Reasons for Drip Irrigation in Onion Farming:
Water Efficiency: Drip irrigation is a water-saving method that optimizes wetting patterns in onion root zones, reducing the growth of weeds and enhancing overall yield.
Balanced Water Supply: Drip irrigation provides a consistent balance in water supply to onions, ensuring individual drops accumulate to meet the required levels for efficient production, especially during critical growth stages.
Soil Moistening and Maintenance: Drip irrigation helps in soil moistening and maintains soil temperature, pH, and fertility. The drop-by-drop irrigation method prevents cooling effects, erosion, and humus removal.
Low Labor Requirements: Drip irrigation requires minimal labor, as water supply and distribution are handled through pipework, eliminating the need for additional manpower or casual workers.
Protection of Onion Bulbs and Roots: Unlike other irrigation methods with high-pressure water hitting the ground, drip irrigation minimizes exposure of onion bulbs and roots, reducing the risk of erosion.
Water and Fertilizer Distribution: Drip irrigation allows for efficient water utilization, enabling large-scale watering of onion farms. It also facilitates easy and uniform distribution of fertilizers through drip lines.
Components of Onion Drip Irrigation System:
HDPE or PVC pipes
Drip emitter (15 cm Spacing)
Water tank
Ball Valves Connectors
Tank connectors
Filters
Appropriate Onion Drip Layout:
Prepare beds spaced 1 meter apart, with a footpath for plant inspection, spraying, and harvesting.
Use 3 drip lines per bed with a uniform spacing of at least 30 cm apart.
Opt for a 15 cm drip emitter spacing to match plant spacing.
When to Plant Onions on Beds: Plant onions before the onset of rains or drip irrigation installation to enhance soil warmth for shoot development.
How to Transplant Onions: Uproot onions carefully to prevent root damage. Space onion seedlings 10 cm apart for optimal yield.
Irrigating Onions: Daily irrigation during the planting stage. Increase irrigation to at least 4 times a week as bulbs start forming. Reduce irrigation three weeks before harvest when leaves start drying.
Onion Doctor Support: Onion Doctor supports smallholder farmers across Africa with quality and affordable onion and garlic seedlings, farm planning services, soil testing, drip irrigation installation and maintenance, agronomic support, onion and garlic value packs, farm management, e-extension, and on-farm training.
Reasons for Drip Irrigation in Onion Farming
Being a water saving method it only enhances wetting patterns of onion root zones. This plays an important role in reducing rapid growing weeds that lowers yield.
Drip irrigation enhances a balance in water supply to onions. Individual drops of water accumulate to a level required for efficient production. Water is available to onions every time, mostly, during critical growth levels.
Drip irrigation moistens the soil and maintains the soil temperature, PH, and fertility. With drop-by-drop irrigation, the cooling effect, erosion, and humus removal does not occur.
Labor requirements are low for drip irrigation. With water supply and distribution done by pipework, no casuals or manpower to operate the drip system.
Drip irrigation rarely exposes onion bulbs and roots unlike other methods where water hits the ground at high pressure prone to erosion.
With minimum water utilization, you can water a large farm with more onion plants with drip irrigation. Drip allows for fertilizers to be distributed easily and uniformly through drip. Fertilizers are mixed and introduced to plants through drip lines.

Appropriate Onion Drip Layout
Beds need to be prepared and spaced 1 M apart. The space in between is good for a footpath during plant inspection, spraying and harvesting.
Use 3 drip lines per bed and ensure they have a uniform spacing of at least 30 cm apart.
Drip emitter spacing should match or conform to the plant spacing. The best drip emitter to use is 15 cm drip emitter.
When to Plant onions on Beds: The onion cloves should be planted once the beds are ready and plant spacing calculated. The best time to plant onions is before the onset of the rains or before installation of drip irrigation to enhance soil warmth for shoot development.
How to Transplant Onions: While transplanting careful uprooting is necessary to prevent the roots from damage. Spacing of onion seedlings 10 cm apart is essential for higher yield.
Irrigating Onions: The rate of irrigation depends on the stage of the onion plants. During the planting or germinating stage, the onions plants require high water levels and should be irrigated daily for up to 2 times a day. When the onions have developed leaves, the bulbs start forming. This stage requires a lot of water and sunlight.Irrigation for at least 4 times a week until the bulbs are mature enough for harvest. This is usually 3 weeks before harvest, a period when leaves start drying.
