Résumé
Wheat and cotton are grown in a wide range of water regimes (from dryland to full irrigation) and produce grain, forage and fiber in the southern Ogallala Aquifer region. Due to their relatively higher drought tolerance than other crops such as corn and soybean, wheat and cotton fit scenarios of dryland and limited irrigation production. Like other crops, wheat and cotton yields are greatly reduced by drought stress, which is inevitable under dryland and limited irrigation conditions. Therefore, improving drought tolerance and water use efficiency (WUE) is extremely important for sustaining production. Selection and adoption of drought tolerant cultivars remains a critical strategy for crop management under water-limited conditions.

Objectifs
Correlate spectral characteristics collected from an UAS platform with ground-based leaf water status, gas exchange, chlorophyll fluorescence and stomatal conductance.Correlate crop growth rate data from the same platform with yield.Incorporate the crop growth rate data into an artificial intelligence model to predict future grain and lint yield.Determine how phenotypical traits affect the economic profit potential of wheat and cotton for producers due to drought resistance and differences in quality
