Agricultural sustainability across economic, environmental, and social domains is of great importance for food security and the continuation of human societies. This is especially true for potato (Solanum tuberosum), a globally important crop used to produce tubers rich in vitamins, minerals, carbohydrates, fiber, and protein. In many growing regions, potato production faces challenges from plant viruses and in-season nitrogen fertilizer management. Specifically, Potato virus Y (Potyviridae, PVY) is a detrimental plant virus that poses a significant threat to potato producers on a global basis. Industry stakeholders currently manage PVY infection levels via insecticide applications, regional seed certification programs that rely on field scouting to visually assess individual plants for infection status, and destructive and costly tissue sampling coupled with laboratory assays. Despite these efforts, PVY continues to confound potato industry stakeholders resulting in economic harm. Additionally, nitrogen is a vital macronutrient essential for potato production that is often managed with resource-intensive destructive tissue sampling in an attempt to track seasonal plant nitrogen status. Remote sensing and machine learning present opportunities for the development of new tools to meet these challenges. This work outlines efforts and results to gather data and develop Artificial Neural Network (ANN) classifiers as Multilayer Perceptron (MLP) and Convolutional Neural Network (CNN) architectures to differentiate potato plant canopies infected with PVY from non-infected counterparts based on spectral features. MLP modeling yielded high accuracy metrics of 0.894 and CNN model testing resulted in an accuracy of 0.833. Further analysis was conducted to identify important spectral wavelengths to support future sensor development and industrial applications. Additionally, data quantifying spatiotemporal potato petiole nitrate (NO3) concentrations were collected to support ANN development using publicly available climate and remote sensing features achieving mean coefficient of determination (R2 ) scores between actual and predicted values of 0.557 during replicated testing.
