Because of their distichous growth habit, the foliage structure of individual corn ( Zea mays L .) plants can be diagrammed by placing them against a flat surface and outlining leaf positions on the surface by means of a marking pencil. A method is described whereby measurements made in such a manner are used by a computer program to predict the canopy characteristics of identical corn plants in various planting arrangements. The program output includes quantitative two‐dimensional descriptions of plants placed in different row‐width planting patterns, plus a measure of the leaf area and leaf angle characteristics of the various vertical layers of such canopies. Typical results with two common hybrids are presented.
