Abstract
Holbert and Koehler (1924) found that the resistance of maize roots to vertical pull was correlated with resistance to lodging. To measure the force required to uproot the maize plants, simple root-pulling machines have been constructed (Snell, 1966; Craig, 1968; Ortman et al., 1968). In principle a sash cord or a leather strap is placed around the base of the stalk and by a hand-powered winch the force necessary to pull the stalk out of the soil with the main part of the roots is measured by a tensiometer.
