb onions typically mature within 3 to 4 months, with the short rains between January and February offering a prime harvesting window due to limited onion supply from Tanzania. This scarcity boosts local farmers' profits. After the long rains in March, onion prices surge, presenting another opportunity for farmers to capitalize on favorable market conditions. Conversely, spring onions, prized for their versatility in salads and soups, offer health benefits such as blood sugar regulation and cholesterol reduction. Despite these advantages, bulb onions remain more popular for their extended shelf life and sweet flavor.

Ideal Conditions for Onion Farming: Onions thrive in well-drained, fertile sandy loam soils with a pH range of 5.8 to 6.8. This crop can be cultivated year-round through irrigation, making it accessible to most parts of Kenya. However, to optimize production in regions like Ukambani and the Coastal area, greenhouse cultivation coupled with drip irrigation is recommended. Greenhouses regulate temperatures in hot climates, while drip irrigation ensures consistent water supply, critical for onion growth. Besides land, essential requirements include DAP fertilizer and seedlings, with popular varieties like Red Coach F1 known for their high yield and market suitability.

Overcoming Challenges in Onion Farming: Excess Water: Combat waterlogging from heavy rainfall by planting during short rains or using raised beds for proper drainage. Disease Management: Safeguard onions from diseases like Downy Mildew and Botrytis with quality fungicides. Pest Control: Address pests such as thrips and nematodes using effective pesticides to protect onion crops. Weed Suppression: Control weeds with Commander 240EC herbicide to maximize yields until harvest.

Optimal Harvesting Practices: Harvest bulb onions when a shiny membranous cover forms around the bulbs or foliage begins to wither. Spring onions are ready at a height of 15 centimeters and 1.5 centimeters in thickness. Post-harvest, sun-dry bulbs before storage to preserve quality.
