Onion Cultivation
"Don't make her cry."
Drip irrigation improves plant health; by not wetting the aerial part of the plant, a lower incidence of fungal diseases is observed. In addition, onion is a crop sensitive to water stress and moisture variations, so drip irrigation, being a localized and high frequency irrigation system, is very suitable for maintaining constant moisture in the root zone and at the required depth. Constant moisture also results in a reduction of double bulbs, which increases the commercial value of the crop.
Frequent watering limits root development, which favors bulb thickening. The onion root system is very superficial, with 92% of water extraction in the soil occurring in the first 15 cm. Therefore, low-flow drippers are very suitable for irrigation of this crop.
Its Cultivation
Production is highly temperature-dependent and the optimum environment for germination is 25°C, while for vegetative growth it ranges from 15 to 25°C. The optimum temperature before bulb formation is 15 to 20°C and for bulb development from 20 to 25°C.
It prefers deep soils, rich in organic matter, of medium consistency and not calcareous. It is not advisable to grow onions in very sandy soils.
It is affected by excessive humidity as sudden changes can cause cracking of the bulbs. Once the plants have started to grow, soil moisture should be maintained above 50% in the first 30 cm of soil. Excessive moisture at the end of the crop has a negative effect on its conservation. It is recommended that the soil has good moisture retention in the top 15-25 cm of soil.
