Cauliflower

Description

Cauliflower is an annual or biannual plant, with a main taproot from which a more superficial rooted hair grows. Its stems are thickened, with whole leaves and few petioles, but usually oblong or elliptical. Its stem develops a central growth apex with a hypertrophied and succulent mass of white, green or slightly purple prefloral andemas depending on the variety.

In Spain, the cauliflower crop occupies approximately 7,000 hectares, which produce between 160,000 and 170,000 tons. Its production is distributed mainly in the province of Cádiz, Murcia, La Rioja, Navarra and the Valencian Community.

Soil

The crop adapts to soils of medium texture, provided that nitrogen is neither too abundant nor deficient. It is moderately tolerant of acid soils with a pH between 5-5 and 6.8. Cauliflower has, like broccoli, a resistance to moderate soil salinity.

Temperature

In the case of cauliflower, it is necessary to vernalize the plant at low temperatures to promoteits flowering. In short cycle varieties, flowering can be induced with temperatures equal to or higher than 15ºC. In the long cycle, temperatures of 6 to 10ºC are needed for 10-15 weeks.

Irrigation

Cauliflower is a plant with high water needs, especially from the middle to the end of the crop cycle. In case of water deficits its flowering phase can be affected.
