Limited root development

Digging up both lodged and standing plants revealed that the lodged plants had limited root development. Often referred to as rootless or floppy corn, the poor root development can have many causes. Erosion or compaction of the seedbed before the nodal roots become established may prevent the nodal roots from penetrating the hot, dry surface soil. Sidewall compaction or extremely shallow planting can elevate the crown with a similar result.
