Description	The goal of this study was to compare the growing degree-days (GDD) and predictive equations for alfalfa quality (PEAQ) for the prediction of lucerne quality and to test their accuracy and suitability within the first cut period in central Bohemia. In 2004 - 2007, the measurement and sampling were repeatedly realized from the late vegetative to the early bloom stages in six replicates. For the GDD model across the years, the obtained R2 for NDF, ADF and CP were 0.40, 0.57 and 0.65, respectively. It seems that forage quality response on accumulated GDD was related to stand development and it could be the reason for low R2 across all the years. For the PEAQ model, R2 were 0.62, 0.92, and 0.85, respectively. Similarly with the GDD model, the effect of stand development across the years on changes of slopes of the equations was observed. The count of stems per plant, density of stems per m2, dry matter yield and the average stem weight improved the NDF content prediction within a four year period.
