From the red onions that dominate local markets to the white and spring varieties used in gourmet dishes, there’s a niche for every grower.
Whether you’re a seasoned farmer or just starting out, understanding onion farming means knowing more than just planting seeds. Its about from choosing the right onion variety, soil preparation, planting and spacing, managing pest and diseases and timing your harvest.
Ecological Requirements for Onion Farming In Kenya.
1.Soil- Onions thrive well in well-drained sandy loam soil to ensure successful cultivations. Heavy clay is disliked and not suitable for onion farming. The soil should range and a pH of 6.0 to 7.0.
2.Sunlight- Onions need full sunlight for proper bulb formation. They grow at a temperature of 13 degrees to 30 degrees .
3.Water- Onions require a lot of water to grow properly under drip irrigation is mostly recommended as it saves water and prevents diseases.
4.Temperature- Onion plants grow best at temperature of 13 degrees to 30 degrees.
Onion Crop Management.
Onion crop management involves various practices to ensure cultivation and production. These practices include;
1.Soil preparation- Secondary cultivation is done and soil is cultivated into a fine tilth, the soil is mixed with organic manure to provide nutrients in the soil, bed making is done to be ready for transplanting.
2.Planting techniques- Direct seeding or transplanting is done after soil is prepared. For transplanting the seedling are grown in a nursery bed for about six weeks to be ready for transplanting in a spacing of 8-10 cm from onion to onion.
3.Irrigation management- Onion are sensitive to water stress especially during bulb formation. Watering should be done twice per day depending on the climate of the area. Water should be reduced as the crop approaches maturity to allow the tops to dry and prevent secondary growth.
4.Nutrient management- Onions have high nutrient demand. Apply balanced fertilizers based on soil test. Nitrogen promotes vegetative growth, phosphorus helps in root development, potassium enhance bulb quality and its resistance to diseases. Foliar feeding supplement micronutrients if deficiencies are absent.
5.Pest and Diseases control- Common pest affecting onion crops are thrips, white flies cutworms and onion maggots. Common diseases affecting onions are purple blotch, downy mildew, neck rot, fusarium basal rot, pink rot and blight. Pest and diseases can be managed by practicing Integrated Pest Management (IPM), chemical control, cultural practices, use of resistant varieties and biological control.
6.Harvest and post harvest handling- Improve harvesting and storage techniques
Improving harvesting and storage techniques by;
- Post harvesting of onions should be sorted to remove damaged, diseased or undersized bulb to meet market quality and standards.
- Harvest timing should be crucial, harvest onion when 70-80% of the tops have fallen over and turned yellow or brown.
- Proper curing of onions to remove excess moisture its done in the field during dry weather.
- Store onions in a cool, dry and well ventilated area to prevent sprouting and rotting
