Estimated cumulative probability (%) of belonging to one of the categories considered for evaluated vigour status: zero seedlings dead, one seedling defoliation higher than 50%, two seedlings defoliation lower than 50%, and three seedlings completely healthy. It was only represented factors or interactions with statistically significant differences. The model has proved to be significant for planting date (DP), measurement date (DM) and the interaction between DM and K dose
