Phosphorus performs primary functions in the metabolism and physiology of plants. Therefore, the objective of this study was to evaluate the influence of levels of phosphorus over the morphology of clones of conilon coffee trees. The experiment consisted of a 13 x 4 factorial scheme, with three replications, with the factors: 13 clones of the clonal cultivar 'Vitoria Incaper 8142', and four levels of phosphorus fertilization (0, 50, 100 and 150% of the recommended P2O5) in a completely randomized design. Plant height, stem diameter, leaf area, length and volume of roots analysis were performed. The increase in the levels of phosphorus in the soil caused an increase in the values of all variables for the cultivar 'Vitoria Incaper 8142'. However, there were different behaviors among the clones according to the levels of phosphorus.
