La compréhension de ce qui se passe dans un plant de maïs est importante pour votre rendement final. De manière à suivre le progrès de la croissance de votre maïs, nous utilisons une légende uniformisée des moments clé de son développement. Le stade végétatif du maïs est identifié par la lettre V. Au fur et à mesure que chaque feuille se déroule du cornet, une collerette se forme. Ces collerettes sont identifiées successivement par les numéros 1, 2, 3, 4, 5, etc… Le maïs au stade V6 peut posséder entre 7 et 9 feuilles, selon votre façon de compter et selon la vitesse de développement du maïs – d’où la référence au nombre de collerettes. Il y a 3 segments principaux dans les stades V et ils sont cruciaux afin de déterminer quelle sera votre rendement en maïs :<\/p>\n\n

V5 – le nombre de pousses potentielles d’épi est fixé<\/p>\n\n

V6-V8 – le nombre de rangs potentiels de grains de maïs est fixé<\/p>\n\n

V8-V15 (approximatif) – le nombre de grains potentiels par rang est fixé<\/p>\n\n

Le stress généré, soit par l’environnement ou le producteur lui-même, peut entrainer des résultats catastrophiques. Par exemple, au stade V7 (environ 8 à 9 feuilles), le stress d’une sécheresse ou l’application d’un herbicide que la culture ne peut pas tolérer peut entrainer une réduction des rangs de grains. Si le maïs passe en phase V8 avant que le stress ne soit éliminé, il peut s’en suivre également une réduction du nombre de grains par rang. La réduction de 2 rangs de grains et de 10 grains sur la longueur de l’épi signifie une perte de 6,7 boisseaux par acre (2 rangs de grains x 10 grains de longueur x 32 000 plants par acre ÷ 95 000 grains par boisseau). <\/p>\n\n

Pour les producteurs de l’Ontario, voici un excellent outil de suivi que j’utilise moi-même et que vous pouvez trouver ici<\/a>.  Inscrivez vos champs et suivez vos activités avec les étapes correspondant à sa croissance. <\/p>\n\n
