Assessing Hail Damage to Corn

This publication discusses when corn is most susceptible to hail damage, determining yield loss due to stand reduction and defoliation, determining direct ear damage, bruising and stalk damage, and estimating total yield loss. Tables are included listing the total feet of row required to make one-one hundredth acre at various row spacings, the estimated percent corn yield loss due to stand reduction occurring through the tenth-leaf stage of growth and the estimated percent corn yield loss due to defoliation occurring at various stages of growth. Illustrations are also provided showing a corn plant in the 5-leaf growth stage and fifth leaf attachment.
