Nutrition du ma\u00efs<\/h2>\n

Les oligo-\u00e9l\u00e9ments<\/strong>
\nLes besoins du ma\u00efs sont \u00e9lev\u00e9s en zinc et mangan\u00e8se. Les sols sablonneux ne sont pas pourvus en ces \u00e9l\u00e9ments. Des apports r\u00e9guliers sont indispensables pour un bon d\u00e9veloppement de la culture. Toute carence peut cr\u00e9er des d\u00e9sordres physiologiques importants.<\/p>\n

Zinc<\/strong>
\nLa carence en zinc appara\u00eet au stade 5 \u00e0 6 feuilles. Il est recommand\u00e9 d\u2019apporter le zinc avant ce stade.<\/p>\n

Afin de pr\u00e9venir et corriger les carences en zinc, Profert recommande d\u2019apporter 3 kg\/ha de Tradecorp\u00ae<\/sup> Zn<\/strong> d\u00e8s la lev\u00e9e. Il est fortement recommand\u00e9 de faire un deuxi\u00e8me apport au stade 5 \u00e0 6 feuilles.<\/p>\n

Mangan\u00e8se :<\/strong>
\nLa carence en mangan\u00e8se peut appara\u00eetre \u00e0 tous les stades. Elle est observ\u00e9e g\u00e9n\u00e9ralement \u00e0 partir du stade 50% de feuilles visibles. Il est recommand\u00e9 d\u2019apporter le Mn avant le stade 50% de feuilles visibles. Profert recommande d\u2019apporter 5 kg\/ha de Tradecorp\u00ae<\/sup> Mn<\/strong> \u00e0 partir du stade 6 \u00e0 8 feuilles.<\/p>\n

Les stress abiotiques\u00a0:<\/strong>
\nTout le long de son cycle, le ma\u00efs est sujet \u00e0 des stress abiotiques, plus particuli\u00e8rement le stress hydrique d\u00fb aux temp\u00e9ratures \u00e9lev\u00e9es, entrainant la perturbation des fonctions de base du ma\u00efs (photosynth\u00e8se et \u00e9vapotranspiration). Pour faire face au stress, la culture se met en repos v\u00e9g\u00e9tatif, elle ferme les stomates pour ne pas perdre plus d\u2019eau. Mais dans ce cas, elle ne peut plus pr\u00e9lever l\u2019azote du sol. L\u2019\u00e9l\u00e9ment indispensable pour la synth\u00e8se des acides amin\u00e9s qui r\u00e9gulent tous ces m\u00e9tabolismes. L\u2019apport d\u2019un bon acide amin\u00e9 permet de red\u00e9marrer imm\u00e9diatement l\u2019activit\u00e9 v\u00e9g\u00e9tative.<\/p>\n

Les produits de Profert sont issus de la recherche de ses \u00e9quipes de d\u00e9veloppement. Ces produits apportent, imm\u00e9diatement, les acides amin\u00e9s libres que la plante peut utiliser. Ce n\u2019est pas toujours le cas des autres produits disponibles sur le march\u00e9.<\/p>\n

Profert recommande d\u2019utiliser des biostimulants, tout le long du cycle de la culture, pour pr\u00e9venir et g\u00e9rer les effets n\u00e9gatifs g\u00e9n\u00e9r\u00e9s par ces stress. Profert dispose d\u2019une large gamme de biostimulants.<\/p>\n

Ci-dessous le sch\u00e9ma du positionnement des diff\u00e9rents biostimulants au cours du cycle de d\u00e9veloppement.<\/p>\n
