Description	A rising plate meter (RPM) is an instrument used for measurement of compressed sward height and estimation of yield on grasslands. The aim of this study was to investigate the use of a RPM to evaluate lucerne height as an agronomic trait enabling yield estimation. Compressed height (CH), stem length, plant and stem density, and yield measurements were recorded from the late-vegetative stage to flowering in the first cut, and from the late-bud stage to flowering in the second and third cuts, during three successive years. For lucerne maximal stem-length prediction, CH could be used successfully (with R2 over 0.90) in developmental stages before flowering, and for stem lengths up to 80 cm, irrespective of stand density or order of cut. The dry matter yield of lucerne was better predicted using CH (R2 = 0.72) than maximal stem length (R2 = 0.53). The recommended number of observations was 7-9 per treatment in the first cut, and twice this in subsequent cuts due to higher variability in stand structure.
