The productivity and health of horticultural crops depends on the ability of the plant cover to intercept light energy. This ability is a function of the amount of leaf area, the architecture of the vegetation cover, and plants' ability to convert light energy. One estimate of a crop's ability to capture light energy is the leaf area index (LAI). Introduced in 1947, the concept of the LAI was defined as the ratio of leaf area to a given unit of land area. Today, understanding LAI is critical for successful crop management.
