Hyperspectral remote sensing of yellow mosaic severity and associated pigment losses in Vigna mungo using multinomial logistic regression models

► Reflectance at 669, 505 and 510 nm were found sensitive to yellow mosaic disease. ► Disease caused significant loss of chlorophyll, but least change in relative water content. ► Spectral reflectance ratios R571/R721 and R705/R593 had best fit with chlorophyll. ► Developed logistic regression models with spectral ratios for disease assessment.
