Imaging spectroscopy is an established, non-destructive, method for estimating alfalfa yield and monitoring crop nutrient status. Our goal was to utilize unmanned aerial vehicle (UAV)-based hyperspectral sensors for germplasm screening of non-dormant alfalfa under two contrasting nitrogen levels (0 vs 30 kg/ha per harvest) for biomass yield and persistence in Florida. We collected ground-based and airborne sensors for high-throughput phenotyping and developed genomic prediction models by leveraging genomic resources in alfalfa developed by the breeding insight project. We will present the image processing pipeline for nitrogen/abiotic stress detection using hyperspectral sensors.
