Les temp\u00e9ratures chaudes des derniers jours ont favoris\u00e9 les lev\u00e9es. Plusieurs parcelles sem\u00e9es dans les premi\u00e8res semaines de semis ont des lev\u00e9es sup\u00e9rieures \u00e0 85% et d\u00e9veloppent leur deux premi\u00e8res vraies feuilles.<\/p>\n

Des d\u00e9g\u00e2ts de gel ont \u00e9t\u00e9 signal\u00e9s dans plusieurs parcelles. Les d\u00e9g\u00e2ts sont visibles, souvent sous le sol, en d\u00e9terrant la betterave et en observant un r\u00e9tr\u00e9cissement de l\u2019hypocotyle (tigelle). Les enseignements du pass\u00e9 nous rappellent de ne pas ressemer trop pr\u00e9cipitamment\u00a0! Pour bien \u00e9valuer la d\u00e9cision du re-semis, nous vous conseillons de compter le nombre de betteraves viables par 10 m\u00e8tres, \u00e0 diff\u00e9rents endroits du champ et dans diff\u00e9rents lignes de semis.<\/p>\n

Un re-semis n\u2019est recommand\u00e9 que si le nombre est inf\u00e9rieur \u00e0 18 plantes viables (20 pour semis 50 cm) par 10 m\u00e8tres.<\/p>\n

Les d\u00e9g\u00e2ts de gel peuvent \u00eatre plus importants dans les terres finement pr\u00e9par\u00e9es. Aujourd\u2019hui, on compte environ 100 hectares de re-semis, principalement pour cause de gel et quelques parcelles pour encro\u00fbtement.<\/p>\n
