The laser-induced fluorescence (LIF) of a rice plant is evaluated as a means of remotely detecting a leaf color and estimating a plant growth. A leaf color of a rice plant growth changes according to a plant growth. The leaf color is influenced by a quantity of chlorophyll contained in the leaf. Fluorescence intensity of in-vivo chlorophyll is changed by an amount used manure. Until now measurements of the leaf color have been carried out in a rice field using a color scale. There are some differences in its observation owing to the observer's individual character. In the LIF system, the fluorescence spectra of in-vivo chlorophyll are excited with a nitrogen laser emitting at 337 nm. By detecting changes in fluorescence intensity at 684 nm and 739 nm concerned with photosynthesis, we estimate the rice plant growth.
