Salt sensitivity of corn at various growth stages

As a followup to the field test of salt tolerance of corn, we attempted to determine in greenhouse studies the salt sensitivity of corn at various growth stages. If corn is more sensitive during one stage than another, the salinity of the irrigation water could be regulated during the season to minimize salt injury during the more sensitive stage. Standards are needed, particularly during droughts and during the later part of the growing season when the water supply may be limited.
