Resumo: | ABSTRACT The objective of this study was to evaluate the growth of ‘jurema-branca’ seedlings (Piptadenia stipulacea (Benth.) Ducke.), irrigated with effluent from fish farming in order to meet the nutritional demand in the initial growth stage. The treatments consisted in the dilution of fish farming wastewater in different concentrations (0, 25, 50, 75 and 100%) with supply water. Seeds were sown in 0.9-L polyethylene bag containing a mixture of soil and manure. At 54 days after sowing the shoot length, stem diameter, height/diameter ratio, number of leaves, leaf area, unit leaf area, dry matter of stem, leaves, shoots, roots and total, chlorophyll content index and Dickson quality index were evaluated. The growth of ‘jurema-branca’ seedlings is favored by the dilution of 25% of fish farming wastewater in the supply water. Using up to 25% of the concentration of the fish farming effluent does not significantly affect the dry biomass accumulation in ‘jurema-branca’ seedlings, in relation to the control. The reuse of fish farming wastewater diluted at proportion of up to 25% is a viable alternative to meet the water demand in the production of forest seedlings.
