Since onions have a shallow root system, frequent irrigation is the best way to achieve high yields and uniform bulbs. This makes drip irrigation a no-brainer for onion growers.
Onion is a shallow-rooted crop and therefore does not use all the soil nutrients. Even then, leaching of nutrients to the deeper zone takes place. This refers to maintaining the availability of soil and moisture within the shallow root area. Onions are known to be surviving under tough drought conditions. But, water forms a critical element required in adequate quantities for onion crop growth, yield, and quality. Particularly in drought conditions, onions might split or form double or multiple bulbs. Besides, lack of sufficient knowledge, adequate nutrition, and plant protection management are other challenges that confront onion cultivators.
Can I irrigate my onion crop daily?
Yes. Onions have small root system, so irrigation frequency is key. The amount of time between irrigation applications can be adjusted to match both the growth stage and the soil type, empowering daily irrigation.
Can drip irrigation protect my crops?
Yes! Many onion canopy diseases thrive in high humidity environments. For example, Downey Mildew and Peronospora spread more rapidly in high humidity areas. Because drip irrigation maintains relatively low humidity, it reduces the spread of disease and the need for spraying crop protection chemicals.
Can my onions be monitored and irrigated remotely?
Advanced digital tools allow you to monitor and manage your irrigation and nutrition from the palm of your hand, giving you remote access by mobile, tablet or computer.
Why should I use drip irrigation over other irrigation methods?
Because the onion’s root system is relatively small, any resources distributed below the root zone or outside the plant radius is essentially wasted. Therefore, sprinkler systems are wasting nearly 30% of the water and nutrients you are distributing. On top of irrigating the root zone only, drip systems generate no evaporation or run-off, creating even higher levels of efficiency.
