Abstract

An experiment was conducted in which spectral and agronomic measurements were collected from corn canopies under four nitrogen treatment levels at the Purdue Agronomy Farm on 11 dates during 1978 and 12 dates during 1979. Spectral measurements over the 0.4 to 2.4 micrometre wavelength region were acquired with a spectroradiometer and used to compute reflectance factors. Agronomic data collected included biomass, leaf area index, plant height, crop development stage, and percent soil cover. Data were analyzed to determine: 1) the relationship between the spectral responses of canopies and their agronomic characteristics, and 2) the spectral separability of the four treatments. -from Authors
