SPECTRAL REFLECTANCE PATTERNS OF FLOODED RICE

Spectral reflectance of several rice varieties with different morphological characteristics was measured at Thematic Mapper wavebands using a portable radiometer. The visible and near infrared response of rice growing in flooded soils was similar to that of other crops growing in dryland conditions. At middle infrared wavelengths, however, reflectance either increased with leaf area index or remained relatively unaffected in contrast to what has been found for other crops. Results of the research suggest that LAI of conventional rice research plots may be monitored using field spectral measurements.-from Authors Evapotranspiration Lab, Dept of Agrnomy, Kansas State Univ, Manhattan, KS 66506, USA.
