Estimating alfalfa yield and nutritive value using remote sensing and air temperature
Field Crops Research(2018)
摘要
•Canopy reflectance wavebands can be selected to predict alfalfa yield and nutritive value.•Integrating canopy reflectance with air temperature improved model utility.•Growing degree units with a temporally graduating base temperature improved predictions.•Remote estimations were equally or more accurate than phenology-based estimations.
