Seed Production

In February the stecklings of male-sterile, monogerm seed parent are planted in strips alternating with the multigerm pollinators in a 6:2 or 8:2 ratio with a density of around 40,000 plants/ha.

Around mid-April they begin to bolt and by the end of May the flowering starts, lasting around four weeks. In the subsequent four to six weeks as the seeds mature, the physiological foundations are laid to produce seeds of high quality.

Irrigation is the key to quality, especially during flowering time and maturation. As a consequence of many years of trials on irrigation in seed production, more and more seed-producing farmers have invested in drip irrigation. This system allows irrigation with small quantities of water as well as irrigation during hot days or in case of strong winds, thus providing for high germination rates and vigour in the seed.
