Onion Drip Irrigation Kit


Grekkon Limited’s onion drip irrigation kit is for crops with close spacing. These are; onion, garlic, lemongrass, herbs, strawberry, and green/ French beans. A farmer will choose to have either raised beds or just plain lying land to install an onion irrigation drip kit. Commercial production of onions needs irrigation, and we train onion farmers on how to irrigate onions in Kenya. The knowledge of water requirements for onion is key to ensure that onion yield per acre is high. Key to understanding too is irrigation methods for onion; the pros and cons so as to make an informed decision.

Onion varieties in Kenya do not determine the irrigation method adopted. For example, a hybrid seed onion farmer, and another practicing Red Creole OPV variety onion farming will irrigate the same way. Spring onion farming too is largely through irrigation.

Overhead irrigation through; pivot systems, rain hose kits, rain gun, and impact sprinklers work, but are water inefficient.

How to grow onions using a drip irrigation system

  1. Bed making; Your beds will be 1M wide to allow for 3 rows of drip lines, and 30cm high for good drainage. Drainage is key to prevent bulb rot for onions and garlic, and root rot for beans as a result of stagnant water.

  2. Drip irrigation tapes laying; 3 rows of drip lines will be laid per bed. Each drip line row is 20cm apart and they will be laid 20cm from the edge of the bed. Where no beds are made, each row is 30cm apart.
