Stemflow on maize: A stemflow equation and the influence of rainfall intensity on stemflow amount

Summary Stemflow on maize was measured in the laboratory and in the field. The results of these experiments were compared with predicted values from a stemflow equation built up for maize. Different intensities were used to examine the influence of rainfall intensity on stemflow amount. Intensity ranged from about 1 mm/h to 90 mm/h. It appeared from these experiments that maize plants can concentrate large amounts of stemflow. Higher intensities cause relatively more stemflow. The stemflow equation can predict fairly well the quantities of stemflow on maize.
