The objective of this research was to evaluate the reaction of loquat rootstock seedlings to different doses of magnesium thermophosphate. Five magnesium thermophosphate doses in the substrate were studied: 0.0 kg m-3; 2.5 kg m-3; 5.0 kg m-3; 7.5 kg m-3; and 10 kg m-3. The experimental design was complete randomized blocks, with five treatments, four replications and five plants per plot. When the rootstock seedlings were in conditions of being sent to the field, 180 days after sowing, the following variables were evaluated: plant height (cm), root length (cm), number of leaves per plant, and aerial part, root, and total dry matter (g). It was possible to verify that, for the formation of loquat rootstock seedlings, the use of the thermophosphate in doses of up to 5.0 kg m-3 is feasible, generating seedlings with a higher level of aerial part and root dry matter.
