A Nitrogen response of leaf area index (LAI) for 44 maize hybrids collected from three replicate plots in Urbana, Illinois on July 25, 2023. B Correlations among the traits collected by the robot at multiple times during the 2022 and 2023 seasons, manual measurement of ear and plant height, and the component traits for nitrogen use efficiency. C Regression between stalk biomass predicted from robotically collected traits and manual measurements from the same plots collected in 2022.
