Abstract

This aim of this work was to evaluate the initial growth of Cordia trichotoma seedlings, submitted to different sizes of recipients and doses of controlled-release fertilizer (CRF). This experiment was performed in a greenhouse, and evaluation was done in factorial scheme using two volumes of recipients (110 and 180 cm3) combined with five doses of CRF (0 (controlled); 2.5; 5.0 and 7.5 g L-1 de substrate). The experimental design was completely random with four repetitions each evaluated in factorial scheme. Significant interaction was observed between the size of the recipient and the doses of CRF for most analyzed variables. It indicated that, the quantity of fertilizer to be used depends on the size of the recipient, emphasizing that in the conditions in which the seedlings were produced; the minor volume of substrate does not cause restrictions on growth. It is perceived that most evaluated parameters need higher doses than the maximum provided, in at least one of the recipients, demonstrating elevated nutritional requirement of the species during the nursery phase. The recipient of 110 cm³, combined with the dose of 7.5 g L-1 of CRF is recommended because of the economy of substrate, nursery space and practicality of transportation.
