Onion Farming Practices in Kenya: From Nursery Preparation to Harvesting Techniques

Successful onion farming starts with proper nursery preparation. The process begins with seed treatment using appropriate fungicides to prevent seedling diseases. You’ll need to prepare raised nursery beds 1 meter wide and 15-20 cm high for good drainage.

Nursery Bed Preparation Steps:

Clear the land of weeds and debris
Mix topsoil with well-decomposed manure
Level the bed surface
Create shallow furrows 1-2 cm deep
Sow seeds thinly in rows
Cover with a thin layer of soil
Water gently using a fine sprayer

The seedlings remain in the nursery for 6 weeks before transplanting. During this period, maintain consistent moisture and protect young plants from direct sunlight using shade nets. This stage is crucial, as highlighted in our article about what makes a good nursery which outlines key qualities farmers should look for.

Transplanting Guidelines:

Space plants 10 cm apart within rows
Maintain 30 cm between rows
Plant at a depth where the base of the plant sits at soil level
Water immediately after transplanting

Proper spacing allows adequate airflow, reducing disease incidence and promoting optimal bulb development. The recommended plant population ranges from 160,000 to 180,000 plants per acre.

Harvesting Indicators:

Bulb Onions:

Harvest at 3-4 months after transplanting
Watch for yellowing or falling leaves
75% of leaves should be bent over

Spring Onions:

Ready when stems reach 15 cm height
Look for thick, firm stems
Harvest before bulb formation begins

The harvesting process requires careful handling to prevent bruising. Pull the plants gently from the soil during early morning hours when temperatures are cool.
