Growth and reflectance characteristics of winter wheat canopies [PDF]
A valuable input to crop growth and yield models would be estimates of current crop condition. If multispectral reflectance indicates crop condition, then remote sensing may provide an additional tool for crop assessment.

Measuring leaf area index from colour digital image of wheat crop
Journal of Agrometeorology, 2016 Leaf area index (LAI) is an important physiological trait that determines solar radiation interception and thus biomass. In this study leaf area index (LAI) was estimated from vertical gap fraction derived from top-of-canopy digital colour photography ...
