Abstract
The present device enables measurement of the susceptibility of corn plants to root lodging. The device is used to push over a corn stalk and the force used to push over the stalk, and the vibration of the stalk caused by the push are recorded. As material breaks in the stalk, an accelerometer, measures stalk vibration response to the breaking events; the data is then recorded to allow quantitative measurements of the susceptibility of corn plants to root lodging. This allows meaningful comparisons of various hybrids at early stages of hybrid evaluation and advancement.
