The study was developed with the objective of characterizing the behavior of the morphology of the Lysiloma sabicu Benth. plant grown in a nursery on different organic substrates and with the use of container technology. Three combinations of substrates made from mixtures of organic compost, worm humus and cow dung were tested to determine in which way it was feasible to achieve better plant quality with the use of this technology. The morphological variables measured were: height, root collar diameter, dry biomass, as well as root system attributes. From these values, the morphological indices were calculated: Slimness, PSA/PSR Ratio, and Dickson's Quality Index. The results obtained showed that there was a differentiated effect on the plants' morphology, depending on the substrate in which they were cultivated, and that it was S1 formed by 50 % organic compost + 25 % worm humus + 25 % cattle manure (Co-50 %+Hl-25 %+Ev-25 %) which provided the best values in the parameters studied.
