Time-Resolved UAV Multispectral Characterization of Cultivar-Dependent Yield Variation in Rice Under Planting-Density Treatments
UAV multispectral imagery can support rice yield estimation, but spectral–yield relationships may change with cultivar and planting density. We evaluated three japonica rice cultivars under five planting-density treatments in a split-plot experiment and collected UAV multispectral imagery on 13 dates. We examined five...
