| 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... |

| ABSTRACT Information on the production of seedlings and initial growth of pomegranate irrigated with saline water is scarce in the Brazilian semi-arid region. The objective of this study was to assess the effect of irrigation water salinity levels on the growth and tolerance of pomegranate seedlings. The experiment was conducted in a greenhouse, located at the Federal Rural University of the Semi-Arid Region, Mossoró, RN, Brazil. A randomized block design with five treatments [electrical conductivities of irrigation water (ECw) of 0.6, 3.0, 6.0, 9.0, 12.0 dS m-1] and five replicates, with three plants per plot, was used. At 120 days after sowing, the following characteristics were evaluated: shoot, root and total lengths (cm); stem diameter (mm), dry mass... |

| ABSTRACT ‘Pitombeira’ does not have organized cultivation, thus requiring information related to the production of seedlings, particularly in relation to chemical fertilizer. In this context, an experiment was conducted in order to define the best dose of nitrogen (N), using urea as N source, to be applied in ‘pitombeira’ seedlings. The experimental design was complete randomized blocks with four replicates and ten plants per plot, testing five N doses (0, 400, 800, 1.600 and 3.200 mg dm-3). Data were submitted to analysis of variance and regression. The non-destructive measurements (number of leaves, stem diameter, shoot length and the ratio between shoot length and stem diameter) were evaluated at 30, 60, 90 and 120 days after transplanting (DAT). In... |
