Abstract

Reflectance spectra over the wavelength range 0.4-2.5 micrometers were acquired during each of the major development stages of spring wheat canopies. Treatments in the experiment included planting date, nitrogen fertilization, cultivar, and soil moisture. Agronomic characterization of the wheat canopies included measurements of maturity stage, plant height, fresh and dry biomass, leaf area index, and percent soil cover. Analysis of variance, correlation, and regression analyses were used to relate the agronomic variables to reflectance. -from Authors
