Although the mechanisms of sorghum and maize adaptation to drought are generally well understood, little is known about the response of newly developed sweet sorghum genotypes to water deficits, especially at the root level. Thus, the objective of this study was to determine the rooting and canopy characteristics of a sweet sorghum hybrid, Sucro 506, compared to ethanol maize at two levels of water restoration. Root growth was correlated to the above ground biomass and...
