Abstract
To quantify and understand several of the potential sources of variation in spectral measurements of crops, an experiment was conducted at the Williston, North Dakota, Agricultural Experiment Station in 1977. The effects of available soil moisture, planting date, nitrogen fertilization, and cultivar on reflectance of spring wheat canopies were investigated. Spectral measurements were acquired on eight dates throughout the growing season, along with measurements of crop maturity stage, leaf area index, biomass, plant height, percent soil cover, and soil moisture. Planting date and available soil moisture were the primary agronomic factors which affected reflectance of spring wheat canopies from tillering to maturity. - from Authors
