Other claims from this paper (5)
- Method / resource Digital image analysis accurately quantified hue, saturation and brightness of turf-color chips, with respective r2 values 0.99, 0.96 and 0.97.
- Observation Nitrogen treatments differed significantly in hue, saturation and brightness in creeping bentgrass.
- Observation Nitrogen treatments differed significantly only in hue in zoysiagrass.
- Observation Bermudagrass cultivars differed significantly in hue and saturation.
- Method / resource Dark green color index values strongly agreed with visual ratings.
