Industrial hemp for fiber and grain production
Flown by John Scott, Digital Agriculture Extension Coordinator, Purdue Extension
Images of industrial hemp in its first year were taken to understand the crop in terms of fiber and grain production. The first image is a truecolor or RGB image of the plots, while the other three are plant health maps all measuring vegetation index values. The normalized difference red edge (NDRE) is more sensitive to chlorophyll content, changes in leaf area and soil in the background and shows greatest detail at this stage of hemp development.
