ORGANIC ENDIVES ROOTS
Three types of production are defined according to the sowing and pulling-out periods: – sowing in the 2nd fortnight of April under non-woven tarpaulin with a very early pulling-out objective (15 August to early September). This sowing is not recommended in organic farming because false sowing is limited and weeding is made more difficult. – early May sowing for early harvesting (early September to mid-October). The roots are forced after a week in cold storage. The withering technique allows a gain of maturity without any refrigeration system. – normal sowing in May (sometimes early June) for pulling up at maturity (late October to November). The roots are forced immediately or put into cold storage.
The coming back must be at least 5 to 6 years and its place is regulated at the end of the rotation. Crops such as peas, beans, rape, carrots, tobacco and potatoes maintain endive parasites and should be avoided. The endive must be kept away from organic matter inputs. The previous one is generally a cereal whose straws are removed or finely ground and incorporated.
The soil preparation for sowing will be of the beetroot type, but with an even finer and more compacted seedbed. The density varies from 250 to 400,000 seeds/ha in order to obtain final stands of 150,000 (very early pull-out) to 300,000 (pull-out at maturity). As the endive seed is very small, sowing should be carried out at a regular depth of 0.5 to 0.7 centimetres using a precision seed drill specific to vegetables.
