| Abstract/Contents: | "Visual colour assessments are often used by practitioners and researchers as an indirect measure of the nitrogen (N) status of turfgrasses. Although visual colour assessments are fast and simple to perform, they are subjective. A study was conducted to determine if the Minolta CR-310 Chroma Meter can detect colour changes in turf fertilised with different rates of N and predict N concentrations in turf foliage based on colour measurements. Results showed that hue angle (H) values generated by the CR-310 typically increased with increasing rates of N fertilizer and were strongly associated with foliar N concentrations (r = 0.84 in 1995 and 0.87 in 1996). A linear relationship between H and foliar N concentrations was observed in 1995 (RĀ² = 0.83), whereas a curvilinear relationship was found in 1996 (RĀ² =0.94). This study demonstrated that the CR-310 can detect differences in the colour of turf fertilised with different rates of N and can, with reasonable accuracy, predict the foliar N concentration of creeping bent (Agrostis stolonifera L.) maintained as a golf course fairway. Additional testing on other cultivars, at different locations, and under a wider range of N concentrations is necessary to determine the versatility of the instrument in assessing foliar N concentrations of turfgrasses." |
