Controlled-Release Fertilizer and Container Volume to Produce Inga laurina Seedlings

This study evaluated the production of Inga laurina (Sw.) Willd seedlings in 110 and 280 cm3 tube containers growing doses (0, 3, 6 12 kg m-3) controlled-release fertilizer (CRF) (15-09-12) their performance at 5 months after outplanting. The experiment was conducted using a randomized split-plot design, 2 x 4 arrangement (tube volumes CRF doses). Stabilized sewage sludge from urban origin used as substrate. It assessed growth biomass nursery, well survival Containers between to m-3 produced less time, with higher biomass. At outplanting, presented acceptable mortality rate equal or greater than 3 CRF, respectively, for tube.
