This experiment was conducted in greenhouse nursery (50%) located in the orchard, Federal University of Lavras (UFLA) in order to assess the initial response of seedlings of cherry-the-woods to the effect of doses of single superphosphate. The design was a randomized blocks with four treatments, four repetitions and sixteen plants per plot. We used 4 doses of single superphosphate (0, 2.5, 5.0 and 10.0 kg/m3 of substrate). Thefertilization with the single superphosphate was made in the substrate, at the time of filling the bags for production of switches. We evaluated the characteristics: height changes (cm), the root length (cm), number of leaves per plant, dry matter of shoots, roots and the total (g / plant). There was a significant effect of doses of single superphosphate for all characteristics except for the length of root and dry root. Since the doses of 5.29, 10.0, 5.86 and 6.15 10.0 kg/m3 of the substrate that provided greater height (17.18 cm), number of leaves (9.85); dry of shoot (2.04 g) and total dry weight (2.76 g), respectively.
