Chicory varieties for the mid season
The chicory varieties for use in the mid-season are shown below. These varieties need a growth period of 150-160 days. Wait for favourable sowing conditions for these varieties and ensure they have enough days to grow. Depending on the root properties, these chicory witloof roots can be used for forcing after six to eight weeks in cold storage and can then be forced for approx 4 months depending to the variety, maturity and quality of the root and the storage conditions of the roots. As these varieties have had more days to mature as well as a longer storage period, they can generally be forced at lower forcing temperatures (16-18 °C).
Chicory Nacre
Nacre (OK-8379) is intended for the mid-season from February to July/August and perhaps longer. The variety shows more vigor in the field than we see with Déesse. Nacre is insensitive to herbicides from the sulfonyl-urea group. The sulfonylurea resistance makes the weed control more reliable because full dosage can be used in this variety even in the rise and germination stages. Sulfonylurea herbicides have a good effect on problem weeds from the family of composites and the crucifers. The effect is very good against common weeds such as chamomile, ragwort, small ragwort, redshank, cleavers, shepherd’s purse and black nightshade.
Productive and short pit
Nacre is of the Déesse type, but the heads are a bit more robust. The closure is fine and the leaves are glossy and extend well to the top. The pith remains relatively short. Nacre is a productive variety with a fairly long forcing period well into the summer. With Nacre, a large part of the forcing season can be covered.

|---|---|---|
| Sowing period * | normal | normal - late |

The above figures should be interpreted as trends and depend on regional growing and operating conditions.
* The minimum 24-hour temperature for sowing is 12 °C. Avoid night frost.
