High-Throughput Phenotyping for Soybean Iron Deficiency Chlorosis Using an Unmanned Aircraft System: Applications in Breeding, Agronomy, and Genetics
… to IDC, a task traditionally done with a 1–5 visual rating scale. The visual rating scale is subjective and, because it is time consuming and laborious, can typically only be accomplished once or twice during a growing season. The goal of this study was to use an unmanned aircraft system (UAS) …

Optimization of Pavement Marking Performance
… were evaluating using retroreflectivity and visual rating. From the collected data, degradation models were created using exponential models presented in the literature. The degradation models were implemented by using practical methods for assessing pavement marking retroreflectivity and …

Screening Diverse Soybean Germplasm for Water-logging Tolerance
… WLT for genotypes was assessed using a 0 to 9 visual rating based on severity of plot damage with 0 being no damage and 9 being 90% of the plot severely damaged to plot death. Differences in WLT ratings were significant in both 2009 and 2010, despite different weather conditions in 2009 and …

Soil and tissue tests for determining nitrogen status of corn
… N content of plants collected at the same time;A visual rating system was developed and calibrated for midseason evaluations of N status. The system is based on firing, the premature death of lower leaves. The system was shown to be at least as reliable as a tissue test based on the N …
