Il n'y aurait pas de temps à perdre

"Si la sécheresse, par exemple, survient tôt dans le développement d’une plante, elle peut former moins de pousses latérales.

Pour maintenir un rendement élevé, il faut aussi des racines saines, et de nombreuses variétés de céréales

ne peuvent pas bien pousser dans un sol sec. il faut donc à identifier les caractéristiques génétiques des systèmes racinaires les plus résistants. Merci

Siham Zaaboubi

et pour assurer un développement des racines saines, il faut se baser sur un cycle de croissance sain (loin des ajouts chimiques)?????
