Abstract
An analysis of spatial variation in the specific nitrogen content of leaves from different positions within a canopy is developed. It is used to examine data obtained for contrasting crop species; the legume crop guar (Cyamopsis tetragonoloba), and crops of a forage sorghum. The analysis distinguishes two components of the leaf nitrogen content: one associated with the metabolic apparatus within the leaf tissues and the other with structural elements of the leaf. The analysis allows the spatial variation in specific leaf nitrogen content to be quantitatively described.Keywords
