| Description: | With high commercial and environmental value, Enterolobium contortisiliquum (Vell.) Morong is a tree species of the family Leguminosae - Mimosoideae, known as tamboril and used for civil construction, timber products, urban afforestation, and reforestation of degraded areas. In order to analyze the response of the species to the composite sewage sludge (LEC) in relation to the commercial substrate (SC), 5 substrate combinations were used: S1 (100% SC); S2 (75% SC + 25% LEC); S3 (50% LEC + 50% SC); S4 (75% LEC + 25% SC) and S5 (100% LEC), each with 4 replicates. These 5 substrate combinations were submitted to 3 irrigation slides: L1 (36 mm/day), L2 (72 mm/day) e L3 (108 mm/day). Biometric parameters (height, diameter, number of leaves), growth speed, dry biomass, Dickson Quality Index, and height/diameter ratio were measured. Based on the values obtained and on the upper averages for all the parameters evaluated, it is recommended to use S5, composed of 100% LEC with L1. |
