                         response of common beans desiccated with diquat and 
                         glufosinate-ammonium (GLA) using a hyperspectral terrestrial 
                         sensor and report how the desiccants influence dry bean visual 
                         appearance. Bean plants were desiccated with two different types 
                         of diquat and GLA desiccants. After the measurements of the 
                         spectral curves were carried out, from these values the indices of 
                         vegetation and derivatives were calculated, the chlorophyll 
                         content of the leaves on the days of the campaign was also 
                         measured. After harvesting the grains, some qualitative variables 
                         of the grains, such as cooking time and color, were evaluated 
                         Vegetation indices (VIs) in the near-infrared and mid-infrared 
                         regions of the spectrum (wavelength locations of 705, 750, 860, 
                         and 1240 nm) were significantly different between desiccant 
                         treatments (p<0.05) two days after application (DAA). Desiccant 
                         application caused chlorophyll degradation as detected at the 
                         wavelength of 650 and 800 nm at DAA 1. The red edge and first 
                         derivatives showed that crop injury was higher in the diquat 
                         treatment because peak magnitude for this treatment became smaller 
                         over time. The desiccant application negatively affected seed 
                         quality, resulting in smaller Hue values and longer cooking time 
                         (CT). Hue angle correlated negatively with plant water content 
                         variation and CT Our results suggest that hyperespectral 
                         terrestrial sensing can differentiate the effects caused by the 
                         desiccants, showing that ammonium glufosinate causes less damage 
                         to seed quality and the water loss is like the control group.",
