Coefficients of determination (r²) of forage neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP) concentrations (%), aboveground biomass (Mg ha^–1), and CP availability (CPA, kg ha^–1) with canopy reflectances in broad-wavebands of blue (450–520 nm), green (520–600 nm), red (630–690 nm), near infrared (NIR, 760–900 nm), short-wave infrared 1 (SWIR1, 1550–1750 nm), and short-wave infrared 2 (SWIR2, 2080–2350 nm) (n = 144).
